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.
