Cutting

Fibre laser cutting THE LD1500PS f model from Balliu is equipped with a fibre laser instead of the traditional CO 2 laser.

reflective materials. Especially in thin materials, the fibre laser can reach higher cutting speeds than a CO 2 laser. The high power linear motors accommodate these high speeds. The new machine has been designed with a look that clearly distinguishes the fibre version from the CO 2 version. The machine is currently available with a 1kW, 2kW, 3kW or 4kW laser. Standard sheet sizes are 1,250 x

1,250mm; 1,250 x 2,500mm; 1,500 x 3,000mm; 2,000 x 4,000mm; and 2,000 x 6,000mm. Customised sizes are possible on demand.

The claimed advantages include 30 per cent less power consumption, less maintenance because of the simplified optical path, and fewer consumables because of the solid state laser. The different laser beam wavelength allows for new applications such as cutting copper and other highly

Technology for straightening and cutting VIOLI Srl specialises in the design and production of industrial machinery dedicated to the manufacturing of tubes, wires and bars, typically used in the processes of drawing, winding, straightening and cutting. The company’s MRFT series is intended to straighten and cut tubes and profiles – wrapped on coils – with a diameter up to 10mm. It consists of an unwinding reel, and a drawing unit with both shaped rollers and rollers with plastic polymers. Tubes are cut according to requirements with a tolerance of ±0.1mm.

depending on the products that need to be processed. Violi also offers a range of straightening machines able to process cold drawn tubes and profiles made of steel or other metals. The line of straightening machines includes the MRT series with hyperbolic rollers for the straightening of bars with diameter from 3 to 63mm. The MRP series is suitable for straightening complex-shaped tubular profiles made of ferrous or non-ferrous metal.

The MRFTS1 model with saw blade is suitable for cutting tubular profiles and thermocouples. The MRFT series is completed by a tray that collects the cut bars and discharges them into a collector. Optimisations vary according to customer specifications and

End cut-off system BRANDT Engineered Products has introduced a new end cut-off system to increase seal life in downstream hydro-testers, and to quickly cut pipe samples.

removed prior to any further processing. Brandt specialises in machine and system design, manufacturing, installation and commissioning for the tube, pipe and mining industries, and has been providing finishing floor solutions for over 20 years.

Preparing the end of the pipe with a bevel prior to hydro-testing prolongs seal life in the hydro-tester by removing any unwanted burrs on the outside of the pipe, to avoid cutting seals as the pipe enters the test heads. The end cut- off system can be set up to bevel the ends of the pipe or to part off a sample and then bevel the end of the pipe. This allows the operator to prepare various lengths of samples for use in flat tests, ring hardness tests or tensile strength tests, improving process control and meeting manufacturing requirements. Damaged or hooked pipe ends are also

The end cut-off is designed to ensure quick, accurate parting and bevelling on pipes prior to hydro-testing. It also provides quick cut-offs in lengths of up to 457.2mm (18") in order to prepare various test samples. The pipe is elevated and loaded into the end cut off spindle, which parts and then bevels the pipe at various feed rates and surface speeds.
