The SCHIESS-FRORIEP 40 DV is a vertical lathe built in 1980.
The machine was modernized and improved in 1998.
Among other things, a driven tool system (C-axis) was installed.
In addition, the control system was modernized to SIEMENS 840 C.

The large open-sided vertical boring mills with travelling column - type DV -
are particularly suited to situations where likely workpieces frequently change
in diameter but where maximum workpiece dimensions are rare.
Decisions in favour of this type of machine are generally due to minimum floor
space requirement, universal adaptability and economical advantages.
The modern design of these machines is characterized by rigid all-steel
construction optimized by computer - SCHIESS can claim to have done much
valuable pioneering work in this area of heavy-duty machine tool building.
