High-Performance Surface Grinding – The Influence of Coolant on the Abrasive Process

The availability of newly designed grinding machines with high stiffness. high spindle power and wheel speeds, super-abrasive CBN-grinding wheels, adaptive dressing techniques, coolant delivery, coolant filter, and wheel surface cleaning systems enables application of the high-performance grinding method. This grinding technique using CBN-grinding wheels, can be characterized by high cutting speeds, relatively high material removal rates, and good surface finish. This paper presents the consideration of chip thickness and its influence on the grinding process, due to the grinding parameters, such as cutting speed, depth of cut and work speed. Results obtained in practical investigations concerning the impact of the coolant delivery, on the emerged forces and on the power demand at high peripheral wheel speeds are discussed.
