Get the knurls in fast and feed fast .020 is
standard.If you want pretty use straddle knurl holder to eliminate the fllex in your part and again get in and go.On a screw machine we always feed on at about .015 to .022 and of at .025 to .040.This is done from the turret though.I have done it on an engine lathe though.Get ahold of Form Roll and they will give you the books and the
formulas for knurling.I have even knurled splines.Not fun though but posiable |
