摘要： The invention relates to a grinding disc (12) and a method for grinding bar blades for producing crown teeth. To grind a bar blade (1) of this type in a economic manner, the grinding disc (12) has a conical grinding surface (Pp), which broadens from a small diameter (d1) to a large diameter (d2), a cylindrical grinding surface (Ps), which adjoins the conical grinding surface (Pp) and a toroidal grinding surface (G), which adjoins the cylindrical grinding surface (Ps). This configuration of the grinding disc (12) allows the profile grinding (rough-working) and subsequently the production grinding (facing) of the surfaces of the bar blade (1), without having to unclamp the latter. To achieve this, the grinding disc (12) rotates about a fixed axis (S) and the bar blade (1) to be ground is guided along the grinding disc (12) and set at corresponding angles to the latter.

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 between the grinding wheel (28) and the cutting knife (22) by means of at least one first translational relative movement between the same, and subsequently by grinding at least one part of the surface produced with the ring surface oriented at a second point in space between the grinding wheel (28) and the cutting knife (22) by means of at least one second translational relative movement between the same. The grinding wheel (28) is a diamond cupped 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). One part (34') is used for roughing down and the other is used to smooth-polish the surface that is to be created on the cutting knife (22). The grinding wheel (28) 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.
