SMW Autoblok has introduced its fully sealed MM e-motion four-jaw chuck, providing contact-free adjustment of the gripping force without unclamping parts during every phase of the production process.

An individual electro-mechanical drive independently controls and monitors each jaw of the MM e-motion. This capability allows for many clamping functions, including self-centring, compensating and individual jaw movement, all within one fully automated chuck.

Suitable for mill-turn applications, horizontal and vertical lathes, the MM e-motion facilitates the heavy-duty precision machining of easily deformed workpieces and provides an automatic centre adjustment for any workpiece shape or configuration, including round, square, rectangular and irregular shapes, as well as workpieces with different wall thicknesses. Also available is a lightweight (LW) version for when mill-turn load-bearing capacity on the spindle is limited. LW versions feature the same functionality as the standard MM e-motion yet allow for higher workpiece weight and more usable Z stroke.

The chuck body and internal parts are case-hardened for increased chuck life, as well as rigidity, precision and durability. This specialty power chuck accepts imperial serrated top jaws and is available in sizes from 500-1250 mm.

Suitable for Industry 4.0, permanent monitoring of the grip force and jaw positions can be stored and recalled for when the process needs repeating. As a result, digital data is easily interchanged between different machines in the same production facility or at other facilities worldwide.

SMW Autoblok’s MM e-motion uses the newly developed F280 wireless inductive radial coupler system that transmits energy and data contact-free through an air gap of approximately 3 mm between rotating and stationary components.
