CNC Tube Bender

3-axis CNC tube bender for the linear bending of tubes up to 65 mm diameter.

The tube bending machines of the ACH series are fully automatic bending machines with CNC 3 axes: bending (Y axis), advancement (X axis) and rotation (Z axis).

This hybrid tube bender has been developed for the accurate bending of tubes and profiles. The main axes are electrically controlled, while the auxiliary axes are hydraulically controlled.

  • ACH Memoli

The extremely small bending head is made of steel with a chain-driven transmission to ensure more space in the sub-bending head; in this way, the machine can bend in a single cycle even tubes with the most complex geometries.

The setup times are extremely short and ensure great flexibility.
The ACH series of CNC mandrel tube bending machines is developed and produced entirely in Italy, in close collaboration with the main tube bending Companies.

All of ACH mandrel bending machines are equipped with MEMOLI interface – a 3D bending software, designed for tube bending applications. Extremely easy and intuitive, it allows you to program directly through the adjustment of LRA (length – rotation – angle). MEMOLI software is also compatible with a wide variety of CAD software programmes (Autocad, Inventor, Solid Works, Pro Engineer, Rinhoceros etc.).

Among other strength points, it offers automatic springback compensation, it memorizes tool configuration and geometry, and it has anti-collision properties for component feasibility, without prototyping or material waste.

Frequently Asked Questions about ACH

ACH cnc tube bending machines are automatic machines in which the bending operations are handled entirely by the machine; the operator will only have the task of loading and unloading the tube. In semi-automatic ETM-H tube bending machines, on the other hand, the operator will have to feed the tube between bends.

ACH tube bending machines are 3-axis controlled machines.

Yes, all of our ACH cnc tube bending machines are equipped with an anti-collision simulation system.
