The pick-shaped cutter of Coal mining machine and development machine is a very important component, whose service life and cutting efficiency directly influence the digging efficiency. teeth loss and crack of hard alloy head is the main reason for liquidation of pick cutter, besides the abrasion and break-off. Our company has made a great achievement in solving the crack and fall-off of hard alloy head after large numbers of researches and experiments. The process method of wear-resisting anti-falloff pick-shaped cutter is authorized and awarded the certificate of invention patent by State Intellectual Property Office. The Igood brand series pick cutter, produced by our company, adopts special anti-falloff methods and unique heat treatment crafts by means of the technology of low temperature welding, avoiding the decrease of performance caused by twice heating in high temperature, simultaneously strengthening the combining power of tooth head and body, keeping the original performance of hard alloy head in maximum limit, enhancing the comprehensive mechanical performance, effectively preventing the crack and fall-off of tooth head.
