Quick Overview

Arnold high pressure manual vices for milling machine and drilling machine

High pressure Arnold Mechanical vices achieve a clamping force 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 avoids 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 2.5/4/5/8 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 seven different types of standard jaws.

VERSIONS

1. Standard vice.

Standard shape highly valued for decades. Clamping to the machine table is carried out through the lengthwise orifices and slots of the vice.
Can be supplied with a rotary base.

2. Straight vice.

The narrow figure enables one to be placed alongside the other, making up a large clamping unit for large work-pieces.

3. Two part straight vice.

Able to clamp any work-piece however large it is.
Clamps the work-pieces on top of the guides on or top of the table.
An inner tie-rod joins the two parts of the vice.

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).
