What are the classification of grinding wheels?

Grinding wheel bai is also called consolidated abrasive. Grinding wheel is used to consolidate du ordinary abrasive into a certain shape (mostly round, with a through hole in the center), and has a certain strength of consolidated abrasive. It is generally composed of abrasives, bonding agents and pores. These three parts are often called the three elements of consolidated abrasives.

According to the different classifications of bonding agents, there are ceramic (bonding agent) grinding wheels, resin (bonding agent) grinding wheels, and rubber (bonding agent) grinding wheels. The grinding wheel is the one with the largest amount and the most widely used surface in the grinding tool. It rotates at high speed during use. It can perform rough grinding, semi-finish grinding on the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces. Fine grinding and slotting and cutting.

There are many types of grinding wheels.

According to the abrasive used, it can be divided into ordinary abrasive (corundum and silicon carbide, etc.) grinding wheel and natural abrasive superhard abrasive and (diamond and cubic boron nitride, etc.) grinding wheel;

According to the shape, it can be divided into flat grinding wheel, bevel grinding wheel, cylindrical grinding wheel, cup grinding wheel, dish grinding wheel, etc.; according to the bonding agent, it can be divided into ceramic grinding wheel, resin grinding wheel, rubber grinding wheel, metal grinding wheel, etc.

The characteristic parameters of the grinding wheel mainly include abrasive, particle size, hardness, bonding agent, shape, size and so on. Since the grinding wheel usually works at high speed, the rotary test (to ensure that the grinding wheel will not break at the working speed) and the static balance test (to prevent vibration of the machine tool during work) should be carried out before use. After working for a period of time, the grinding wheel should be trimmed to restore the grinding performance and the correct geometry.

Grinding wheels are the most important type of abrasive tools in grinding. The grinding wheel is a porous body made by adding a binder to the abrasive, compacted, dried and roasted.

Due to the different abrasives, bonding agents and manufacturing processes, the characteristics of the grinding wheel vary greatly, so it has an important impact on the processing quality, productivity and economy of grinding. The characteristics of the grinding wheel are mainly determined by factors such as abrasive, particle size, binder, hardness, structure, shape and size.
