The important role of binding agent in the manufacture of grinding wheel

Binding agents may be attached to the abrasive wheel using a variety of materials, and the nature of the type of binding agent directly affects the grinding wheel hardness, strength. Since the grinding wheel grinding carried out in high-speed rotation, and is in high temperature, high pressure, high impact loads as well as under conditions of strong corrosive fluid cutting work, so the strength of a solid abrasive paste, binder itself heat, corrosion resistance , has become an important requirement for binding agents.

Commonly used grinding wheel bond the following three:

Inorganic binder, commonly used ceramics.

Organic binding agent, commonly used resin and rubber.

Metal binding agent for part of the diamond and boron nitride grinding wheels.

For example vitrified, with its bonded grinding wheel, its stable physical and chemical properties, the gap more, can better maintain the geometry of the grinding wheel, cold, hot, dry, wet adaptation, and are not afraid water, oil, acids, alkalis, the price is cheap, so widely used. But the use of vitrified bonded grinding wheel brittle texture, lack of flexibility, can not withstand the impact of large and twisted side pressure, not manufacturing thin grinding wheel peripheral speed of the grinding wheel is generally only 35m / s or less. Each binder has the advantages of its use, the user has the choice of targeted, in order to play a role in a full range of applications.
