Automatic electric chuck, claw DC motor drive. The clamping motor current is sensitive, adjustable and stable. The clamping range is wider and clamping force is larger. Non - destructive pipe clamping, fast automatic centering and clamping pipe, performance is more stable. The chuck size is smaller, rotation inertia is low, and dynamic performance is strong. Self-centering electric chuck, gear transmission mode, higher transmission efficiency, long working life and high work reliability.The maximum cutting diameter of T series is 30% longer than the mainstream products in the market,The maximum cutting weight is 100% heavier than the mainstream products in the market.
