2005 OKUMA L370M CNC LATHES

Technical Description

The Okuma Captain L370M is a CNC turning center from Okuma's Captain L-series of slant-bed lathes, fitted with live tooling (the "M" designation) that enables turning, drilling, and milling operations to be completed in a single workholding setup, reducing part handling and improving dimensional consistency between operations. The machine carries a single main spindle and a 12-position turret for tool storage, a turret configuration reported consistently across multiple independent used-equipment listings describing separately sold L370M units. Its turning envelope supports a maximum workpiece turning diameter of approximately 13.38 inches and a maximum turning length of 20.47 inches, figures that match between listings describing different individual machines built during the model's early-to-mid 2000s production run, which spans the subject 2005 unit. The spindle reaches a maximum rotational speed of 3,800 rpm, also consistent between separately listed machines. Okuma built the Captain L-series for small-to-medium shops producing shaft, flange, and housing-type turned parts, where the L370M's live tooling allows secondary milling, drilling, and cross-hole operations without transferring the part to a second machine. Spindle motor rating, spindle bore diameter, chuck size, control system version, and overall machine weight differed between the specific listings reviewed and are not reported.
