Onsrud models across the full product line, from the compact M-Series 3-axis routers through T-Series, G-Series, E-Series, Wide Pro, and HR-Series High Rail machines, plus X-Series and EX-Series profile machining centers.

The Onsrud family manufacturing legacy spans five generations, beginning in 1915 when Oscar Onsrud and his son Rudolph invented and patented the first air-powered high-speed spindle. Charles "Charlie" Rudolph Onsrud founded C.R. Onsrud, Inc. in 1976 in North Carolina, initially building his patented Inverted Router. In 1992, Charlie's son Tom and brother Bill engineered the company's first CNC machine, and by 1996, C.R. Onsrud sold its first CNC router (a C-Series that is still running today). All machines are designed, fabricated, machined, stress-relieved, painted, assembled, and shipped from the company's 250,000-square-foot campus in Troutman, North Carolina. C.R. Onsrud offers nearly 50 standard models of 3, 4, and 5-axis CNC routers, mills, and machining centers, with 50% of production built to order. The company serves customers ranging from small job shops through global manufacturers in aerospace, automotive, furniture, composites, marine, transportation, and building industries.

C.R. Onsrud 3-Axis & 5-Axis CNC Routers

The M-Series provides compact, economical 3-axis moving gantry routing for wood, plastic, foam, aluminum, and nonferrous materials. The T-Series and G-Series step up to larger table sizes (up to 429 by 61 inches on the G-Series) for production-scale panel processing and large-format machining. The E-Series delivers extreme-performance routing for composites, fiberglass, and nonferrous metals. 5-axis spindle capability is available across most series for complex contour milling, trimming, and multi-sided machining on both open and enclosed platforms. All machines support an optional 4th axis.

C.R. Onsrud High Rail, Profile & Specialty Machines

The HR-Series High Rail machines offer over 1,000 square feet of work envelope with up to 10 feet of Z-stroke for processing bulky, large, and uniquely shaped components. The X-Series and EX-Series profile machining centers handle drilling, tapping, milling, and sawing of structural profiles and extrusions. Multi-spindle configurations (twin and quad) are available for simultaneous or independent operation. The Inverted Router, patented in 1976 and still manufactured, serves secondary routing operations with the cutter entering from underneath the workpiece for improved safety and visibility.

What to Look for When Buying a Used C.R. Onsrud

C.R. Onsrud CNC routers are built with welded steel frames that are stress-relieved before final machining, Fanuc controls, and high-speed spindles designed for continuous production duty. American-made construction and modular design make these machines durable and serviceable. Here is what to inspect on used units.

Test the spindle condition and performance. C.R. Onsrud machines use high-speed spindles rated for continuous operation. Measure spindle runout at the collet or toolholder with a test indicator. Listen for bearing noise at operating RPM. On 5-axis machines, test all rotary axes for smooth motion and positional accuracy. Check spindle hours on the control if available, as high-speed router spindles have defined service intervals.

Inspect the gantry, rails, and drive system. On moving gantry models (M, T, G, E series), verify smooth travel across full X-axis range. Check linear rails and bearings for play or roughness. Inspect rack-and-pinion or ballscrew drives for backlash and wear. On High Rail machines, pay particular attention to Z-axis travel and verify consistent accuracy across the full stroke.

Evaluate the table and vacuum system. Most Onsrud routers use vacuum hold-down tables for workpiece clamping. Verify that the vacuum pump produces rated pressure and that table seals and zones are intact. Check the spoilboard for excessive wear or unevenness. On twin-table or shuttle-table configurations, test the table exchange mechanism for smooth operation.

Verify the Fanuc control and software. Confirm clean power-up, successful axis homing, and correct program execution. Test all I/O functions including spindle start/stop, vacuum control, tool change, and dust collection interlocks. On machines with automation, verify communication between the control and material handling systems.

C.R. Onsrud M-Series (Compact 3-Axis)

The M-Series is C.R. Onsrud's compact 3-axis moving gantry CNC router with a table size starting at 97 by 49 inches. Designed for wood, plastic, foam, aluminum, and nonferrous materials, the M-Series provides industrial-grade performance in a smaller footprint. It serves shops entering CNC routing, educational programs, and production environments with moderate table size requirements. The M-Series supports an optional 4th axis and is the most commonly traded Onsrud model on the used market.

C.R. Onsrud T-Series, G-Series & E-Series

The T-Series provides mid-range moving gantry capability with larger table sizes than the M-Series. The G-Series is C.R. Onsrud's large-format moving gantry platform with table sizes up to 429 by 61 inches, serving production panel processing and large-part machining. The E-Series delivers extreme performance for demanding materials including composites, fiberglass, and nonferrous metals. All three series are available with 5-axis spindle configurations for complex contour milling and trimming.

C.R. Onsrud HR-Series High Rail

The HR-Series High Rail machines provide over 1,000 square feet of work envelope with up to 10 feet of Z-stroke, processing bulky and uniquely shaped components that exceed the capacity of standard gantry routers. High Rail machines serve aerospace, marine, transportation, and mass timber construction applications.

C.R. Onsrud Profile Centers & Inverted Routers

The X-Series and EX-Series profile machining centers handle drilling, tapping, milling, and sawing of structural aluminum profiles, extrusions, and similar components. Multi-spindle configurations enable simultaneous or independent processing on separate tables. The Inverted Router (models 500 VS, 750 SS, 900 VS/VSX) places the cutter below the table with the pattern on top for improved safety and visibility. Patented in 1976, it is still manufactured and remains a staple in woodworking and pattern-making shops.

Onsrud CNC routers handle wood, plywood, MDF, plastics, acrylic, PVC, foam, composites, fiberglass, carbon fiber, aluminum, and other nonferrous metals. M-Series for general routing, E-Series for composites and nonferrous, HR-Series for oversized components.

What should I inspect before buying a used C.R. Onsrud?

Test spindle runout and bearing condition, inspect gantry rails and drive system for wear, verify vacuum table pressure and zone integrity, check spoilboard flatness, and confirm Fanuc control operation. On 5-axis models, test all rotary axes for accuracy.

What is the Onsrud family history?

The Onsrud manufacturing legacy spans five generations. Oscar Onsrud and his son Rudolph invented the first air-powered high-speed spindle in 1915. Charles Onsrud founded C.R. Onsrud, Inc. in 1976, building patented Inverted Routers. His son Tom led the transition to CNC machinery in the 1990s.
