摘要:
A process for manufacturing an upper work roller for use in the deep rolling of crankshafts including the steps of: rough sawing tool steel to form a generally cylindrical wafer, heat treating said wafer to provide it with a desired hardness, grinding of said wafer to desired dimensions to form a properly dimensioned heat treated blank wafer, a second grinding of said wafer to form a finished shape of work roller, and vibratory finishing said roller to achieve a desired microfinish thereon.
