TW202222471A - Cutter adjustment mechanism of processing machine - Google Patents

Abstract

A cutter adjustment mechanism of processing machine includes a base, an adjustment screw, a cutter holder and a driven screw. The adjustment screw is rotatable mounted and visible on the base. The driven screw is mounted and visible on the cutter holder. The driven screw on the cutter holder is thread-jointed to the adjustment screw, as a result, rotating the adjustment screw can make the driven screw move the cutter holder. The movement of the cutter holder relative to the base along a vertical direction is adjustable to move a cutter mounted on the cutter holder to a predetermined position. Furthermore, the adjustment screw and/or the driven screw can be replaced according to different requirements such that the cutter adjustment mechanism is applicable to different processing machines.
