The used Doosan BM 2740 is a large double-column (bridge-type) CNC vertical machining center engineered for machining very large and heavy components with high rigidity and precision. It is part of the BM series, designed specifically for industries requiring stable machining over long travels such as aerospace, energy, mold & die, and heavy equipment manufacturing.
This machine features a fixed cross-rail double-column structure combined with LM roller guideways and a high-torque built-in spindle. The design minimizes vibration and ensures consistent accuracy across the full machining envelope. It is well suited for both heavy roughing and precision finishing of large plate materials and structural components.
When purchasing a used BM 2740, it is critical to evaluate spindle condition, alignment across long axis travels, table wear, and tool changer reliability, as these machines are typically used in high-load production environments.
