In the process of using the cutting blade, the cutting blade is made of resin as a binder, glass fiber mesh as an auxiliary material, and a variety of materials, especially for materials that are difficult to cut such as alloy steel and stainless steel. The dry and wet cutting methods make the cutting accuracy more stable. At the same time, the choice of cutting material and hardness improves cutting efficiency and reduces production costs. However, personal burn accidents may also occur during the cutting process.
The problem now is how to avoid burns during the cutting process, which will affect the cutting efficiency too low.
1. First of all, no matter whether the hardness of the selected cutting part is too high or too low, if it is too high, a burned 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 cut pieces will be wasted. To make the cutting process non-burning and sharp, only need to test the hardness of the material and use the coolant correctly.
2. The second is to choose raw materials for cutting plates. Alumina is the first choice for cutting metal materials, and silicon carbide is the first choice for cutting non-ferrous and non-metallic materials. Because the aluminum oxide material used for cutting metal materials will not chemically react with the chemical components in the metal, it is helpful to cut non-metal and non-metal chemical activity is small, the chemical activity of silicon carbide material is lower than that of aluminum oxide, and the cutting performance Good, low burn and wear.
3. Similarly, choosing a suitable particle size is beneficial to cutting. If sharpness is required, a coarser particle size can be selected. If cutting requires high precision, an abrasive with a relatively fine particle size should be selected.
In short, all the problems encountered in the cutting process need to be determined first according to the hardness and material of the sample. When choosing the cutting blade, the material of the cutting blade should be selected in a targeted manner, and the material suitable for the factory is the best.
