We service the Doosan and DN Solutions platforms running on Midwest shop floors — Puma horizontal turning, Lynx compact lathes, DNM verticals, NHM horizontals, DVF 5-axis, and the multitasking Puma MX and SMX lines. Find your model below, or browse by series, control generation, or service type.
Browse by Series
Pick the Doosan platform you run for failure patterns specific to that series.
- Puma — Horizontal turning. Puma 230 through 800, with M/MS/LM/Y/SY variants and TT/GT/TW builds.
- Puma MX / SMX — Mill-turn multitasking. MX 1600 through 3100 and SMX 2100/2600/3100.
- Puma V / VT / VTR — Vertical turning. Puma V400 through V9300 chuckers and VT/VTR ram-type.
- Lynx — Compact turning. Lynx 220 through 300, M/MS/LM/LSY and similar variants.
- DNM — Vertical machining. DNM 200 through 750, plus the DNM 200/5AX 5-axis variant.
- Horizontals (NHM / NHP / HC) — Production horizontals. NHM 4000 through 8000, NHP 4000 through 6300, HC 400/500.
- DVF / FM 5-Axis Verticals — 5-axis trunnion verticals. DVF 5000/6500/8000 and FM 200/5AX Linear.

What brings Doosan machines in for repair
Most Doosan repair calls fall into a few patterns: turret indexing on Puma and Lynx lathes, sub-spindle alignment on SY/SMC twin-spindle variants, B-axis milling spindle wear on Puma MX/SMX multitasking, pallet-changer faults on NHM horizontals, and trunnion calibration on DVF 5-axis. Control-side, Doosan ships almost exclusively on Fanuc — most of the work centers on Fanuc 0i for entry and mid-range builds and Fanuc 30i for higher-end multitasking and 5-axis.
How we approach Doosan repair work
Doosan service starts with confirming the model and the Fanuc control generation. Fanuc 0i (Series 0i-A through 0i-F) covers entry and mid-range Puma, Lynx, and DNM. Fanuc 30i (30i-A and 30i-B) covers higher-end Puma, Puma MX/SMX, DVF, NHM, and the larger DNM 4000/5700/6700 builds. Once the control is identified, the mechanical work follows the series patterns.
Lead Time & Process
Lead time on machine repair depends on what's wrong — diagnostic is fast, but parts and rebuild time vary by the job. Our three-step workflow keeps it transparent:
- Contact us. Call 319-610-4341 or use the quote form. Tell us the machine, the symptoms, and how urgent it is.
- Review & quote. We confirm the model and control generation, scope the work, and send back a price and realistic lead time within one business day on most inquiries.
- Approve & rebuild. We complete the repair, verify it back to spec, and return the machine ready to run.
Why Shops Trust Us
Experienced field technicians with hands-on time across the major CNC OEM platforms, in-house precision spindle balancing capability, laser alignment services, and established relationships with aftermarket bearing and spindle component suppliers.
"Honestly, we thought the machine was done for." Most customers tell us they're relieved to avoid replacement lead times and six-figure capital expenses.
Frequently Asked Questions
What can you fix on a Doosan CNC machine?
Turret and sub-spindle work on Puma and Lynx lathes, B-axis spindle and ATC on Puma MX/SMX multitasking, ATC and ballscrew on DNM verticals, pallet changer on NHM horizontals, trunnion calibration on DVF 5-axis. We diagnose before we quote.
Which Doosan series do you see most often?
The Puma horizontal turning workhorse is the most common Doosan platform on Midwest shop floors — particularly the 2100, 2500, and 2600 sizes. Lynx compact lathes are next, then DNM verticals. Puma MX/SMX multitasking and DVF 5-axis are higher-value but lower frequency.
Do you service older Doosan machines with Fanuc 0i-C or earlier?
Yes. Doosan ships almost exclusively on Fanuc, so older Doosan machines with Fanuc 16i, 18i, 21i, or 0i-A/B/C controls are routine work. The common issues are PCMCIA media obsolescence, FROM/SRAM battery loss, drive amplifier faults, and monitor failure.
What's the difference between a Doosan branded machine and a DN Solutions branded one?
DN Solutions is the current corporate name for the same lineup. Pre-rebrand machines say 'Doosan'; post-rebrand machines say 'DN Solutions.' The hardware is the same and the service work is the same.
How long does a typical Doosan machine repair take?
Lead time depends on what's wrong. Diagnostic is fast; parts and rebuild time vary by the job. Fanuc-side work on older controls depends on Fanuc parts availability and PCMCIA media migration; mechanical work runs 3 to 5 weeks on most jobs.
Do you service Doosan machines outside Iowa?
Yes. We service shops across Iowa, Illinois, Wisconsin, Minnesota, Nebraska, Missouri, and Texas.
