Superspeed fiber reinforced resin abrasive cut-off wheel

Abstract

The invention relates to a superspeed fiber reinforced resin abrasive cut-off wheel which comprises an abrasive wheel main body, wherein a center hole is formed in the middle of the abrasive wheel main body, three layers of glass fiber grid cloth are arranged on the abrasive wheel main body and are respectively located on the top face, the middle portion and the bottom face of the abrasive wheel main body and are composite with the abrasive wheel main body. The abrasive wheel main body is formed by 70%-86% of abrasive materials, 7%-19% of binding agent and 5%-12% of padding in a composite mode. According to the superspeed fiber reinforced resin abrasive cut-off wheel, the three layers of the grid cloth are utilized and are formed by being matched with a closed non-metal elastic die, operation is easy, an opening form is easy to achieve, a used linear speed can reach 120 meters per second, and the abrasive cut-off wheel is suitable for being used by a high-speed machine tool with multi-shaft or more than three shafts. A grinding speed can be improved by 100%, radiating performance is good, cutting and grinding are sharp and quick, cutting notch of a workpiece does not be burnt or oxidized, machined materials and self materials of the abrasive wheel are saved, if the size of each of the three layers of the grid cloth is 106*1.5*16, the abrasive cut-off wheel can be used on the multi-shaft high-speed machine tool, once feed is more than 3mm, and the superspeed fiber reinforced resin abrasive cut-off wheel is particularly suitable for machining on deep grooves of hard materials such as die steel and tool steel.

Description

technical field [0001] The invention relates to a cutting grinding wheel, in particular to an ultra-high-speed fiber-reinforced resin cutting grinding wheel. It is especially suitable for multi-axis or three-axis or more machine tools, and the operating speed can reach 120 m / s. Background technique [0002] The abrasives industry is an important and indispensable function in the machine tool industry. Its products are widely used in various industries in the processing and manufacturing industry, and the application fields involved have been continuously expanded in recent years. [0003] With the rapid development of machinery manufacturing, building materials and other industries at home and abroad, it is objectively required for abrasives to adapt to them. Grinding wheels are the main products in the abrasives and abrasives industry. Their cutting and grinding performance is high-quality, efficient, safe and One product with multiple functions and low cost are becoming t...

Problems solved by technology

The internal structure density is tighter, the chip removal blocks the surface of the grinding wheel, and it is easy to burn the workpiece. The heat generated by the friction of cutting metal objects makes the temperature of the grinding wheel cutting piece rise rapidly, thus damaging the mechanical strength of the grinding wheel cutting piece and shortening the use of the grinding wheel cutting piece life
