Precision Grinding Alternatives

The lapping process involves passing a part between one or two large flat lap plates or platens in a carrier fluid containing an abrasive Duval achieves a flat polished surface by applying precision surface grinding methods that exceed the flatness of typical rough grinding usually generating surface flatness within .0002 .00005 .

Grinding Machine Guide

Plunge grinding is a type of OD grinding so it also removes material from the outside diameter of a part Where it differs is that the grinding wheel comes in on the diameter and grinds the entire width of that diameter In addition the width of the grinding wheel is always as wide or wider than the length it needs to grind CREEP FEED GRINDING In creep feed grinding the full depth of cut

GRINDING FEEDS AND SPEEDS

In plunge type surface grinding where the entire width of the grinding wheel must penetrate into the work material to the full amount of the downfeed the applicable rates are generally smaller than in transverse grinding 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
