Grinding wheel capable of easily removing chips

Abstract

The invention discloses a grinding wheel capable of easily removing chips. The grinding wheel comprises a grinding wheel substrate; a mounting shaft hole is formed in the center of the grinding wheelsubstrate; a material grinding layer is disposed on one side of the grinding wheel substrate; a receding mounting hole which corresponds to the mounting shaft hole is formed in the center of the material grinding layer; a plurality of protruding edges are radially disposed on the end surface, making contact with a workpiece, of the material grinding layer and are uniformly distributed on the mentioned end surface; radial-extending arc-shaped grooves are formed between the protruding edges and formed in the material grinding layer; bosses are disposed on the protruding edges; and inwards-concave grooves which are embedded into the bosses are formed in the end surface, making contact with the workpiece, of the material grinding layer. By means of the structure with the protruding edges and the arc-shaped grooves, the chip removing capacity and the heat dissipation capacity of the grinding wheel can be effectively improved, the grinding accuracy of the grinding wheel is improved, and theservice life of the grinding wheel is prolonged.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to an easy chip removal grinding wheel. Background technique [0002] At present, the commonly used shapes of grinding wheels include parallel grinding wheel, single concave grinding wheel, double-sided concave grinding wheel, thin slice grinding wheel, cylindrical grinding wheel, bowl-shaped grinding wheel, butterfly grinding wheel and so on. In engineering use, when the grinding wheel is grinding or cutting materials, the grinding contact area between the grinding wheel and the workpiece is large, and the grinding heat is difficult to discharge in time, thus forming a local high temperature on the grinding surface, causing problems such as burns and cracks on the surface of the workpiece, which are serious It affects the surface processing quality of the workpiece, and accelerates the wear of the grinding wheel, which restricts the further popularization and application of...

Problems solved by technology

In engineering use, when the grinding wheel is grinding or cutting materials, the grinding contact area between the grinding wheel and the workpiece is large, and the grinding heat is difficult to discharge in time, thus forming a local high temperature on the grinding surface, causing problems such as burns and cracks on the surface of the workpiece, which are serious It affects the surface processing quality of the workpiece, and accelerates the wear of the grinding wheel, which restricts the further popularization and application of grinding technology

In addition, after the grinding wheel has been used for a period of time, if a local wear defect occurs, the entire grinding wheel needs to be replaced, resulting in serious waste

[0003] Application number 201521112770.1 discloses a grinding wheel with chip removal grooves, which has multiple chip removal grooves radially on the side where the abrasive layer is in contact with the workpiece, but its chip removal capacity is not ideal enough, and the bottom of the chip removal grooves For rectangular corners, it is easy to cause accumulation of wear debris and affect the effect of chip removal

Application No. 201020166002.5 discloses a grinding wheel that is easy to dissipate heat. The adopted technical solution is to connect the aluminum core through the hole in the center of the grinding wheel disc body and design annular grooves on the upper and lower surfaces of the disc body for heat dissipation, but the heat dissipation effect is not very satisfactory. There is no relationship between the grooves, which will affect the heat dissipation effect, and it will easily cause abrasive debris filling and poor chip removal, scratching the surface of the workpiece
