i All ARNOLD high pressure spindles are governed by the same operating concept.

hydraulic

Here is why we manufacture high pressure clamps.

- Hydraulic spindle

- Mechanical spindle

- PROX Spindle

The ARNOLD vice should always make two types of movement with one single lever. First the approach movement to the work-piece to be clamped and then the high pressure.

To link both movements, all models have the same clutch system.This system, with some small modifications, has been tried and tested for years with excellent results.

Continuing on from the clutch system, all the spindles have a intensifying system which is carried out with a handle.

This intensifier system, together with the position that it occupies within the clamp, is what differentiates the spindles.

To obtain clamping force the handle must be turned.

High pressure produces intense force therefore the work-piece is very well clamped

This enables greater feed cut, depth and milling.

Thanks to this force intensifier, pressure can be obtained with the least effort..

Irrespective of the operator the same clamping force is always obtained.This constant repetitive pressure enables greater clamping precision and positioning of the work-piece.

mechanical

High pressure vice manufacture is very precise. Height, distances between points, finishes, milling, grinding, tempering, hardnesses are all carefully controlled and tested to offer maximum performance on the machines where they will be used.

High pressure clamps do not imply any wear on the vice parts because the movement is axial. On a traditional vice more force is obtained by rotating the spindle and as such the spindle supports the pressure made on the work-piece.This means a lot of wear on the thread (spindle).This is not the case with high pressure, It is the pushrod which makes the force, using an axial movement, and thus does not support much force and the spindle itself, none.

High pressures vice spindles support less wear, and as such have a much longer lifespan.

- Oleo-dynamic spindles

- Pneumo-hydraulic spindles -AUTOMAT spindle

These spindles do not need a clutch; they carry out the approach movement using a handle (oleo-dynamic or automat) or by means of manual cylinder rotation (pneumatic-hydraulic).

The intensifying system is carried out in a similar fashion to the rest of the ARNOLD spindles.
