DVS UGrind – Incredibly impressive. – Efficient complete machining with
grinding, turning and measuring tools on a single multifunctional head – Ideal
for small to medium batch sizes of shafts and chuck components with a
centre-to-centre distance of up to 1,200 mm – Machine bed made of natural
granite for high dynamic and thermal rigidity – Consistently precise machining
results thanks to a hydrostatically supported tailstock – Faster achievement of
targetdimensions thanks to the intuitive DVS UCee operating system – Footprint
of just 7 or 8.5 m²,including coolant system.

Highlights:
> Complete machining in a single set-up. Turn whatever can be turned; grind
whatever needs grinding.
> Short set-up times, quick to programme – a machine that’s a pleasure to
work with and gets the job done quickly.
> Intuitive and ergonomic: good accessibility, crane loading,
intuitive operation via touchscreen and ready-made programme modules.
> Compact footprint thanks to integrated coolant treatment
> Optional automation solutions: with our ULoad or a customised solution, for
example from rbc robotics, the DVS UGrind can also operate fully automatically.
