1. It is good to use a pink chrome corundum grinding wheel or a microcrystalline corundum grinding wheel.

2. Chrome corundum, code name PA, rose red or pink, hardness similar to white corundum, toughness higher than white corundum, good grinding finish, high grinding efficiency, suitable for quenched steel and alloy steel Sharpening of cutting tools, measuring tools and precision grinding of instrument threads.

3. Microcrystalline corundum, code name MA, is similar in color to brown corundum. The abrasive grains are composed of many tiny crystals. They have high strength, great toughness, and good self-sharpening properties. They are used for powerful grinding and high-finish grinding. cut. Suitable for grinding stainless steel, carbon steel, bearing steel and special ductile iron materials.

3. Also known as bonded abrasives, grinding wheels are bonded abrasives that consolidate ordinary abrasives into a certain shape (mostly circular with a through hole in the center) and have a certain strength. . It is generally composed of abrasives, binders and pores. These three parts are often called the three elements of bonded abrasives. According to different classifications of binders, the common ones are ceramic (bond) grinding wheels, resin (bond) grinding wheels, and rubber (bond) grinding wheels. The grinding wheel is the most commonly used and widely used type of abrasive tools. When used, it rotates at high speed and can be used for rough grinding, semi-finish grinding and grinding of the outer circle, inner circle, flat surface and various profiles of metal or non-metal workpieces. Fine grinding as well as grooving and cutting off, etc.
