The used Doosan BM 2740M is a large double-column (bridge-type) CNC vertical machining center designed for high-precision machining of very large and heavy components. It is part of the BM series and is specifically built for industries that require long travel accuracy, structural rigidity, and consistent performance across large work envelopes.
This machine features a rigid fixed cross-rail double-column structure, combined with LM roller guideways and a high-performance built-in spindle. The BM 2740M is equipped with a 12,000 RPM, 30 kW spindle designed for both heavy roughing and fine finishing, while minimizing vibration through a face-and-taper spindle interface.
It also incorporates thermal compensation systems and linear scales on all axes to maintain precision during long machining cycles, making it highly suitable for demanding industrial applications.
When purchasing a used BM 2740M, it is important to inspect spindle condition, axis alignment across full travel, table flatness, and ATC performance due to the heavy-duty nature of its applications.
