GRINDING FEEDS AND SPEEDS

In the transverse grinding process a wheel, substantially wider than the actual cross feed, distributes over its face the developed cutting force, thus permitting higher downfeed rates. The cross feed, which is used in traverse grinding only, is commonly selected to equal a specific part of the wheel width, such as 1/4 to 1/12.
