Abstract

The invention discloses a method for manufacturing a marble cutter bit and a matrix material adopted for the method for the manufacturing the marble cuter bit. The matrix material of a diamond section in the marble cutter bit mainly comprises Cu-Zn-Sn alloy powder, Cu powder and Cu-Co-Fe alloy powder. The content of the low-melting-point metal component Sn and the content of low-melting-point metal component Zn in the matrix material are low, and the sintering temperature is high and can reach 820 DEG C and 860 DEG C. In the welding stage, the matrix material can be adaptive to the brazing technology, the cutter bit does not expand and is free of burning loss deformation and low in welding cost in the welding process, and the cutter bit has the cost competitive advantage and is broad in market prospect. Tests show that the bending strength of the marble cutter bit manufactured with the method ranges from 1000 Mpa to 1400 Mpa, and the hardness of the marble cutter bit manufactured with the method ranges from 80 HRB to 95 HRB; tests with a bridge cutting testing machine show that the power consumption ranges from 6 KW to 7 KW, the service life of the marble cutter bit can be 20 to 24 m<2>/mm, and compared with an exiting marble cutter bit, the marble cutter bit manufactured with the method has the advantages that the power consumption is lower and the service life is longer.

Description

Technical field [0001] The invention relates to the field of diamond tools, in particular to a method for preparing a marble cutter head and a used matrix material. Background technique [0002] The carcass is the metal sintered body of diamond. The role of the carcass is to hold the diamond so that it can cut it without falling off prematurely. For traditional marble cutter heads, the sintering temperature of the matrix material of the diamond segment is 680-720°C, which requires low welding temperature. Only the silver welding process can be used in the welding stage. Silver solder is expensive and the product cost is high. Summary of the invention [0003] The purpose of the present invention is to provide a method for preparing a marble cutter head. The sintering temperature of the diamond segment of the marble cutter head prepared by this method is 820-860 DEG C. The welding stage can be adapted to the brazing process and the cost is low. [0004] Another object of the present...
