How to choose a CNC repair company: 10 questions to ask

The middle of a breakdown is the worst time to pick a repair company. Do it now, while your machines are running, and save the number. Here are the questions we ask.

The 10 questions

  1. Do you work on my exact machine and control? “We fix everything” is a red flag. Ask about your brand, model and control by name.
  2. Who will actually come out? Ask how many years of CNC experience the tech has, and whether they’re an employee or a subcontractor.
  3. How fast can you get here when a machine is down? Get a real answer for your city, not a slogan.
  4. What’s your hourly rate, and is there a trip charge? Also ask about overtime, weekend rates and minimum hours.
  5. Do you stock common parts, or have to order everything?
  6. Can you rebuild spindles, drives and ballscrews, or do you send them out? In-house rebuild shops are often faster.
  7. Do you offer exchange or loaner parts? An exchange spindle or drive can get you running while yours is rebuilt.
  8. Are you insured? Ask for a certificate of insurance. They’ll be working in your plant.
  9. Can I talk to two shops you’ve worked for?
  10. Do you offer preventive maintenance plans? A company that sells PM is betting on keeping your machines running, not just fixing them.

Warning signs

  • They won’t give a rate until they’re on site.
  • The phone is answered by a call center that “will have someone call you back.”
  • They want to replace boards and parts before diagnosing.
  • No address, no insurance, no references.

Dealer or independent?

Dealers know their own brand deeply and handle warranty work. Independent repair companies often respond faster, work across many brands, and cost less. Many shops use both: the dealer for warranty and new machines, an independent for everything else.
