Abrasives with heat dissipation structure

Abstract

The invention relates to a grinding tool provided with a heat dissipation structure. The grinding tool consists of a grinding layer and a heat dissipation layer which are integrated, wherein the outer end of the heat dissipation layer outwards extends to form a plurality of heat dissipation strips. According to the grinding tool provided with the heat dissipation structure, under a condition of guaranteeing the cutting hardness of the grinding tool provided with the heat dissipation structure, the heat dissipation structure is additionally arranged on the grinding tool, so that the heat dissipation performance of the grinding tool is guaranteed, and heat dissipation can be quickly carried out in a grinding process to guarantee the cooling effect and improve the cooling efficiency; and therefore, the grinding tool is high in performance, and the service life of the grinding tool is prolonged.

Description

technical field [0001] The invention relates to a grinding work, in particular to a grinding tool with a heat dissipation structure for grinding, polishing and grinding workpieces, and a preparation method of the grinding tool with a heat dissipation structure. Background technique [0002] The organic abrasive tool with heat dissipation structure refers to the use of organic molecular compounds as binders to consolidate the abrasive grains together to form a grinding tool with a certain rigidity. Organic abrasive tools with heat dissipation structure include resin abrasive tools with heat dissipation structure made of natural and synthetic resin binders, and rubber abrasive tools with heat dissipation structure made of natural or synthetic rubber binders. [0003] Organic abrasive tools with heat dissipation structure are generally composed of abrasives, organic binders and pores. Wherein, the organic binder includes resin binder and rubber binder. Polyurethane is a commo...

AI Technical Summary

Problems solved by technology

[0006] 1) When the coolant is cooled, the cooling effect of the abrasive tool with a heat dissipation structure for the binder with a temperature resistance lower than 200 °C is not ideal;

[0007] 2) For an environment with a relatively large grinding contact area (such as a large contact surface when grinding a cup-shaped grinding wheel), the coolant cannot enter the working surface well, resulting in cooling failure;

[0008] 3) The binder material itself is a poor conductor of heat, so the high temperature generated locally by the abrasive during the grinding process cannot be quickly transmitted to form a heat dissipation effect, so the local high temperature of up to 800 ° C will also greatly affect the The transition zone properties of the abrasive and the bonding agent make the abrasive and the bonding agent not well bonded, which directly leads to a sharp decline in the performance of the abrasive tool with a heat dissipation structure
