Sealed, Spring-Loaded Twin Vises from SMW Autoblok

SMW Autoblok introduces the fully automated, compact PTP/PTH series twin vises, which provide pneumatic and hydraulic clamping force with standard jaw stroke, long stroke or fixed jaw stroke control.

SMW Autoblok says the vises are ideal for automation; the self-centering PTP pneumatic and PTH hydraulic twin vises work with tombstone and storage solutions, as well as four- and five-axis multi-pallet machining centers — with or without robot loading.

The PTP/PTH twin vises reportedly feature a compact design, high failsafe clamping force up to 60 kN and case-hardened components for high precision and long life. Effective for both O.D. and I.D clamping, the spring-loaded twin vises can be used with industry standard or engineered top jaws.

In addition, optional SinterGrip clamping inserts are available, which provide no dovetailing and 3.5 mm clamping depth (versus 30 mm standard). SMW Autoblok claims that adding SinterGrip reduces the waste of expensive raw materials and minimizes deformation. A series of solid carbide serrated inserts reportedly grip the workpiece so securely that vibration is virtually non-existent. This stability allows for higher cutting speed and feed rates, translating to more metal removed in less machining time.

All modules are sealed and protected against corrosion and feature a built-in air cleaning function to ensure that the clamping system's support surface remain clean and free of chips during changeover or automation. According to SMW Autoblok, this feature greatly reduces maintenance and production time and provides a repeat accuracy of up to 0.01 mm. Sizes include 100, 120, 160 and 200 mm.
