What to Look for When Buying a Used Doosan
Doosan is among the most commonly traded used CNC brands in North America thanks to high production volumes, durable Meehanite construction, and Fanuc control support spanning 20+ years.
On turning centers, check spindle, turret, and ways. Measure spindle runout at the nose (target under 0.0002" TIR) and verify the bar bore for wear. Doosan uses BMT turrets sized BMT45 through BMT85; older Daewoo-era Puma 240 and early Lynx machines use a proprietary 72 x 45 mm pattern, not true BMT, so verify before sourcing tooling.
On VMCs and HMCs, verify spindle, ATC, and way covers. DNM uses CAT 40 Big Plus; Mynx splits into /40 and /50 (CAT 50 geared-head) variants; DVF 5-axis uses CAT 40 Big Plus or HSK-A63. Measure drawbar pull force, inspect the taper for fretting, and cycle the ATC. Chip-damaged way covers are the primary cause of premature ball-screw failure.
On 5-axis DVF, verify trunnion calibration. Rotate the trunnion manually (servo-off) to feel for lost motion. Use a ballbar or AxiSet to check pivot-point alignment. Confirm thermal and Kinematic Compensation parameters are enabled.
Doosan Turning Centers
Puma Series (Flagship Turning)
The Puma series is Doosan's flagship 2-axis horizontal turning platform: Meehanite cast beds, box-way construction, chuck sizes 8" to 32". The Puma 2100 (8" chuck) and Puma 2600 (10" chuck) are the most commonly traded Doosan lathes. Sub-variants add long bed (L), live tools (M), Y-axis (Y), sub-spindle (S), or combined capability. Puma 3100-5100 handle larger work; Puma 600-800 target oil, gas, and large shaft machining.
Lynx Series (Compact Turning)
The Lynx series (220, 2100, 2600) is Doosan's compact entry-tier line with over 25,000 units sold globally. Linear roller guideways, 6" to 10" chucks, and smaller footprints make Lynx a job-shop favorite. M and LY variants add BMT45 live tooling and Y-axis.
Puma MX, SMX, TT & VT Specialty
Puma MX and SMX add B-axis milling spindles plus Y-axis and sub-spindle for complete part machining. Puma TT twin-turret twin-spindle targets high-volume automotive and medical. Puma VT/VTS vertical turret lathes handle 24" to 63" chucks.
Doosan Machining Centers
DNM Vertical Machining Centers
The DNM series is Doosan's best-selling VMC with over 30,000 units sold worldwide. Roller LM guides, CAT 40 Big Plus, 8,000-15,000 rpm spindles. Popular models: DNM 500, DNM 4500, DNM 5700, DNM 650, and DNM 6700.
Mynx & VCF Series
The Mynx series (5400, 6500, 7500, 9500) uses heavier box-way construction with CAT 40 or CAT 50 geared-head variants. The VCF bridge series (850, 850L, 850LSR) handles die, mold, and aerospace work with optional tilting B-axis head.
NHM Horizontal Machining Centers
The NHM series (4500, 5000, 6300, 8000): BT 50 taper, 60-tool ATC expandable to 376, pallet sizes 400-800 mm. The NHM 6300 is the most commonly traded size. The newer NHP series uses BT 40 for higher-speed aerospace and medical work.
DVF 5-Axis & Heavy Machines
The DVF series (5000, 6500, 8000, 8000T) is Doosan's trunnion 5-axis platform with AWC options. The DVF 5000 holds strong resale value. DBC boring mills (110, 130, 250) and DBM/DCM double-column bridge mills round out the heavy lineup.

Frequently Asked Questions About Used Doosan Machines
Is Doosan the same as DN Solutions?
Yes. Doosan Machine Tools renamed itself DN Solutions on June 2, 2022. The same Changwon, South Korea factories produce the same Puma, Lynx, DNM, Mynx, NHM, DVF, and DBC machines.
Is Doosan the same as Daewoo?
Historically yes. The business launched in 1976 as Daewoo Heavy Industries' machine tool division. Doosan Group acquired it in 2005; machines built before roughly 2005-2007 carry Daewoo badging. A Daewoo Puma is the direct ancestor of today's DN Solutions Puma.
Are used Doosan machines reliable?
Yes. Many 15 to 20-year-old machines remain in daily production. Meehanite castings, box-way construction on Puma lathes, and Fanuc controls with 20+ year supportability drive the brand's durability.
What CNC control does Doosan use?
Predominantly Fanuc. Entry and mid-tier machines use Fanuc 0i-TF (turning) or 0i-MF (milling). Higher-spec machines use Fanuc 31i-B or 31i-B5. Doosan overlays Fanuc with its proprietary iHMI. Siemens 840D and Heidenhain TNC 640 are optional.
What is the difference between Puma, Lynx, DNM, and Mynx?
Puma is the flagship box-way lathe (8"-32" chucks). Lynx is the compact linear-guide lathe (6"-10" chucks). DNM is the mainstream roller-guide VMC with CAT 40 Big Plus. Mynx is the heavier box-way VMC with optional CAT 50 geared head.
What Doosan models hold their value best?
DNM 500, 4500, 5700, and 6700 VMCs, Puma 2600 SY and MS variants, DVF 5000, and NHM 6300 HMCs maintain strong resale values. Call (844) 478-8181 for current valuations.
