All models of Comac double pinch style profile bending machine can be equipped with electronic automatic control systems to improve accuracy and consistency of jobs and enhance the rate of automation.
These controls are simple 2-axis programmable positioning devices, or CNC controls.
Programmable positioning devices are useful to join straight parts to bent parts and to perform multiple-passes jobs in a more consistent sequence of operations.
CNC controls are required to accomplish multi-radius curves to be produced in medium-large batches with high consistency and excellent quality of transitions between the different radii, even with difficult materials such as thin-wall tubes.
This can be achieved by controlling simultaneously three axes, i.e. the profile feeding and the positions of the bending rolls.
Among the hundreds of parts produced with CNC-controlled rolls, some samples are: greenhouses, handrails of cruise boats, conveyor rails, variable-pitch pipe coils for boilers, pancake coils, commercial signs, etc.
Two versions of CNC control are available; both are based on industry standard non-proprietary hardware (PLC’s and Industrial PC’s worldwide available), in order to insure immediate availability of spare parts and local technical support.
