"Knurling, cut knurling specifically. Traditional knurling uses two rolls to compress and form the diamond pattern into the material. Cut knurling uses two rolls set at an angle to physically cut the knurling into the material. By threading the blanks onto the fixture I can leave the tool setup (which can be a bit tedious to get it set perfect) and run blank after blank with consistent results."

Knurling on a Lathe vs Knurling on a Tormach 770M CNC Mill. You should definitely be Knurling on a Lathe, but just wanted to show that it’s still possible if you only have a CNC Mill. | Titans of CNC Machining
