Abstract

The invention relates to a material for manufacturing a grinding wheel and a manufacturing method for the grinding wheel. The material contains the following substances by weight percent: a grinding material and a binding material, wherein the grinding material is prepared by mixing the following substances by weight percent: plastic raw material, diamond powder and blue wax powder; the plastic raw material, the diamond powder and the blue wax powder are served as the grinding material; the plastic is formed by mixing hydrogenated nitrile rubber, polypropylene and medium alkali containing glass fiber; the hydrogenated nitrile rubber is suitable for higher temperature and is not adhered to a cutting tool under the effect of high temperature in a grinding process; the polypropylene is easily molded and has a certain adhesive effect; the medium alkali containing glass fiber is capable of increasing the hardness of the grinding wheel and bearing larger centrifugal acting force; the diamond powder can increase the grinding precision and grinding speed of the grinding wheel; the blue wax can enhance the polishing effect and increase the smoothness of the cutting tool. The grinding wheel prepared from the material is high in processing precision and smoothness in the passivation process of the cutting tool.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a material for making grinding wheels and a manufacturing method of grinding wheels. Background technique [0002] In the production process of knives, it is not only necessary to grind the blade of the knives to make the knives sharper, but also to passivate the knives. After the passivation treatment, the blade of the tool forms a rounded corner, which is not easy to crack, and the service life is increased. Existing single crystal diamond tools are ground and passivated by grinding wheels, and the material of the grinding wheels plays a very important role in the processing of the tools, while the existing grinding wheels have low machining accuracy and efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a material for making a grinding wheel and a method for manufacturing a grinding wheel, aiming ...
