Direct type high-speed rotating worktable

Adopting a direct motor with high return speed, it has a speed that is more than 7 times higher than that of a typical rotating worktable.

No reduction gear is required, no thermal displacement occurs, high torque motor is used, high transmission speed, and can be matched with temperature adjustable cooling device.

Using an optical ruler for direct detection, it can achieve high-precision division.

Adopting a full circumference hydraulic locking system, it can achieve high clamping torque.
