2+2 Self-Centering and Compensating Chuck from SMW Autoblok

Wheeling, IL – SMW Autoblok, a world leader in the design and manufacture of rotational chucks, stationary workholding, tooling and custom engineered solutions for the machine tool industry, introduces the versatile four-in-one Centco4 2+2 self-centering and compensating chuck. The Centco4’s superb engineering and flexibility enables it to securely and efficiently clamp virtually any type or shape of geometric part including round, cubic, angular and irregular.

The Centco4 is available in both power and manual models and is ideal for deformation-sensitive workpieces. The 4-jaw Centco4 provides four times less deformation as compared with three-jaw clamping and can be used on all industry-specific machine tools. The ability to handle virtually any part shape means fewer chuck change-outs and vastly reduced downtime. Diverse manual and hydraulic applications include turning, milling, inspection and finishing operations.

“Some of the many Centco4 benefits are that it features two independent self-centering and compensating jaws and single wedge actuation that eliminates the need for a dual-piston cylinder,” said Larry Robbins, president of SMW Autoblok’s Commercial division. “The precision product delivers unlimited flexibility and is perfect for Aerospace and Automotive companies who are looking for one standard chuck that can clamp any part geometry.”  

The drive of the Centco4 moves toward or apart 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. Centrifugal force compensation allows for maximum rotational speeds with up to 210 kn of gripping force with optimized lubrication system that saves both time and money in repairs and maintenance. Four sizes are available in the power version including: 210-52, 260-72, 315-92 and 400-112. A variety of synchron high precision jaws are offered with a 1/16th x 90° interface.
