The front part of the main shaft adopts the patented multi-layer labyrinth seal design and air-tight design. The stator coil inside the main shaft is sealed by “glue injection”, which isolates the external coolant and makes the electric spindle have a longer service life. The stator of the electric spindle is cooled by a water cooler to ensure stable operation of the electric spindle under long-term and high-temperature conditions. The main shaft adopts nitriding treatment to improve the service life, and the main shaft and the rotor are dynamically balanced according to the G0.4 standard, thereby ensuring the stability of high-speed machining. The broaching mechanism of the spindle is tensioned by the German brand disc spring, which is more than 8 times longer than that of other manufacturers. The claw is made of steel ball tensioning sleeve structure, compared with the split claws used by other manufacturers. Strong anti-dust ability, simple structure and low failure rate.
