Twin-opposed-spindle mill-turn lathe
introduced
A twin-opposed-spindle CNC mill-turn lathe can be equipped with two, three or four disc-type, Y-axis turrets, each capable of holding 10 driven or static tools on both faces.

Stiffer CNC turning centres up metal removal rates
Considering resonant frequency, Index-Werke has redesigned of CNC turning centres to reduce vibration and double the machine structure stiffness to maximise metal removal rates.
Up to 80 tools can be accommodated on what is regarded by Traub, Germany, as a conventional design of lathe.
UK agent, Geo Kingsbury Machine Tools said that usually, for a CNC lathe to deploy such a large number of tools, it iwould normally have a single-station turret head with automatic tool change (ATC) serving tools from an external magazine.
Traub reckons a conventional turret to be more robust than an ATC-served one, so higher accuracy machining may be achieved on the TNX65/42.
Providing more rigidity, the 10-tonne TNX65/42 is built on a heavily ribbed, cast iron slant bed that dampens vibrations and promotes close tolerance machining.
Tool change is faster with a disc turret than when cutters are exchanged from a magazine, said Kingsbury, leading to higher productivity.
Kingsbury said that the balanced turning of slender workpieces or two dissimilar machining operations performed simultaneously are established advantages of twin-turret turning - performed at both spindles.
The TNX65/42 has the possibility of having tools in three turrets cutting simultaneously at either spindle.
Kingsbury said that cycle times can be as quick as a multi-spindle automatic lathe.
Of symmetrical design, the TNX65/42 has its turrets arranged on independent slides above and below the spindle centreline, giving maximum versatility for optimising cycle times.
The headstock is thermo-symmetrical and the synchronous, C-axis motor-spindles are of identical rating at 24kW/5,000 rev/min for the 65mm bar capacity machine and 28kW/7,000 rev/min for the 42mm bar model.
Hybrid bearings are fitted as standard for increased service life.
Control is the TX8i-s running Traub's own software.
The CNC is optimised to the manufacturer's lathes and is backwardly compatible, allowing programs to be run that were created on earlier controls.
Realistic 3D simulation shortens set-up time and avoids collisions when producing first-off components.
On-line and off-line programming with powerful synchronisation and optimisation of up to four machining sequences can be provided by Traub's optional WIN FLEX IPS graphical object-orientated software.
