Twin-Hammer Impact Mechanism |
|||
Spindle. It is made of high-strength nickel-molybdenum alloy which is hardened by carburizing and quenching and processed through precision CNC with high hardness and high precision to ensure a more stable blow torque. |
Rotor. Its material is from special alloy structural steel. It comes with professional heat treatment and high-precision CNC processing and provides impact fatigue resistance and high precision. |
||
Ring. It comes from low-carbon chromium-nickel-molybdenum alloy and has carburizing and quenching heat treatment with stronger impact resistance and wear resistance. |
Bearing. It is constructed with industrial-grade deep groove ball bearings with smooth rotation, wear resistance, impact resistance and long service life. |
||
Cylinder. It features high density powder metallurgy manufacturing and vacuum quenching oil immersion treatment with precise grinding, high precision and smooth working surface, making the motor output more powerful. |
Blades. They are made of new materials so that the breaking strength is increased by 50%, the thermal stability is increased by 80% and the wear resistance is good. |
