Index-Werke GmbH & Co., KG Hahn & Tessky-fixed headstock automatic-TNK42

CNC fixed headstock turning machine – quick, precise, efficient 2 work spindles, 2 turrets and 1 back working attachment The work area of the TNK is matched to the production of complex machine-turned parts. The TNK ensures productivity and precision in automatic turning up to a bar capacity of 65 mm. The kinematics of the TNK consistently relies on the successful design of the TRAUB CNC sliding/fixed headstock automatic lathes TNL18 and TNL32. With only 5.5 m2 footprint but with 3 subsystems, 2 interpolated Y-axes and 27 tool stations, the TNK offers the economic approach to the production of complex machine-turned parts of today and tomorrow.
