| Message: | Xi'an Tydrillbits Co.,Ltd is one of the most famous China tunnel boring machine pick bits manufacturers, welcome to wholesale cheap tunnel boring machine pick bits from our factory.Cutting picks for roadheader Cut the warm extrusion technology manufacturing tooth body, warm extrusion is in metallic recrystallization temperature of material forming, molding temperature from 600 to 800 degrees Celsius. In this temperature range, the metal is no longer produce the defects such as oxidation and the grain growth, improve the microstructure, fine grains, increase the impact toughness of the cutting teeth. At the top of the cobalt cemented carbide carbide and synthesis, formed is very high hardness and wear resistance of the alloy, the use of advanced welding technology, to ensure the high performance-to-price ratio of the cutting teeth.Specification of roadheader cutting teethModel sizePick length(mm)Length of head(mm)Pick handle diameter(mm)Pick collar diameter(mm)Carbide insert diameter(mm)U47-1930CP13863305019U47-2335CP14065305023S120-1628CP14368305516S120-1930CP14368305519U135-1930CP15580386319U135-2232CP15580386322U135-2437CP15580386324We accept customized order, customer provides parameter or drawings, we design and manufacture as customer’s requirements.Application of roadheader cutting teethSuperior raw material and process make the cutting picks have a impact toughness and effective to be against the corrosive working conditions. They are widely used in roadway drivage of coal lane and soft rock, also used in tunnel construction of railway, highway and water conservancy projects. Cutting picks always use with roadheader. url:http://www.tydrillbits.com |
