What to Look for When Buying a Used Komo
Komo CNC routers are built from heavy welded steel tube frames, precision-ground linear guideways, and Fanuc HVI servo systems. Many Komo VR and Mach III machines from the late 1990s and 2000s are still in daily service. Here is what to verify before buying a used unit.
Inspect the spindle, ATC, and bearings. Komo spindles run 18,000 to 24,000 rpm on VR series and 24,000 to 30,000 rpm on Mach III and Fusion machines. HSK 63F, HSK 50, and ISO 30 are common interfaces. Check spindle runout, listen for bearing noise at full rpm after warm-up, and test air blast and coolant-through functions. Cycle the ATC through every pocket. On twin-spindle Mach III units, verify both spindles independently.
Check the vacuum table, frame, and linear guides. Inspect the aluminum vacuum sub-surface for warping, gouges, and broken zones. Test each zone under load and confirm the pump pulls proper CFM. Check linear guides and ball bearing trucks for smooth travel. On moving-table configurations, check the rack and pinion drive on the X axis for gear wear and lash.
Verify ballscrews, rack & pinion, and servo tuning. Y and Z axes use pre-loaded precision ballscrews with Fanuc Alpha HVI servos. Long X travel is usually rack and pinion on Fusion and VR models. Measure backlash on Y and Z, and run a test cut to confirm surface finish and positioning repeatability. On 5-axis Fusion platforms, verify A/C rotary head calibration and axis clamps.
Identify the Fanuc control generation. Common combinations: Fanuc 0-M and 16i on 1990s VR machines, 18i and 21i on early 2000s VR Mach II, 210i-M on later VR Mach II SHO, and 31i or 32i on current Fusion and Mach III platforms.
Komo CNC Router Series
Fusion Series (VR, Twin Table, 5-Axis)
The Fusion VR is Komo's current flagship 3-axis router with a moving-table fixed-gantry design and vacuum table work surface. The Fusion Twin Table supports pendulum processing. The Fusion 5-Axis adds multi-axis capability with 36" or 48" Z travel for aerospace composites, foam patterns, and 3D parts. Standard spindle: 18 HP, 24,000 rpm, HSK 63F, with 15-position ATC.
Mach III Series (VR510, VR512, VR810)
The Mach III is Komo's premier router series for shops needing larger tool changers and extended Z travel. Moving-table configurations with at-spindle tool changers are standard. Twin-spindle setups are common, with dual 24,000 or 30,000 rpm HSK 50 or HSK 63F spindles and Fanuc Panel i controls.
Xtreme, Solution & VGM Series
The Xtreme offers core Komo build quality at an entry-level price. The Solution is configurable in bed length and width for non-standard work envelopes. The VGM is Komo's heavy-duty platform for ferrous and non-ferrous metals in addition to wood, plastic, and composites.
Legacy VR Series (VR-508, VR-510, VR-512, VR-810)
Older VR-series routers remain the most commonly traded on the used market. The VR-508 (5' x 8'), VR-510 (5' x 10'), VR-512 (5' x 12'), and VR-810 ship in Mach II, Mach II SHO, and Mach III configurations. Typical specs: cast-aluminum moving tables, single or dual vacuum zones, 12 to 18 HP spindles at 18,000 rpm, ISO 30 or BT 30 tapers, 8-position carousel ATCs, and Fanuc 0-M, 16i, or 210i-M controls.
How to Sell Your Used Komo
Komo routers hold strong resale value thanks to American build quality, heavy steel frames, Fanuc control standardization, and 20+ year production life. Fusion, Mach III twin-spindle, and VR-512 Mach II / III platforms are in particularly high demand.

Frequently Asked Questions About Used Komo Machines
Is Komo still in business?
Yes. Komo Machine, Inc. operates from Sauk Rapids, Minnesota as a subsidiary of PMC Global, Inc. Komo manufactures CNC routers in the USA and supports nearly 4,000 installed machines with parts, service, and support.
Are used Komo routers reliable?
Yes. Welded steel tube frames, precision linear guides, and Fanuc servos give Komo machines a long production life. Many 1990s and early-2000s VR routers are still running in daily production.
What should I inspect before buying a used Komo router?
Check spindle runout and bearing noise, cycle the tool changer through every pocket, test each vacuum zone under load, inspect the table surface for warping, verify linear guide wear and ballscrew backlash on Y and Z, and examine rack and pinion condition on the X axis.
What Komo models hold their value best?
Fusion VR, Fusion Twin Table, Mach III twin-spindle (VR510 / VR512 / VR810), and VR-512 Mach II SHO platforms. 5-axis Fusion machines command a premium in aerospace composite work. Call (844) 478-8181 for valuations.
Can I still get parts for older Komo VR routers?
Yes. Komo supports legacy VR, Mach II, and Mach III routers with parts and service from Sauk Rapids, MN. Fanuc controls, spindle drives, and vacuum components are also broadly supported through the standard CNC parts ecosystem.
Does Komo make metal-cutting machining centers?
Komo's current focus is CNC routers for wood, plastic, and composites, plus the VGM series for metals. Legacy Komo VMCs from the 1984 to mid-1990s line still show up on the used market.
