Fresmak Arnold vice log Classic Hydraulic Models

The classic design with base for direct clamping to the machine table or to the optional rotary base.
The automatic version of the classic vice is most often configured on a CNC machine with an M function controlling the opening and closing of the jaws.
the Arnold hydrualic vice with pressure preset The Pre-set version allows the clamping pressure to be pre-set to a maximum to avoid deforming or damaging parts.

The pneumatic version of the classic vice opens and clamps with only a partial turn of the handle. 

The solves the problem where the vice is mounted on a machine table with no possibility to make a complete rotation of the clamping handle to clamp and unclamp.
The two piece verson of the classic vice allows the user to insert his own central bar of any length permitting clamping of very long parts.
 
showing the maximum openning of the vices  
High Pressure ARNOLD Hydaulic vices achieve a clamping force of up to 8 tons using the simple turn of the handle without any effort. This advantage makes them ideal for heavy duty clamping in milling machines, drilling machines and threading machines.

- 0.01 mm clamping repeatability.
- Monoblock design to avoid deformation due to high pressure and great rigidity.
- Large opening, up to 375 mm and 845 mm if the body is in two parts.
- Clamping force is 2.5, 4, 5 or 8 tons according to size.
- Fitted with high pressure mechanical intensifier.
- The force applied by the high pressure spindle is transmitted to the work-piece in the exact centre of the clamping jaw.
- Permanent clamping force avoids repositioning the work-piece one day to the next.
- Ideal for long lasting machining.
- Optional power regulator.
- Up to eleven different types of standard jaws.
