Conventional grinding wheels

Vitrified bond (V)

Vitrified bond systems have largely prevailed in precision grinding. A major advantage of vitrified bonding is the controllable porosity. The appropriate microstructure is selected depending upon the size of the contact zone between the work piece and the grinding wheel.

Generally speaking, the larger the contact zone, the more open and porous the grinding wheel needs to be. Highly porous grinding wheels are in particularl needed for productive deep and creep-feed grinding processes to transport the cutting fluid directly into the contact zone and to optimally remove the generated grinding chips and heat. A product of this group is for example the successful KREBS MULTO grinding wheels.

Resinoid bond (B/BF)

The resinoid bond is a bond type well tailored to the grinding task. In resinoid bonds, resins are used as binders, into which fillers are mixed in addition to the abrasive grains. Resinoid-bonded grinding wheels are characterised by having a good cutting performance and cool grinding. Compared with vitrified bonds, resinoid bonds are known as soft, fast and cool grinding bonds. They have a very wide range of applications.

Depending upon the application, the bonds can be used for either dry or wet grinding. Based on the production methods and the low curing temperatures, grinding tools with resinoid bond are usually the least expensive among the different bond systems. Due to the low curing temperature, they can easily be used for all types of abrasives.
