I can get the lower knurling wheel to track properly but can NOT get the upper wheel to align or track properly. I have wasted a day trying to do this changing the feed, tool is on center, have tried angling the tool. It is a 10 TPI knurl. I am turning the diameter in multiples of .0318. The knurling tips on the 3/4 inch wheel I am using are .100 apart. Need specific helpful instruction to get both of the wheels to track properly. |
Try playing with RPM. If you're 100% sure that centerline is on then it's either speed/feed or pressure. Try leaving a little more material or push a little harder with the knurler(lower your X, not feed). Sometimes you just have to push harder to get both wheels to track together.
