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 an annular surface with a circular arc profile in axial cross section is used to first generate a surface on a cutting blade (22) by grinding with the annular surface during a first orientation in space between the grinding wheel (28) and the cutting blade (22) by means of at least one first relative translational movement between the same, and subsequently at least one part of the generated surface is reground with the annular surface during a second orientation in space between the grinding wheel (28) and the cutting blade (22) by means of at least one second relative translational movement between the same. The grinding wheel (28) is a diamond cup-type grinding wheel. One part (34') of the working area (34) is located in a face area and another part (34'') is located in a cylinder area of the grinding wheel (28). The one part (34') is used for rough grinding and the other part (34'') is used for finish grinding of the surface to be generated on the cutting blade (22). The grinding wheel (28) has the same abrasive coating for the entire working area (34). Thus roughing and finishing are performed 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 blade (22) is selected by adjusting the cutting blade (22) in relation to the grinding wheel (28). The method enables planar and/or convex and concave surfaces to be generated on a cutting blade.
