Swiss turning machine offers automation, four tools in the cut

Traub, a brand of the Index Group, has introduced the TNL20 sliding-/fixed-headstock automatic lathe, which can be equipped to use up to four tools simultaneously. An optional robot cell integrated in the machine is available for automated loading of blank shafts or preformed workpieces.

The TNL20 is launched in two versions.

The TNL20-9 has nine linear axes, two turrets (each with eight stations, maximum 12,000 RPM, 2 kW), a four-station back working attachment, and an autonomous counterspindle. It can deploy three tools simultaneously.

The TNL20-11 is equipped with an additional front working attachment (six stations, three of which are live, maximum 12,500 RPM, 2 kW) on an autonomous X/Z slide. By the interpolation of the H indexing axis of the front working attachment with the X axis of the autonomous compound slide, Y machining operations or tool offsets can also be performed with the front working attachment on the main spindle. It can deploy up to four tools simultaneously.

Main and counterspindles (maximum 10,000 RPM, 5.5 kW) are identical and designed as the liquid-cooled module motor spindles.

The work spindle includes a clearance in the draw tube of 29 mm, allowing the use of a standing reduction tube for bar stock diameters up to 20 mm.

To assist unattended machining of blank shafts or preformed blanks, a robot cell is integrated into the front of the machine. Consisting of an articulated arm and a vertical pallet storage device with 28 slots, this automation system allows the operator to feed the lathe with parts that are larger than 20 mm in diameter and can unload and store workpieces produced from bar stock in the pallet storage device.

In addition, the robot cell is prepared for integrating a 3-D measuring device.
