Multiple bending tool-equipped Schwarze-Robitec 220 HD MW slashes set-up times
The Schwarze-Robitec CNC 220 HD MW is a tube and profile cold bending machine with a total weight of 32 tonnes. It is aimed at the shipbuilding, the chemical industry or for power plant construction where a bending machine must be extremely flexible and able to process tube bends in different nominal diameters and materials in very quick succession.
The CNC 220 HD MW is able to process tubes with maximum diameter of 219.1 by 12.7 mm – in a tube length of up to 6 m. Despite its size, the plant is extremely flexible in operation. With its multiple bending tool, it is estimated by Schwarze-Robitec that up to 70% of the set-up times of conventional plants on the market can be saved. It is therefore possible to process tubes in different materials such as steel, copper-nickel-iron alloys and stainless steel on one tool and with no conversion work. At the same time, thin-walled and thick-walled tubes with different diameters can be bent.
The integrated Spring Matic measuring system determines the rebound of the tube after initial bending. It is then immediately 're-bent' resulting in bend accuracy of 0.5º.
