Talk:Knurling

adding new section

This article needs some edits. I can do it when agreed. It is mentioned in this article, "On the lathe, knurl cutting is usually accomplished using the same automatic-feed mechanisms that are used to cut screw threads;" Do we cut anything in knurling? Do we get some cutting waste out of this process. If not then let me do the edit. —Preceding unsigned comment added by Altafqadir (talk • contribs) 15:22, 2 June 2009 (UTC)

Re rolled knurls Though the picture shows a knurling tool with two rollers this is only one sort. The other sort has two roller that are clamped on opposite sides of the workpiece. This means the force used is not against the headstock bearings or the cross-slide nut. Furthermore the force used can be much greater. If enough pressure is used a knurl can be made on any diameter of workpiece. When doing this the workpiece and the rollers on the knurling tool should be well lubricated. Where the knurl needed is wider than the knurling tool only a very light force should be applied. The tool is then moved across the workpiece, then the force is increased and so on till the required knurl is achieved. A knurl made like this produces some dust and the result is larger in diameter than the original piece of metal. It would seem to me that most of what happens is the metal is squashed into shape. When the knurl is finished it always looks better if the end of it is chamfered. On a long knurl 45 degrees looks ok but on a short knurl 60 degrees looks better. 81.100.167.66 (talk) 10:47, 28 January 2010 (UTC)

History

Historically, how long have knurls been around? I have a knob from the early 1900's that has been knurled... —Preceding unsigned comment added by Wikimvn1 (talk • contribs) 17:32, 7 October 2010 (UTC)
