Abstract
Abstract. The cutting mechanical properties of impregnated diamond bit depend on the performance of its cutting elements. Aiming at the factors affecting the
cutting element performance of impregnated diamond bit, the laboratory rock breaking experiment of impregnated micro bit is carried out. The results
show that the breaking work ratio and unit wear first decrease and then increase with the increase of diamond particle size and concentration when
drilling sandstone; the rock breaking efficiency and wear resistance are the highest when the concentration is 125 %. The breaking work ratio
first decreases and then increases with the increase of diamond particle size when drilling limestone; the rock cutting efficiency is the highest
when the concentration is 100 %. With the increase of diamond particle size, the breaking work ratio increases and the unit wear decreases when
drilling granite; the rock cutting efficiency and wear resistance are the highest when the concentration is 150 %.
期刊介绍：
The journal Mechanical Sciences (MS) is an international forum for the dissemination of original contributions in the field of theoretical and applied mechanics. Its main ambition is to provide a platform for young researchers to build up a portfolio of high-quality peer-reviewed journal articles. To this end we employ an open-access publication model with moderate page charges, aiming for fast publication and great citation opportunities. A large board of reputable editors makes this possible. The journal will also publish special issues dealing with the current state of the art and future research directions in mechanical sciences. While in-depth research articles are preferred, review articles and short communications will also be considered. We intend and believe to provide a means of publication which complements established journals in the field.
