Unlike universal lathes, here the speed control is infinitely variable through the use of a frequency inverter.

It is possible to provide a “Continuous cutting speed” (V-const), i.e. the cutting speed is maintained during a change in the turning diameter, thus achieving higher precision and smoothness of the surface. By customer’s wish the machines might be implemented, taking into account the linear displacement and positioning through installation of a digital indication.
