Abstract

A process for preparing the adhesive disc with photosensitive resin as adhesive includes such steps as preparing the metallic base of abrasive disc, mixing photosensitive resin with abrasive particles, stirring, installing said metallic base onto rotary platform, rotating, coating said mixture on one surface of metallic base, optical solidifying, coating the mixture on its back, and optical solidifying.

Description

1. Technical field [0001] The invention relates to a method for preparing a metal base grinding wheel, and is especially suitable for the preparation of a photosensitive resin bonded grinding wheel. 2. Background technology [0002] Abrasives are the main tools used in large quantities in the machinery manufacturing industry and are also the main consumables. The grinding wheel is the main representative of abrasives. At present, the binder of resin bonded grinding wheel used at home and abroad mainly adopts thermosetting resin represented by aldehyde phenol resin, and the abrasive grains are combined by heating and sintering. This manufacturing process is as follows: mixing materials, mixing them with a mixer The abrasive grains are evenly mixed with the resin bond; molding, put the uniformly mixed abrasive grains and resin into the molding mold, and press to form by a press; solidify, the pressed cutting grinding wheel is heated and kept in an electric heating furnace, and...
