Grinding and extruding are the ways of processing the center hole of guide pin, and these processes could be machined on a lathe, drill press or special machine.
The guide pin is assembled on the lathe, and rotated with main shaft. Coated with lapping compound on the guide pin surface, and then cased with grinding tool, the guide pin will process
reciprocating motion in the axial direction. The diameter of the grinding bushing could be regulated by adjusting the screw and the nut on the grinding tool, which could control the grinding degree for the guide pin
