2006 OKUMA L470BBM CNC LATHES

Technical Description

The Okuma Captain L470BBM is a Big Bore configuration CNC turning center from Okuma's Captain L-series, built to accommodate large-diameter bar stock and thick-walled tube or pipe workpieces through an oversized through-spindle bore. The machine carries a single main spindle using an A2-11 spindle nose, a mounting standard associated with Okuma's larger-capacity Big Bore spindle cartridges, with the spindle rated for a maximum rotational speed of 3,000 rpm. Tooling is held in a 12-position turret, and the machine is operated with Okuma's OSP-E100L CNC control; both figures are reported consistently across separate dealer listings describing different individual L470 Big Bore family machines. Okuma's Captain L-series Big Bore lathes of this generation were marketed to shops producing large hydraulic cylinder bodies, flanges, couplings, and similar parts requiring bar or tube feed-through beyond the capacity of a standard-bore spindle. Okuma offered the L470 Big Bore platform across more than one bed-length (distance-between-centers) configuration, and because the specific bed-length variant of this unit could not be confirmed, figures that vary by bed length — swing diameter, maximum turning length, spindle bore diameter, chuck size, spindle motor rating, and machine weight — are not reported here.
