The R8ooH workpiece does not produce frictional motion, does not scratch the surface, drives the slide rail to move, making-pushing chamfering easier and more labor-saving, and drives Ithe slide rail to apply force, resulting in a more flat and uniform chamfered surface.
R9ooH guide rail widened and lengthened, overall heat treatment, fine grinding plate surface, plated with hard chrome, more durable and wear.
