ABRASIVE SHEETING HAVING INDIVIDUALLY POSITIONED ABRASIVE GRANULES |
摘要 |
Abrasive sheeting can produce fine finishes at surprisingly high cutting rates when its abrasive granules are individually positioned in a predetermined pattern, with an uncoated portion of virtually every granule protruding from the surface of the binder layer. Each of the abrasive granules preferably is a spherical composite of a large number of abrasive grains in a binder. For example, abrasive grains having a mean dimension of about 4 .mu.m can be bonded together to form spherical abrasive granules of virtually identical diameters, preferably within a range of from 25 to 100 .mu.m. |
