Technical Description

The Okuma LB3000 EX II MYW is a horizontal CNC turning center in the Okuma LB3000 EX II series, built with a main spindle, a Y-axis, rotary milling tools on the turret and an opposed sub-spindle. The BB designation marks the Big-Bore main spindle, which has a JIS A2-8 nose, a 91 mm (3.58 in) bore and a speed range of 42 to 4,200 rpm, driven by a 30/22 kW (40/30 hp, 30 min/continuous) motor with two automatic speed ranges. Swing over the bed is 580 mm (22.83 in) and the maximum turning diameter on the MYW version is 340 mm (13.39 in). The sub-spindle turns to 6,000 rpm with a 62 mm (2.44 in) bore and an 11/7.5 kW motor. A 12-station M-V12 turret carries both turning tools and driven milling tools, with a milling spindle speed of 45 to 6,000 rpm and a 7.1/4.1 kW milling motor. Travels are 260 mm in X and 115 mm in Y, and the C-axis indexes in 0.001 degree increments. Rapid traverse is 25 m/min in X, 30 m/min in Z and 12.5 m/min in Y. The machine is offered with ×450 and ×800 distance-between-spindle options, which set its floor space, height and mass. It is controlled by the Okuma OSP-P300LA CNC.
