A kind of high-speed and heavy-duty grinding wheel of superhard material metal-bonded skeleton type

Abstract

The invention provides a superhard material metal bond framework type high-speed heavy load grinding wheel and belongs to the technical field of grinding wheel manufacture. The grinding wheel comprises a grinding wheel substrate, a superhard material metal bond framework, a filling material, a cushion block and a connecting block. The grinding wheel is prepared by the following steps of selecting a material of the grinding wheel substrate; preparing and installing the superhard material metal bond framework, wherein the superhard material metal bond framework is prepared from a superhard material and a high-strength steel plate through electroplating brazing, stamping, or pressure sintering by using metal powder cobalt, nickel, iron, copper and tin, and is fixed to the grinding wheel substrate in a welding or resin cementing method; extruding the filling material between the superhard material metal bond framework, and performing dynamic balance or static balance and the like to obtain the high-speed heavy load grinding wheel. The high-speed heavy load grinding wheel is long in service life, the cost can be greatly reduced, and the high-speed heavy load grinding wheel has the characteristics of safe use, energy conservation and environment friendliness.

Description

Technical field: [0001] The invention belongs to the technical field of grinding wheel manufacturing, in particular to a high-speed and heavy-duty grinding wheel of superhard material metal-bonded base skeleton type. Background technique: [0002] At present, high-speed and heavy-duty grinding wheels are widely used in steel, machinery, railway and other industries to grind steel billets, steel products, rolls and railway track surfaces, etc. The grinding wheels are almost all corundum or silicon carbide resin grinding wheels with high energy consumption. Big, also cause environmental pollution simultaneously and grinding cost is high and emery wheel often bursts and causes unsafe, and service life is shorter. How to use superhard materials such as CBN or diamond to replace corundum and silicon carbide abrasives with high energy consumption has become a major issue in this industry. At present, only metal-bonded superhard material grinding wheels are wear-resistant, durable ...

Problems solved by technology

[0002] At present, high-speed and heavy-duty grinding wheels are widely used in steel, machinery, railway and other industries to grind steel billets, steel products, rolls and railway track surfaces, etc. The grinding wheels are almost all corundum or silicon carbide resin grinding wheels with high energy consumption. Large, but also cause environmental pollution and high grinding costs and frequent bursting of the grinding wheel is unsafe, and the service life is short

How to use superhard materials such as CBN or diamond to replace corundum and silicon carbide abrasives with high energy consumption has become a major issue in this industry. At present, only metal-bonded superhard material grinding wheels are wear-resistant, durable and able to withstand heavy loads, and have high It is characterized by high speed, high efficiency and safe and reliable use, but the fatal problem of the existing metal-bonded superhard material grinding wheel is the difficulty in chip removal. After several hours of use, it must be removed from the equipment and corrected by electric spark or electrolytic correction on the machine tool After that, it will be used again, which will seriously affect the production and the popularization and application of this type of grinding wheel.
