Turn-mill centre with automation options

blank

German lathe manufacturer INDEX has launched a new twin-spindle turn-mill centre with 76 mm bar capacity, 230 mm chuck diameter and a turning length up to 900 mm. The TRAUB TNX220 has a vibration-damping mineral cast bed and generously dimensioned linear guideways in the X and Z axes, a combination that delivers accurate machining and high productivity.

With a powerful Y/B-axis tool spindle rated at 40 kW, 207 Nm, 6,000 rpm above the work spindle centreline, and two 12-station (VDI30) or 15-station (VDI25) live turrets below, the lathe is ideal for one-hit machining of complex parts in cycles that can include 5-axis milling.

Automation options include an INDEX MBL 76 bar feeder, which has been tailored to match the new machine design and is quick to change over to a new size of stock. The loader features excellent damping properties as well as easy setup and is purely electrically powered, so does not require hydraulics. The control system is a modified Mitsubishi TX8i-s V8, which is easy to operate via the iXpanel cockpit solution.
