EQUIPMENT
Grid solutions
To ensure maximum flexibility in machining operations with frequent changes of workpieces, our grid solutions are optimal: you can quickly create a new clamping structure and change it in no time whenever necessary.
Dedicated plates
For machining operations which recur periodically, the ideal solution is the system with dedicated inset plates, which can be fixed with screws or zero-point systems: we can create one B for you, with an a purposely-built tool magazine, to be instantly ready as soon as the need arises.

MATERIALS
Our clamping solutions are available in different materials to best suit your requirements.
Granisint
The mineral agglomerate known as synthetic granite or Granisint combines the typical lightness of aluminium alloys with the vibration dampening capacity of cast iron, improving on both. Read on…
Even lighter than aluminium, it provides an almost nine-fold reduction in vibration compared to cast iron; it is also characterised by high stability and low thermal conductivity, with less thermal expansion and distortion.
The lightness of the material, free from surface oxidation processes, creates less load on the structures, making it possible to support heavier parts without exceeding the maximum permissible load.
Displacement inertia is reduced; high vibration damping enables highly dynamic machining.
Cubes, towers and four-sided crankwebs are available in Granisint. Close
Grey Cast Iron
Our lamellar or grey cast iron is produced using recycled cast iron and steel, in full compliance with the principles of circular economy, with the addition of graphitising elements.

The resulting material undergoes treatments which ensure excellent resistance to wear and chipping.
Its vibration dampening capacity is particularly appreciated, thanks to the presence of graphite flakes: a fundamental characteristic to improve the quality of machining, even at high speeds, increasing tool life.
The grey cast iron used to produce our components is standardised and can be surface hardened.
All our clamping solutions are available in grey cast iron. Close
Aluminium
The light metal par excellence, champion of the circular economy due to its perfect recyclability at the end of its life cycle, aluminium carries numerous advantages in terms of efficiency in handling and use: above all thanks to its specific weight, just over one third of that of most cast irons. Read on…
Corrosion resistant, thanks to its lightness it places less strain on machine structures such as guides and pallets.
All of this without compromising strength, which is ensured by the presence of special alloying agents and treatments to improve its functional properties.
For our aluminium clamping and fastening solutions, we use artificially aged casting alloy, or rolled and stabilised alloy.
Cubes, plates, towers, crankwebs, overpallets and overlays are also available in aluminium. Close
Steel
Particularly tough and resistant to corrosion and oxidation, steel is appreciated where high temperatures, processes requiring washing with aggressive detergents or environmental conditions make it necessary to resort to the proverbial strength of this material.

Read on…
For our clamping and fastening solutions we use various types of steel: standard construction steel, carbon steel and special heat-treated, case-hardened and tempered steels.
The best part of our steel clamping systems for mechanical machining are available with surface hardening and burnishing treatments. Close
