Abstract: Process of grinding and polishing flank surfaces (40) of teeth (50) of toothed wheels (60), comprising the steps of a) providing a grinding device (6), a polishing device (7), a dynamic positioning device (8) and a toothed wheel (60); b) having the grinding device (6) grind the toothed wheel (60); c) removing the toothed wheel (60) from the grinding device (6); d) having the dynamic positioning device (8) bring the flank surface (40) in contact with a polishing body (80) of the polishing device (7) to polish the flank surface; e) having the dynamic positioning device (8) dynamically adjust position and attitude of the toothed wheel (60) relative to the polishing body (80), or having the dynamic positioning device (8) dynamically adjust position and attitude of the polishing body (80) relative to the toothed wheel (60), such that the flank surface is polished by the polishing body. The dynamic positioning device (8) may be a robot.

Abstract: A grinding system is presented that includes a grinding wheel with a coolant channel coupled to a coolant exit. The coolant channel extends through a grinding layer of the grinding wheel. The coolant exit is on an active grinding surface of the grinding wheel. The grinding system also includes a mounting feature configured to couple the grinding wheel to a grinding machine. The grinding system also includes a coolant distribution component configured to receive coolant and provide it through the coolant channel to the coolant exit point.
