TORNOS MICRO-8 CNC turning centre

TORNOS MICRO-8 CNC turning centre built in 2008 in Switzerland is distinguished by its extensive machining capabilities, sturdy design made of the highest quality cast iron and compact size. The machine designed for ultra-precise machining of workpieces with a maximum diameter of 10 mm is equipped with two reliable spindles to maximise production efficiency in any production facility, even during the most demanding challenges.

The main spindle and counter spindle with integrated thermal control, retractable collet and ceramic ball bearing run on guides with increased rigidity. Both spindles are powered by reliable FANUC motors, ensuring that the necessary power is supplied for the versatile use of all the cutting tools located in the 20-position linear magazine. The arrangement of the tools in the magazine has been made in such a way as to allow simultaneous machining on the main spindle and the counter spindle. In this way, the TORNOS Swiss-type automatic lathe allows, among others, simultaneous face turning and drilling or simultaneous roughing and finishing.

The offered TORNOS MICRO-8 automatic lathe also features extensive equipment, consisting of, among others, the DONALDSON TORIT DCE multi-chamber oil mist extraction system, the ROBOBAR SBF-210 bar feeder and the easy-to-use FANUC Series 32i-MODEL A CNC control. The MICRO-8 CNC dual-spindle lathe weighs approximately 2000 kg.
