Abstract (en)

[origin: WO2022128630A1] In a method for machining workpieces in a tooth-grinding machine having a grinding tool (320) which has ceramically bonded abrasive particles consisting of a superabrasive material, the grinding tool is first dressed. Then, the dressed grinding tool is conditioned such that a desired wear state of the grinding tool is produced. Then, pre-toothed workpieces are machined using the dressed and conditioned grinding tool. The conditioning prevents an undesired grinding-in behaviour of the grinding tool in which thermal damage to the edge zone of the workpiece can occur. Conditioning is carried out with conditioning kinematics which differ from machining kinematics and can correspond to dressing kinematics. A conditioning tool (416; 425) having a basic shape which differs from the basic shape of the workpieces is used for conditioning.
