Special Fabtech – Axxair

The orbital cutting machines from AXXAIR are equipped with a concentric clamping device

Conversely to clamping equipment using a vice, the concentric clamping is delicate and strong at the same time. This device is equipped with 3 to 16 jaws according to the diameters of the tubes that have to be cut and then welded with orbital equipment. Generally, the stainless steel tube have a thickness of maximum 3 mm. This means that in industrial sectors such as vineyards, dairy and pharmaceutical sector, as well as in the food industry, these tubes are largely represented according to the current European standards.

These tubes are particularly thin. If you use a vice, it will distort the tube. This tube cannot be repaired and becomes scrap. The orbital cutting machines from AXXAIR are distinguished by the innovative concept of concentric clamping, even permitting to repair an oval shape of a tube. .

If you use a clamping system with 4 jaws, they will be placed:

at 0°- at 90°- at 180°- and at 270.

In this way, the tube does not suffer and it will not be weakened.

Stainless steel clamping

The concentric clamping systems from AXXAIR are equipped with basic jaws. They are fixed to columns which move close to the tube and then clamp them.

Why did we choose stainless steel for the jaws? The answer is quite simple. Any other material than stainless steel would pollute the tube after a certain time of functioning. In order to guarantee a perfect protection towards these external attacks – for instance corrosion, the protection of food or any liquid routed inside the tube – only stainless steel is largely recommended, not to say mandatory.

The basic jaws equip AXXAIR orbital cutting machines. When using AXXAIR equipment, you will have no damage or loss in productivity.
