I have very little background in knurling and am struggling to get a good looking knurl on a job I am currently setting up. I am working on a Euro Tech Trofeo 481, Using a 16TPI male diamond single wheel bump knurling tool. Before knurling, I am Turning my blank diameter (material is 303 stainless) to .437 with the hope of achieving a diameter which will allow for an even number of teeth per inch on the part... My goal end diameters .450 +/-.01. To knurl, I am feeding straight onto the part at F:.007 to a depth of .4088 ( 45% of the TPI pitch of my knurl past the turned pre knurl diameter) and allowing the tool to dwell for 1 second at max depth before rapiding directly off the part. Despite following every suggestion I can find online, I am still unable to get a consistent knurl. I have tried adjusting feed in speeds and depths however no matter what I do I cant seem to avoid bad double tracking marks on the part. Any type of suggestions or methods which have proven successful would be greatly appreciated. Thanks.
