Applicable to grinding of various hard and brittle materials
Newdiamond are committed to manufacturing high quality diamond grinding wheels. Synthetic diamond, as one of the hardest materials in the world, is the main raw material for making superabrasive grinding wheels.
According to the different applications such as ceramics, glass, silicon wafers, gemstones, tungsten carbide, stainless steel, cast iron, PCD materials, stones and other materials,we can choose different sizes of diamond grain, bonded and auxiliary materials , mix them in a certain proportion.
Based on the shape parameters, put it into the corresponding molds for profiling. After the diamond wheels drying, dress them to fully meet the requirements and standards of the drawings. The entire technology is strict to ensure the grinding wheels with features such as high grinding efficiency, high hardness, high wear resistance, and high thermal conductivity.
We are good at producing custom grinding wheels. According to customer’s needs, we can adjust the formula of grinding wheels to meet the special needs such as sharpness, wear resistance, and roughness.
Catagories of Wheels:
Mainly types according to the binder, manufaturing technology and abrasive
Metal Bond Diamond Grinding Wheels
Usually the metal bonded is mainly bronze bond, which features high bonding strength, good wear resistance, with stand large loads, and good thermal conductivity. It is mainly used for non-metallic brittle materials such as ceramics, glass, stone, semiconductor materials, etc.
It is suitable for rough grinding, semi-precision grinding, profiling grinding, cutting, edge grinding, and etc.
In addition to bronze bond, there are also tungsten carbide bonding agents, and iron-based metal bonding agents with iron nickel as the main components, which are suitable for different processing purposes.
Phenolic Resin Bonded Diamond Grinding Wheels
Resin bond diamond wheels are mainly made of thermoplastic phenolic resin as the bonding material, and mix auxiliary filler with a certain amount. It is fully mixed with diamond abrasive at a certain concentration and then hot pressed into the profile. The abrasive retention is slightly lower than that of metal bonded grinding wheels. It has good-self sharpening and less jamming. The binder itself has a certain elasticity and is less likely to cause load.
Vitrified Bond Diamond Grinding Wheels
It is made from vitrified material as the main raw material for bonding, mix auxiliary filler with a certain amount, and mixed with diamond abrasive at a certain concentration. The features are high heat resistance, sharp cutting, high grinding efficiency, less heating and jamming during the grinding process, small thermal expansion, easy control of machining accuracy, and relatively easy dressing.
Polyimide Resin Bond Wheels
Polyimide resin is a high temperature and high strength engineering plastic, which is used for manufacturing diamond grinding wheels to improve the heat resistance. With high hardness, wear resistance, high thermal stability, and low coefficient of expansion, polyimide resin bond diamond wheel is suitable for high hardness ceramics, crystal materials, vitrified bonded materials.It can be used for dry grinding.
Hybrid Bond Diamond Grinding Wheels
Combine metal bond with wear resistance and resin bond with good sharpness, and then mix the diamond abrasives with high quality to make hybrid bond wheels. The hybrid diamond wheels has higher material removal rate, and meanwhile greatly improving its lifespan, and ensuring the surface roughness of the workpieces. It can be used for edge cutting and resharpening of CNC tool.
Electroplated Diamond Grinding Wheels
Diamond is co-deposited into the coating by electroplated technology method, and the diamond does not participate in any chemical reaction. The electroplated diamond grinding wheels have high grinding speed, strong cutting ability and without dressing. We also make the various irregular diamond tools such as diamond rollers dresser .
Vacuum Brazed Diamond Grinding Wheels
The vacuum brazed wheel is composed of diamond, brazing material layer and substrate. It is made by brazing technology based on the principle that chemical reactions can occur between diamond abrasive and brazing material, and metallurgical bonding can occur between brazing material and steel substrate. It has strong abrasive holding force, high diamond exposure height, large chip holding space,low grinding temperature, and suitable for high speed grinding.
Resin CDX (CBN&Diamond) Grinding Wheels
The workpieces are complex and diverse. When there are both hard and brittle materials and composite materials containing black metal elements, the grinding effect of the single superhard abrasive is not good. The diamond and CBN hybrid grinding wheels can achieve the customers’ satisfaction, which is sintered by CBN and diamond abrasives in a specific ratio.

Diamond VS CBN wheels
Another type of superabrasive grinding wheel-CBN grinding wheel is mainly used for grinding black metals containing iron group elements. In practical applications, there is mutual complementation between synthetic diamond and CBN. When choosing the grinding wheels, you can refer to the table below.
