DOOSAN DNM 4500 VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a work envelope of 31.5 in (X) by 17.7 in (Y) by 20.1 in (Z), accommodating medium-sized parts. It is powered by a 20.0 HP spindle motor capable of reaching speeds up to 8,000 RPM, optimized for a range of machining materials and operations. The spindle has a CAT40 taper, a widely used standard with a 7/24 taper angle, providing a secure and precise tool interface beneficial for reducing chatter and improving tool life in high-speed machining. The machine is equipped with a 30-position automatic tool changer (ATC), facilitating efficient tool switching and reducing downtime. The worktable measures 17.7 inches in width and 39.4 inches in length, supporting 3-axis movement for versatile milling and drilling tasks. The machine logs indicate 9,848 hours of sub-plate power usage, with 3,954 total runtime hours and 3,591 hours dedicated to cutting, reflecting substantial operational use and experience in diverse applications. Designed for precision, the CAT40 taper and spindle speed provide a balance of rigidity and versatility suitable for machining metals, plastics, and composites. Typical machining parameters at 8,000 RPM enable effective cutting speeds with moderate feed and depth of cut settings for accurate and efficient material removal. The dimensions and power specifications suggest this machine fits well in industrial manufacturing environments requiring reliable 3-axis CNC milling operations with robust toolholding and high throughput.
