Doosan DNM 4500 Bed Type CNC Mill from China

The Doosan DNM 4500 is a high-speed bed type vertical machining center for milling complex metal parts with excellent rigidity from its box-way bed design. Classified under HTS 8459.69.0070 for bed type milling machines, it's used in producing precision components for semiconductor crystal grinders and polishers. The fixed bed ensures vibration-free operation critical for semiconductor fab tool manufacturing.

Import Tips

Document CNC control systems and axis configurations to confirm milling function dominance over other operations

For semiconductor-related imports, provide proof of use in wafer prep equipment to support Chapter 84 statistical note applicability

Avoid pitfalls by labeling as 'bed type' explicitly; misdescription as 'vertical spindle' can lead to 8459.40 classification errors
