The Okuma MacTurn550 is a multifunction turning center including an automatic tool changer, an automatic tow-along tailstock and lower turret. The MacTurn550 has the broadest scope of machining functions of any Okuma CNC machine in the 12-18 inch chuck class. MacTurn is the embodiment of power, speed, and process flexibility. Complete the work in one setup and with tools to spare in the ATC.      The MacTurn has two independent turrets that can machine independently or simultaneously. The upper saddle carries a dual function spindle head with 10hp integral milling motor spindle. The base offering has 44-tools available via the traversing ATC. The upper turret has a 1-degree B-axis and compound motion Y-axis for machining flexibility. The main spindle is equipped with a full contouring C-axis (0.001deg incr). The lower turret completes the concept, bringing 12 additional turning stations and four-axis flexibility to the ultimate Okuma Lathe.
