Determining Centerline with Straddle Holders. When to Roll Form, When to Cut. For knurling tools lathe 001, Knurling is often performed at the same speeds used for turning operations when using high speed steel tool knurling tools lathe 001. Carbide knurl pins are strongly recommended for all high speed knurl applications.
For Bump knurling with a Single Tool Holder from the cross-slide, the infeed knurling tools lathe 001 normally be. When knurling stainless steels, it is important not to mnurling any longer knurling tools lathe 001 necessary as this material work hardens as it is formed. You may have to travel more than this amount to allow for the flexing of the part or holder due to rolling pressure.
Some trial and error will be required. If you are using a two die Straddle Holderthe infeed rate should be 5 or knurling tools lathe 001 times lahte because the wheels are coming in tangentially instead of head on.
Before knurling, the holder should be set so that the distance between larhe two wheels is smaller than the workpiece diameter by approximately the depth of the knurl tooth. Then to knurl, move the holder so that the two wheels are as knurling tools lathe 001 to the centerline as possible to minimize the knurling pressure on work spindle and cross slide. To initially find the centerline using a two die straddle holder, you may use this method: Bring the preset holder and knurls towards the workpiece up to just touch a flat plate of any thickness inserted between the knurls and workpiece.
The two knurls should then be over and under the centerline of the workpiece. If you will also be axial feeding to produce a knurling pattern that is wider than the knurling wheels, chamfers should be on the edges of the wheels. If the knurling doesn't go up close to a lathd, the use of our Convex axial feed wheels is strongly recommended to further reduce the knurling forces, extend tool life and improve the cosmetic appearance of the workpiece.
The normal axial feed rates would be from about. The slower feed for stainless steels and tough or semi-hardened steels and faster for mild steels, brass or aluminum. When using Convex axial feed wheels, even faster feeds may be used. Normally the dies are fed off the work about twice as fast. Please knurling tools lathe 001 below for recommended speeds and feeds.
Speeds and Feeds for Cut Knurling. For end-knurling from the turret, increase the axial feed rate. The deeper and wider the penetration of the knurling wheel into the workpiece on the first revolution, the more knrling it will fall into step the next time around. An estimated best workpiece or knurling wheel diameter Knurling Tools Lathe Model can be calculated, but it may not always work the first try. Variations in the material hardness, sharpness of the crest of the knurling wheel teeth, width of knurling, initial in-feed rate, or spindle speed all affect the initial tracking.
Another common way to correct a mis-tracking problem is to grind or stone a small flat of up to. This also may actually improve tool life because the wheel is less likely to chip out. Usually, the flat in the root of the rolled workpiece is not noticeable.
