Product Description

The high-pressure hydraulic cutting punching machine is mainly used for hydraulic cutting and cavity making technology during underground drilling construction in coal mines, achieving the purpose of gas drainage and coal seam pressure relief. When drilling normally, if the water pressure is lower than the opening pressure, the cooling water required for the drill bit is provided, and the nozzle does not spray water. When the water pressure reaches the opening pressure of the punching machine, the punching machine works, and the high-pressure water is sprayed out by the nozzle to cut the coal seam. Combined with the rotation of the drill pipe, the coal seam is cut and drilled. The punching machine series products have a compact and reasonable structure, and use high wear-resistant sealing components for a longer service life.
