Turning centre has VMC power for milling
A mill-turn centre combines the power of a vertical machining centre with the capabilities of a lathe and offers thermal stability, very low levels of vibration and high damping.
The Mori Seiki NT4250 DCG mill-turn, multi-tasking centre combines the power of a vertical machining centre with the capabilities of a lathe Its construction uses massive castings, driven at the centre of gravity technology, direct drive motors, octagonal ram and box-in-box framework to provide thermal stability, very low levels of vibration and high damping characteristics

System proves more versatile than pallet shuttles
With experience of radial and shuttle layouts, Plenty was seeking a more compact and versatile system. A Fastems DMC-MD medium duty pallet handling installation provided the answer.
Visitors to the UK's MACH 2008 machine tool exhibition will be able to see the machine in action.
Additionally, there will be a second machine 'undressed', so that the full extent of the engineering, which goes to make up the machine's 'Pure Technology', can be appreciated, said Mori Seiki.
The power of the machine enables metal removal rates of 550cm3/min to be achieved, as well as acceleration levels of 0.8G and rapid movements of 50m/min.

Long-bed machining centre is built for speed
A substantial three-way guideway system, which supports the longitudinal travel of a moving column, provides theSVL5020 long-bed VMC with plenty rigidity for the high speed milling.
Direct drive motors in the spindles, B-axis and milling head eliminate the vibration associated with belts and gears, and include integral cooling jackets for thermal stability.
* Multi-tasking - the versatility and flexibility of the NT Series enables the machine to complete a wide range of machining tasks including the following.
* Internal and external tuning.
* Drilling.
* OD milling.
* Hole machining.
* Angular machining.
* Gear and spine hobbing.
* Simultaneous turning and simultaneous milling.
The power of the milling capability within the machine is equivalent to the Mori Seiki NH Series of machining centres.
This greatly increases the range of parts which can be manufactured when compared with other mill-turn centres, said Mori Siki to manufacturingtalk,com.
This allows companies to combine operations which would have needed several conventional machines to complete, enabling them to achieve one hit machining.
* Automatic tool changer - as well as fast acceleration and rapid movements, the NT's automatic tool changing (ATC) is also quicker.
Located outside the machining envelope, the ATC is separate from the machining area, which ensures a clean environment and enables the machine to achieve a chip to chip time of 3.4s, compared with 14s on the MT.
Programming and verification are easier on the NT, thanks to its MAPPS III control.
Canned cycles simplify and speed up the creation of new programs, while real time collision checking algorithms ensure safety and reliability.
