High-speed shearing technology

Cutting and bevelling of tube sections PROTEM’S CTA model is designed for production or prefab workshops, and allows cutting and bevelling of tube sections. The cutting is square and the bevel angles are precise and the cold machining process gives a clean surface finish. The tube to be cut is kept stationary by the machine’s outside clamps, while the tool bits mounted on a rotating plate are put into rotation around the tube to perform the cut. While cutting, the machine performs bevelling on both ends. However, this radial cutting principle does not allow the performing of any

IN recent years increased world demand for higher tensile materials including austenitic and ferritic grades of stainless steel has created the need for a more reliable cutting solution, as precision cutting of stainless steel tube has always been fraught with difficulties. To satisfy this challenge, Thermatool engineers have introduced a series of strategic design enhancements to its range of Alpha Flying Shears. One such example has been the introduction of aircraft-grade aluminium for use on the latest die-sets, where increased strength-to-weight ratio – several times greater than that of steel – has significantly improved operating performance, reliability and overall cutting efficiency. The latest Alpha Flying Shears also benefit from fully automated lubrication of the entire cutting system. Automatic lubrication of the die-set has also served to reduce wear and improve blade life by helping to

maintain correct blade alignment longer, thus reducing mill downtime. The latest generation of modular die-sets have been re-designed to reduce vibration, thereby improving blade life while shearing higher tensile materials including austenitic and ferritic grade stainless steels. Central to the Alpha die-set design is the patented, horizontal, double-cut scarfing mechanism, which is rack and pinion driven and designed to deliver a smoother transition through the entire cutting cycle, a significant improvement on former cam- driven systems. The latest generation of Alpha shears also utilise AC servo accelerator systems, proven to deliver millions of cut cycles with cut length accuracy up to ±1mm.

fast cleaning of pipe ends! With theTPP 5090 tube and pipe ends as well as plates can be polished very quickly. Both inside and outside at the same time. Check the demo video on our website --> www.wortelboer.ws. ...TPP 5090 polish machine

NEW!

Both spindles of the air driven TPP are adjusteble to the thick- ness of the pipe wall or plate thickness. Also speeds are ad- justable. Call or email us for more information.
