The swing arm lifting system is controlled by an electronic timer. When the button is activated, the swing arm can be automatically relaxed and lifted vertically, or the lift is stopped and automatically clamped. It is easy to operate and can maintain the original tool center position after tool change. Special oil circulation pump with built-in gear to cool the precision gear in the gear box can reduce excessive gear wear. The friction clutch can absorb the longitudinal impact force generated by the main shaft, so it can effectively protect all the transmission components in the gear box, and has a quick return function of the main shaft, which can speed up the tapping operation speed.
