金属结合剂金刚石磨具具有强度高、耐磨性好、使用寿命长等特点，被广泛运用

Metal bond diamond abrasive tools have the characteristics of high strength, good wear resistance and long service life. They are widely used in the grinding process of hard materials such as hard alloys, stone materials, ceramics and glass. However, the metal bond diamond grinding wheel prepared by hot pressing sintering has the characteristics of high density, poor self-sharpness, easy clogging, and difficult to repair and shape, resulting in low grinding efficiency of the grinding wheel. This paper attempts to introduce the pore structure of the traditional ceramic bond into the metal bond diamond abrasive tool to prepare the porous metal bond diamond abrasive tool, which makes the self-sharpness more excellent and can reduce the grinding caused by grinding to a certain extent. Force, effectively reduce grinding heat and grinding temperature.

Metal binder diamond abrasives with high strength, good wear resistance, long service life and so on, is widely used in carbide, stone, ceramics, glass and other difficult-to-process materials grinding process. However, the metal binder diamond grinding wheel prepared by the hot press sintering method has the characteristics of high degree of density, poor self-sharpness, easy blockage, difficult to repair and so on, resulting in low grinding efficiency of the grinding wheel. In this paper, we try to introduce the pore structure of traditional ceramic binding agent into the metal binder diamond abrasive, and prepare the multiporous metal binder diamond abrasive, so that its self-sharpness is better, can reduce the grinding force produced by grinding to a certain extent, and effectively reduce the grinding heat and grinding temperature.

Metal bonded diamond grinding tools have the characteristics of high strength, good wear resistance and long service life, which are widely used in the grinding process of hard to process materials such as cemented carbide, stone, ceramics and glass. However, the metal bonded diamond wheel prepared by hot pressing sintering method has the characteristics of high density, poor self sharpening, easy to block and difficult to reshape, which results in low grinding efficiency. In this paper, we try to introduce the pore structure of traditional ceramic bond into the metal bond diamond grinding tool to prepare porous metal bond diamond grinding tool, so that its self sharpness is better, the grinding force produced by grinding can be reduced to a certain extent, and the grinding heat and grinding temperature can be effectively reduced.<br>
