Tunnel Boring Machine pick bits

Adopt advanced design method and superior material, optimize the cutting head design , matching design the geometry of cutting head shape, size, cutter tooth arrangement, the geometric parameters and cutting parameters. Strive to work in each equal sectional tooth bearing, same wear-resistance, smooth movement, to improve the efficiency of cutting coal and rock. Reduce tooth wear and tear. To improve the reliability performance.

Description

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.

Application of roadheader cutting teeth
Superior 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.
