Description

I 4.120 Hydraulic Vises, Concentric Clamping

Application
Hydraulic vises, also called fixture clamps, are used for machining of dimensionally stable workpieces in single or multiple clamping fixtures. Due to their compact design they can be arranged in a very limited space.
Hydraulic vises are especially suitable for series manufacturing in automated mode.
The double-acting cylinder function combined with central lubrication and good swarf protection guarantees high process safety.

Description
The hydraulic vise with a concentric clamping function consists of a very slim basic body with 2 integrated hydraulic cylinders. The piston forces are transferred via a guided connecting link to the two clamping slides so that a centric synchronism is obtained.
All threads and ports are at the bottom to enable a space-saving arrangement of several clamping points in a very limited space. If fixing from below is not possible, an adaptor plate for manifold mounting or tube connection is available.
Blanks of clamping jaws that can be adapted to the workpiece contour are also available as an accessory.

Important notes
The concentric clamping vise is only suitable for exterior clamping.
Lubricate at the latest after 500 clamping cycles the clamping slide via the central lubrication. Never use the complete clamping stroke to guarantee safe clamping of the workpiece.

Max. operating temperature 80 °C
