A cool approach to a grindingly hot issue

摘要

A major element in the manufacturing process of jet engine compressor blades centers on the grinding technology applied. Holroyd's solution to safe grinding of turbine blades while consistently retaining a single crystal structure is to use a technique that does not significantly raise the temperature of the workpiece but still facilitates rapid machining. High-efficiency deep grinding (HEDG) is a relatively new machining technology that uses cubic boron nitride (CBN), super-abrasive grinding wheels at very high speeds.
