One of the more common alloys is Ti 6AL-4V. It is generally machined at a hardness ranging from approx. 28 to 37 Rc. </p> <p>One the characteristics that makes titanium difficult to tap is its tremendous elastic memory. When tapping, the material closes tightly around the cutting tool, generating friction and heat, resulting in increased wear of the cutting edges. This material also easily work hardens.</p> <p>To successfully tap titanium, a tap specifically designed with additional clearance to overcome the extreme elastic memory of the material is recommended. </p> <p>Tap clearances would include extra back taper of the threads from the front to the back of the thread section, full radial clearance in the threads across the tap lands, and additional relief in the tap chamfer area.</p> <p>All of these features are used to reduce friction and heat. In some cases, larger H limits might be required to overcome the shrinkage. </p> <p>Premium grade materials are also used for heat and wear resistance. Obviously we offer these in our standard product lines.</p> <p>Lubrication and proper pre-tapped hole size are vital to success. A compatible tapping fluid should be used that provides plenty of lubrication to reduce friction.</p> <p>The drill should be selected to produce the largest hole size that is allowed by the thread class callout (2B or 3B).</p> Due to the additional clearances required on these tools, positive feeding of the tap is highly recommended.<br /><br /><a href="http://carbideinserts.blogspot.com/2007/11/machining-titanium-roughing-finishing.html">Machining Titanium Tips</a><br /><br /><a href="http://carbideinserts.blogspot.com/2008/02/inserts-for-difficult-materials.html">Inserts for Machining Titanium</a>Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-75592305362725516302009-01-16T18:03:00.000-08:002009-01-16T18:03:00.765-08:00Machining Aluminum<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/eCr710Np1ws&hl=en&fs=1"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed src="http://www.youtube.com/v/eCr710Np1ws&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object><br /><h1><span style="font-size:85%;">V8 Engine Block Machining From Solid Aluminum</span></h1><span style="font-size:100%;">Aluminum is Inexpensive, Lightweight and is Formable at Cold Temperatures<br /><br /></span>Aluminum is one of the most common materials used in manufacturing strong, lightweight parts.

Actually, the tap is often the victim of a badly drilled hole. You can't produce a great thread out of a bad hole! Following are some issues and possible resolutions.<br /> <br /> 1. A dull drill will create a very rough torn hole. Expect poor or incomplete threads.<br /> <br />2. A reground drill must be perfectly concentric. The cutting lips must be of equal length and be ground to the same angles. Failure to create a concentric point will cause the drill to cut on one side more than the other and a crooked, bent hole will result making an attempt to tap that hole very difficult. This can also produce an oval egg shaped hole.<br /> <br />3. Castings sometimes have a tapered hole so the part will release easily. Threading requires straight walls and tapered walls are impossible to thread correctly. </p> <p>4. Undersized holes are difficult or impossible to thread.<br /> <br />5. Holes that have had the surface work hardened by too high a temperature in the drilling process can become too hard to thread effectively.<br /> <br /> 6. Materials that shrink or close-in after drilling are undersized for tapping.<br /> <br /> 7. Holes too near welding or flame cut areas can become hardened and difficult to thread.<br />Bottom line, consider good hole quality as essential in producing quality holes and if you are having difficulty, dont forget to investigate the drilling process in addition to the tap.</p>Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-55556541678365453712009-01-04T17:39:00.000-08:002009-01-04T17:53:16.049-08:00Selecting Thread Mill Diameters<center><object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/9MpryUbTn_E&hl=en&fs=1"><param name="allowFullScreen" value="true"><param name="allowscriptaccess" value="always"><embed src="http://www.youtube.com/v/9MpryUbTn_E&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object></center><br /><br />Tips for Selecting <a href="http://www.threadmillsusa.com/">Thread Mill</a> Diameters<br /><br />When producing internal threads, selecting the right thread mill diameter insures it will operate efficiently. <p>Thread mills are usually offered in several cutting diameters for a given threads per inch. Smaller diameters are used for small thread sizes, such as 3/8-16 NC. </p> <p>A larger tool diameter could be used for producing a 3/4-16 NF. However, the smaller thread mill could be used to produce the larger 3/4-16 as well.</p> <p>Generally, for coarser pitches (coarser than 14 TPI), selecting a cutting diameter no larger than 70% of the nominal thread size to be produced is recommended. </p> <p>For finer pitches, the thread mill can be as large as 75% of the nominal diameter. Although the tool has radial clearances similar to end mills, if the tool diameter is too close to the thread diameter, the tool may rub, producing more heat that could result in excessive wear. </p> <p>This rubbing may also distort the thread form affecting the thread angle.</p> <p>The question is, should the largest <a href="http://www.threadmillsusa.com/">thread mill</a> that will fit the hole be used? The answer is, not necessarily! </p> <p>For the greatest efficiency, smaller mills will remove more cubic inch of metal than a larger one, resulting in greater productivity. </p> <p>There will be more clearance for the tool and more space for coolant and chips. </p> <p> However, to optimize the tool, it will be rotating much faster, which may exceed the capability of the machine. </p> <p>Also, the thread length on the tool may be too short for the thread depth required. </p> <p>On the other hand, the larger diameter thread mill will minimize deflection, particularly on coarse thread series, but is more prone to rubbing and chip congestion.<br /> </p>Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-29878512645939772422008-12-02T08:14:00.000-08:002008-12-03T19:54:20.267-08:00Tips for Machining Stainless Steel<center><embed id="VideoPlayback" src="http://video.google.com/googleplayer.swf?docid=-5175987274002672602&hl=un&fs=true" style="width: 400px; height: 326px;" allowfullscreen="true" allowscriptaccess="always" type="application/x-shockwave-flash"></embed></center><div style="text-align: center;"><span style="font-size:78%;"><span style="font-weight: bold;">Video of <a href="http://www.tetoncreekcnc.com/">Teton Creek Mfg</a> turning Stainless Steel</span></span><br /></div><br />Here are a list of tips for <a href="http://carbideinserts.blogspot.com/2008/11/valenite-carbide-inserts-for-stainless.html">machining stainless steel</a>:<br /><br /><span style="font-weight: bold;">1. Use a tool that has higher thermal-conductivity</span><br />Low thermal-conductivity of stainless steels accelerates tool wear resulting from a decline in hardness of the cutting edge of an insert, this is due to heat piling up. It is better to use a tool that has higher thermal conductivity and with enough coolant.<br /><br /><span style="font-weight: bold;">2. Sharper cutting edge-line</span><br />It is necessary to utilize larger rake-angles and wider chip-breaker lands to reduce cutting-load pressue and prevent build-up on the edge. This will help provide better chip control to an operator.<br /><br /><span style="font-weight: bold;">3. Optimal cutting condition</span><br />Inappropriate machining conditions like extremely low or high speeds or low feeds can cause poor tool life due to work hardening of work pieces.<br /><br /><span style="font-weight: bold;">4. Choose an appropriate tools</span><br />Tools for stainless steel should have good toughness attributes, enough strength on their edge line (cutting edge) & a higher film adhesion.<br /><br /><a href="http://www.korloy.com/eng/e_mainF.html">Korloy</a> offers three grades turning stainless steel:<br /><br /><a href="http://www.pgstools.com/servlet/Categories?$catalog.Oem=Korloy&$catalog.keyword=NC9020">For high speed turning of stainless steel - NC9020</a><br /><br /><a href="http://www.pgstools.com/servlet/Categories?$catalog.Oem=Korloy&$catalog.keyword=PC9030">For medium to low speed turning of stainless steel - PC9030</a><br /><br /><a href="http://www.pgstools.com/servlet/Categories?$catalog.Oem=Korloy&$catalog.keyword=PC9530">For medium to low speed milling of stainless steel - PC9530</a><br /><br />For Korloy <a href="http://carbideinserts.blogspot.com/2008/12/tips-for-machining-staineless-steel.html">carbide inserts for stainless steel</a>, please visit pgsTools.com to order online.Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-15877753875768724892008-11-17T08:59:00.000-08:002008-11-17T09:28:33.756-08:00Hardware for Toolholders and Boring Bars<div style="text-align: center; font-weight: bold;">Find Spare Parts for Tool Holders and Boring Bars<br /><br /></div>Lose a screw, lock pin, or clamp for your boring bar or toolholder?

The new cutting technologies are the ValProTM VP8515 and VP8525 MT-CVD series of inserts. Both are being developed to augment the existing VP8535 grade and provide a complete range of turning capabilities for <span style="font-weight: bold;">304 and 316 stainless steels, Inconel and heat resistant alloys</span>. The VP8515 is for finishing operations and the VP8525 is used for general duty semi-roughing/finishing. The existing <a href="http://www.pgstools.com/servlet/the-14514/CNMG%2C433M2%2CVP8535%2CVALPRO%2CInsert%2CCNMG433M2-VP8535/Detail">VP8535</a> is for heavy metal removal tasks and roughing operations. </span> </p><p><span style=";font-family:Verdana;font-size:85%;" > The VP8515 grade is set for high cutting speed (>200 m/min) at typical finishing</span> </p><p><span style=";font-family:Verdana;font-size:85%;" >cut depths and has broad applicability with F5, M4, M6, M8, PM2, PM5 geometries. This grade is ideal for continuous turning of austenitic and duplex stainless steels at higher speeds providing reliable and predictable performance, with extended insert service life. Inserts using VP8515 grade have a thin yellow TiN outer coating for easy visual wear identification, an Al2O3 layer for thermal protection, a fine MT-CVD TiCN coating that helps to prevent flaking and reduces flank wear. Also incorporated in the tooling is a gradient area for added surface toughness, and a hard substrate offering greater resistance to wear and plastic deformation.</span> </p><p><span style=";font-family:Verdana;font-size:85%;" > The TiCN/Al2O3/TiN coating is formulated specifically for turning of <a href="http://en.wikipedia.org/wiki/Stainless_steel">stainless steels</a> and to resist sticking, notch wear and edge build-up, for enhanced hardness when hot.</span> </p><p><span style=";font-family:Verdana;font-size:85%;" > The VP8525’s performance characteristics deliver high cutting speeds (>150 m/min) with mid- to large cutting depths...inserts have M4, M6, M8, R9, PM4, PM5 geometries to cover a myriad of cutting parameters. This grade is a basic choice for general duty M-class turning—continuous or intermittent cutting of austenitic and duplex stainless steels. These tools reduce the risk of <a href="http://www.ndt-ed.org/EducationResources/CommunityCollege/Materials/Structure/deformation.htm">plastic deformation</a> and, like the VP8515, provide reliable performance and extended tool life. The VP8525 grade has similar coating technologies, layering and substrate construction as the finishing grade, including the TiCN/Al2O3/TiN coating for the efficient turning of stainless steels.</span> </p>--------------------------------<br /><br /><span style="font-size:100%;">Get carbide inserts or cutting tools for stainless steel machining at <a href="http://www.pgstools.com/">www.pgstools.com</a>.

The procedure of cutting is executed through a cutting tool which is applied either parallel or at right angle to the axis, of work piece. The tool may also be fitted at an angle relative to the work piece axis for the machining angles and tapers. The work piece may be of any cross section, but the machine surface should be straight and tapered.</p><p>There are various shapes available in CNC like pointed, simple, radius with profile added with threaded surface, curve and fillet. CNC machining is more economical than the CNC milling for producing the actual form through CNC turning. The material used for CNC turning possesses various qualities like material of work piece should be firm and can be of solid plastics. For the short running procedure of the mill, arrangements or alternative machine should be kept. CNC turning reduces the cost by minimizing the design elements.<br /><br />CNC turning procedure is done through applying pressure on the work piece or the weaker material to form the flexible shapes of the material. Sometimes through CNC, the cut surface is formed by applying the helical feed as it results in rotation. The cutting procedure through which the work piece is eliminated from a material block by the help of the rotation of the tool is known as CNC milling. The work piece can rotate in perpendicular or circular way to produce different shapes and sizes. The cutting tool generally rotates in the CNC milling at an axis in a perpendicular form on the podium to generate various structures.<br /><br />Variety of shapes that can be formed through CNC milling is 3D or 2D and some compound structured material. CNC milling for short procedure is also very economical. It is utilized to make different parts of engine, multifaceted mechanisms, enclosures and mold and custom tooling.<br /><br />Thus, is a very effective procedure to make various machine parts of various shapes which is very significant for running the machine.</p><div style="text-align: center;"><span style="font-size:100%;">Get carbide inserts or cutting tools for your cnc machines at <a href="http://www.pgstools.com/">www.pgstools.com</a>.

Such cutters are also often referred to by the set-phrase name of <b>single-point cutting tool</b>. The <a href="http://en.wikipedia.org/wiki/Cutting_edge" title="Cutting edge">cutting edge</a> is ground to suit a particular machining operation and may be resharpened or reshaped as needed. The ground tool bit is held rigidly by a tool holder while it is cutting.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://upload.wikimedia.org/wikipedia/commons/thumb/0/0e/Tool_Bit_Geometry.JPG/300px-Tool_Bit_Geometry.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 200px;" src="http://upload.wikimedia.org/wikipedia/commons/thumb/0/0e/Tool_Bit_Geometry.JPG/300px-Tool_Bit_Geometry.JPG" alt="" border="0" /></a>Back Rake is to help control the direction of the chip, which naturally curves into the work due to the difference in length from the outer and inner parts of the cut. It also helps counteract the pressure against the tool from the work by pulling the tool into the work. <p>Side Rake along with back rake controls the chip flow and partly counteracts the resistance of the work to the movement of the cutter and can be optimized to suit the particular material being cut. Brass for example requires a back and side rake of 0 degrees while aluminum uses a back rake of 35 degrees and a side rake of 15 degrees.</p> <p>Nose Radius makes the finish of the cut smoother as it can overlap the previous cut and eliminate the peaks and valleys that a pointed tool produces. Having a radius also strengthens the tip, a sharp point being quite fragile.</p> <p>All the other angles are for clearance in order that no part of the tool besides the actual cutting edge can touch the work. The front clearance angle is usually 8 degrees while the side clearance angle is 10-15 degrees and partly depends on the rate of feed expected.</p> <p>Minimum angles which do the job required are advisable because the tool gets weaker as the edge gets keener due to the lessening support behind the edge and the reduced ability to absorb heat generated by cutting.</p> <p>The Rake angles on the top of the tool need not be precise in order to cut but to cut efficiently there will be an optimum angle for back and side rake.</p><span style="font-size:78%;">Ref: http://en.wikipedia.org/wiki/Tool_bit<br /><br /></span>Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-25046454074715362102008-08-15T08:58:00.000-07:002008-08-15T09:00:34.417-07:00All About Cermet Inserts<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.pgstools.com/catalog/TTCCMTFG.JPG"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 132px; height: 115px;" src="http://www.pgstools.com/catalog/TTCCMTFG.JPG" alt="" border="0" /></a><a href="http://www.pgstools.com/servlet/the-Cermet-Inserts/Categories">Cermet inserts</a> can't quite replace the coated carbide inserts in heavy roughing operations with interrupted cuts, but in semifinishing and finishing cermet inserts outperform carbide. They permit a higher surface speed while maintaining an acceptable surface finish with good tolerance holding property and increased tool life. Because the cermet surface is slick it presents less friction to the chip flowing over the cutting edge which decreases the possibility of build-up when machining high alloy steels and cold-formed, low-carbon steels. <a href="http://www.pgstools.com/servlet/the-Cermet-Inserts/Categories">Cermet inserts</a> are available from several suppliers with a wide selection of pressed-in chipbreaker configurations or ground-in chipbreakers. <p> The <a href="http://www.pgstools.com/servlet/the-Cermet-Inserts/Categories">cermet inserts</a> work at surface speeds from 100 to 1000 sfpm. On multi-spindle-automatics, positive inserts made of cermets avoid build-up encountered when running carbide inserts with low surface speeds. Also cratering is reduced due to the low heat transfer properties of the cermet material.</p> <p> The recommended cutting speed for turning unalloyed steel with approximately 200 HB is 250 to 800 sfpm with 0.002" to 0.015" fpr and depth of cut of 0.004" to 0.150". Alloy steels up to hardness of 300 HB will have satisfactory tool life when machined between 200 and 600 sfpm with the depth of cut and feedrate mentioned above.</p> <p> Face milling with cermet inserts can be achieved with the same cutting speeds as turning with chip loads per insert from 0.002" to 0.12". Milling is performed dry, while turning can be dry or with coolants.</p> <p> Up to the present, cermets are widely used in Japan with good results in reducing machining costs. They deserve a greater consideration for material removal in the United States.</p> <!-- google_ad_section_end (name=s2) --><span style="font-size:78%;">COPYRIGHT 1989 Gardner Publications, Inc.</span>Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-10858863316584989302008-06-03T08:55:00.000-07:002008-06-04T08:52:14.458-07:00Precision Cast Iron Machining<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.dreng.co.uk/images/cbn/photos/80/bs1.jpg"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 192px; height: 284px;" src="http://www.dreng.co.uk/images/cbn/photos/80/bs1.jpg" alt="" border="0" /></a><br /><span style=";font-family:Verdana;font-size:100%;" >Whether you’re making brake discs and flywheels in grey cast iron, or crank shafts and wheel hubs in nodular cast iron, there is always a successful solution.<br /><br />Over the years there have been a number of CBN grades made available for <a href="http://carbideinserts.blogspot.com/2007/10/machining-cast-iron-with-cbn-inserts.html">machining cast iron with CBN</a>.

First, a mold shop can replace several operations with one operation. Instead of machining, hardening and remachining, the use of ceramic inserts enables a shop to harden the steel first and then machine the part in the hardened form. This reduces manufacturing time and improves job tracking by reducing the number of times that you must set up and move a component through various manufacturing phases. Furthermore, roughing a hardened part with ceramic inserts also can eliminate expensive and time-consuming EDM operations, as well as the need to make one or more electrodes.</p> <p>Second, <a style="font-weight: bold;" href="http://www.pgstools.com/servlet/the-Ceramic-Inserts/Categories">ceramic inserts</a> are capable of <a href="http://carbideinserts.blogspot.com/2008/02/hardturning-with-cbn-finish-machining.html">machining hardened steel</a> at much higher speeds than conventional <a href="http://www.pgstools.com">carbide cutting tools</a>. Combine the higher operating speed with the proper feedrate and a healthy step-over and the shop can achieve some impressive metal removal rates. Another key factor in increased production rates when hard milling is the cutter density. Every additional tooth in a cutter increases the cross feedrate. Higher speed and more feed add up to lower cycle times and money saved.</p> <p>Third, many times the surface finish achieved by rough milling with ceramics leaves less work for a finish milling operation, and reduces finishing and polishing time. Milling at relatively light feedrates in hardened steel with carbide usually leaves a good finish, but many times with ceramic inserts the rough finish is even better than the required finish. In some cases, additional milling, grinding and polishing can be eliminated, saving several hours of manufacturing.</p>Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-74525553486232495782008-05-14T08:39:00.000-07:002008-05-14T08:49:20.447-07:00Cylinder Boring with CBN or PCD Inserts<center><object height="355" width="425"><param name="movie" value="http://www.youtube.com/v/a2tXtJ2cARE&hl=en"><param name="wmode" value="transparent"><embed src="http://www.youtube.com/v/a2tXtJ2cARE&hl=en" type="application/x-shockwave-flash" wmode="transparent" height="355" width="425"></embed></object></center><br /><p><span style=";font-family:Arial;font-size:85%;" >Boring out cylinders to accept oversized pistons or sleeves has long been a common practice in the engine rebuilding business.

The latter is much more expensive. Thus, comparison of tool wear becomes most important.<br /><br />The two materials show marked performance differences in both size and surface finish in roughing, interrupted, and finishing cuts. In comparison to grinding, however, both materials will achieve much higher metal removal rates.<br /><br />CBN will out-perform ceramic in interrupted cuts. With depth-of-cut of 0.060 inch to 0.120 inch and a speed of 350 sfpm with 0.010 to 0.020 inch feed per revolution, ceramic often will fail when entering the interruption. With CBN, a tool life up to 20 minutes can be achieved with a half-inch round insert, under the above conditions. Flank wear in interrupted cuts is more irregular than in continuous cuts and can shorten tool life. <a style="font-weight: bold;" href="http://www.pgstools.com/servlet/the-CBN-Inserts-cln-RNMN/Categories">Solid CBN inserts</a> have greater flank wear resistance and are superior to ceramics for roughing, especially where the turning has interrupted cuts.<br /><br />For finishing cuts where small depths of cut and low feed rates are required to achieve superior surface finishes, <a href="http://www.pgstools.com/servlet/the-CBN-Inserts/Categories"><span style="font-weight: bold;">CBN inserts</span></a> cannot equal the tool life of <a href="http://www.pgstools.com/servlet/the-Ceramic-Inserts/Categories"><span style="font-weight: bold;">ceramic inserts</span></a>. Under these conditions, the ceramic insert has less than half the flank wear of CBN after 30 minutes cutting time.<br /><br />Considering that CBN is ten times more costly than ceramic for the same size and geometry insert, CBN economically can be justified only for machining heat treated steel in those situations where ceramic fails completely or breaks down before finishing the workpiece.<br /><br /><span style="font-size:78%;">excerpted from gardner article</span>Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-2960846354930754642008-04-13T19:06:00.000-07:002008-04-13T19:25:00.629-07:00A Post About Absolutely NothingOk, so in the title it says that on from time to time there would be an occasional rant about nothing. I haven't faithfully held my end of the bargain on that one. Therefore folks, here you go, a rant about nothing.<br /><br />Over the weekend at our church, I had the pleasure of playing my acoustic guitar with some very talented musicians, in front of a few thousand people. I tell you what, in my life, this was up there with being one of the more difficult thing I've ever had to do. My attempts at public speaking, while enjoyable would be number one, but after time that becomes less nerve inducing. But doing something that has always been a hobby, in front of a large group of people was enough to put the sweat glands into overload. On more than one occasion it seemed like they had turned up the heat, then I realized, oh, its just me. <br /><br />I am grateful that I was given the opportunity to share the talent that I have been blessed with. I was feeling pretty good about my guitar playing skills, until I came across the following video, shown below. I know now that I still have a long way to go. Hope you enjoyed the rant, now enjoy a truly talented musician.<br /><br />Regards.<br /><br /><center><object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/JsD6uEZsIsU&hl=en"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/JsD6uEZsIsU&hl=en" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object></center>Anonymoushttp://www.blogger.com/profile/05238978542872041315noreply@blogger.com0tag:blogger.com,1999:blog-4433839238670235879.post-7489803303041200372008-04-13T17:37:00.000-07:002008-04-13T17:48:20.623-07:00An Introduction to Knurling Tools<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.technologystudent.com/images2/knurl3.gif"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 291px; height: 155px;" src="http://www.technologystudent.com/images2/knurl3.gif" alt="" border="0" /></a><br /><div style="text-align: center;"><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://www.technologystudent.com/images2/knurl4.gif"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 242px; height: 121px;" src="http://www.technologystudent.com/images2/knurl4.gif" alt="" border="0" /></a><br /><span style="font-size:78%;">Thanks to </span><span style="font-size:78%;">V.

The stamped ruts might also act as hand grips for the user or superior grip for rubber and the plastic covers. The knurling tool itself comprises of various rotary cutters that are held against the metal shaft as it turns on the metal lathe at a moderately slow speed (500 rpm on average). Turning is a technique by which cylindrical pieces of metal lathe or wood are spun in place by a variable-speed electric motor. As the piece spins, a variety of cutting tools could be placed against it to take away fabric or cut shapes. A knurling tool falls among an engraver and an embosser.<br /><br />There are usually three shapes created by most knurling tools - straight lines, slanting lines and a diamond pattern. <a href="http://www.pgstools.com/servlet/the-6643/%2319-Adjustable-Knurling-Holder/Detail">Knurling tools</a> do come in different range of sizes and amazing designs, depending on the basis of the piece. The diamond pattern is mainly familiar with hand grips as it generates the most grips among a user's hand and the shaft. Diagonal and straight knurls are usually used to give additional traction to an outside handle or other connective piece. In order to generate a knurl pattern, the metal lathe should hold the metal piece entirely straight - a condition machinist call 'true'. As the lathe begins to roll, a particular holder for the knurling tool is attached to the perform table.<br /><br />The <a href="http://www.pgstools.com/servlet/the-6642/%2319-Adjustable-Knurling-Holder/Detail">knurling tool</a> itself is fixed into the lathe and cautiously directed to the turning piece with a tiny crank. Since knurling is extremely a rough process, the machinist must use a liberal supply of machine oil on the rotating shaft. A knurling tool hardly ever makes a complete imprint the first time it is pressed against the shaft. Machinists usually make several passes with the knurling tool, allowing the individual cutters to make small bites into the metal. A knurling tool is best compatible for softer metals such as aluminum or normal grade steel. Hard metals such as titanium would most probable ruin the tool before any embossing could take place.<br /><br /><span style="font-size:78%;">Article Source: http://www.articlesbase.com/sales-articles/an-introduction-to-knurling-tool-226481.html<br /><br />About the Author:<br />John Russel is a Copywriter of Lathe chucks.
