tool is used for the turning process. Dry grinding is done by a conventional sin-tered corundum grinding wheel made by Naxos- Diskus Schleifmittelwerke which, like Buderus Schleiftechnik, is a member of the DVS Group. In order to solve the grinding dust problem, the dust is blown out of the grinding gap by a compressed air noz-zle during machining.

The Powerful Potential of Peel Grinding

Feb 01, 2006  Basically, peel grinding uses a narrow grinding wheel, usually 0.25″ (6.4 mm) or less in width, to grind a part. Because the process is much like cutting with a conventional lathe, it is a major competitor to hard turning. The advantages of peel grinding include: Dramatically reduced cycle time. Combined operations. Decreased throughput time.
