In the field of surface processing of hard materials, grinding curved and irregular shaped parts has always been a challenging task. This article delves into the influence of the design form of diamond grinding discs on edge stability, and combines the technical advantages of the brazed diamond grinding discs of Henan UHD Superhard Tools Co., Ltd. (UHD) to provide practical selection guides and application techniques.
When selecting diamond grinding discs, several key factors need to be considered. Firstly, the diameter of the grinding disc is crucial. Generally, for large - area grinding, a larger - diameter grinding disc (e.g., 200 - 300mm) can improve efficiency, while for detailed processing of small - sized parts, a smaller - diameter grinding disc (e.g., 50 - 100mm) is more appropriate.
The particle size of diamonds also plays a vital role. Coarser diamond particles (e.g., 30 - 60 mesh) are suitable for rough grinding with high material removal rates, while finer particles (e.g., 120 - 200 mesh) are used for finishing to achieve a smoother surface finish.
The choice of bonding agent is another important aspect. Different bonding agents have different properties. For example, metal bonding agents offer high strength and good wear resistance, which are suitable for high - load grinding operations. Resin bonding agents, on the other hand, provide better self - sharpening performance and are often used for precision grinding.
UHD's diamond grinding discs show excellent performance on various hard materials. When grinding gray cast iron, the flat grinding discs can achieve a material removal rate of up to 50 - 80 cubic centimeters per minute, and the surface roughness can reach Ra 1.6 - 3.2μm. For stainless steel, the curved grinding discs can effectively reduce the occurrence of grinding burns and improve the surface quality. In the case of stone materials, the anti - impact performance of UHD's grinding discs ensures long - term stable operation, with a service life that can be 2 - 3 times longer than ordinary grinding discs.
A manufacturing company was facing the problem of low grinding efficiency and premature wear of grinding discs when processing curved parts made of high - strength steel. After adopting UHD's customized brazed diamond grinding discs, the grinding efficiency increased by 30%, and the service life of the grinding discs was extended by 40%. This case clearly demonstrates the effectiveness of UHD's products in solving practical problems.
To help readers better select the appropriate diamond grinding discs, we provide a selection checklist and a particle size recommendation table:
| Material | Recommended Grinding Disc Type | Recommended Particle Size |
|---|---|---|
| Gray Cast Iron | Flat Grinding Disc | 30 - 60 mesh |
| Stainless Steel | Curved Grinding Disc | 60 - 120 mesh |
| Stone | Flat or Curved Grinding Disc | 40 - 80 mesh |
