1FF1/10° 150*20T*25.4*5mm D400 C100 Resin Bond Diamond Grinding Wheel For Grinding Carbon Brush

Product Description:

Resin diamond grinding wheel is a grinding tool made of diamond as abrasive and resin as a binder. It has the characteristics of excellent self-sharpening, high grinding efficiency and good heat dissipation. It is mainly used for fine grinding and polishing of high hardness materials such as cemented carbide, ceramics, optical glass, semiconductor materials, etc. Its preparation process uses low-temperature curing technology to achieve complex shape molding, and improves wear resistance and sharpness by optimizing the directional arrangement of abrasives and the ratio of binders [1]. This grinding wheel has significant advantages in the fields of tool sharpening, hard and brittle material cutting, etc.

Resin-bonded diamond grinding wheels offer exceptionally high surface finish quality. Thanks to their excellent self-sharpening properties and the inherent elasticity of the resin bond, they effectively absorb grinding vibrations, resulting in extremely low surface roughness (Ra),  preventing surface damage such as burns and micro-cracks on the workpiece, and ensuring perfect machining integrity.

  Resin-bonded diamond grinding wheels also offer the advantages of low grinding forces and temperatures. Their sharp cutting characteristics reduce grinding resistance and energy consumption. Combined with coolant, they effectively control the temperature of the grinding zone, making them particularly suitable for machining heat-sensitive materials.

Resin-bonded diamond grinding wheels offer a wide range of adaptability: by adjusting the diamond concentration, grit size, resin formulation, and additives, they can be customized to meet a wide range of processing requirements, from rough grinding to mirror polishing.Resin-bonded diamond grinding wheels also offer excellent economic benefits: while the cost per wheel may be lower than that of metal-bonded grinding wheels, their true advantage lies in the reduced overall cost per part, resulting from their high material removal rate and excellent surface quality.

Features:

• Extremely High Hardness: Diamond is the hardest substance in nature, making it highly efficient and long-lasting for grinding non-metallic materials like carbon brushes. Even brushes containing copper powder can be easily polished with diamond.
• Sharp and wear-resistant: can maintain sharpness for a long time and reduce frequent trimming.
• Good elasticity and strong self-sharpening properties: The resin bond has a certain elasticity that can cushion the impact force during grinding and effectively reduce the edge collapse of the carbon brush. At the same time, dull abrasive particles are easily shed, revealing new sharp abrasive particles (self-sharpening), ensuring stable grinding performance.
• Good polishing effect: Resin grinding wheels can produce a higher surface finish than metal or ceramic bonds, which is critical for the fit of carbon brushes to the commutator.
• Low grinding temperature: helps prevent the resin bond itself from burning due to overheating, and also avoids changes in the carbon brush surface due to high temperature.

Applications:

Diamond resin-bonded grinding wheels are grinding tools made with diamond as the abrasive and resin as the binder. They feature excellent self-sharpening properties, high grinding efficiency, and good heat dissipation. They are primarily used for fine grinding and polishing of high-hardness materials such as cemented carbide, ceramics, optical glass, and semiconductor materials. Their manufacturing process utilizes low-temperature curing technology to achieve complex shapes, while optimizing the abrasive orientation and binder ratio to enhance wear resistance and sharpness. These grinding wheels offer significant advantages in tool sharpening and cutting hard and brittle materials.
