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

Abstract

A grinding wheel ( ) 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 ( ) by grinding with the annular surface during a first orientation in space between the grinding wheel ( ) and the cutting blade ( ) 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 ( ) and the cutting blade ( ) by means of at least one second relative translational movement between the same. The grinding wheel ( ) is a diamond cup-type grinding wheel. One part ( ′) of the working area ( ) is located in a face area and another part ( ″) is located in a cylinder area of the grinding wheel ( ). The one part ( ′) is used for rough grinding and the other part ( ″) is used for finish grinding of the surface to be generated on the cutting blade ( ). The grinding wheel ( ) has the same abrasive coating for the entire working area ( ). Thus roughing and finishing are performed using areas of the grinding wheel ( ) that have the same specifications but different grinding parameters. Preferably, spatial orientation between the grinding wheel ( ) and the cutting blade ( ) is selected by adjusting the cutting blade ( ) in relation to the grinding wheel ( ). The method enables planar and/or convex and concave surfaces to be generated on a cutting blade.
