Coal cutters are vulnerable parts of mining machinery. Through long-term analysis and research on coal cutters, the company has analyzed their reliability from several aspects, including the selection of new coal cutters, cutter arrangement, and cutter structure improvement. Improve the reliability of coal cutting teeth, reduce the proportion of tooth consumption in the cost per ton of coal, and increase the effective working time of coal mining machines. CNC lathe machining ensures consistent dimensions. Adopting a special heat treatment process, reaching 40-45 degrees, with no oxidation on the surface. The cutting head adopts isothermal quenching process, and the hardness does not decrease. The hard alloy adopts YG11C produced by domestic formal factories, with stable quality. Especially the pure alloy used around the alloy blade tip provides protection. The hardness reaches 65 degrees or above. Compared with traditional coal cutters, it has the following advantages: 1. Long service life, 4-5 times that of traditional cutters. 2. High work efficiency: 2.5 times that of old-fashioned cutters. 3. Good energy-saving efficiency: Due to a significant reduction in replacement frequency, the downtime of the machine has been shortened, reducing work costs.
