Manufacturing method of abrasive tools

Abstract

The invention relates to a manufacturing method of a grinding tool. Heat dissipation materials are added, the cutting hardness of the grinding tool is ensured, and meanwhile the heat dissipation materials capable of bringing out the heat produced in the working process of the grinding tool are additionally arranged, so that the heat dissipation performance of the grinding tool is ensured, rapid heat dissipation is achieved in the grinding process, the cooling effect is ensured, cooling efficiency is improved, the good performance of the grinding tool is ensured, 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 method for manufacturing an abrasive tool for grinding, polishing and grinding workpieces. Background technique [0002] Organic abrasive tools refer to the use of organic molecular compounds as binders to consolidate abrasive grains together to form a grinding tool with certain rigidity. Organic abrasives include resin abrasives made of natural and synthetic resins as binders, and rubber abrasives made of natural or synthetic rubber binders. [0003] Organic abrasives are generally composed of abrasives, organic binders and pores. Wherein, the organic binder includes resin binder and rubber binder. Polyurethane is a common rubber bond and a common rubber bond. It is a very special special material with good operability. Abrasive tools can be produced through mixing reactions, and the process cost is very low. At the same time, polyurethane is also a soft material with very good elasticity...

AI Technical Summary

Problems solved by technology

[0006] 1) When the coolant is cooled, the cooling effect on bonded abrasives 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) For the binder material itself is a poor conductor of heat, 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 nature of the transition zone between the abrasive and the bond makes the poor combination of the abrasive and the bond directly lead to a sharp decline in the performance of the abrasive tool
