1- ROMI G 550M

 

Turning Centers ROMI G 550 and G 550M (driven tools), equipped with CNC SIEMENS 828D, show high productivity, stiffness, torque and accuracy for machining in low and high production environments. Rough structure, with monoblock bed, longitudinal and transversal carriage supported on hardened and ground guides, making G 500 Series ideal for machining large size parts.

With 45.7 HP main engine, torque up to 2,310 N.m, it is possible to obtain remarkable productivity gains, due to the large capacity of material removal.

The model ROMI G 550M with driven tools allows the complete machining of a part in a single machine, because it also performs drilling and milling operations.
