Pneumatic and Hydraulic Twin Vices – Aerospace Manufacturing and Design



SMW automatic blocking, a global leader in the design and manufacture of rotary chucks, stationary clamps, tooling and custom engineering solutions for the machine tool industry, introduces the fully automated compact double vise PTP / PTH Providing pneumatic and hydraulic clamping force with standard jaw stroke, long stroke or fixed jaw stroke control.

Ideal for automation, the self-centering pneumatic PTP and hydraulic PTH double vices are the perfect solution for storage and warehousing solutions as well as 4 and 5 axis multi-pallet machining centers with or without robotic loading. .

The PTP / PTH twin vices feature a compact design, high fail-safe clamping force of up to 60kN, case-hardened components for high precision and long life. Effective for both OD and ID clamping, spring loaded twin vices and can be used with standard or engineered top jaws. Optional SinterGrip clamping inserts are available which provide no dovetail and a clamping depth of 3.5mm (vs. 30mm standard). The addition of SinterGrip reduces the waste of expensive raw materials and minimizes warping. A series of toothed solid carbide inserts grip the workpiece so firmly that vibrations are virtually nonexistent. This stability allows for higher cutting speed and feed rates, which translates to more metal removed in less machining time.

All modules are corrosion protected Proofline sealed and have a built-in air purification function to ensure that the bearing surface of the clamping system remains clean and free of chips during changeover or automation. This feature dramatically reduces maintenance and production time and offers repeat accuracy of up to 0.01mm. Sizes include 100mm, 120mm, 160mm, and 200mm.
