Quick Overview

Arnold MAT Mechanical high pressure manual vices for all types of machines

Arnold MAT Mechanical vices, maintain their length irrespective of the size of the part, being especially ideal for use in machining centres.

Possible working positions: supported on the base, on the side or on the head vertically.
Suitable for working in horizontal and vertical machining centres.
Grinding of all surfaces with a parallelism and perpendicularity of 0.02 mm.
0.01 mm clamping repeatability.
Monoblock design avoids deformations due to high pressure and offers great rigidity.
Side windows to enable the interior cleaning of the vices.
Fitted with high pressure mechanical intensfier.
The clamping force is 2.5/4/5 tons depending on the size.
Power regulator optional.
The clamping force permanently avoids having to reposition the part from one day to the next. This characteristic makes it ideal for long term machining.
Angle driver for handle clearance available.

Semi-sphere

The Arnold MAT has a descending clamp system to avoid. that the work-piece up-lift. This is a semi-sphere installed between the moveable jaw and the spindle shoe.

When the clamping force is carried out by the spindle, this pressure is divided in two directions, one of which pulls down on the work-piece.

Clamping possibilities

This high pressure mechanical spindle does not require any maintenance, as long as the optimal liquids are used.

The Arnold MAT mechanical vice has two clamping possibilities, either towards the fixed head or the opposite direction. Normal clamping is towards the fixed head (this is how the vice is supplied). Should clamping towards the interior be needed, just place the spindle on the rear parts of the fixed head, clamped by four screw. Then rotate the spindle shoe and the moveable jaw.

Advantages of High Pressure

Fresmak is dedicated to the manufacture of clamping solutions and high pressure vices. The advantages of high pressure are considerable.

SAFE CLAMPING

High pressure produces intense force therefore the work-piece is very well clamped.
This enables greater feed cut, depth and milling.

INTENSIFIER

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

REPEATABILITY

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.

ZERO WEAR

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.

DURABILITY

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

MANUFACTURE

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.

Mechanical spindle

The intensifier system on these spindles is based on a series of elements which as one supports the others, are able to obtain a power intensifying effect by means of a handle (not reaching 2.5 kg x m).
The basic principles of this system are wedge and roll.
The mechanical spindle is easy to assemble and disassemble and needs practically no maintenance, making it a long-lasting system like no other.

Regulator (presetting power control)

This part offers the possibility of step regulation of the pressure to be used before starting the job, and thus obtaining the repeatability of the clamping force required.

Common characteristics and materials

The main body, the moveable jaw and the spindle shoe are manufactured in cast nodular pearlite GGG 70, providing it with high resistance to breakage and fatigue. In addition, due to the molecular structure it is ideal for absorbing vibrations, which are produced during machining and, as it is more stable in time, enabling ARNOLD vices to keep their shape for more than 20 years.

All Fresmak vices have two longitudinal and transversal key slots (20H7) perfectly machined and perpendicular, which means that they can be rapidly fitted on machining tables without the need for a comparator clock and with the possibility of placing several perfectly aligned clamps.

The vice jaws are constructed in F-5220 - 100MnCrW4 tempered at 60 Hrc, enabling them to withstand high pressure action without deformation and are resistant to the action of swarf, and protected from being dented by swarf.

Similarly, as the guides are tempered by induction of flame hardening and ground to improve the positioning of the work-piece and the sliding of the moveable jaw. This method makes them sufficiently hard so as not to suffer any damage during even the most abrupt machining, nor will they be affected by swarf, acids or cutting fluids.

All Fresmak vices are identified with an individual production number and all measurements are documented at the factory, assuring precision on repeat orders.

Additionally, all the bodies incorporate laterally threaded holes to fit the adjustable stops that the work-piece requires (a standard adjustable stop can be supplied).
