Research of operating characteristics of АВКМ insertions at boring of granit plastins in laboratory conditions

Abstract

Results over of tests are brought in the laboratory terms of the insertions of АВКМ, envisaged in specially worked out and constructed steel insertions. The insertions of АВКМ contained the diamonds of different brands and size. It is shown that with the increase of concentration of natural and synthetic diamonds in АВКМ operating descriptions of instrument get better: boring speed increases and his wear diminishes. Offered and mastered methodology of tests such insertions designs their industrial tests in boring crownsat the geological survey boring drilling of KП (public enterprise).
