SMW Autoblok's newest air chuck design is the BIG BORE BB-EXL-SC2G. This front-end spring clamp power chuck features an extra long jaw stroke of 1.5 inches, as well as increased safety monitoring to keep up with the changing demands of the oil and gas industries.
For optimal productivity and efficiency, the BB-EXL-SC2G utilizes spring clamping and pneumatic unclamping, cutting costs with lower air consumption, according to the company. To expedite the setup process, this air chuck has a step mode for partial opening and clamping when shimming. As a self-centering chuck, it has an open and clamp time of less than three seconds.
Available with the optional control unit, the stroke control of the BB-EXL-SC2G monitors both the pressure and stroke to ensure that pipes stay in place and won't allow the jaw to move if the pressure is too low.
To maintain the increased up time, the BB-EXL-SC2G is Proofline sealed for low maintenance. The permanent grease lubrication helps the chuck retain constant grip force for more efficient turning.

chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- turning
turning
Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
