Problems solved by technology

[0005] The diameter of the existing grinding wheel is 200mm, and the centrifugal force is too large after rotation. Due to the excessive load on the spindle, the wear resistance of the grinding wheel is poor, resulting in a high failure rate of the machine tool, and the time for machine tool shutdown to change the grinding wheel is too long.

Abstract

The invention relates to the field of materials, in particular to a composition and a grinding wheel made of the composition. Through targeted design, the diameter of the grinding wheel is reduced to125 mm, dynamic balance is carried out well, the load of a main shaft is remarkably reduced, and the service life of the main shaft is greatly prolonged. According to the composition and the grindingwheel, by means of the design of a grinding material layer formula and by selecting an appropriate grinding material to carry out testing, the service life of the single grinding wheel is prolonged to28 days at present from the original 6 days under the situation of guaranteeing the qualified workpiece quality. Continuous operation of an assembly line is guaranteed, the usage rate of the assemblyline is increased, the labor hour waste of shutdown caused by changing the grinding wheel is greatly reduced, and the cost performance of the grinding wheel is increased.

Description

technical field [0001] The invention relates to the field of materials, in particular to the composition and the prepared grinding wheel. Background technique [0002] Crystalline silicon materials (including polycrystalline silicon and monocrystalline silicon) are the most important photovoltaic materials, with a market share of more than 90%, and will still be the mainstream material of solar cells for a long period of time in the future. The production technology of polysilicon materials has been in the hands of 10 factories of 7 companies in 3 countries including the United States, Japan and Germany for a long time, forming a situation of technology blockade and market monopoly. [0003] The demand for polysilicon mainly comes from semiconductors and solar cells. According to different purity requirements, it is divided into electronic grade and solar grade. Among them, electronic-grade polysilicon accounts for about 55%, and solar-grade polysilicon accounts for 45%. W...
