customer’s requirements in terms of ovality and wall thinning. The custom machine also features bi-directional communication with the Eagle TMS-100 tube measuring machine, to enable accurate parts to be produced with the least amount of scrap – essential for the small part runs required for the project. In addition to the custom EPT-100 XPH hydraulic bender, Eagle also supplied an EPT-25 EPS (25mm capacity) multi-stack all electric CNC tube bender for use on smaller pipe diameters. This machine was also coupled with the Eagle TMS-100. The multi-stack design of the bender minimises tool changeover to optimise production efficiency. All machines were delivered in a time period of 12 weeks.

High-speed bevelling, facing and counterboring

Protem GmbH, Germany, produces the US-HSB series, designed to bevel, face and counterbore tube and pipe at extremely high speed. Fully hydraulic, starting with the inside clamping system, the tool holder rotation and the feeding of the tools, the machines can be used either in the workshop as prefabrication PFM, or on-site as bevelling tools for high quality orbital welding. The machines will perform any high quality welding geometry preparations, from standard steel pipes to stainless steel, duplex, super duplex and others commonly used in the modern field of welding. The machines feature a lifting bracket to enable easier transportation and positioning inside the tubes to be bevelled, and an inner self-centring hydraulic clamping device requiring only one operator to handle the machine. Two inside profile tracking tool holders rotate simultaneously on the tool holder plate to perform the bevelling, facing and/or counterboring. If necessary, all preparations can be done at the same time and at a very high speed, on any oval pipe, leaving a root face at a constant width, optimally for the high standard bevel geometry in modern orbital welding.

World’s ‘fastest’ arc welding robots

simplifies programming. The SSA2000 is suitable for multiple-unit installations where two or more robots interact closely, and for applications involving areas that are difficult to reach or where there is a risk of interference from fixtures. The SSF2000 robot, with a 6kg payload, is similar to Motoman’s HP6 model and is designed for arc welding with traditional external cabling and handling. It can be used with vision sensors and with torches that have an integrated wire feed. Both of the new welding robots, which have a reach of nearly 1.4m and a repeatability of ±0.08mm, are controlled by Motoman’s NX100 controller, featuring robust PC architecture, Windows CE programming pendant, and easy-to-use Inform III programming language.

Two new six-axis industrial robots for arc welding, claimed to be the fastest on the market, have been introduced by Motoman Robotics, UK. The latest all-electric models, Super Speed SSA2000 and SSF2000, are 40 per cent faster than previous robots owing to advanced motion control of the axis movements. The resulting 15 per cent reduction in weld cycle times significantly raises productivity, and weld cycles are speeded further by minimising arc on/off time. The SSA2000, with a 3kg payload, has the same upper arm as the Motoman EA1400N Expert Arc robot. Welding cables are integrated and the torch is mounted in- line with the welding axis, which eliminates cable interference, reduces cable wear and fi Motoman’s two new Super Speed arc welding robots, SSA2000 (left) and SSF2000

› Arla machining unit with motor spindle

All units are directly driven by servomotors, providing high stiffness in radial and axial direction. The machining units are designed for high torques in order to realise a solid automated manufacturing process with a very low cycle time. The revised DUM models with integrated motor spindle provide very high torques and are also available with internal tool cooling, and an optional manual or automatic tool clamp. The concentricity of the spindle units is less than 0.002mm, and according to the model size, the supported tools must meet the HSK standard (HSK 50-125). The company can also supply solutions for two or three axes. Typical applications are in the automotive and aircraft industries.
