Grinding wheel with potassium and sulfur compound

Abstract

The invention discloses a grinding wheel with a potassium and sulfur compound. The grinding wheel comprises a grinding wheel base body. Hexagonal shallow grooves and a gear opening are machined in thegrinding wheel base body, and the gear opening is in butt joint with the hexagonal shallow grooves in the outermost edge. The grinding wheel is further sequentially coated with a grinding wheel resinlayer, a potassium and sulfur compound layer and an abrasive layer. The grinding wheel with the potassium and sulfur compound is specific to the problem that when a traditional grinding wheel is usedfor grinding a workpiece, the transient temperature can reach 600 DEG C, a workpiece is likely to be damaged, and the grinding wheel is likely to be damaged, the potassium and sulfur compound is added in the grinding wheel preparing process, the melting point of the potassium and sulfur compound is only 480 DEG C, and the potassium and sulfur compound can be melted enough under the grinding high-temperature condition; and meanwhile, the hexagonal shallow grooves and the gear opening are machined in the grinding wheel so that the molten liquid potassium and sulfur compound can seep from the hexagonal shallow grooves and be transited to the cutting edge position of the grinding wheel through the gear opening, the cut workpiece is effectively cooled, the temperature of the cut workpiece is low, the cutting speed is high, the cutting efficiency is greatly improved, and the cutting time is shortened.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a grinding wheel sheet with potassium-sulfur compound. Background technique [0002] At present, grinding wheel grinding is generally used for finishing parts. Most of the grinding wheel manufacturing methods used in grinding process adopt integral structure. If the grinding wheel is damaged during the processing, it will not be able to continue to work. Replace the entire grinding wheel, and often the damage of the grinding wheel comes from the grinding damage of the cutting workpiece, because the instantaneous temperature of the cutting workpiece reaches a high temperature of 600 ° C, which is easy to reduce the stiffness of the grinding port of the grinding wheel. Cooling and reprocessing will result in reduced processing efficiency and greater damage to the workpiece. Contents of the invention [0003] The object of the present invention is to provide a grinding wh...
