Tunnel engineering products are aimed at the excavation and support needs under complex geology. The cutter head of the shield machine is equipped with hob and scraper to adapt to earth pressure balance or full-section excavation of hard rock tunnels; the rock drilling rig is equipped with hydraulic rock drilling tools for precise drilling of blast holes in railway tunnels.
Application
Various cutting cutters are developed and produced using high-quality cemented carbide produced by internationally renowned companies and combined with high-quality steel substrates to meet the domestic and foreign needs for construction conditions such as coal mines.
