Bit blank grinding method and automatic bit sharpening machine

Abstract

The invention provides a bit blank grinding method and an automatic bit sharpening machine. The bit blank grinding method is characterized in that a bit blank clamp drives bit blank to grind and operate along a path deviating from the circle center of an abrasive disk. The automatic bit sharpening machine realizing the grinding method comprises an abrasive disk assembly and a bit blank clamp assembly; a machine head rotary shaft of the clamp assembly is perpendicular to the transverse shaft of the clamp; and in a direction deviating from the circle center of the abrasive disk, the transverse shaft of the clamp drives the clamped bit blank and the disk surface of the abrasive disk to grind and operate. The technical scheme can automatically grind according to a diamond mesh, so that the grinding efficiency is greatly improved; and especially, manual work is not needed in equipment work, so that the automatic bit sharpening machine becomes the diamond grinding equipment with high degree of automation.

Description

technical field [0001] The application of the present invention relates to a diamond grinding method and a diamond grinding device. Background technique [0002] The rough diamonds are processed into diamonds after sawing, rough grinding, and turning to obtain the specified shape, and then the finished product is finally obtained through fine grinding and polishing of the petal surface. On the grinding machine, the grinding and polishing of each plane of the diamond blank are completed with the grinding disc coated with diamond powder on the surface. Due to the extremely high hardness of the diamond, the grinding strength of the drill surface depends macroscopically on the orientation of the diamond blank and the rotation speed of the grinding disc during the grinding process. Grinding personnel should rotate the drill blank repeatedly based on years of accumulated experience until the surface of the diamond surface is found. The location is positioned along the smallest di...

AI Technical Summary

Problems solved by technology

In the actual grinding of the existing grinding and drilling machine, the grinding personnel must intervene many times, manually judge and adjust the processing direction repeatedly, and manually find the softest direction of the diamond. The work efficiency is low, and the grinding efficiency is lower if the direction is not found. The experience plays a decisive role, the technology is difficult to master, it depends on the accumulation of human experience, the labor intensity is high, and the most important thing is that the processing automation cannot be realized
