METHOD FOR GRINDING AT LEAST ONE SURFACE ON A CUTTING KNIFE USED IN MACHINING, USE OF SAID METHOD AND GRINDING WHEEL USED TO CARRY OUT SAID METHOD

摘要

A grinding wheel (28) that rotates around an axis and that has a working area consisting of a ring area with a circular arc profile is used to create a surface by initial grinding with the ring surface oriented at a first point in space on the cutting knife (22) by means of at least one first translational relative movement.Subsequently one part of the surface produced with the ring surface oriented at a second point in space is grinded by means of at least one second translational relative movement. The grinding wheel (28) is a diamond cupped grinding wheel and has the same abrasive covering for the entire working area (34). Roughing down and smooth-polishing occur using areas of the grinding wheel (28) that have the same specifications but different grinding parameters. Preferably, spatial orientation between the grinding wheel (28) and the cutting knife (22) is selected by adjusting the cutting knife (22) in relation to the grinding wheel (28). The inventive method enables planar and/or convex and concave surfaces to be created on a cutting knife.
