  • High Accuracy Chucks: Repeatable Results for Quality Parts

    Quality turning results are never “one and done.” Precision on the production line requires workholding that can maintain a high level of accuracy job after job. Most industries (and especially those like aerospace, automotive and OCTG) now demand chucks with built-in “repeatability.” In this article, we’ll look at some of our products that rate at the top end on the accuracy scale.

    Whenever there is an application that requires enhanced centering accuracy and concentricity, consistent clamping force or centering accuracy for secondary operations, the diaphragm chuck is the ideal solution.

    Unlike standard chucks that rely on the wedge and master jaw linkage for clamping, the diaphragm chuck relies on elastic deformation; expanding, contracting and using resistance to hold work pieces in place. With the absence of sliding parts, the diaphragm chuck needs no lubrication, and offers a more consistent grip force, time after time, accurately repeating within 10 microns.

    Giving super high-precision turning, grinding or milling operations a superior final finish, the D-Plus Diaphragm Chuck is ideal for shaft type work pieces, such as input and output shafts, where sub-micron accuracy is mandatory.

    The D-VARIO is a quick jaw change diaphragm chuck specifically made for the grinding of gears. Speed is not achieved at the expense of quality, though. Micrometer fine adjustment of the centerline makes high precision grinding possible.

    Subtle variations can make a big difference when you are clamping workpieces with a high demand for parallelism (the minimum degree of variance parallel to an origin point).

    For exceptional parallelism and productivity, our TX Series chucks are top of the line. The TX-RV (quick jaw change) and the TX-C (tongue and grove) are high precision pull-down chucks with a rigid 3-jaw design, providing excellent repeatability within 12 microns.

    The TX Series is ideal for inner diameter (ID) and outer diameter (OD) clamping, offering optimal stability and centrifugal force compensation. With active pull-down, a function only offered by SMW Autoblok, these chucks perform three operations. The pre-clamping function centralizes the chuck, the work piece is then pulled down onto locators, and finally it is clamped firmly into place.

    The TX Series comes fully sealed as part of our Proofline Series of chucks, greatly reducing overall maintenance versus the competition. Plus, the permanent lubrication offered by these oil filled chucks helps maintain consistent grip force shift after shift.

    Here at SMW Autoblok, we don’t settle for just being close. We hold precision to the highest standard, ensuring that all of our chucks turn with microns in mind. To round out our list of highly accurate offerings, we present the AcuGrind High Precision Air Chuck.

    With a built-in pneumatic actuating cylinder, the AcuGrind is ideal for tight tolerance turning and grinding applications. We take the stress out of manufacturing high precision parts for the automotive and medical industries by providing accuracy to +/- 2 microns, shaping ultra-reliable parts in every cycle.

    The AcuGrind can perform both ID and OD clamping applications utilizing a boring ring and pin. Its case-hardened base jaws allow for extra rigidity and repeatability within 2 microns. If you’re looking for a chuck to handle your most precise finishing, the AcuGrind is the perfect choice.

    There are enough variables in a machine shop that affect quality results, from tool life to the ambient temperature. The performance of our high accuracy chucks is one of the few constants you can always depend on. If you would like to discuss your particular needs, please contact us.
