Abstract

The invention relates to an integrated type ultrathin resin grinding wheel with ultrahigh cutting perpendicularity. The grinding wheel comprises, by volume, 10-25 part of abrasive materials, 40-50 parts of resin binders and 10-40 parts of padding. Chopped fibers composed of carbon fibers and / or glass fibers are adopted as the padding, wherein the diameter of each chopped fiber is 5-20 micrometers, the length of each chopped fiber is 50-500 micrometers, and the length-diameter ratio of each chopped fiber is (10-100):1. Compared with an integrated type ultrathin resin grinding wheel made of traditional padding, the cutting perpendicularity of the integrated type ultrathin resin grinding wheel is obviously improved, a kerf can be reduced at least by about 0.01 mm, and the cutting perpendicularity is improved at least by about 28.6%; the grinding wheel is not prone to breakage, the dimension of a cut workpiece is good, and the cutting quality is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of abrasive tool manufacturing, and in particular relates to an ultra-high cutting verticality integral ultra-thin resin grinding wheel and a preparation method thereof. Background technique [0002] The thickness of the integral ultra-thin resin grinding wheel is generally 0.06 mm ~ 0.5 mm, without a matrix, and the structure is as follows figure 1 shown. This type of grinding wheel is mainly suitable for high-precision cutting and grooving of optical glass, ceramics and semiconductor packaging materials. This type of grinding wheel has the advantages of good self-sharpening, high cutting efficiency and good cutting quality, and is an indispensable tool for realizing high efficiency, energy saving, high precision and automatic cutting processing. Although the integral ultra-thin resin grinding wheel has a high cutting verticality, further improving the cutting verticality still plays an important role in ...
