Abstract (en)

Grinding tool (100) comprising a grinding portion (110), wherein the grinding portion (110) is shaped according to a predetermined shape (120) and is substantially rotationally symmetric with respect to a symmetry axis. The grinding tool (100) is manufactured according to a dressing process, the dressing process comprising the steps of (a) rotating the grinding tool (100) about the symmetry axis with a cutting speed; and (b) putting cutting means (300) in engagement with the grinding portion (110) and moving the cuttings means (300) along a given path thereby cutting and shaping the grinding portion (110). The cutting means traverses across the grinding portion (110) with a feed rate. The grinding portion (110) is made of a first material, wherein the first material comprises metal-bonded cubic crystalline boron nitride grains, and the cutting means (300) is made of a second material, wherein the second material comprising at least a cubic crystalline boron nitride material and/ordiamond.
