The used Doosan DBC 250 II is a large-capacity CNC horizontal table-type boring mill designed for machining extremely large and heavy components with high precision. It represents one of the bigger machines in the DBC series, built for applications requiring both high-speed spindle performance and heavy-duty cutting capability.
This machine features a 250 mm class spindle system, a rigid box-type structure, and a high-capacity rotary table with full B-axis indexing. It allows multi-face machining in a single setup, significantly improving productivity and alignment accuracy for large workpieces. Its high-speed built-in spindle and long axis travels make it suitable for both roughing and precision finishing.
When buying a used DBC 250 II, key inspection areas include spindle condition, quill wear, rotary table backlash, and axis accuracy over long travels, as these machines are typically used in demanding heavy industrial environments.
