Verdict
Choose the Mazak INTEGREX e-420H for large shaft and housing work that needs heavy off-center milling, such as landing gear, turbine shafts and valve bodies, where 420 mm of Y travel and the 3,048 mm bed option matter. Choose the Mazak INTEGREX i-400 for bar-fed, lights-out production of medium-to-large parts, where its 102 mm bar capacity, longer Z stroke and 20,000 RPM option suit high-mix work stepping up from an i-200.
