Montabert HC120 T51-670;Montabert HC120 hydraulic rock drill shank adapter;Shank Adaptor
Used for mine operation, select high quality alloy steel as raw material, through the whole carburizing treatment. Use special CNC machine tool processing equipment and processing process to ensure the tail details, internal and side water hole machining quality. After uniform heat treatment, the brazing tail is straightened with precision instruments to ensure the straightness and anti-manic property of the brazing tail.
The function of the bit tail is to directly bear the impact work and torque of the drill.
The specification and hardness of the bit tail have great influence on the drilling speed, the life of the drill and the drill bit. Therefore, the drill tail should be of appropriate length, with smooth and clean end face, vertical section and axis, and consistent with the drill sleeve of the rock drill (the gap shall not be greater than 0.5mm). Brazing tail hardness to be appropriate, too soft brazing tail life is short, too hard piston is vulnerable to injury, generally brazing tail hardness should be slightly lower than the piston hardness, quenching hardness HRC=38~45 is appropriate.
Drill rod; This kind of shank adaptor is a kind of threaded connecting brazing rod whose nominal diameter of thread is larger than that of hollow steel rod body. In the use of drilling, the weight of the drill rod is reduced, which is conducive to the improvement of drilling efficiency. ProDrill is a professional enterprise engaged in the research and production of rock drill tools. The rock drill tools, subsurface drilling tools and mining machine tools produced by the company are widely used in the fields of basic energy construction such as mountain opening, mining, railway, highway and hydropower.
