A new, universal lathe for turn-milling chuck, bar and shaft parts in medium to large batches has been introduced by the Japanese manufacturer, Okuma, and is available in the UK through sole agent, NCMT. Capacity of the machine is 200 mm diameter for chucking, bar work up to 65 mm and 700 mm maximum shaft length.
 
The LT2000-EX has two opposing C-axis spindles and three turrets moving in X, Y and Z, making a total of 11 CNC axes. Complex components may be produced complete in one hit, speeding floor-to-floor time and improving accuracy. Y axis stroke is 95 mm.
 
All three turrets can be assigned to machine components at either spindle. Each turret has 16 live positions with up to 5.5 kW driven tool power in the range 50 to 6,000 rpm, maximum torque being 22.5 Nm. Alternatively the lathe is available with 12-station turrets and 31.3 Nm for heavier duty work.
The C-axes are positioned to an accuracy of 0.001 degree. Both spindles are rated at 22kW / 6,000 rpm / 350 Nm and can synchronously transfer a component at any spindle speed. This saves non-cutting time, a goal furthered by 30m/min and 40m/min rapids in X and Z respectively, and tool-to-tool turret indexing in 0.3 second.
 
Designed for round-the-clock production, the compact LT2000-EX will most likely be delivered with a gantry loader or bar feeder. Okuma's own control system, OSP-P200L, offers an open platform for data communication and operation, Windows-compatible applications, VBA-API, and interfaces including USB and Ethernet.
