The automatic CNC machines of the heavy duty series manufactured by Schwarze-Robitec GmbH, are optimized precisely to meet the requirements of the chemical industry. They produce three-dimensional tube systems rapidly and exactly. The tube is clamped into the index head and positioned in the space by means of the transport unit and index head. After the first bend, it is directly pushed on and rotated. Thus, three-dimensional tube systems with minimum ovality are produced.
CNC tube bending machines with multi-stack bending tools are best suited for the speedy manufacture of different types of tubes. The multi-stack bending tools process tubes with different nominal diameters on a single system without retrofitting efforts. One of these systems is the CNC 220 HD MW of the HD series from Schwarze-Robitec. It bends tubes with a maximum diameter of 219.1 x 12.7mm and a tube length of up to five meters. With the help of the multi-stack bending tool, up to 70% of the setup time of market-based systems can be saved. It is possible to process tubes of different materials, such as steel, nickel alloys, iron and stainless steel on one tool.
