			<content:encoded><![CDATA[<p style="text-align: justify;">Making mistakes is part of the process of building a company. Quickly recovering from them is what&#8217;s most important. It&#8217;s all part of the adventure of entrepreneurship, which will require all of your stamina, drive and determination.</p>
<p style="text-align: justify;">When you notice an opportunity that has never occurred to anyone else, there are certain steps to turning your vision into reality. You must formulate an innovative business plan, find funding, hire the right people to carry out the plan, and then step back from your role in the business at exactly the right moment.</p>
<p style="text-align: justify;">Let&#8217;s take a look at these steps, and also at ways to avoid some of the most common mistakes new entrepreneurs make.</p>
<p style="text-align: justify;">Step 1: Stay on Target &#8211; Stay Focussed:</p>
<p style="text-align: justify;">A mistake often associated with the first step in Business is an entrepreneur&#8217;s inability to clearly and concisely convey his idea to others such as potential investors, partners or potential employees. An associated error is lack of focus. Clearly define your goals and strategies, then establish a timeline. Don&#8217;t let the other possibilities or hazy dreams distract you from achieving your goal.</p>
<p style="text-align: justify;">Step 2: Be Realistic About Costs</p>
<p style="text-align: justify;">Don&#8217;t underestimate the cost of starting your new businesses &#8212; you&#8217;ll just diminish your chances of success. Keeping your expenses under control is vital, but don&#8217;t confuse capitalization with costs. As we all know, There are many new businesses in the market who do not even have the funds for one year of expense. Under-funded new businesses are doomed to fail from the outset.</p>
<p style="text-align: justify;">Step 3: Hire the People You Need, Not the People You Like</p>
<p style="text-align: justify;">As tempting as it may be to staff your new business with friends and relatives, this is likely to be a serious mistake. If they don&#8217;t work out, asking them to leave will be very tough. One of your goals should be to find a manager who truly shares your vision, and to whom you can someday confidently hand the reins so that you can carry out the next step.</p>
<p style="text-align: justify;">Step 4: Know When to Say Goodbye</p>
<p style="text-align: justify;">A great entrepreneur knows when the time has come to leave the CEO/M.D. role. Its not easy, but it has to be done. Very few Business owners make great managers. Stepping back doesn&#8217;t mean turning your back on your business. Founders / Owners shouldn&#8217;t hesitate to re-insert themselves into their businesses when necessary</p>

			<content:encoded><![CDATA[<p style="text-align: justify;"><strong>Wedge Anchor Introduction</strong></p>
<p style="text-align: justify;">&#8220;Wedge Anchor&#8221; is a generic  term for a type of anchor used to fasten a variety of materials to  concrete. Some companies have different brand names for their wedge  anchors such as Kwik Bolt, Power Stud and Thunderstud. The different  brands of wedge anchors all work on the same principles, are made from  the same basic materials, and provide similar high quality performance.</p>
<p style="text-align: justify;"><strong>What is a Wedge Anchor?</strong></p>
<p style="text-align: justify;">Wedge  anchors consist of two separate pieces that are permanently  pre-assembled into a single unit. The first piece is a carbon steel rod  that is threaded for a portion of its length. The opposite end, the  installed end of the anchor, has a necked-down diameter, or conical  space, that tapers outward back to the rod&#8217;s full diameter.</p>
<p style="text-align: justify;">The  second piece of the wedge anchor is a steel clip, or sleeve, that is  permanently assembled around the conical section of the rod. Each wedge  anchor also requires a nut and washer to complete installation.</p>
<p style="text-align: justify;">Wedge  anchors can be used in numerous applications as long as the base  material is solid concrete. Unlike many other concrete fasteners, the  wedge anchor cannot be used in brick or block.</p>
<p style="text-align: justify;">The wedge anchor is  simple to use and is available in a wide variety of diameters and  lengths. Wedge anchors can be used in both light and heavy duty  applications. A 1/4&#8243; x 1-3/4&#8243; wedge anchor, for instance, would be  utilized in a light duty application, while a 1-1/4&#8243; x 12&#8243; anchor would  be used in a situation that requires a heavy duty anchor.</p>
<p style="text-align: justify;"><strong>How Does a Wedge Anchor Work?</strong></p>
<p style="text-align: justify;">Again,  wedge type concrete fasteners are designed for use in solid concrete  only. They are designed to go into a pre-drilled hole in concrete.  Once  installed, these wedge anchors can not be removed without destroying  the concrete. The size of the anchor is always equal to the size of the  hole that needs to be drilled into the concrete. The tolerance between  the hole and the anchor is very tight. As the anchor is hammered into  the hole, the clip is recessed in the gap of the conical space, allowing  the anchor to penetrate the hole. To set the anchor, the rod must be  pulled-up (which occurs while the nut is being tightened), making the  clip move outward on the tapered space, wedging itself between the rod  and the wall of the hole.</p>
<p style="text-align: justify;">Since the hole tolerance is critical in  the performance of the wedge anchor, it is important that the correct  drill and drill bits are used.  A hammer drill should be used rather  than a standard power drill because it creates a better quality hole. A  carbide-tipped masonry bit should also be used because they are  specifically designed for use in hammer drills and meet ANSI standards.</p>
<p style="text-align: justify;"><strong>Wedge Anchor Holding Values</strong></p>
<p style="text-align: justify;">When  anchoring into concrete, wedge anchors are an excellent choice because  of their holding values.  The holding power of the wedge anchor, as with  any anchor, is always dependent on the quality of the concrete. As a  rule of thumb, a safety factor of 4:1, or 25%, is generally accepted as a  safe working load. Holding values are also derived from the depth of  the embedment- the deeper the embedment, the better the holding values.  The wedge anchor must be embedded into the concrete up to or past the  minimum embedment depth to obtain published holding values. It is also  essential to ensure that the anchors are not placed too close together  or too close to an unsupported edge.</p>
<p style="text-align: justify;">The pressure exerted on the  concrete by a wedge anchor can be best described as cone-shaped, with  the small end of the cone being the inserted end of the anchor and the  large end of the cone being at the surface of the concrete. If two wedge  anchors are set too close together, the pressure from the two anchors  would intersect, decreasing the holding values of both anchors. These  same factors apply when placing an anchor near an unsupported edge. It  is possible for the concrete to crumble under pressure if the concrete  anchor is placed too close to the unsupported edge.</p>
<p style="text-align: justify;">The general  recommendation is that an anchor should be placed no closer than five  diameters from any unsupported edge.  For example, a 1/2&#8243; diameter  anchor should be at least 2-1/2&#8243; from any unsupported edge of concrete.  Also, two anchors should never be set less than ten diameters from each  other. That is, two 1/2&#8243; diameter wedge anchors should be placed at  least 5&#8243; apart.</p>
<p style="text-align: justify;"><strong>Determining the Correct Size Wedge Anchor to Use</strong></p>
<p style="text-align: justify;">The  diameter of the wedge anchor required for an application usually  depends on the size of the hole in the fixture to be fastened. The  &#8220;fixture&#8221; could be anything from a 2&#215;4 to a piece of angle iron, bracket  or steel plate. The hole size in the fixture is most often determined  by an engineer based on the necessary holding values for each particular  application.  It is imperative to ensure that the concrete wedge anchor  fits through the hole in the fixture.  A 1/2&#8243; wedge anchor is, in  reality, slightly larger than 1/2&#8243;.</p>
<p style="text-align: justify;">Each wedge anchor diameter is  available in a variety of lengths. The length required needs to be  determined for each application and is dependent upon the thickness of  the fixture to be fastened, plus the minimum embedment. To determine the  length of anchor needed, simply add the thickness of the fixture to be  fastened to the minimum embedment for the wedge anchor diameter being  used, plus the thickness of the nut and washer (typically the diameter  of the anchor is close to the thickness of the nut and washer).</p>
<p style="text-align: justify;">This  will give you the minimum length of anchor required. Using a longer  wedge anchor than necessary will increase the holding values, but may  increase your risk of drilling into rebar embedded in the concrete.</p>
<p style="text-align: justify;"><strong>Wedge Anchor Installation</strong></p>
<p style="text-align: justify;">The installation of the concrete wedge anchor can be completed by following the steps below:</p>
<p style="text-align: justify;">1.   Determine the correct length of wedge anchor required to ensure that  the minimum embedment is   met and ensure that the wedge anchor fits  through the hole in the fixture. The washer should also be larger than  the fixture hole.</p>
<p style="text-align: justify;">2.  Using the hole in the fixture as a template,  carefully drill your holes using a hammer drill and carbide-tipped  masonry bit.  The drill bit diameter should be the same as the wedge  anchor&#8217;s diameter. It is imperative that the hole be cleared of all dust  and debris.  This can be accomplished by using a wire brush, compressed  air or vacuum.</p>
<p style="text-align: justify;">3.  Place the washer and nut on the anchor, turn  the nut a couple of turns.  Not fully threading the nut protects the  threads of the wedge anchor when hammering into the hole.</p>
<p style="text-align: justify;">4.  Insert the wedge anchor into the hole through the hole in the fixture.</p>
<p style="text-align: justify;">5.   Carefully hammer the anchors into each hole ensuring that the threads  go below the surface of the concrete or past the edge of the fixture,  and that minimum embedment is met.</p>
<p style="text-align: justify;">6.  Tighten the nut &#8211; finger tight.  Use a wrench to tighten the nut 3 or 4 turns, or use a torque<br />
wrench to ensure they are tightened to the required torque value.  Do not over-torque, as the<br />
anchor will either spin in the hole or pull out of the hole.</p>
<p style="text-align: justify;">Please view this <a rel="nofollow" href="http://www.concretefasteners.com/anchors-fasteners/thunderstud-wedge/installation.aspx" target="_new">Wedge anchor installation video</a>.</p>
<p style="text-align: justify;"><strong>Wedge Anchor Torque Values</strong></p>
<p style="text-align: justify;">Wedge  anchors require a minimum torque to set.  Do not tighten the nut as  tight as possible. When setting a wedge anchor, it is important that the  nut only be screwed on finger tight. Each anchor diameter has a  required torque value to which it must be tightened.</p>
<p style="text-align: justify;"><strong>Length Identification Chart</strong></p>
<p style="text-align: justify;">Once  the anchor is properly set, all that is protruding above the concrete  is the nut, washer, and a portion of the threads. The diameter of the  embedded anchor can easily be determined by simply measuring the stud.  The length of the anchor, however, can be difficult to determine because  the depth of embedment may not be known. To help identify the length of  an installed anchor, an identification code has been developed. A  letter is stamped on the end of the threaded portion of the wedge anchor  to easily determine the length of the wedge anchor after installation.  This letter corresponds to the overall length of the anchor (in inches).</p>
<p style="text-align: justify;"><strong>Wedge Anchor Material Specifications</strong></p>
<p style="text-align: justify;">Concrete  wedge anchors are available in different types of steel as well as  different plating. The type of steel and plating to use is based on the  application&#8217;s environment. Zinc-plated carbon steel wedge anchors are  used in interior applications, where corrosion is not much of a factor.  The anchor, nut, washer, and clip are all made of zinc-plated carbon  steel. This type of plating is not recommended for use in ACQ treated  lumber.</p>
<p style="text-align: justify;">Hot-dipped galvanized wedge anchors are suited for  exterior applications where corrosion from water or moisture is a  concern. The anchor, nut, and washer are all made of carbon steel and  are hot-dipped galvanized. The clip is made of 303 stainless steel.   Hot-dipped galvanized wedge anchors are acceptable to use in ACQ treated  lumber.</p>
<p style="text-align: justify;"><a rel="nofollow" href="http://www.concretefasteners.com/anchors-fasteners/thunderstud-wedge/index.aspx" target="_new">Wedge anchors</a> are also produced in two grades of stainless steel. The 303 stainless  steel has excellent corrosive characteristics for exterior applications  and is resistant to many organic and inorganic chemicals, but should not  be used in a salt water environment. The anchor is made from 303  stainless steel and the nut, washer, and clip are made of 18-8 stainless  steel which is comparable to 303 stainless steel.</p>
<p style="text-align: justify;">The 316 series  of stainless steel has the best corrosion resistance and is typically  used in harsh environments. The 316 stainless steel anchors can also be  used in a salt water environment. All of the components in the 316  stainless steel wedge anchor are made from this resilient 316 steel.</p>
<p style="text-align: justify;"><strong>Overview</strong></p>
<p style="text-align: justify;">Wedge  anchors are an excellent choice when anchoring into solid concrete.  These anchors have excellent holding values and are available in a range  of materials and plating to meet the requirements of many applications.  It is important to make certain that the correct diameter and length  are used in each application to ensure that the wedge anchor is set  properly and safely.</p>

			<content:encoded><![CDATA[<p style="text-align: justify;">Being a steel erector each day can have its pros and cons. For the  most part, each erector experiences many of the same issues over and  over again. One of those issues is setting the low anchor bolts  correctly. Here is some information about setting low anchor bolts the  correct and incorrect way.</p>
<p style="text-align: justify;">There are many steel erectors each day  constructing very similar structures. Those structures usually have  problems that occur with many other projects the steel erector is  working on. One of the problems that continually occurs is setting the  anchor bolts.</p>
<p style="text-align: justify;">These bolts can sometimes be tricky to deal with.  Many times these bolts are set with their tops lower than the elevation  they are supposed to be set at. Or the top of the bolt can extend the  base plate and not allow full thread for the nut. This can certainly  make it difficult, but as you gain more experience you will become  better at dealing with these types of bolts.</p>
<p style="text-align: justify;">When the anchor bolt  is set low, many steel erectors call that, &#8220;short anchor bolts.&#8221; The  best way of resolving it is by making the bolt longer. Now, you might  ask, &#8220;how do I make it longer?&#8221; Well, the best way of extending the bolt  is to thread couplers and weld extensions to the bolt.</p>
<p style="text-align: justify;">Remember  that anytime you are doing a correction you do need to consult with the  structural designer. Consulting with the designer will help you make  sure everything is done according to the designer&#8217;s special procedures  so it is advised that you do consult the structural engineer.</p>

			<content:encoded><![CDATA[<p style="text-align: justify;">For those of you who don&#8217;t know what an anchor bolt is, it&#8217;s  usually an L shaped bolt that goes into the concrete and is used to  connect the bottom framing plates to the concrete slab, footing or  building foundation. But here are some of the things that you might not  know about your building foundation and metal bolts and how they can  work more efficiently together.</p>
<p style="text-align: justify;">Did you know that there are  different lengths of anchor bolts? Do you know that there are different  sizes of foundation bolts, for instance I&#8217;ve seen foundation bolts as  small as 3/8 of an inch and as large as three quarters of an inch. It&#8217;s  hard to imagine that we need so many different types of L bolts for our  building foundation.</p>
<p style="text-align: justify;">Now here&#8217;s something that even some builders  have a problem with. It&#8217;s not a big problem, but I&#8217;ve seen contractors  argue with structural engineers about which types of anchor bolts are  actually going to be required for one particular project. Now remember,  most builders don&#8217;t have the knowledge or the responsibility a  structural engineer might have, about building foundation, especially if  it ever failed.</p>
<p style="text-align: justify;">The biggest problem with contractors and builders  who think that they know more about building foundations and L bolts  than the structural engineers or even the city engineers, should try to  keep one thing in mind. They&#8217;re not responsible for any structural  problems that were assembled according to the building plans, but the  structural engineers are.</p>
<p style="text-align: justify;">The next time that you&#8217;re looking at a  set of blueprints and it calls out for a 7 inch minimum anchor bolt  embedment, make sure that you purchase the right L bolt&#8217;s for that  particular job. I&#8217;m not writing this article, because I&#8217;ve never seen  this happen, I&#8217;m writing this article, because I know someone who  installed the wrong anchor bolts on one of their projects. These L bolts  were later removed as the city building inspector requested a  correction for the change.</p>
<p style="text-align: justify;">The building inspector found the  problem and the contractor got the education. Even though the contractor  knew better, he still got the education.</p>

			<content:encoded><![CDATA[<div style="text-align: justify;">
<p>There is not much of a difference between horizontal and vertical  milling machines. Both of these equipments are indispensable in cutting  parts uniformly and quickly. These days&#8217; horizontal machines are  becoming more popular due to its overhead arm and its arbor driven  cutters. These are also very easy to operate with few steps to remember.  Some of the benefits of using horizontal milling machines are discussed  below:</p>
<p>Design and set up: If you are looking to manufacture  products which are cost-effective and of high quality, then a vertical  milling machine should be of great help. They have scientific designs  suitable for dealing with various hard materials. The time taken for  this process is minimal and so as the number of steps required operating  it. There is no need for a large set up to install these machines and  also no need to employ numerous workers. You can have substantially  savings on the labor cost, which is often the key setback in a  manufacturing environment.</p>
<p>Automation and programming: The  finished products of vertical machines are of finer quality, with better  finishing. As a result, you get the final output, just as you would  have planned. Majority of the modern horizontal milling machines are  completely automated and requires minimal human intervention. Prior  programming and automation result in minimal errors in production, with  25% less processing time.</p>
<p>Reduced processing time: These  equipments perform diverse functions just like a general machine as well  as other activities like tapping and boring. One milling machine  performs these in one operation. Advanced milling also reduces the need  for manual labor significantly, which significantly reduced the  operational cost unlike earlier times. These machines no longer require  multiple set ups and change in tools. Horizontal milling machines are  advanced and do not require frequent movement of parts, location wise.  These advancements have reduced delay in processing time drastically.</p>
<p>Arm  supports and clutters: Horizontal machines have features of arm  supports and clutters, which are driven by an arbor. These two features  help to add value in production. You should pay attention to reduce  incidence of accidents and ensure maximum safety. Maintenance of cutters  is required at a proper interval of time to maintain its sharpness.

<p>There are 13 different kinds of milling cutters used in various  milling machines. They each cut materials differently. They are: end  mill, roughing end mill, slab mill, face mill, hollow mill, slot drill,  ball nose cutter, side-and-face cutter, involute gear cutter, fly  cutter, woodruff cutter, dovetail cutter, and hob.</p>
<p>Milling cutters  are essential cutting tools needed in a milling machine. Different  types of milling cutters are available in many sizes and shapes to  efficiently perform any type of cutting work. Read on to know the  different types of milling cutters.</p>
<p>End mill</p>
<p>This is a tool  with cutting teeth on one end and on its sides. Made of a high speed  steel (HSS), the end mill cutter is the most common tool used in a  vertical milling machine.</p>
<p>Roughing end mill</p>
<p>A roughing end  mill removes a huge chunk of material in a wavy cutting pattern. This  cutting mill produces a rough surface finish and is also known as  ripping cutters. The wavy teeth minimize the vibrations and chatter  sounds that occur during the cutting process.</p>
<p>Slab mill</p>
<p>A  cylindrical cutting tool that can be used individually or with other  cutting tools for cutting horizontal surfaces, the slab mill is made  from a HSS.</p>
<p>Face mill</p>
<p>Face mill cutters are capable of  holding multiple tip inserts. This economical type of cutting tool has  tips that are can be replaced when they become blunt. A face mill can  perform various cutting actions due to the versatility of the inserts  and tips that it can work with.</p>
<p>Hollow mill</p>
<p>A hollow milling  cutter is a pipe shaped tool with thick walls. The cutting teeth,  however, are on the inside surface area. This cutting tool is  essentially used in finishing cylindrical protrusions.</p>
<p>Slot drill</p>
<p>A  slot drill is a cutting tool that directly cuts straight into a  material. It commonly has two or more fluted cutters and a singular  tooth located at the center of the end face. Slot drills are generally  used for making cuts in a keyway slot.</p>
<p>Ball nose cutter</p>
<p>The  ball nose cutter is a hemispherical end cutter with a similar function  to that of a slot drill. This is an ideal cutting tool for machines that  shapes three dimensional contouring forms and shapes. Ball nose cutters  are also commonly called ball mills.</p>
<p>Side-and-face cutter</p>
<p>The  cutting of a side-and-face cutter is located on its circumference and  side portion. They are available in different widths and diameters. The  side teeth functions to cut only one side of the material.</p>
<p>Involute gear cutter</p>
<p>This twelve teeth cutting gear comes in eight cutter sizes. A circular cutting tool, it has cutting edges on its circumference.</p>
<p>Fly cutter</p>
<p>A  fly cutter is an inexpensive tool that functions like a face mill. It  is composed of one or two tool bits that rotate to remove shallow and  facing cuts.</p>
<p>Woodruff cutter</p>
<p>Woodruff cutters are small tip cutters that are used in cutting keyways. It is an essential tool in key engineering.</p>
<p>Dovetail cutter</p>
<p>Dovetail cutters are cutting tools that produce a dovetail slot patterns.</p>
<p>Hob</p>
<p>Hobs  are cutters used in a hobbing machine. These cutters are used to make  gears abd provide the appropriate shape specification of each workpiece.  It is also important to consider the least cost and the correct cutting  specifications of a cutting work when choosing a milling cutter.  Remember to always work safely with the every cutting tool.</p>

			<content:encoded><![CDATA[<div style="text-align: justify;">
<p>In simplest terms, plasma cutting is the process of cutting any  electrically conductive metal by using high velocity of ionized gas  which is delivered from a nozzle. The high pressured ionized gas which  becomes the plasma, conducts electricity from the plasma cutting torch  to the work piece. The plasma while coming into contact with the work  piece heats and melts the material. Thus the metal pieces are cut  smoothly. As plasma cutting is perfect for cutting steel and non-ferrous  material, it is widely used in industries as well as by amateurs.</p>
<p>When  you are planning to buy a plasma cutting machine, certain guidelines  should be essentially followed. One of the main factors to consider is  the thickness of the metal that you are cutting. Generally the plasma  cutters are rated on their cutting ability and amperage. If you are  cutting metal with considerably less thickness, you must consider a  lower amperage plasma cutter. Likewise, you must use higher amperage  machines for thicker metals. Even though the smaller amperage cutter  would be capable of cutting metals of any thickness, the quality would  be lacking in thicker metal cuts. The optimal cutting speed of the  machine should also be considered before purchasing the cutter. A  machine with high amperage would cut the metal much faster than one with  low amperage.</p>
<p>In most plasma cutters, the pilot arc conducts high  frequency electricity through the air. This electricity would interfere  with computers or other equipments. So it would be better to select  lift arc method that eliminates the problems of high frequency starting  circuits. The plasma cutting torches consists of a number of plasma  cutting consumables that would require replacement. It is recommended  that a machine with lesser consumable would be long lasting and cost  effective.</p>
<p>While purchasing plasma cutters, it would be good to  make test cuts with many machines and check the quality of each cut.  Here, you must look for a cutter that would offer a tight focused arc.  Another quality checking method is to lift the plasma torch from the  plate during cutting and check how far you can move while maintaining an  arc. Generally when the pilot arc is brought close to the work metal, a  transfer occurs from pilot arc to cutting arc. A plasma cutter that  provides a quick, positive transfer from pilot to cutting arc at large  transfer height would the best choice for getting better support during  cutting.</p>
<p>One of the main things to be noted is the working  visibility of the machine. While you are tracing a pattern, it is  essential to see what you are cutting. A plasma cutting torch which is  smaller and less bulky would be the best to provide working visibility.  Portability is yet another thing to be noted. It is always better to go  for a light weight, portable cutting machine. The most important thing  is ensuring the safety features of the machine. It is highly suggested  that you must buy a machine with nozzle-in-place safety sensor. This  sensor makes sure that the machine won&#8217;t start unless the nozzle is in  place. It is also good to look for a machine that would provide a  pre-flow sequence.</p>

<p>The most common compressors used in refrigeration are  reciprocating, scroll, screw-driven centrifugal. With various  refrigerants chillers used in industry in industrial application,  chilled water or other liquid from the chiller is pumped through  process. Industrial chillers are used for cooling of products and  factory machinery in a wide range of industries.</p>
<p>They are often  used in the plastic industry in plastic processing like injection  molding, blow molding, extruders, laminations, p.P. Films, rigid p.V.C.  Pipe, calendars, chemicals, pharmaceutical process, dyes intermediates,  mineral water soda process, paper converting, coating chill rolls,  plating and anodizing, lubricants/oil cooling, dairy, bakery, food  products, dehumidifier, conditioned air, welding equipment, cement  processing, vacuum systems, x-ray diffraction, analytical equipment,  compressed air and gas cooling.</p>
<p>Chillers are usually small in size (cooling capacity), usually from 1 tons to 100 tons.</p>
<p>Central chillers generally have capacities ranging from ten tons to hundreds or thousands of tons.</p>
<p>Water  chillers can be either water cooled or air-cooled. Water cooled  chillers offer efficiencies better than air cooled is due to heat  rejection at or near the air&#8217;s wet-bulb temperature rather than the  higher, dry-bulb temperature but it is used in conjunction with cooling  tower.</p>
<p>The heart of the chiller is the refrigeration compressor.  This is a pump that uses electrical energy to pump refrigerant around  the system. Depending on the application like size or operating  temperature, a different compressor pumping technology is used. Smaller  chillers use refrigeration compressors like rotary compressors, scroll  compressors, and reciprocating compressors. Larger chillers use  refrigeration compressor like reciprocating compressors, screw  compressors, absorption compressors, and centrifugal compressors.</p>

<p>Milling machines come in various types with a variety of functions  based on certain standard specifications. Some of the most commonly used  machines are the following: column, turret, C-frame, horizontal, bed  type, planer-style, and tracer controlled.</p>
<p>A milling machine is a  tool in the metal industry that has numerous functions. Each machine has  a cutter that operates at a various range of speed so you can form the  required shape. With its adjustable spped feature, each milling machine  can be regulated for a more precise cut. The machine is capable of  handling multiple tasks such as carving, threading, milling, drilling,  and cutting. There are several several types of milling machines, each  with varying functions based on standard criteria. Manufacturers often  name the different machines according to the kind of control, number of  axis present, orientation of the spindle, size of the tool, its purpose,  and source of power. While there are several varieties of milling  machines available today, they essentially serve the same functions but  use different terminologies. Below is the list of seven types of milling  machines.</p>
<p>Column</p>
<p>This is the most common milling machine,  which has 5 basic components, They are the work table, saddle, head,  knee, and over arm. Considered as the simplest machine type, its cutting  device is vertically suspended to allow drilling of metals. This is  typically used when creating car parts because it is small and handy.</p>
<p>Turret</p>
<p>The  turret is also known as the Bridgeport-type and can be repositioned  anytime you want making this machine very functional. Its versatility  makes it more practical since a variety of products can be made in  addition to car parts.</p>
<p>C-frame</p>
<p>Because it is sturdier than a  turret, this type is popular in industrial settings. It comes with a  hydraulic motor, which makes it very powerful.</p>
<p>Horizontal</p>
<p>This  machine runs parallel to the ground. The table from which the object to  be worked on is placed moves sideways while the cutting device goes up  and down.</p>
<p>Bed type</p>
<p>The worktable is located on the bed  itself, instead of being paced on top, its usual position. The knee part  of the machine is omitted to allow movement in a longitudinal  direction.</p>
<p>Planer-style</p>
<p>This machine type is basically the  same as the bed mill. However, the planner-style includes cutters and  heads that allow for a wider range of milling actions.</p>
<p>Tracer controlled</p>
<p>This  type of machine has the ability to reproduce parts based on a master  model. Most of the industrial sectors, especially the automotive  industry, choose this type of machine because it make production and  specialization of machine parts easier. With the vast classifications of  milling machines, you need to choose the one you need according to how  you intend to use it. However if you find it difficult to decide, do not  hesitate to seek the help of a specialist who can help you select the  one that will give you maximum benefits.</p>
