2004 OKUMA LU400 CNC LATHES

Technical Description

The Okuma LU400 is a 4-axis CNC turning center in Okuma's LU series, built in the 10-15 inch chuck class with box-bed, box-way construction and two independently indexing turrets. Independent, corroborating sources describing this model confirm a maximum main spindle speed of 3,800 rpm. The platform uses three-point spindle bearing support and a crown-gear turret coupling on both turrets, consistent with Okuma's general description of this turning-center family. Main spindle motor power has been documented inconsistently across individually listed units — figures of 35 hp and 40 hp have each been reported — and could not be confirmed to a single, non-conflicting value, and is therefore not reported here. Maximum turning diameter, chuck size, spindle nose configuration, tool capacity, overall machine dimensions, and shipping weight have each been documented with internally inconsistent or single-sourced figures across available listings and could not be independently corroborated for this specific 2004-built unit. The LU400 should not be confused with Okuma's later GENOS L400 platform, which is a distinct, smaller two-axis turning center sold under a different model line.
