The Okuma LT2000EX-2T2MY is a twin-spindle, twin-turret CNC turn-mill center known for the thermal stability and done-in-one reliability that made the LT EX series a staple in high-mix production and precision machining shops. This 2022 unit runs two opposed main spindles - a big-bore A2-6 left spindle with an 80 mm (3.15 in) bore and 65 mm (2.56 in) bar capacity, both spindles driven by upgraded 30 HP (22 kW) motors - paired with dual Multitasking V16 turrets carrying 16 tool stations each, live tooling on both turrets, full C-axis, and Y-axis travel for true milling, drilling, and tapping on either end of the part. The work envelope covers a 400 mm (15.75 in) swing, 350 mm (13.78 in) max turning diameter, and 200 mm (7.88 in) turning length, with X and Z travels of 205 mm (8.07 in) and 700 mm (27.56 in) and rapid traverse of 30 m/min in X and 40 m/min in Z. Main spindle speeds reach 6,000 rpm (5,000 rpm on the big-bore spindle), live tooling turns to 6,000 rpm at 7.5 HP, and the machine runs Okuma's OSP control with high-pressure coolant, Renishaw in-process probing, and an Edge bar feeder for automated, lights-out turning of finished parts.
Set against the previous-generation Okuma LT200 / LT200-MY it replaced, the LT2000 EX is a meaningfully better machine, not just a newer one. Okuma stepped up from the older OSP-P200-class control to the current OSP platform with collision avoidance and thermal-compensation intelligence, adopted the Thermo-Friendly Concept for tighter all-day accuracy, and pushed rapids to 30/40 m/min for shorter cycles. The EX generation also brought higher-capacity Multitasking V16 turrets, a big-bore A2-6 spindle option, and stronger twin-turret Y-axis capability, so both turrets can mill and turn on both spindles at once - work the earlier LT200 could not balance as efficiently. For a shop moving up from an LT200 or an older single-turret gang lathe, this 2T2MY delivers more tools in the cut, more rigidity, and genuine done-in-one production of complete parts.
