Ultra-precision grinding of asymmetric curved . - SAGE Journals

Abstract. The wheel wear is a crucial factor affecting the shape accuracy while grinding the asymmetric curved surface compo- nents. To decrease the effects of the wheel wear and improve the machining accuracy, a novel approach of grinding with large-size and fine-grained cup wheel was suggested. This method has.

Grinding Spindles Take Grease To Higher Speed : Modern Machine .

Conventional wisdom has it that grease lubrication is fine for grinding spindles so long as speeds stay fairly low. As speed approaches 10,000 to 15,000 rpm, however, then heat becomes a major problem, leaving little choice but to go to an oil-and-air mist system. Or so the thinking goes. But according to GTI Spindle.
