Shenzhen drilling company in Shenzhen, Shenzhen drilling wells diamond material PDC drill bit works works basically the same drills and scrapers. Natural diamond drill due to the presence complexity rock breaking mechanism of rock performance at home and abroad and working conditions of their different perspectives, such as grinding, cutting, crushing, plowing, cutting, etc., there has been no unified conclusion, but can be summarized in the following Highlights: 1. Natural diamond drill when drilling some hard formations, in effect pushed the rock drill press to make contact with the diamond rock in a high rock stress state and the presentation of plastic. In plastic formation (or rock under stress showed formation of plastic), eating into the formation and diamond drill torque in the role of the rock in front of the occurrence of internal fragmentation or plastic flow, from the rock matrix, forming debris, the cutting process equivalent to "plow" process called plowing. Roughly equal to the volume of cuttings diamond eating into the rock displacement volume
