| The development of duplicate work holding technique in combination with an automatic 5-head CNC sawing unit has made it possible to manufacture a precision saw which is capable of eliminating bottlenecks during sawing processes on adjusting lines for long-term products. It is now possible to cut 2 bars into 8 work-pieces in one cycle at the same time. This new generation of high-power sawing machines was launched at wire D�sseldorf 2004 by the German company Dornieden Anlagentechnik GmbH.
A cutting output of up to 38 tonnes per hour (depending on the diameter, rod length and a quality of up to 1,200N/mm2) sets new standards. Furthermore, sawing accuracy remains inside limits, not exceeding �0.5mm. The sawing machine can process sawing stock ranging between 14 and 70mm � and lengths of up to 13,500mm. The high profitability of the machine does not only originate from high-sawing output and precision. Further outstanding characteristics are reduced adjusting times required for the line, which is achieved by software menu-guidance oriented on the various cycles. The operator only needs to enter production-related parameters, such as work-piece length, material quality, and diameter. This can be done by the machine operator or by centralised ERP specifications, since the automatic 5-head sawing machine has open interfaces to the control-related and mechanical periphery environment. This equipment can be integrated into existing production lines without difficulty. The technology featured by the new 5-head CNC sawing unit is also available on the company�s automatic sawing units with 3 or 4 sawing heads.
