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. Model: U135 U170 cutter cutter cutter U47 U94 U95 cutter cutter cutter U84 U92 pick cutter S120 S100 S160 cutter cutter cutter Q7. Our products are oriented Henan cutter, cutter sales in Shanxi, Shanxi, Shandong cutter cutter Direct Direct Direct Inner Mongolia, Hunan cutter cutter direct marketing and other parts of the country. Mine is a mining pick and tunneling machinery wear parts, one is off the main tool for coal and coal crusher, its performance directly affects the ability to play mining machinery production, power consumption, smooth and other related parts of life. Many different types of picks, general structure is quenched, tempered low alloy steel body inlaid carbide blades. Cutter at work withstand high cyclic stress, shear stress, shock loading. The main failure mode heads off, chipping knives and blades, blade wear, under certain working conditions are often caused because of broken cutter blade failure. Since the mechanical cutter blade cutter performance directly affects the life, so choose a reasonable cut-off cutter body material and effective heat treatment, to reduce the wear cutter blade broken, reducing consumption shearer , improving the operation of mining machinery, increase overall economic efficiency of coal production, have a positive meaning. Cutter when cutting coal withstand high cyclic compressive stress, shear stress and shock loading, though the hardness of coal is high, but often encounter ore gangue and other hard materials, coal and rock cutting process due to friction , the impact will result in cutting tooth temperature, in such a complex work under working conditions cutter, cutter body requires both its wear and should have good impact resistance. Cutter blade generally use low-alloy structural steel.
