Matrix Pdc Bit

The bit body of matrix pdc bit is made of cast tungsten carbide powder and impregnating material through pressureless impregnation sintering. The shape of the bit body is indirectly realized through the shape of the die. The mold is composed of bottom mold, middle mold and upper mold. The design and processing of the middle die and upper die of the die are easy to realize. However, the bottom die is a solid body with complex surface characteristics. The crown shape parameters, cutting tooth position and direction parameters, hydraulic structure parameters of the matrix pdc bit are all realized through the shape of the bottom die. Therefore, the design and processing of the bottom die is the most important in the die design and processing. Therefore, the quality of the design and processing accuracy of this matrix bottom die are directly related to the quality of the diamond composite bit. The quality of matrix depends on the quality of abrasive tools, which is the most important part of the quality of matrix pdc bit.
