what type of grinding wheels are used to grind pcd inserts?

PCD inserts are used for high speed and high precision cutting 

Polycrystalline diamond (PCD) inserts are a popular tool in modern machining processes, as they offer many benefits over traditional cutting tools made of other materials. PCD is a hard and durable material that can withstand the high-speed and high-pressure conditions of modern machining operations. However, PCD is not easily machinable with conventional grinding wheels. This is why specialized grinding wheels are required for grinding PCD inserts.

Vitrified bond diamond grinding wheel for grinding PCD inserts

The most common types of grinding wheels used for grinding PCD inserts are vitrified bond diamond grinding wheels and resin bond diamond grinding wheels. Vitrified bond diamond grinding wheels are made by mixing synthetic diamond powder with a vitrified binder material and then sintering the mixture under heat and pressure to create a porous grinding wheel. The diamond particles are embedded into the pores of the grinding wheel, providing the necessary abrasion and toughness to grind hard and abrasive materials like PCD. This type of grinding wheel offers excellent dimensional accuracy, surface finish, and long wheel life, making it an ideal choice for grinding PCD inserts.

Resin bond diamond grinding wheel for high removal rate grinding for PCD inserts

Resin bond diamond grinding wheels, on the other hand, are made using a resin binder material mixed with synthetic diamond powder. The resin bonds the diamond particles together, creating a strong and durable grinding wheel that is suitable for grinding PCD inserts. This type of grinding wheel is ideal for applications where a high removal rate is required, as they offer superior cutting ability and are less likely to glaze over.

Grinding wheel specifications commonly used for grinding PCD inserts

In addition to the type of grinding wheel, the size and shape of the grinding wheel are also crucial factors to consider when grinding PCD inserts. The size of the grinding wheel should be appropriate for the size of the insert being ground to ensure optimal performance. Furthermore, the shape of the grinding wheel must match the desired profile of the insert to ensure accurate grinding of the insert’s profile.

In conclusion, the grinding of PCD inserts requires specialized grinding wheels, such as vitrified bond diamond grinding wheels and resin bond diamond grinding wheels. These grinding wheels are designed to provide the necessary abrasion and toughness to grind hard and abrasive PCD material effectively. The size and shape of the grinding wheel are also important factors to consider when grinding PCD inserts. Therefore, it is important to select the appropriate grinding wheel for the application to ensure optimal performance and longevity of the PCD insert.
