The Traub TNM28
High Performance Machining
Traub TNM28 CNC Multi-slide automatic with integral bar feed and magazine
The Traub TNM series has a CNC multi slide automatic classification for complete machining of the smaller work piece up to 28mm diameter. With 4 NC – axes, it is designed to machine small and medium batch sizes alike, it easily replaces existing cam-operated lathes without any loss in output. On the machine are four exceptionally sturdy plunge slides, arranged around the main spindle to accommodate form tools up to 40mm wide, each slide can be individually programmed. The NC controlled star-type turret can accommodate 8 tools, located in one of the turret stations is a hydraulically operated pick up spindle for supporting the part for ‘pip-less’ part off. Simultaneous machining on the part off face of the component can be carried out at the Rear NC BAST controlled station equipped with two driven tools.
For complete automation the machine is interfaced with the Traub integral bar feeding magazine. Parts removal is via an integral chute that transports the finished work piece out of the machining area.
