Comprehensive range of forming and bending machines

latest generation components to ensure a very broad range of advantages. Features include low power consumption, high productivity, precision and repeatability of the axes, left and right bending, and pushed carriage for rolling. The machine is capable of multi-height and multi-radius on several levels and two tools. Other features include ergonomic height of loading, electronic crank for programming by training, programming in force or position, and memorized adjustments tools. Silfax – France Latest Crippa bending machine with electric operation Crippa, Italy, is the manufacturer of the CA1132 bending machine, which is based on the existing model CA532. With the same basic structure as the CA532, which bends metal tubes with a diameter up to 32mm, the CA1132 offers a number of advanced features. The CA1132 is a CNC machine with 11 axes controlled by motors with digital adjustment. Unlike the CA532, the CA1132 involves electric and not hydraulic adjustments. In addition to the existing axes adjustments – such as tube progress, rotation on its own axis, positioning, and bending head unit movement – other movements are now electrically adjusted. The operator mainly works on the CNC by setting and checking the adjustments without touching the bending machine. It is now possible to use CNC ‘software keys’ that automatically avoid any wrong movement that can cause possible damage, interference or collisions. There is a significant reduction of waste during the presetting and testing phase. In addition, there is the possibility to perform micrometric adjustments – fine adjustments that were not possible with other models. This feature permits the bending of smaller tubes, such as AGR tube, where adjustment accuracy is needed. Crippa SpA – Italy Fax : +33 4 72 31 06 19 Email : info@silfax.com Website : www.silfax.com

Silfax Group, France, is the manufacturer of fully electric bending and endforming machines. The company has recently launched the SHD4N, a hydroforming machine for corrugated thin wall tube (application: EGR tubes/pipe fuel tank). The SHD4N has 4 electrical numerical axes, a Siemens 840D numerical control and

611D drivers (full digital technology). With a high production rate (up to 95 per cent), the machine is capable of hydroforming different convolutes in one shot. Machine features include an integrated loading and unloading system, memorized tools adjustment, reduced changeover time, auto diagnosis, low maintenance, and modem connection (as option).

The company has also developed the fully electric SE 50 LR CNC bending machine. With 10 axes, this machine is designed for a tube diameter of 50mm and production of units from one to one thousand. The design of the SE 50 LR is associated with the

CNC tube bending machines with 13 axes Fullstage Technologies, Germany, offers a broad range of reliable bending and cutting equipment for the tube and wire industries. The company has manufacturing partners in Japan, Taiwan and the US, enabling Fullstage to offer a wide range of machinery.

The company’s range includes CNC tube bending machines from Chiyoda, a Japanese market leader. Equipped with as many as 13 axes, these systems can bend tubes with diameters up to 250mm.

Chiyoda and Fullstage also offer a line of benders for very tight radius (1D or smaller) applications up to 200mm in diameter. Automatic loading and unloading capabilities are available for each machine. Fullstage also offers cutting systems from Chiyoda designed specifically for coiled tubing, as well as Japanese and US cutting machines that cut tubes up to 65mm OD and provide solutions for extremely small wall thicknesses (from 0.2mm).

Services include installation, regular maintenance and complete repairs. Fullstage is a worldwide supplier with a current emphasis in Europe including Russia. The company can provide an equipment solution that meets each customer’s individual requirements (eg quality, productivity, manufacturer, price).
