Overview

The Okuma LB3000 EX II MY is listed as an LB3000 with a Y axis and driven tools on the turret. Y-axis travel is ±52.5 mm, the live tools run 50 – 6,000 rpm on a 3.7 / 5.5 kW (5 / 7.5 HP) motor, and the turret has 12 stations, given as VDI-40 or BMT-65. With that equipment a turned part can be cross-drilled, slotted and milled off-centre without leaving the chuck.

On the work side, the listed figures are a 254 mm (10 in) chuck, an 80 mm (3.15 in) bar capacity and a JIS A2-6 spindle nose. Rapid traverse is 20 / 24 / 12 m/min in X, Z and Y. The Y axis is the slowest of the three, which seldom matters because Y moves are short.

The rest of the table needs caution. The listed rows give more than one value for main spindle speed, main spindle power, swing, turning diameter and turning length, and they name two different controls. That pattern points to more than one configuration behind the figures. Take those values from the nameplate and build sheet of the specific machine, not from a summary.

For installation, the listed weight is approx. 6,500 kg (14,330 lb) and the floor space is 3,025 x 2,008 mm, width by depth.

Strengths & Limitations

Strengths

Y-axis travel of ±52.5 mm for off-centre milling and drilling
Live tools listed at 50 – 6,000 rpm with a 3.7 / 5.5 kW (5 / 7.5 HP) motor
12-station turret, listed as VDI-40 or BMT-65
Listed bar capacity of 80 mm (3.15 in) with a 254 mm (10 in) chuck

Limitations

Y travel of ±52.5 mm limits how far off centre a feature can be milled
Live tool power of 3.7 / 5.5 kW (5 / 7.5 HP) suits drilling and light milling, not heavy stock removal
Y-axis rapid is 12 m/min, against 20 and 24 m/min in X and Z
The listed rows disagree on main spindle speed, power and turning capacity, so those must be confirmed on the machine

Best For

Turned parts that also need cross holes, flats or keyways Off-centre milling within ±52.5 mm of Y travel Bar work up to the listed 80 mm (3.15 in) capacity Drilling and light milling with live tools at up to 6,000 rpm

Frequently Asked Questions

01 How much Y-axis travel does the LB3000 EX II MY have?

The listed Y-axis travel is ±52.5 mm. That is the distance either side of the spindle centreline over which a driven tool can mill or drill, and Y-axis rapid traverse is listed at 12 m/min.

02 What are the live tooling figures for the LB3000 EX II MY?

Live tool speed is listed as 50 – 6,000 rpm and the live tool motor as 3.7 / 5.5 kW (5 / 7.5 HP). Those figures fit drilling, tapping and light milling on turned parts.

03 What turret does the LB3000 EX II MY use?

A 12-station turret. The table gives the tooling interface as VDI-40 or BMT-65, so find out which one a particular machine has before buying holders, because the two are not interchangeable.

04 What main spindle speed and power does the LB3000 EX II MY have?

The listed rows do not agree. Main spindle speed and motor power each appear with more than one value, which suggests different spindle configurations. Read both from the nameplate of the machine in question; the spindle nose is listed as JIS A2-6.

05 How much floor space and weight should I plan for?

The listed floor space is 3,025 x 2,008 mm, width by depth, and the listed weight is approx. 6,500 kg (14,330 lb). Allow extra room around that footprint for door and service access.
