Embodiment Construction

[0036] Below in conjunction with example the present invention will be further described.

[0037] Composite bond grinding wheel, the raw materials used include No. 200 corundum, titanium alloy powder, resin; the raw materials used also include magnesite.

[0038] The manufacture method of composite bond grinding wheel, it comprises the steps:

[0039] step one:

[0040] 1. No. 200 corundum is mixed with titanium alloy powder. Mix and stir No. 200 corundum and metal powder evenly, and the proportion of No. 200 corundum is 70% by weight, and the proportion of metal powder is 30%.

[0041] 2. One-time sintering, inject the above-mentioned mixture into the reaction furnace, sinter at a temperature of 1600°C and a pressure of 50-100MPa, and the sintering time is 60-190m to obtain a sintered block, which is cooled and crushed to obtain a combination of metal and abrasive Particles: Titanium alloy corundum composite abrasive particles.

[0042] Step two:

[0043] 1. Mix and s...

Abstract

The invention relates to the field of grinding tools and abrasives, in particular to a composite binder grinding wheel and a manufacturing method thereof. The composite binder grinding wheel is prepared from raw materials comprising the abrasive, metal powder, an organic binder and magnesia. The manufacturing method comprises the following steps: producing metal composite abrasive particles and ceramic metal composite abrasive particles, then compressing to form a grinding wheel billet, and finally solidifying to form the composite binder grinding wheel. A metal binder, a magnesia binder, a resin binder are sintered with the abrasive particles by stages, and finally the grinding wheel is formed by compression. The performance of the manufactured grinding wheel is significantly improved compared with a single-binder grinding wheel, the manufacture cost of special grinding wheels can be reduced, and the varieties of binders and the varieties of grinding wheels are expanded in grinding wheel manufacturing.

Description

Technical field [0001] The invention involves the abrasive abrasive field, which is specifically for composite binding agent sand wheels and its manufacturing methods. Background technique [0002] The sand wheel is the one with the largest amount of dosage and the most widely used mold in the mold. When used, it can rotate at high speeds. It can be rough, semi -fine grinding and fine grinding, and slotting and cutting of metal or non -metal workpieces.The super -hard grinding wheels made by diamond or cubic boron nitride grinding are widely used in all aspects of grinding fields due to its excellent grinding performance.Vajrayana wheel is a special effects tool for grinding high -hard and crisp materials such as hard alloy, glass, ceramics, and gems.In recent years, with the rapid development of high -speed grinding and ultra -precision grinding technology, higher requirements have been put forward on the wheels. The sand wheels of ceramic and resin binding agents can no longer ...
