Henan Coal Mining Machinery Co., Ltd. is a Sino-American national production drilling of professional production company, is the country's largest production base of non-sparking. Founded in 1976. After decades of development, the company has Henan Shen Qiu Lianchi industrial parks and industrial areas of Anhui Yingshang two production bases. Existing staff 510 people, 20 senior engineers, 46 technicians, the company annual output value of 10 billion yuan, profits of 150 million yuan, won the government and society's recognition and praise. Supply wear non-sparking type cutter cutter cutter cutter gear sleeve wear reinforced auger cutter cutter cutter spark mining pick the company's coal cutter, gear sets, tooth Block, U47, U765, U76, U82, U84, U85, U92, U94, U95, U119, U138, S100, S120, S150, S160, S170, 75C, B47K22, 3050, C31HD, C21HD, 13 #, 23 #, 55 # and other specifications Model complete, high strength, wear resistance and long life. This product is heat-treated steel body use high-strength alloy steel, shaped to maintain a high toughness and high wear resistance; heads through hot isostatic selection of high quality carbide. Widely used in a variety of mechanized mining machine, mechanized excavation machines, continuous mining machine. According to the different rock, half coal production performance of different design cutter, to meet different needs of customers. While the design, production, maintenance boring cannon head, shearer drum. Cutter is wearing parts of mining machinery, the company picks through long-term analysis and research, from the selection of the new cutter, cutter cutter layout and structural improvements, and several other aspects of the cross-sectional analysis of the reliability of the teeth. Cut teeth improve reliability, reduce the cost of the tooth coal consumption representing the proportion of effective working time to improve shearer. Cutter using a special heat treatment process, up to 40-45 degrees, coal pick almost no surface oxidation. Cutter head using isothermal quenching, the hardness is not reduced. The use of domestic coal cutter carbide regular large production, quality and stability. According to customer needs plus welding wear layer, coal cutter tooth hardness of 65 degrees or more, but also like to customize my factory cutter body is made of 42CrMo steel CNC lathe machine processing, to ensure the same size, hardness after heat treatment up to 40 degrees, tooth head isothermal quenching, carbide using regular domestic manufacturers products, quality and stability. There are belt wear layer and without wear layer two optional. The company produces coal cutter, gear sets, tooth Block, U47, U765, U76, U82, U84, U85, U92, U94, U95, U119, U138, S100, S120, S150, S160, S170, 75C, B47K22, 3050, C31HD, C21HD, 13 #, 23 #, 55 #, etc. complete model specifications, high strength, wear resistance and long life. This product is heat-treated steel body use high-strength alloy steel, shaped to maintain a high toughness and high wear resistance; heads through hot isostatic selection of high quality carbide.
