Most of the used Doosan DNMs KD Machinery has listed are CAT 40 vertical machining centers with a Fanuc control. KD Machinery buys and sells them from the 30-inch DNM 400 and 4500 up to the 85-inch DNM 750L, built from 2009 to 2024.
Used Doosan DNM
Three digits or four: matching the sizes
DNM model numbers changed during the years on KD Machinery’s record, and the older and newer machines line up by size. A DNM 400 and a DNM 4500 both have about 30 inches of X travel, a DNM 500 and a DNM 5700 about 40 inches, and a DNM 650 and a DNM 6700 about 50. Most of the three-digit machines KD Machinery has listed were built before 2017, and the four-digit ones from 2016 on. The DNM 750 and 750L, with 64 and 85 inches of X, are the long-table machines. Every DNM on KD Machinery’s record as of October 2026, the 2024 machine included, is listed under the make Doosan. Some of its newest Puma, Lynx and DVF listings carry the make DN Solutions instead, so if you search by make, try both names.
Spindle, taper and tool magazine
A 12,000 rpm spindle is common on the DNMs KD Machinery has listed, and many others have 8,000 or 15,000 rpm; 15,000 rpm shows up mostly on the newer 4500s and 5700s. CAT 40 is the usual taper, a few machines have CAT 40 Big Plus, and the one DNM 750L/50 on the record is 50-taper. Most have a 30-tool magazine, and some a 40. Through-spindle coolant and a chip conveyor are common but not universal, so check both on the listing.
The 5-axis machines
The DNM 200/5AX and DNM 350/5AX on KD Machinery’s record are five-axis machines with a trunnion table, built from 2015 to 2020; the 350/5AX listings name a Fanuc 31i control. They are smaller in X than the three-axis DNMs, so compare them with other five-axis machines rather than by travel.
What to check on a used DNM
Run the spindle at low and top speed and listen for bearing noise, and check the drawbar holds a tool firmly. Cycle the tool changer through every pocket. Move each axis its full travel and look under the way covers for chips and damage. If a fourth axis is included, run it; if not, ask whether the machine is wired for one, since several on the record are.
More Doosan machines and VMC pages
Every Doosan machine KD Machinery lists, lathes included, is on the Doosan manufacturer page. To compare a DNM with other makes, browse used CNC vertical machining centers or the used Hurco machining centers, and read the vertical machining center buying guide before you inspect one. The Doosan lathes have their own pages: Puma and Lynx 2100.
