Schwarze-Robitec bending technology increases Buigstaal capacity

Large family of mandrel tube bending machines transfluid, Germany, has launched the DB650ST-SPS mandrel tube bender, part of a family of ten mandrel tube bending machines. These machines all feature the same three axis ‘SPS’ user friendly numerical control. Bending capabilities start from tube sizes as small as 6mm and range up to 220mm OD. Consistent accuracy is possible with the automatic bending and digitally controlled positioning of rotation and length. All models are designed with a special recessed tool shaft to accomodate small bend radii. The transfluid DB650ST-SPS is a semi- automatic mandrel tube bending machine complete with an upgrade for CNC-style operation. It offers forward, back and rotational motorised positioning to remove the need for mechanical stops. All 3-axis data is input using a touch screen control, with instant retrieval of stored programme data by part or job number. With a hydraulic pressure die, hydraulic

To cope with the growing market demand, Dutch-company Buigstaal Tube Bending Alkmaar has significantly increased its capacity with the purchase of a new Schwarze-Robitec CNC 80 TB MR tube-bending machine. With this new CNC 80, Buigstaal aims to increase its capacity by 50 per cent in this tube size range. The Schwarze-Robitec bending machine operates by the transport bending fi The Schwarze-Robitec CNC 80 TB MR tube- bending machine

principle, which increases the bending performance and improves the accuracy of the product dimensions. The machine bends tubes up to 88.9mm diameter and has the capability of multi radius bending. With delivery in May 2007, the machine is due to be fully operational by July 2007. Part of the Van der Wel Group, Buigstaal offers just bent tubes up to complex assembled tube products for the automotive, defence, energy and industrial markets. At the end of 2006, the company received an ISO 9001:2000 certificate from Bureau Veritas.
