Doosan CNC machines are built by the South Korean company now called DN Solutions, which began as the machine tool business of Daewoo Heavy Industries and carried the Doosan name from 2005 until 2022. Its main lines include the PUMA and Lynx turning centers, the DNM and Mynx vertical machining centers, the NHP and NHM horizontal machining centers and the SMX mill-turn machines. This guide explains each line, shows how to read the letters in a Doosan lathe model name, and lists what to note when you identify one.
Machine Tool Exchange buys used Doosan machines directly from the shops that own them, so the guide ends with the details an owner needs on hand.
Daewoo, Doosan, DN Solutions: One Company, Three Names
A Doosan machine may carry a Daewoo, Doosan or DN Solutions badge, because the same business has gone by all three names. DN Solutions' own history gives the timeline:
- 1976: Daewoo Heavy Industries completed its machine tool factory.
- 1980: it independently developed an NC lathe, the PUMA 10, so the PUMA name goes back to 1980.
- 1983: it began producing NC machining centers.
- 1994: it set up a US subsidiary, Daewoo Machinery Corp.
- 2005: the company was renamed Doosan Infracore.
- 2016: the machine tool business became Doosan Machine Tools.
- 2022: it was renamed DN Solutions in May.
The 2022 rename followed the company's acquisition that year by DTR Automotive (now DN Automotive). DN Solutions is based in Changwon, South Korea. In January 2026 it completed the purchase of the German builder Heller, and in 2025 it opened a technical center in Chicago. If your machine wears a Daewoo plate, see our page for used Daewoo machines. For where Doosan sits among the other builders, see our guide to CNC machine brands and their history.
What CNC Machines Does Doosan Make?
DN Solutions builds turning centers, machining centers, boring mills, double-column machines, 5-axis machines and multitasking mill-turn machines, and says its lineup runs to more than 500 products. The main lines are these:
| Type | Doosan lines |
|---|---|
| Horizontal turning centers | Lynx, PUMA (2100 to 3100, 4100/5100, 600/700/800 II, 1000), PUMA GT, PUMA DNT, LEO 1600 |
| Twin-turret and twin-spindle lathes | PUMA TT, PUMA TL, PUMA TW |
| Vertical turning centers | PUMA V400, PUMA VT, PUMA V8300/9300, PV 6300, PUMA VTR (ram type) |
| Swiss-type | PUMA ST GS II |
| Multitasking mill-turn | SMX, DNX |
| Vertical machining centers | DNM, Mynx II, DEM, BVM, SVM, VM, VC, VCF, GVX |
| Tapping centers | T, VC |
| Horizontal machining centers | NHP, NHM, NHC, HC II, HM |
| 5-axis | DVF, DNM 5AX, FM 5AX, DHF |
| Boring mills and double-column | DBC, DBD; BM, DBM, DCM |
Doosan Lathes and Turning Centers
DN Solutions sorts its horizontal turning centers by what the machine can do: two-axis, with milling, or with a Y axis. The PUMA and Lynx lines appear in all three groups.
- Lynx: DN calls the Lynx 2100/2600 series "6"~10" High Performance Compact Turning Center" machines with "a small footprint." The Lynx is Doosan's compact line.
- PUMA 2100, 2600 and 3100: a series DN describes as a "High Performance Y-axis Horizontal Turning Center," built in two-axis, milling and Y-axis versions. The PUMA 4100/5100, 600/700/800 II and 1000 series continue the range.
- PUMA GT: DN's "8"/10"/12" Global Standard Turning Center," a heavy-duty standard turning center with a box guideway structure.
- PUMA TT and TW: DN calls the TT a "Twin-spindle Twin-turret with Y-axis Turning Center" with live tooling and a built-in sub-spindle, though its table lists no Y-axis travel for the MS models; the TW has "twin parallel spindles and twin turrets," with live tooling on its M models.
- PUMA V, VT and VTR: vertical turning centers. The PUMA V8300/9300 is a heavy-duty model that accepts chucks "from 15" up to 32"." Our guide to vertical turret lathes explains how these machines work.
For how turning centers differ from plain lathes, see our page on used turning centers.
How Do You Read a Doosan Lathe Model Name?
A Doosan lathe model name is the line, a size number and, on many models, letters for the configuration. DN Solutions' own spec tables show what the letters do:
| Part of the name | What it means | Example from DN's tables |
|---|---|---|
| The number | The size within a series: a bigger number is a bigger machine | PUMA 2600 takes a 10 in. chuck; PUMA 3100 a 12 in. chuck |
| L | Longer turning length | PUMA 2600: 790 mm; PUMA 2600L: 1,310 mm |
| XL, UL | Longer again | PUMA 3100XL: 2,150 mm; PUMA 3100UL: 3,150 mm |
| A, B, C | Chuck size steps within a model | Lynx 2100A: 6 in.; 2100B: 8 in.; 2100LC: 10 in. |
| M | Milling (live tooling) | Listed under "Horizontal with Milling," for example the PUMA 4100LMA |
| Y | Y axis | Listed under "Horizontal with Y-axis," for example the PUMA 5100LYA |
| S | Sub-spindle | The Lynx 2600SY has a main spindle and a sub-spindle, plus a Y axis |
On the PUMA 2600, the B also means a bigger chuck: the PUMA 2600B takes a 12 in. chuck against the 2600's 10 in. Letters combine, so a PUMA 2100LSY is a long version with a sub-spindle and a Y axis. Some older Doosan and Daewoo lathes use three-digit numbers, such as the PUMA 250B, with the same kind of letters after them. The numbers only compare within a series: DN's current PUMA 600 II takes an 18 in. chuck, larger than the PUMA 3100's 12 in. Letters can mean different things on different lines, so check the spec sheet for your exact model.
Doosan Multitasking Machines: SMX and DNX
The SMX and DNX are Doosan's multitasking mill-turn machines, which add a milling spindle on a B axis to a lathe. DN calls the SMX a "High Performance Multi-axis Mill Turn Machine" and says the series has "a total of nine axes." Its fullest versions combine "the left and right spindles, the B-axis milling function and a lower turret," while some SMX models have a single spindle. DN says the SMX takes "larger chuck sizes than PUMA MX machines"; the PUMA MX is an earlier Doosan multitasking line that does not appear in DN's current lineup. The DNX is "a compact multitasking machine" with a milling spindle on a B axis, and its S models add a second spindle.
For how a B axis, a sub-spindle and a second turret add up, read our guide to multi-axis lathes.
Doosan Machining Centers: DNM, Mynx, NHP and More
On the milling side, the main lines are these:
- DNM: vertical machining centers. DN calls the DNM series "a popular and proven mainstay" with "a global installed base in excess of 30000 machines." See our page for used vertical machining centers.
- Mynx II: DN's "Mid-to-large-sized Heavy Duty Machining Center" line, for heavy milling.
- NHP and NHM: horizontal machining centers. DN describes the NHP as a "High Productivity Horizontal Machining Center" with an automatic pallet changer. See our page for used HMCs.
- DVF: 5-axis vertical machining centers with a 2-axis tilting table. See our page for used 5-axis machines.
- DBC: DN's "Medium to large-capacity Horizontal Boring Mill." See our page for used boring mills.
Which Control Does a Doosan Have?
FANUC controls appear across the Doosan range, but check the machine rather than assuming. A few examples:
- DN Solutions lists a FANUC control on its T 4000 tapping center.
- Modern Machine Shop reported the Lynx 2600SY with FANUC's 0i-TF Plus and Doosan's EZ Guide conversational programming, which keeps G-code programming.
- The DVF 5000 Second Generation can be ordered with FANUC, HEIDENHAIN or SIEMENS controls.
Some newer machines, including the SMX and the NHP and NHM horizontals, can carry CUFOS, which DN Solutions describes as "a PC based control system created by DN Solutions." Its screen can be switched "to standard FANUC format." The control maker, model and software version are on the control itself.
What to Note on a Doosan You Own
To describe a Doosan accurately, collect these details from the machine:
- Model and serial number, from the data plate. A photo of the plate is more reliable than memory.
- The badge: Daewoo, Doosan or DN Solutions.
- Control maker, model and software version, and whether it has a CUFOS screen.
- Spindle hours, which can often be read off the control.
- Configuration: chuck size, turning length, live tooling, Y axis and sub-spindle on a lathe; table size, taper and pallets on a machining center.
- Attachments: bar feeder, parts catcher, tool presetter, chip conveyor and any tooling that goes with it.

Frequently Asked Questions
Is Doosan the same as DN Solutions?
Yes. Doosan Machine Tools was renamed DN Solutions in May 2022, after DTR Automotive (now DN Automotive) acquired it. The product lines carried on under the new name, so a DN Solutions PUMA or DNM belongs to the same lines as a Doosan-badged one.
Who makes Doosan CNC machines today?
DN Solutions, a machine tool builder based in Changwon, South Korea, and a subsidiary of DN Automotive. It began in 1976 as the machine tool business of Daewoo Heavy Industries and went by the Doosan name before 2022.
What is the difference between a Doosan PUMA and a Lynx?
The Lynx is Doosan's compact turning center line; DN lists the Lynx 2100/2600 series for 6 to 10 in. chucks. The PUMA name covers most of the rest of the horizontal turning range, from the PUMA 2100 to 3100 series up through the 4100/5100, 600/700/800 II and 1000 series, plus the GT, TT, TW and vertical PUMA V lines.
What do the M, Y and S mean on a Doosan lathe?
In DN Solutions' lineup, M models are listed as horizontal turning centers with milling (live tooling), Y models have a Y axis, and S marks a sub-spindle. The letters combine, so an SY model has a sub-spindle and a Y axis.
Are Daewoo lathes the same as Doosan lathes?
They come from the same business. Daewoo Heavy Industries developed the PUMA 10 NC lathe in 1980, and the company was renamed Doosan Infracore in 2005. That is why older PUMA lathes often carry a Daewoo badge.
