Laser processing of high performance grinding wheels

High performance grinding is a process that produces engineering components with a desired surface roughness. The grinding efficiency of vitrified grinding wheels deteriorates as the sharp cutting edges become blunt due to the formation of wear flats. Dressing is essentially a sharpening operation designed to generate a specific topography on the working surface of the grinding wheel.

In Grinding, Coolant Application Matters

Coherent-jet nozzles give better grinding performance because they concentrate the coolant into the grinding zone, allowing the pores of the wheel to be fully filled, and thereby minimize the applied flow rate. A dispersed jet pumps air and coolant into the grinding wheel, displacing some of the fluid with air.
