About C.R. Onsrud
Who C.R. Onsrud isC.R. Onsrud, Inc. is a family-owned and operated manufacturer of CNC machining centers, CNC routers, CNC mills and inverted routers, built at its factory in Troutman, North Carolina. The company states that over 80% of its manufacturing is done in-house — engineering, welding frames, cutting sheet metal, machining steel and aluminum components, painting, assembly and quality control. The Onsrud family's history in machine tools goes back to 1915, when Oscar Onsrud and his son Rudolph invented and patented an air-powered high-speed spindle. In 1976 Charlie Onsrud patented the Inverted Router, and the company began building CNC machining centers in 1994 under current CEO Tom Onsrud.
What they buildOnsrud is best known for large-format, heavy-gauge CNC router and machining center platforms. Alongside the inverted routers, the current lineup is organized into 3-axis and 5-axis families, including the A-, M-, T-, G-, S-, RH-, C- and E-Series in 3-axis, and the G-, S-, C-, E-, CH-, HM-, LR-, Q-, X- and EX-Series in 5-axis. Machine sizes and options are configured per application. The company describes its machines as processing solid wood, advanced polymer plastics, composites and nonferrous metals — which is why they turn up in plastics fabrication, thermoforming and composite shops as well as woodworking plants. Frames, columns and bridges are thick steel for rigidity at high feed rates, and machines ship with FANUC controls plus Onsrud's own touchscreen HMI and SeeNC interface.
Model series used buyers search forThe C-Series is the heavy-duty fixed-bridge platform most often seen in resale listings, offered in 3-, 4- and 5-axis versions with single or twin spindles. Published C-Series details include twin table sizes from 4' x 5' up to 6' x 5' each (8' x 5' to 12' x 5' combined), Z-strokes from 11" up to 40" on 3-axis machines and 16" up to 40" on 5-axis, standard 18 HP spindles with 24 HP or 33 HP options, a standard 12-pocket rotary automatic tool changer, and 2 or 4 vacuum zones. Twin-table machines support pendulum processing — loading one table while the other cuts. Model numbers such as 98C, 122C and 146C denote table configurations.
What to check when buying used- Controls: confirm the FANUC control generation, that parameters and backups are present, and that the Onsrud HMI/SeeNC interface is intact and licensed. - Spindle and hours: ask for spindle hours, run hours, any rebuild history, and check for drawbar condition, taper wear and spindle noise at speed. - Structure and motion: inspect the thick steel base, bridge and columns for cracks or repairs after crashes; check linear guides, racks and pinions, ballscrews and lubrication systems. - Tables and vacuum: verify vacuum zone plumbing, table flatness, spoilboard condition and that zone valves seal properly. - Tool changer: cycle the ATC through a full sequence, and check pockets for damage and alignment. - Options: dust hoods, second spindles, second tool changers and rotary axes are common options — confirm what is actually fitted, since they affect value and usability.
Service and partsOnsrud builds, supports and trains from its Troutman, North Carolina facility, and the company notes it still runs its own machines on its shop floor after 25-plus years. For a used machine, parts availability, retrofit and rebuild support, and factory training should be confirmed with the manufacturer or a regional dealer before purchase.

Frequently Asked Questions
Where are C.R. Onsrud CNC routers made?
They are built at the company's factory in Troutman, North Carolina, in the United States. Onsrud states that over 80% of its manufacturing is done in-house, including frames, sheet metal, precision components, paint and assembly.
What materials can a used Onsrud router cut?
Onsrud describes its router platforms as processing solid wood, advanced polymer plastics, composites and nonferrous metals. The heavier C-Series is specifically positioned for dense materials, with a rigid steel base and high-torque spindles suited to deep cuts and high feed rates.
What controls do Onsrud CNC machines use?
The C-Series is published as using FANUC controls, combined with Onsrud's own touchscreen HMI and SeeNC interface. When buying used, confirm the FANUC control generation and that backups, parameters and the Onsrud interface are all present.
What does the model number like 98C or 122C mean on an Onsrud C-Series?
The C-Series model designations relate to table size and configuration — for example, 98C, 122C and 146C are listed with different X and Y table dimensions and different numbers of vacuum zones. Always confirm the actual table size, axis count and spindle configuration on the specific machine.
What should I check on a used Onsrud twin-table router?
Check vacuum zone plumbing and sealing, table flatness and condition, and that the pendulum processing sequence works with both tables. Also cycle the automatic tool changer, check spindle hours and rebuild history, and inspect the base, bridge and guides for crash damage.
Can I still get parts and service for an older Onsrud machine?
Onsrud supports, services and trains from its Troutman, North Carolina facility, and says it still operates its own machines daily after more than 25 years. For any used machine, confirm parts availability and service coverage with the manufacturer or an authorized regional dealer before buying.
