As a results, our own machines have now the following features:
- nr 5 controlled axis + nr. 1 rotation controlled axis - for rings Ø 25÷72 mm
- Outside diameter finishing is realized by nr. 2 interpolated axis (front slides).
- Outside diameter grooving (cylindrical, taper, barrel faced rings), chamfering, "napier" shaping or any other operation made by nr. 2 interpolated axis (rear slides).
- Automatic loading and unloading of the piston rings.
