Traditional CMMs – Why They’re Still Relevant

Traditional CMMs – Why They’re Still Relevant

In a world full of optical machines and 3D scanning arms, traditional coordinate measuring machines (CMM) are still relevant.

Below we highlight just three of the reasons why your traditional CMM can be useful for many years to come.



The need to measure holes, planes and spheres still exists. The accuracy of the traditional CMMs is well above that of the 3D scanning equivalent. 

As precision measurement becomes more and more relevant in the quality world and with more investments being made, the traditional CMMs high accuracy is king.



Each coordinate measuring machine produced at Eley is accredited to ISO 20360-2. This is the only way to validate your measurement results.

Traceability of artefacts allows users to verify their measurement with confidence. Many manufacturers and quality departments rely heavily on traceability.



The introduction of scanning technology is still a fairly new one in the world of precision measurement. This means that occasionally there are still some bugs to iron out.

The traditional coordinate measuring machine has been around since their introduction in the 1950’s. Those currently residing on the shop floor might have been there for ten years with no problems at all.

If you feel your CMM is getting “out of date”, there are options available for software and hardware updates which keep the machine ‘in the now’.


To wrap up; a traditional Coordinate Measuring Machine can have the lifespan of a human, the accuracy is still unbeatable and you can be 100% confident in your measurements.
