What the maker publishes about the current Okuma LB35III

Okuma's LB35III is a large horizontal lathe with one saddle, part of the LB series. Parts turn to Ø18.11 in. The base bed turns 23.62 in of length. Longer beds raise that figure to 33.46, 59.06 or 78.74 in. The standard spindle nose is A2-8, while A2-11 and A2-15 noses appear as alternatives. The base speed band is 14 to 3,200 min⁻¹. The alternative spindles run 12 to 2,800 min⁻¹ and 40 to 1,400 min⁻¹. Rated power is 40/30 hp as standard. The alternative rating is 50/40 hp. X and Z rapid at 591 and 787 ipm respectively. The C-axis rapid rate is 100 rpm. Tools sit on an NC turret that indexes fast. The optional M configuration adds live tooling for drilling, milling and tapping alongside turning. The OSP suite comes with its apps already installed. Okuma also lists rotary tooling and long bed versions for the series.

What to check on an Okuma LB35III

• Control generation. The manufacturer specifies OSP-P500 for this model. Units we have tracked run 2016 to 2021; an early one may carry an older control or a retrofit.
• Spindle. The manufacturer gives a spindle speed of 14~3,200 [12~2,800; 40~1,400] min⁻¹. Run the spindle to top speed and listen for bearing noise.
• Spindle load. The manufacturer gives 30/22 [37/30] kW (40/30 [50/40] hp) of spindle power. Take a heavy cut and watch the load meter.
• Spindle nose. The manufacturer gives a spindle nose of A2-8 [A2-11, A2-15]. Check that the chuck fitted to it runs true.
• Rapids and ballscrews. The manufacturer gives a rapid traverse of 15 / 20 [C: 100 rpm] m/min (591 / 787 [C: 100 rpm] ipm). Measure the backlash on each axis.
• Bed and ways. The manufacturer gives a max turning diameter of Ø460 mm (Ø18.11 in) and a max turning length of 600 [850; 1,500; 2,000] mm (23.62 [33.46, 59.06, 78.74] in). Check the ways for wear near the chuck.

Okuma LB35III control and manuals

• Control OSP-P500

In a 2024 video, Okuma says its OSP control holds the machine manuals already loaded, so an operator can open them at the machine, and that other PDF files load onto it from a USB drive.
