Metal and ceramic compounded binding agent

Abstract

The invention discloses a metal and ceramic compounded binding agent. The binding agent is characterized by comprising the following matter of, by weight, 35-59 parts of bronze powder, 15-32 parts of boric oxide, 5-14 parts of calcium oxide, 50-60 parts of ceramic powder, 5-16 parts of silicon dioxide, 11-16 parts of titanium mineral, 3-28 parts of borax, 6-17 parts of manganese oxide, 12-25 parts of tin powder, 25-60 parts of gravel, 10-35 parts of iron ore, 3-5 parts of boron carbide and 4-9 parts of calcium stannate. According to the metal and ceramic compounded binding agent, the characteristics of good sharpness and self-sharpening performance of a ceramic binding agent are maintained, the advantages of high rigidity and good shape retention performance of a metal binding agent are achieved, and the comprehensive processing efficiency is improved.

Description

technical field [0001] The invention relates to a metal-ceramic composite binder. Background technique [0002] With the development of science and technology, CNC ultra-precision grinding machines, high-speed and high-precision crankshaft grinding machines and camshaft grinding machines, various high-precision and high-speed special grinding machines, etc., have become one of the key development areas in my country, and the improvement of processing efficiency is the development of CNC grinding machines. important direction. Therefore, CNC grinding machines, especially multi-axis linkage CNC grinding machines, have higher requirements on the performance of diamond grinding wheels, which require good cutting force and sharpness of the grinding wheel; they also require good shape retention of the grinding wheel and continuous processing; at the same time, the grinding wheel is required to be resistant to high heat and strong force extrusion. [0003] Although the traditional...

Problems solved by technology

[0003] Although the traditional resin diamond grinding wheel has good sharpness and self-sharpness, it has low heat resistance, insufficient wear resistance, and short dressing gap, which affects production efficiency; although the vitrified diamond grinding wheel has good sharpness, it has poor wear resistance and is difficult to dress; Although the metal diamond grinding wheel has good shape retention, its self-sharpening is not good, and it cannot meet the needs of continuous processing

[0004] The excellent sharpness, self-sharpness and super wear resistance of the diamond grinding wheel are the key to fully improving the processing efficiency of the CNC grinding machine; and the grinding wheel bond is the key factor affecting the performance of the diamond grinding wheel. The traditional single bond can no longer meet the requirements. The need for the performance of diamond grinding wheels for CNC grinding machines that require high processing efficiency
