Coordinate Measuring Machine Parts

CMM Products: Replacement Parts, Probes & Extension Kits

What Are CMM Products?

A coordinate measuring machine (CMM) captures precise dimensional data from manufactured parts for inspection, tolerance validation, and reverse engineering. CMM stands for coordinate measuring machine, and it can be used in a wide variety of applications across many different industries, such as aerospace, automotive, medical, and energy, for accurate measurement. Coordinate measuring machines catch dimensional errors before defective parts move to the next production stage for quality assurance, measurement accuracy, and error reduction, and the right parts selection supports consistent CMM calibration performance. Metrology Parts is pleased to offer quality CMM replacement parts, extension kits, and more to keep your CMMs running at peak performance, along with complete coordinate measuring machines and related CMM equipment. Our offerings cater to various CMM solutions, including mechanical probes, laser probes, and other types of CMM parts.

How CMMs Work in Inspection and Reverse Engineering

CMMs measure the distance between two coordinates on a 3D object. They can use different types of sensors or probes to accomplish a CMM inspection, including mechanical, laser, optical, and white light (including compatible video measuring machine parts). Operators can control the probes by computer or manually, depending on the CMM configuration.

CMM technology can be used for many applications, including inspection and quality control, reverse engineering, or even to get the most precise measurement of parts you need to manufacture, so that there is less excess scrap material produced by your operations, with the right workpiece fixturing helping you hold parts stable for repeatable results.

Industries That Use CMM Products

When you have all the right parts, using CMMs to study and measure products made by other companies in your industry can help you go far to gain a competitive edge. Some of the many industries that use and benefit from CMMs and their high-precision measurements include:

  • aerospace: validate tight-tolerance airframe and engine component geometry
  • automotive: verify part-to-CAD dimensions for in-process and final inspection
  • aviation: inspect flight-critical components for dimensional compliance
  • energy and power: measure turbine, rotor, and valve features for fit and performance
  • forensics: document and compare dimensional evidence with repeatable measurement
  • heavy machinery: confirm large-part alignment, bores, and mating surfaces
  • medical: check implant and instrument dimensions against regulatory tolerances
  • high tech: measure precision housings and connectors for assembly accuracy
  • fashion and jewelry design: capture complex shapes for replication and quality checks

CMM Parts We Carry: Brands, Probes, and Accessories

The high-quality CMM parts that you can order online from Metrology Parts include touch probes, probe heads, CMM stylus and styli, extension kits, and DCC servo boards. We carry trusted brands such as Renishaw, Mitutoyo, Brown & Sharpe CMM parts, Hexagon Metrology parts, and OGP Optical Gaging Products, with many options available through our CMM and VMM probing systems selection.

Touch probes trigger measurement points on contact to capture discrete coordinate data for inspection routines. Probe heads position and articulate the probe so you can access features at different angles without reorienting the part. Styli (including a cmm stylus) connect the probe to the contact tip and let you match length and tip geometry to the feature you’re measuring. Extension kits help the probe reach deep bores, recessed features, and other difficult geometries without replacing the machine, and they’re a practical upgrade path when you’re considering a CMM retrofit kit approach for existing CMMs. DCC servo boards control automated axis movement and are critical to restoring machine motion on direct computer-controlled CMMs.

New, Rebuilt, and Exchange CMM Parts: Which Option Is Right for You?

Option Best Use Case Cost Profile Warranty or Support Notes
New critical components where you want the latest revision and longest service life highest upfront cost typically offers the most comprehensive manufacturer or supplier support
Rebuilt restoring performance on legacy systems when new parts are limited or unnecessary mid-range cost often includes tested functionality and defined rebuild standards
Exchange minimizing downtime by swapping a failed component with a ready-to-ship equivalent often lower cost than new support terms vary by component and exchange program requirements

Why Buy CMM Parts Online from Metrology Parts?

Buying parts online allows you to do your own CMM repair to your CMMs, saving you time and money. Not only can you avoid excess downtime with our one-day shipping on replacement parts, but you can expand the capabilities of your CMMs with our extension kits and CMM retrofit kit upgrade paths.

Frequently Asked Questions

What CMM replacement parts does Metrology Parts carry?

We carry common CMM replacement parts such as touch probes, probe heads, styli, extension kits, and DCC servo boards, with options across multiple major metrology brands.

How do I know which CMM probe is compatible with my machine?

Match the probe and interface to your CMM’s probe head, mounting system, and controller requirements. If you’re unsure, use your CMM model information and current probe part numbers to confirm fit before ordering.

What is the difference between a new and a rebuilt CMM part?

A new part is factory-new, while a rebuilt part has been restored to working condition through a defined rebuild process and functional testing. The right choice depends on your uptime needs, budget, and support requirements.

How fast can I get CMM replacement parts?

Many replacement parts ship quickly, and our one-day shipping option helps reduce downtime when you need to get a CMM back into service.

Can I use CMM extension kits to expand my machine's measurement range?

Yes. Extension kits can extend reach to deep bores, recessed features, and other hard-to-access geometries, which can expand practical measurement access without replacing your CMM.
