Used CMM Buying Guide: Avoid the Used CMM Traps

Buying a used CMM can be one of the smartest ways to add measurement capacity fast, without paying new-machine pricing or waiting on long lead times.

It can also turn into a money pit.

The most common mistake is buying a used CMM “as is” because it looks like a deal on paper. Then the unpleasant surprises show up after the machine arrives: installation problems, software issues, missing components, and repair costs that were never part of the original budget.

This guide breaks down where used CMM purchases go wrong, and how to buy a system that is actually ready to run.

The reality of “as-is” used CMMs

A lot of used CMMs are sold as-is for one reason: the seller is offloading risk.

Common as-is surprises include:

  • The CMM moves, but it will not repeat reliably across the volume
  • The controller is outdated or unsupported
  • The software license is not transferable, or requires expensive rework
  • Probing is incomplete (missing stylus kits, qualification spheres, probe head components)
  • Installation support is not included, or the move damages accuracy
  • Calibration and verification are outdated, missing, or done in conditions that do not match your environment

If you do not plan for these items up front, you end up buying a “cheap machine” and paying new-machine money to make it usable.

Three areas where buyers get burned most

1) Installation and relocation

A used CMM that measured fine in one building can measure poorly after relocation if the move is not handled correctly.

What gets missed:

  • Proper rigging and leveling
  • Air quality and air prep requirements
  • Power requirements and grounding
  • Environmental effects (temperature swings, vibration, shop floor conditions)
  • Post-install verification to confirm performance

If installation is treated like an afterthought, accuracy becomes a gamble.

2) Software and licensing

Software is one of the biggest sources of surprise cost.

What gets missed:

  • License type (dongle, node-locked, floating)
  • Transferability and paperwork
  • Version compatibility with the controller and PC
  • Required modules for GD&T, scanning, reporting, or offline programming
  • Maintenance status and update costs

A used CMM without verified software and licensing is not a complete system.

3) Repairs, parts, and probing

Mechanical wear, electronics, and probing systems can look “fine” until you start using the machine.

What gets missed:

  • Air bearing condition and leaks
  • Scale condition and availability
  • Controller parts support and lead times
  • Probe head condition and repeatability
  • Missing accessories that are required for daily use

This is why two used machines with the same model name can have completely different real-world value.

What “turnkey” should mean when buying used

A used CMM should not be judged by what it is, but by what it can do on day 1.

A turnkey used CMM should include:

  • Confirmed mechanical health and smooth axis motion
  • Supported controller electronics
  • Verified software installation and license transfer
  • Complete probing package required for your parts
  • Proper installation and leveling
  • Post-install verification so you know it holds spec

If any of that is unclear, the machine is not turnkey.

How Made to Measure removes the risk

Made to Measure takes a different approach than the typical as-is used equipment sale.

Instead of selling a machine and letting you figure out the rest, Made to Measure has a dedicated CMM service team that brings machines back to life and delivers a system that is ready to run.

What that looks like:

  • Reconditioning and inspection focused on real performance, not cosmetics
  • Modernizing systems with Renishaw technology where it makes sense
  • Solving the common blockers up front: installation, probing, and software readiness
  • Delivering a turnkey system so you can run parts on day 1, not “someday after repairs”

The goal is simple: you should not have to gamble on whether your used CMM will be usable after it is installed.

A practical checklist before you buy any used CMM

Before you commit, demand clear answers on these points:

  • Who installs it, levels it, and verifies it after the move
  • What software is included, what version, and whether the license transfers
  • What probing is included and whether it matches your parts and tolerances
  • What verification data exists, and whether it reflects real conditions
  • What parts and service support exist for the controller and probe system

If a seller cannot answer these cleanly, you are buying uncertainty.

Bottom line

Used CMMs can be a great investment. As-is used CMMs are often a hidden project.

If you want a system that runs on day 1, buy from a team that can prove performance, support installation, and deliver a complete solution with modern probing and service backing.

If you want help evaluating a used CMM before you buy, Made to Measure can review the machine, the configuration, and the installation plan so you know exactly what you are getting.
