Grinding is the usual method of machining complex components made of nickel-based alloys. This is the most economic process able to achieve the required dimensional and shape accuracies. Since components affecting equipment safety are concerned here, a fabrication process which minimizes damage has top priority. High quality components can be achieved by a uniform grinding process and low machining forces. The continuous in-process dressing while grinding with conventional grinding wheels, and the use of cubic- crystalline boron nitride, CBN, as a new abrasive material offer new means of achieving these objectives.
