Problems solved by technology

[0003] Grinding wheels are mostly used in the actual cutting process. The main performance indicators to measure the grinding wheel include whether the strength is high, whether it is wear-resistant, and whether it is corrosion-resistant. The current technology can basically solve the problem of corrosion resistance, but in terms of strength and durability However, there is a big problem in abrasiveness, which leads to short service life of the grinding wheel and affects the cutting effect. To solve the problem of strength and wear resistance of the grinding wheel, it is not only necessary to start from its raw material formula, but more importantly, to carry out its production process. Improvement, as well as various equipment used in the production process, are the direct factors affecting the performance of the grinding wheel, and according to the existing diamond production process, there are still many aspects that need to be improved

Abstract

The invention discloses an abrasion-resistant S-shaped grinding wheel and a hot-press forming technology thereof. The abrasion-resistant S-shaped grinding wheel comprises the following main materials in volume fraction: 12 to 15% of diamond, 20 to 25% of copper, 40 to 45% of iron, 3 to 8% of tin, 5 to 8% of nickel, 5 to 8% of cobalt and 3 to 5% of auxiliary material alloy powder. The continuous tooth S-shaped grinding wheel is produced through the steps of batching, premixing, total mixing, cold pressing performing, hot pressing sintering, primary cooling, high frequency welding, secondary cooling, surface treatment, paint spraying, edging, and the like. According to the S-shaped grinding wheel produced through the formula and the technology, the strength is improved, the abrasion resistance is improved as well, the service life is prolonged in the actual use process, the production cost is greatly reduced, the resources are saved, and the technology is environment-friendly, sanitary and safe in the production process.

Description

technical field [0001] The invention relates to a grinding wheel, in particular to a wear-resistant S-shaped grinding wheel and its hot-pressing forming process. Background technique [0002] Grinding wheel is a cutting tool, which is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics. The grinding wheel is mainly composed of two parts; the base body and the cutter head. The substrate is the main supporting part of the bonded cutter head, while the cutter head is the part that cuts during use. The cutter head will be continuously consumed during use, but the substrate will not. The reason why the cutter head can cut The role of diamond is because it contains diamond, which is currently the hardest substance, and it rubs and cuts the processed object in the cutter head. The diamond particles are wrapped in metal inside the cutter head. [0003] Grinding wheels are mostly used in the actual cutting process...
