DVT250 is a latest design 2-spindle (1 x top / 1 x bottom) vertical lathe
Instead of two machines linked by automation and turning station you need
just one DVT to machine workpieces from two sides with the highest
precision. Automatic loading of the machine through the suspended spindle
and machining in a closed workspace provide the basis. The direct
operation into the clamping device of the fixed spindle after machining
takes place without loss of quality between the two clampings
Parallel to the machining of the second side the loading of the suspended
spindle takes place again and the machining continues. Unloading of the
fixed spindle is managed through a separate gripper. The finished part is
removed by an integrated automation so that raw and finished parts are
clearly separated for the operator
