2017 OKUMA MULTUS U3000BB-2S-1C CNC LATHES

Technical Description

The Okuma MULTUS U3000 is a B-axis head multitasking lathe built by Okuma Corporation (Oguchi, Japan), an 8-10 inch chuck-class machine in Okuma's current MULTUS U series. Per Okuma's published specifications, maximum turning diameter is 25.69 in (650 mm), spindle nose is JIS A2-6 [A2-8 big-bore option], spindle speed range is 50-5,000 rpm, and standard power is 30/20 hp (22/15 kW). The B-axis milling head swings through 240 degrees with a 12,000-rpm H1 milling spindle using CAPTO C6 tooling, rated at 30 hp intermittent. The base ATC holds 40 tools (80 optional), and the turret provides Y-axis travel of 9.84 in via a traveling-column design. This row's '-2S-1C' suffix indicates the twin-spindle, 1-C-axis configuration, consistent with the optional sub-spindle Okuma offers on the U3000 platform, and the '-BB' designation (big bore) corresponds to Okuma's 3.58 in bore option noted on comparable used listings. The current platform runs Okuma's OSP-P500 control; this 2017-built unit predates that control's release, so the control actually fitted is not confirmed and left blank.
