Use of Extremely Hard Soviet Abrasives for Precision Machining,

Abstract

The evaluation of the Soviet literature shows that synthetic polycrystalline diamonds and tools mounted with 'Elbor-R' can be used in precision machining. The efficiency of these tools equals or exceeds that of natural diamonds. This review and the information contained therein should serve as a stimulus and an orientation for a use of the tools discussed. The documentation of the VEB First Machine Shop of Carl Marx City is recommended to those interested in turning with 'Elbor-R' turning tools, since important details and examples of machining are spelled out there. Finally, it can be stated that particularly 'Elbor-R' tools significantly widen the machining of hardened iron materials that previously were machinable only by grinding or electro-erosivally or electro-chemically, they make possible the heat treatment of steels before the chip-removing machining operation, and they can partially replace grinding by turning or drilling.
