Brazed diamond combination abrasive belt, finishing device and finishing method of device

Abstract

The invention provides a brazed diamond combination abrasive belt, a finishing device and a finishing method of the device, wherein the brazed diamond combination abrasive belt comprises an annular steel belt and a plurality of brazed combination blocks uniformly distributed on the annular steel belt along the circumferential direction, a mounting groove for clamping the brazing combination blockon the annular steel belt is arranged at the bottom of each brazing combination block, the middle position of the top of each brazing combination block is sunken downward to form a transverse bucklinggroove protruding forward or backward, and brazing abrasive particle layers are arranged in positions, on two sides of the transverse buckling groove, of the top of each brazing combination block. According to the invention, a superhard abrasive grinding wheel is finished by adopting the improved brazed diamond combination sand belt, the defects of single-point finishing and line finishing adopted in a conventional finishing process are overcome, the finishing difficulty and finishing efficiency of the superhard abrasive grinding wheel are greatly reduced by adopting a small-area fitting finishing method, the sharpening effect of the superhard abrasive grinding wheel is enhanced, and the finishing difficulty of the superhard abrasive grinding wheel is reduced.

Description

technical field [0001] The invention relates to the technical field of dressing devices for superhard abrasive grinding wheels, in particular to a brazed diamond combined abrasive belt, a dressing device and a dressing method for the device. Background technique [0002] Superabrasive grinding wheels are one of the most difficult grinding wheels to dress. At present, there are various dressing methods for superabrasive grinding wheels in the industry. Among them, mechanical dressing methods mainly include the following four types: single point diamond pen dressing, diamond disc Wheel dressing, wheel dresser dressing and cup wheel dressing. The first two kinds of dressing belong to single-point dressing, and the latter two kinds of dressing belong to line dressing. During the dressing process of the above dressing methods, the diamond abrasive grains in the dresser will encounter more abrasive grains to be dressed. For the dressing of superabrasive grinding wheels Generally ...
