With the newly developed CNC 40 Rotary, Schwarze-Robitec GmbH offers a CNC-controlled, tube cold bending machine for bending tube systems to the left and to the right. This is facilitated by an additional CNC axis from the loosely mounted bend former in the innovative bending head. As a result, the CNC 40 Rotary considerably increases the flexibility of bending processes – even in the case of tubes with shapes already preformed on the straight tube. It processes tubes with diameters from 8mm to 40mm. Schwarze-Robitec has developed the current solution in order to allow time and cost effective processing by users in the future. “Put simply, the use of the loosely mounted bend former allows the bending head to move independently of the tool,” explains Schwarze-Robitec GmbH Manager Bert Zorn. The advantage of this is that even tubes with the smallest bending radii and complex curve shapes after bending can be easily moved out of the range of collisions and interfering contours. As this new solution needs no second bending head, the company has been able to decrease the investment in the CNC 40 Rotary by around 20% when compared to conventional solutions. In addition to these significant reductions of acquisition costs, the tube bending machine, which works with up to 13 CNC-axes features intuitive operator guidance on the control system. “A single day of initial practice is enough to understand the control concept and operate the machine intuitively,” said Bert Zorn.
