The fully sealed MM e-motion 4-jaw chuck provides contact-free adjustment of gripping force without unclamping parts during every phase of production. Each jaw is independently controlled and monitored by an individual electro-mechanical drive, allowing clamping functions such as self-centering, compensating, and individual jaw movement.
Designed for mill-turn applications and horizontal/vertical lathes, the MM e-motion supports heavy-duty precision machining of easily deformed workpieces. It provides an automatic center adjustment for any workpiece shape or configuration including round, square, rectangular, and irregular shapes in addition to workpieces with different wall thicknesses.
A lightweight version (MM e-motion LW) is designed for mill-turn operations with limited load bearing capacity on the spindle. The LW functions the same as the standard MM e-motion yet allows for heavier workpieces and more usable Z stroke.
The chuck body and internal parts are case hardened for increased life, rigidity, precision, and durability. The power chuck accepts inch-serrated top jaws and is available from 500mm to 1,250mm.
Industry 4.0 data flows from permanent monitoring of grip force and jaw position, information that can be stored and recalled for process repeatability. Data interchanges easily between different machines in the same facility or at other locations worldwide.
The MM e-motion uses the F280 wireless inductive radial coupler system to transmit energy and data contact-free through a 3mm air gap between rotating and stationary components. The IP67 rated inductive coupler system includes a stationary coupler and a movable mobile coupler. The stationary coupler is incorporated into the machine or setup station, and the mobile coupler is incorporated on the pallet side. The system can transmit up to 1,500W between the stationary and mobile couplers, and two CAN bus channels and two digital signals can be transmitted.
