Improvement of working parameters of diamond tubular drills by muns of by chromium diamond metalization

Abstract

The results of comparative tests of the tubular drills equipped by unmetallized and metallized by chrome diamonds are represented. On the example of boring of bores in standards it is shown from a granite and white abrasive stone, that at the drills equipped by the metallized diamonds working parameters it is considerably higher. So, specific expense of the metallized diamonds in one and a half and tenfold less at treatment, accordingly, granite and abrasive stone.
