The cutting disc is made of resin as a binder, glass fiber mesh as an auxiliary material, and a variety of materials. Especially for hard-to-cut materials like alloy steel and stainless steel. Dry and wet cutting methods make the cutting precision more stable. At the same time, the selection of cutting material and hardness improves cutting efficiency and reduces production costs. However, personal burn accidents also occur during the cutting process.
The question now is how to avoid burns during cutting, which will affect the cutting efficiency too low.
First, whether the hardness of the selected cutting disc is too high or too low. If it is too high, a burnt metallographic structure will occur. And the microstructure of the material cannot be accurately tested. resulting in errors. If the hardness is too low, the cutting efficiency will be too low and the cutting discs will be wasted. To make the cutting process non-burning and sharp, it is only necessary to test the hardness of the material and use the coolant correctly.
The second is to choose the raw material of the cutting board. Alumina is the first choice for cutting metal materials. Silicon carbide is the first choice for cutting non-ferrous and non-metallic materials. Because the alumina material used to cut metal materials does not chemically react with the chemical components in the metal. Therefore, the chemical activity that is conducive to cutting non-metals and non-metals is very small. The chemical activity of silicon carbide material is less than that of alumina. Good cutting performance, small burnout and wear, etc.
Also, choosing the right particle size is good for cutting. If sharpness is required, a coarser granularity can be selected. If the cutting requires high precision, a relatively fine-grained abrasive should be selected.
In short, all the problems encountered during the cutting process. All need to be determined according to the hardness and material of the sample. When choosing a cutting disc, the material of the cutting blade should be selected in a targeted manner. The material suitable for the factory is the best.
