氣缸內置，驅動力通過斜楔機構傳遞。工作穩定可靠。在加工期間，卡盤通過雙作用單向閥保持壓力。只有在主軸停止時，壓縮空氣才能通過配氣盤和配氣圈供給。

Chuck with built-in cylinder, driving force is transmitted through the wedge mechanism. It is stable and reliable in work. Built in double non-return valves maintain the air pressure during machining. The compressed air feed via distributor ring and profile seals only when the spindle completely stops.

配氣盤的安裝和定心調整通過固定于主軸箱端面的配氣盤支架實現，保證與旋轉的卡盤不存在任何接觸。為提高操作安全，可根據用戶要求增加壓力和夾緊行程監控裝置。

The stationary distributor ring must be mounted so that no contact exist against the rotating power chuck. The distributor ring is centered and laterally mounted by means of a bracket fixed to the headstock of the lathe. To ensure the safety, a safety control system supplied according to the customer’s request, so that clamping pressure level constantly checked.
