Resin bonded diamond grinding tools

Resin bonded diamond abrasive tools are made with diamond as abrasive, resin powder as bonding material, and appropriate filling materials. They are made with a certain shape through processes such as preparation, mixing, hot pressing, hardening, and machining. Processing tools that can adapt to different grinding requirements.

Characteristics and uses of resin bonded diamond grinding tools

The grinding processing characteristics of resin bonded diamond grinding tools: good elasticity, high strength, impact resistance, which is beneficial to improving the roughness of the workpiece surface and good surface finish; high grinding efficiency, fast consumption of abrasive tools; self-sharpening during grinding It has good performance, is not easy to block, and has low grinding heat, which can reduce the risk of burning the workpiece. The disadvantages of the grinding process of resin bonded diamond grinding tools: poor wear resistance, not suitable for heavy load grinding. The manufacturing characteristics of resin bonded diamond grinding tools: the production equipment and process flow are relatively simple, hardened at low temperature, the production cycle is short, and it is easier to make grinding tools with complex shapes. Resin bonded diamond grinding tools are used for processing cemented carbide and non-metallic materials, and are mainly used for precision, semi-precision, sharpening, polishing and other processes.

Raw materials for manufacturing resin bonded diamond grinding tools

Raw materials for manufacturing resin bonded diamond grinding tools: abrasives, binders, fillers, wetting agents, release agents and other additives.

2.2.2.1 Abrasives Depending on the processing objects, there are mainly two types of diamond abrasives used to manufacture resin-bonded diamond grinding tools. (1) RVD diamond RVD diamond is a diamond that grows rapidly at a lower temperature. It has many crystal defects and rough surface. Most of them are in the shape of irregular needles. It has low strength, high brittleness and good self-sharpening properties. (2) RVD diamond with metal coating on the surface. The surface of RVD diamond is plated with a layer of nickel, copper, diamond, titanium and other metals or alloys, which can improve the performance of abrasives in the following aspects. - To increase the strength and strength of diamond particles It can be increased by 30% ~60%. The second is to increase the ability to hold the binder. When the grinding hardness is fully combined, the durability of the grinding tool can be increased by 50% to 200% under the same production efficiency. Third, the metal coating acts as a good thermal barrier for diamond particles, preventing oxidation or graphitization, and improving the thermal stability of diamond. However, the self-sharpening properties of RVD diamonds coated with metal coating on the surface will be weakened. After the surface is coated with metal coating, the RVD diamond will increase by 50%~100%.
