Knurling




Knurling is a process where the surface of part of a machined job/machined job is made rough using a knurling tool.This rough surface of the machined component makes the of the person holding it to have better grip while working with it.Sometimes it is just for aesthetics.Sometimes it is also used to have better bonding with the other material that will be coated over the knurled machined component.

The knurling operation is started by determining the location and length of the knurl, and then setting the machine for knurling. A slow speed is needed with a medium feed. Commonly, the speed is set to 60 to 80 RPM, while the feed is best from 0.015 to 0.030 inch per revolution of the spindle. 

The knurling tool must be set in the tool post with the axis of the knurling head at center height and the face of the knurls parallel with the work surface. Check that the rollers move freely and are in good cutting condition; then oil the knurling tool cutting wheels where they contact the workpiece. Bring the cutting wheels (rollers) up to the surface of the work with approximately 1/2 of the face of the roller in contact with the work.
