SMW Autoblok's Centco4 Chuck Centers, Compensates for Various Geometries
SMW Autoblok’s Centco4 2+2 self-centering and compensating chuck can clamp round, cubic, angular, irregular and other geometric workpieces.
SMW Autoblok’s Centco4 2+2 self-centering and compensating chuck can clamp round, cubic, angular, irregular and other geometric workpieces. Said to be ideal for deformation-sensitive workpieces, the Centco4 is available in both powered and manual models. The four-jawed chuck reduces deformation fourfold compared to three-jaw clamping and can be used on all industry-specific machine tools, the company says. The ability to handle virtually any part shape means fewer chuck change-outs and reduced downtime. Manual and hydraulic applications include turning, milling, inspection and finishing operations.
The Centco4 features two independent self-centering and compensating jaws as well as single-wedge actuation that eliminates the need for a dual-piston cylinder.
The chuck’s drive moves on two parallel axes and needs only one standard-stroke, single-piston cylinder for actuation. This allows for independent, self-centering clamping via both axes, the company says. Centrifugal force compensation allows for high rotational speeds with up to 210 kN of gripping force. A variety of Synchron high-precision jaws are offered with a 1/16th × 90-degree interface.

Don't assume the standard chuck is the right workholding for every lathe application.
These vise jaws use protruding, mechanical pins to repeatedly support workpieces either horizontally or at angles. They are said to allow quicker setups than conventional parallels.
