Characteristics of Resin Bond diamond and cbn Wheels

* Resin bond usually has some added filler such as organic and inorganic materials, metals, etc. into the phenolic resin in order to control its wear resistance, heat resistance, grit retention and lubrication.

* Resin wheels are low in Young′s modulus ; therefore they have excellent characteristics in: processing efficiency, free cutting, surface finish, and minimal chipping.

* Resin bond wheels have shorter wheel life because the adhesion between the grit and the bond is not as strong as that of metal bond wheels. However, resin bond has much better cutting ability when processing hard-to-grind materials such as cermets, ceramics, etc.

* The diamond and CBN abrasives used for resin bond wheels are different from those used for metal bond. They are irregular-shaped and easy to microfracture. By doing so, they also create new cutting edges constantly while grinding. In order to improve grit retention, the diamond is metal-coated and the surface is more uneven shaped.

Resin wheels are typically used for wet grinding, but they can be used for dry grinding by adding some filler to reduce heat generated by grinding and improving their cutting ability.
