Description

Macri Italia designs and produces electric tube bending machines. The company, small but very successful in its field, works almost exclusively to order building 1 to 12 axes tube bending machines in line with the specific needs of the customer.

Advantages:

  • Exclusive software solutions
  • High bending precision and repeatability
  • Simulation of the part bending process with error prediction
  • Modern energy saving system
Design features
Specifications

Easy and user friendly operation

Macri bending machines are CNC controlled and as a result, show excellent accuracy. Continuous monitoring of working parameters of the machine allows reducing tolerances to almost zero.

Capability to produce series of parts with absolute repeatability

Three-dimensional simulation mode calculates processing feasibility and views trajectories of bending and also automatically makes the necessary corrections if the bending sequence is incorrect and may cause a collision between the workpiece and operating parts of machine.

Tube bender control cabinet

All Macri Italia tube benders are operated by an electric information system that can be managed by means of a control cabinet located next to each machine.

System to prevent interference

Unlike other machines, the system not only informs about the interference, but also solves the problem with a complete description of possible obstacles during bending. This allows completely avoiding any damage to the machine and workpiece through the fault of the operator or technician.

Increased efficiency

Increased efficiency (95%) allows to use less powerful engines than are used by identical machines such reducing the vibration and the inertia of the machine bed.

Generation of the missing tool configuration

An exclusive program generates the missing tool (accessory) configuration in bending trajectory calculation process. In case the tool is out of stock, the program automatically produces technical drawings to manufacture it.
