ECO-NT – Technique for a perfect 5-axis machining




The new ECO NT series by Reichenbacher Hamuel guarantees absolute con-tour accuracy, the highest surface quality and precision. With the new fixed and low vibration gantry concept, the fixed machining table on a rugged frame and the high Z-axis every classical routing process can be carried out.

All machining positions at the workpiece are machined from all sides. The coordinate table concept with setting bushes and fixing holes allows a safe and quick change of workpieces. With the 3D-measuring pin the reference points are read and memorised in the control. In practise this means highest workpiece accuracies. The ECO-NT types are of special interest for customers who process plastics, composites and aluminium.

Configuration


Efficient and versatile
Demanding free form machining is realised with the 5-axis technique. In every day’s practice the machines convince by optimum shaped working areas, chips falling free upon the chip removal belt and by their robustness. The machine is completely enclosed and the loading area is shut by two sliding doors. With reciprocal loading each door can be opened separately. By removing the middle partition the double working area is available, for example for the machining of long parts.




Examples of Use


The ECO NT has an integrated tool changing system with eight tool places, which is mounted movable to the X-slide. Tools with a length of up to 140mm and a diameter of up to 40mm can be used. Due to less moved masses the machine has a higher speed and accuracy. The high performance frequency spindle with up to 60,000 rpm for efficient machining is equipped with a blast nozzle or a minimum greasing unit which both can be activated and deactivated by the NC-control.
 
Control with safety integrated
This demanding task is reliably solved by the latest generation of controls, the Sinumerik 840D solution line (sl) by Siemens. Operation and programming of the machine are carried out time saving and simple by a graphic user surface. Protection of the machine by safety integrated. Programs can run in automatic mode with the door open under observation of the safety regulations. Reichenbacher Hamuel presents an open system solution which is based on the current industrial standards and can be seamlessly fit into every existing production.
