Resin Bond Diamond Cutting Wheels Without Steel Plate

Resin bond wheels
Resin bond is usually made with heat-cured resin mainly composed of phenolic resin. Resin bond wheel has excellent grinding ability, surface finish and minimal chipping. It is widely applied for difficult-to-machine material such as tungsten carbide, ceramics, glass, and silicon as well as ferrous materials such as high-speed and sintered ferrous metals.
1 Characteristics of resin bond wheels
①Resin bond usually has some added filler such as organic materials, metals, etc. into the phenolic resin in order to control its wear resistance, heat resistance, grit retention and lubrication.
②Resin wheel are low in young’s modulus; therefore they have excellent characteristics in: processing efficiency, free cutting, surface finish, and minimal chipping.
③Resin 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 material such as cermets, ceramics, etc.
④The diamond and CBN abrasive used for resin bond wheels are different from those used for metal bond. They are irregular-shaped and easy to micro-fracture. By doing so, they also create new cutting edge constantly while grinding. In order to improved grit retention, the diamond is metal-coated and the surface is more uneven shaped.
⑤Resin wheel are typically used for wet grinding, but they can be for dry grinding by adding some filler to reduce heat generated by grinding and improving their cutting ability.
2Applications of diamond wheels
①Resin bond diamond wheels are mostly used for precision grinding wheel of tungsten carbide, cermets and ceramics.
②Because of the bond elasticity, they are used for finish grinding of silicon, glass, ceramic-made electrical parts, etc. which require excellent surface finish.
3Application of CBN wheels
①Resin bond wheels are suitable for grinding ferrous metal such as cast iron, high speed steels, and sintered iron.
②They are suitable for processing hard to machine materials because CBN grains are much stronger than conventional abrasives.
③They can perform precision grinding because they wear much less than conventional abrasives.
