GRINDING OF HARDENED STEELS USING OPTIMIZED COOLING

Grinding the final machining process of a workpiece requires large amounts of cutting fluids for the lubrication, cooling and removal of chips. These fluids are highly aggressive to the environment. With the technological advances of recent years, the worldwide trend is to produce increasingly s...
