Embodiment Construction

[0013] component name

[0014] 1) Use a mixer to stir the abrasive grains and liquid resin evenly according to the above formula to form a uniform mixture.

[0015] 2), inject the mixed raw materials into the molding mold to form the above shape and size,

[0016] 3) Put the raw material formed in the forming mold in the above-mentioned equipment, so that the light irradiation area covers the width of the cutting wheel, rotate the mold once or irradiate the light source along the cutting wheel for one week, so that the wheel is hardened, and the light wavelength distribution ranges from 200 nm to 500 nm , the light intensity is 2.4w / cm 2 . Hardening time is 15 seconds.

Abstract

The quick preparation method of abrasive cut-off wheel includes the following steps: uniformly mixing abrasive powder and liquid binder, stirring them to form uniformly mixed liquid, injecting said mixed liquid into mould and forming, then illumination and hardening to obtain the invented product. The weight ratio of binder and abrasive powder is 1:0.05-1, and its binder can be photo-hardening resin, and in the binder the micropowder of fibre also can be added. Its preparation time is short, energy consumption also can be greatly reduced, and its production cost also is reduced.

Description

technical field [0001] The invention relates to a preparation method of a cutting grinding wheel, which is used for precise cutting of hard and brittle materials represented by semiconductor materials, ceramics, crystals, gemstones, glass, etc. and other materials. Background technique [0002] The current precision cutting grinding wheel is prepared by heating and sintering. It uses a mixer to mix the abrasive grains and the binder evenly, then puts the mixture into a molding mold, and presses it to form it with a press. The pressed cutting wheel is heated and kept in an electric heating furnace, and passed through a temperature of several hundred degrees Celsius. 1 to 2 hours of sintering. The disadvantages of this method are large energy consumption, high cost, poor working environment, long production time and cannot provide quick service for users. Contents of the invention [0003] The technical problem to be solved by th...
