Traub TNL32-7B from Geo Kingsbury includes B-axis

German lathe machine manufacturer, Traub, has taken its 32 mm capacity sliding-/fixed-headstock TNL32 bar auto and added a 100° pivoting B-axis to the upper turret. The TNL32-7B is available in the UK through sole agent, Geo Kingsbury.

The 10-station turret with the B-axis is mounted above the spindle centreline, below which is a 9-station turret. Both move in three orthogonal axes with 20 m/min rapids in each. Rotation of the turrets is NC controlled through 360°, without a mechanical lock, which is faster than indexing a turret and matches the linear speed of a gang toolpost. Chip-to-chip time is under 0.3 second for adjacent turret stations.

The 9-axis CNC machine is intended for the production of complex parts, particularly those needing angular milling and drilling operations.
