Braze-welding superhard abrasive grinding pan for flexible grinding

Abstract

The invention discloses a braze-welding superhard abrasive grinding pan for flexible grinding. The braze-welding superhard abrasive grinding pan comprises a superhard abrasive, a welding lining layer and a supporting layer, wherein the supporting layer is of a disc-shaped structure; the supporting layer is provided with a mounting hole connected with polishing equipment; the welding lining layer is fixedly arranged on the disc surface of the supporting layer; the welding lining layer is formed by weaving metallic wires and nonmetallic high-temperature-resistant fibers in a mixed manner; the high temperatures to which the metallic wires and the nonmetallic high-temperature-resistant fibers are resistant are all not lower than 550 DEG C, wherein the metallic wires can generate chemical metallurgical bonding with an alloy welding flux for braze welding, and the nonmetallic high-temperature-resistant fibers cannot generate the chemical metallurgical bonding with the alloy welding flux for braze welding; and single grains or a cluster-shaped single layer of the superhard abrasive is uniformly distributed on the surface of the welding lining layer, and is subjected to braze-welding fixation through the alloy welding flux. After the structure is adopted, the braze-welding superhard abrasive grinding pan can be used for polishing metallic, nonmetallic and composite materials, and can be used for polishing multiple molded surfaces and angles; during polishing, the vibration is slight, the noise is low, and the hand feeling is light; and characteristics of being sharp in grinding, long in service life, small in spark, small in mill dust, and the like, can be achieved.

Description

technical field [0001] The invention relates to the field of superhard abrasive tool preparation, in particular to a brazed superhard abrasive disc for flexible grinding. Background technique [0002] Brazed superabrasive grinding discs are formed by welding superabrasives on a steel substrate by a brazing process. However, since the superabrasive is directly exposed after brazing, it is in direct contact with the material, rigidly ground, with high noise and high vibration. Rigid grinding discs have certain restrictions on the grinding objects, and some corners, grooves, etc. cannot be polished well. Moreover, due to the high rigidity of the grinding disc, for some occasions that require precise grinding and polishing, traditional superhard abrasive tools are more difficult to do. On the contrary, products such as hundred-page wheels and polishing pads have more advantages, but their service life is short and there are certain limitations. sex. Therefore, in the field of...
