Four effective ways to avoid surface burns on the workpiece

Since the cause of burns is high temperature, the main method of avoiding burns is naturally to reduce the generation of heat and accelerate the heat transfer. That is to say, reducing the action time of grinding heat and heat can avoid high temperature and burn on the surface of the workpiece. In production, the main methods to avoid surface burns on the workpiece of the customized metal cutting disc are:
1. Choose the right grinding wheel: the hardness of the abrasive itself is high and the brittleness is better. Such abrasives are not easily blunt during the grinding process, and the abrasive grains after blunt wear are also easily broken to form a new sharp edge, thereby keeping the abrasive grains from cutting the workpiece, instead of rubbing against the workpiece to avoid grinding. A lot of heat is generated. For example, grinding a hardened steel with a white corundum grinding wheel and grinding a hard alloy with a diamond grinding wheel is not easy to burn the workpiece.
2. The use of resin bond grinding wheel is one of the effective measures to reduce burns. The resin binder burns off under the action of the temperature in the grinding zone, and it is not easy to burn the workpiece. For example, in a vertical flat grinding, a resin bond grinding wheel (or sand tile) is used in a high-gloss grinding process using a resin binder and a graphite fine-grained grinding wheel.
3. The use of loose or atmospheric hole grinding wheels, their “self-sharpness” is good, cutting performance is strong, and heat dissipation conditions are good. At the same time, the grinding wheel is also beneficial to the internal cooling method, which greatly reduces the temperature of the grinding area and reduces the risk of burns.
4. Reduce the hardness of the grinding wheel: it can reduce or avoid the burn of the workpiece. Because the hardness of the grinding wheel is too high, that is, the proportion of the bonding agent is large, and the bonding agent itself has no cutting ability, and only causes friction with the workpiece, so that the workpiece generates a large amount of frictional heat.
The 6 inch es cutting disc is made of glass fiber and resin as the reinforced bonding material. It has high tensile strength, impact resistance, and bending strength. It is widely used in the production of ordinary steel, stainless steel metal and non-metal. The excellent materials and exquisite craftsmanship guarantee High cutting efficiency and economical effect of workpieces of different materials.
