Improved coolant supply through slotted grinding wheel

A suitable coolant supply in grinding is mandatory to comply with the demanded workpiece quality, to avoid thermal damage and to reduce tool wear. In this paper, the development of a slotted grinding wheel with optimized coolant supply is described. This simple but efficient approach was based on previous investigations on external and internal supply methods, which are briefly described. The performance of the slotted grinding wheel in comparison to two other grinding wheels, applying the same coolant nozzle for each, revealed significant improvements in the cooling efficiency.
