Smaller turn-mill centre for one-hit production of complex parts

The NTX series of B-axis turning and milling centres built by DMG MORI has been expanded by a new model at the smaller capacity end of the range, which now comprises five machines. The compact NTX 500 is able to turn components up to 558 mm long and 120 mm in diameter, or up to 40 mm diameter from bar, using its two Y-axis tool carriers and twin opposed 8,000 rpm turnMASTER spindles.

The size of the machine coupled with its power and rigidity make it especially well suited to the production of implants and other medical parts from challenging materials.

The in-house manufactured compactMASTER B-axis tool spindle is rated at 30,000 rpm as standard, optionally 42,000 rpm. Being only 250 mm long, yet with a swivel range of ± 120-degrees and 150 mm of Y-axis movement, it allows generous axis travels and versatile metalcutting opportunities. The tool magazine can be loaded during machining and has pockets for 38 (optionally 76 or 114) Capto C4 / HSK-T40 / KM40 cutters.

The NTX 500’s second tool carrier is a BMT 42/64 turret below the spindle centreline with 16 tool positions and a Y-axis travel of 60 mm. It enables simultaneous machining together with the B-axis spindle for short cycle times when processing complex parts.

Automation solutions are available for the turning centre, including integrated bar feeding from the right hand side and an in-machine travelling robot (IMTR) that allows automatic workpiece unloading from the main and counter spindles.
