Sprint 50 options provide a solution tailored to user’s needs

Superseding DMG/Mori Seiki's Sprint and Twin lathes, the Sprint 50 is intended to meet a range of production needs from small batch turning from billet to high volume automatic turning from bar. The Sprint T 50 is suitable for complete, six-sided machining of workpieces up to 51 mm in diameter using speeds of up to 7,000 rpm on both the main and counter spindles. The likelihood is that the twin-turret version will be employed for both chuck and bar work whereas the triple-turret model will be used primarily for bar turning and the production of particularly complex parts. A compact design gives the Sprint 50 a 37% smaller footprint than its predecessor, thanks in part to the lathe's vertical bed with three-point support. The 12-station VDI 25 turrets can accept driven tools at each position and rotate at up to 8,000 rpm. Even in the standard version, the turrets are equipped with the Trifix quick tool change interface, avoiding time-consuming adjustments inside the machine. Repeatability is quoted as being within microns. All turrets are easily accessible by the operator, further speeding set-ups. A Siemens ShopTurn 3?G-control provides tool management and shortens job preparation times due to its multi-channel programming, multi-channel 3D simulation and the flexibility offered by the unlimited combination of ShopTurn cycles and DIN functions. The flexibility is particularly valuable for small and medium size batch work.
