Simultaneous cutting of four tubes

Bewo Cutting Systems BV, the Netherlands, has introduced the SCF-90 Quatro cutting system that offers innovative technology and improved performance. With 75 years of experience, the company was recently acquired by Nivora Holding BV. The SCF-90 Quatro features complete and automated fast changeover, with extremely high output figures and a new state-of-the- art centralised control system. The newly designed full CNC length control feeding system enables the user to cut up to 4 or even 5 tubes at a time, with capability to handle round, square or rectangular tubes. The SCF 90 Quatro has been fully designed and developed in-house by Bewo’s highly skilled and experienced engineering department. The working space has been screened entirely, resulting in minimum sound levels.

The transparent protective hoods can easily be opened if the total line has been entirely shut down. This machine adheres to all CE security certification rules.

The Bewo ‘Prisma’ jaw system allows four point clamping on round, square and rectangular tubes, together with simultaneous clamping of multiple tubes. A load cell and camera system takes care of a continuous and reliable production process. Additional links such as brush deburring, measuring, tube washing and different tube packaging systems can be fully integrated into the machine control. A complete SCF-90 Quatro cutting line, including deburring, measuring, washing and stacking can handle an output up to 6,000 pieces per hour.

The new Bewo SCF-90 Quatro cutting line offers optimal flexibility, to enable the suppliers of added valued fixed lengths to

stay competitive in the market. Bewo BV – The Netherlands

Tube straightening and cutting machines Ravni Technologies, France, is the manufacturer of a complete range of tube straightening and cutting machines for coils with a diameter range of 1 to 24mm. The tube processed using this machinery is steel, stainless steel, copper, and coated tube. The standard line includes a single or double motorized decoiler that is synchronized with the machine. A feeding station with caterpillars enables a feeding speed of up to

180m/min and a chipless cut-off unit. An independent encoder measures the length – the tolerance level is ±0.3mm over one metre. The components of the line are designed for easy use. All machine functions can be found on the user-friendly control panel, which monitors and displays the different stages of the production process in detail.

 Mitchell variable wall tube drawing line, including 250,000lb three die tube push pointer, 225,000lb variable wall tube drawing machine and special tube handling system The line was designed primarily to produce variable wall core drill blank tubes in multiple lengths. Core drills are used in mineral exploration. The line is scheduled to be in full production in 2009. With so much emphasis on weight savings and enhanced material properties, variable wall tubes allow more core drills to be transported to the work site per transport load than the previous style of core drills. Furthermore, the weight savings linked to variable wall tubes also allow deeper drilling depths. In addition, the cold working of the material via the drawing process enhances the body strength of the core drills.

As with all the company’s machine models, the MDC10-Tucm is designed for fast tool changeover. The straightening rollers, settled on a rotating table, are adjustable and equipped with digital indicators to recover the appropriate regulations for every diameter. A digitized tube chipless cut-off unit can set the speed and depth of penetration of the wheel into the tube according to the thickness. The advantages of this new technology are traceability and control of the process. Ravni Technologies can provide worldwide installation, training and set-up of the machine.
