What does CNC machine repair cost?

Real-world price ranges for the repairs machine shops call about most: service calls, spindles, ballscrews, drives, alignment and more. Use it to budget, sanity-check a quote, and decide between repair and replace.

These are rough U.S. ranges, gathered from people who run maintenance and do this work. Hourly rates run from about $150 to $450, and most shops pay around $275. Ranges are not quotes. Your price depends on the machine, the parts, how far the tech travels and how fast you need it. Factory (OEM) service often runs higher.

Service calls and labor

Job	Typical range	What moves the price
Field service labor	$150–$450 per hourMost shops pay around $275	Rate depends on the tech’s skill, the machine and how fast you need them. Controls, 5-axis and factory (OEM) techs sit at the top of the range.
Trip or travel charge	$0–$300, or travel time billed hourly	Many companies bill portal to portal. A local tech who already covers your city saves you the most here.
After hours, weekends, holidays	1.5x–2x the normal rate	Ask before you call. Some contracts include emergency response.
Diagnostic visit (half day)	$600–$1,800	Often credited toward the repair if you go ahead.

Spindles

Job	Typical range	What moves the price
Spindle rebuild, belt-driven 40-taper	$3,500–$9,000	Bearing type, damage to the shaft and housing, and turnaround time (rush adds 25–50%).
Spindle rebuild, high-speed or motorized	$8,000–$25,000+	Built-in motors, 15,000+ RPM and HSK spindles cost more. Exchange units cut downtime.
New OEM replacement spindle	$12,000–$45,000+	Compare to a rebuild with warranty before you buy new.
Spindle remove and reinstall labor	$2,200–$6,000	Usually 1 to 2 days on site, including runout and drawbar checks.

Axes, ballscrews and ways

Job	Typical range	What moves the price
Ballscrew repair (regrind and reball)	$1,500–$5,000 per screw	Length, lead accuracy class and how worn it is.
New ballscrew	$2,000–$8,000 + install	Install with alignment is usually 1 to 2 days.
Support bearing replacement	$800–$2,500	Often done with a ballscrew job to save labor.
Way wiper and way cover repair	$500–$3,500	Cheap insurance. Torn wipers let chips into ballscrews and ways.

Controls, drives and motors

Job	Typical range	What moves the price
Servo or spindle drive repair (Fanuc, Siemens, etc.)	$900–$3,500	Exchange units ship faster but cost more up front.
Servo motor repair	$700–$2,500	Includes bearings, seals and testing. Encoders cost extra.
Encoder (pulse coder) replacement	$800–$2,500 + labor	Absolute encoders need the axis reference set afterward.
Control board or power supply repair	$600–$3,000	Obsolete boards cost more and take longer. Keep a parameter backup.
Full CNC control retrofit	$30,000–$90,000+	Worth it on a solid machine with an obsolete control. Compare to a used machine.

Accuracy, maintenance and moves

Job	Typical range	What moves the price
Ballbar test	$600–$1,500 per machine	Fast way to see backlash, squareness and servo mismatch.
Laser alignment and calibration	$1,800–$4,500 per machine	Machine size and number of axes. Often paired with leveling.
Preventive maintenance visit	$550–$1,500 per machine	PM contracts for several machines usually lower the per-machine price.
Crash repair	$2,500–$30,000+	Ranges from a realignment to a spindle, ballscrew and casting repair.
Machine move and re-install (local)	$3,000–$15,000+	Rigging, leveling, power hookup and accuracy check.

How to keep the bill down

Call with details. Make, model, control, the exact alarm number and a short video. A tech who knows what to bring can often fix it in one trip.
Use a tech who already covers your city. Travel time adds up fast. Find one near you.
Ask for the rate and trip charge up front. Verified companies on this site agree to tell you before the visit. See our standards.
Ask about rebuild or exchange. A rebuilt spindle or exchange drive is often half the cost of new.
Do the PM. Most expensive repairs start with a cheap problem: dry ways, a torn wiper, coolant in a motor. Get our free PM checklists.

Repair or replace?

A simple rule many shop owners use: if the repair costs more than half of what a comparable used machine would cost, and the machine has other problems coming, get a quote on replacing it. If the castings, ways and control are good, repair almost always wins. Read our full guide on repair or replace.
