How to choose the appropriate size of diamond grinding head according to the grinding object? | |
1. Selection of coarse-grained diamond grinding head When the grinding object is a material with high hardness and large allowance, a coarse-grained diamond grinding head is usually the first choice. For example, when processing large carbide molds or stone rough materials, large material removal is the main feature. At this time, it is more appropriate to choose a diamond grinding head with a particle size of about 60-120 mesh. Coarse-grained diamond grinding heads are like large "cutting tools" with a large cutting depth and high material removal rate during the grinding process. The reason is that the contact area between coarse-grained diamonds and the grinding object is relatively large, and materials can be removed more quickly under the same pressure and speed. Moreover, for materials with high hardness, coarse-grained particles can better withstand the impact force during the grinding process, avoid premature breakage of diamonds, and thus ensure grinding efficiency. 2. Application scenarios of medium-grained diamond grinding heads For some grinding objects with medium hardness and high precision requirements, medium-grained diamond grinding heads are a suitable choice. For example, in the field of metal processing, when ordinary steel or aluminum alloy is ground with medium precision, a diamond grinding head with a particle size of 120-230 mesh is more suitable. In this case, the hardness and precision requirements of the material require a balanced grinding effect. Medium-sized particles can not only ensure a certain material removal rate, but also better control the roughness of the grinding surface. Its moderate particle size generates relatively small cutting forces during the grinding process, which is conducive to obtaining more precise size and shape accuracy, and can also reduce the wear of the grinding equipment. 3. Considerations for fine-grained diamond grinding heads When the grinding object is a material with low hardness but extremely high surface quality requirements, a fine-grained diamond grinding head is the key. In the fine grinding of optical lenses, ceramics or precision molds, diamond grinding heads with a particle size of 230-600 mesh or even finer are widely used. Since these grinding objects have strict requirements on surface roughness and shape accuracy, fine-grained diamond grinding heads can produce tiny cutting marks on the material surface. They can grind at a lower cutting depth to obtain a high-quality surface. For example, in the grinding of optical lenses, fine-grained diamond grinding heads can control the roughness of the lens surface at the nanometer level to meet the requirements of optical performance. 4. Particle size selection for special grinding objects For some special grinding objects, such as superhard material coatings or composite materials, the particle size selection needs to consider multiple factors comprehensively. In the case of superhard material coatings, the coating itself has an extremely high hardness, but the substrate material under the coating may have a lower hardness. At this time, you can first use a coarse-grained diamond grinding head to quickly remove the excess part of the coating, and then use fine-grained particles to finely grind the junction of the coating and the substrate to ensure the surface quality. For composite materials, the hardness and grinding characteristics of their different components vary greatly. In this case, a multi-level diamond grinding head may be required. For example, for metal-based ceramic composite materials, the metal substrate part can be ground with medium-grained particles first, and then the ceramic part can be ground with fine-grained particles to achieve the best grinding effect. | |
