Revitalizing your CMM: A Guide to Retrofitting and Upgrading

In the manufacturing industry, precision and accuracy are crucial components in ensuring the quality of the products produced. This is where coordinate measuring machines (CMMs) come in, allowing manufacturers to measure and inspect finished products and components with unparalleled accuracy. However, as technology advances and the demands of the industry continue to evolve, it becomes necessary to upgrade or retrofit existing CMMs to keep up with the latest advancements.

If you own a CMM that has been serving you well for years, it might be time to consider retrofitting or upgrading it. In this article, we will explore what these processes entail and why they are important.

What is CMM Retrofitting?

CMM retrofitting is the process of modernizing an existing coordinate measuring machine to improve its accuracy, efficiency, speed, and overall performance. This is typically done by replacing outdated or worn-out components with new and advanced ones. Retrofitting a CMM can give it a new lease on life and extend its service life significantly.

Why Retrofit Your CMM?

Upgrading your CMM through retrofitting has many benefits, including:

Improved accuracy: Old CMMs can lose accuracy over time due to wear and tear of components. By retrofitting and upgrading, you can get precise measurements again.

Improved speed: With outdated technology, a CMM could take longer to scan and measure. Upgrading to modern technology can speed up the process.

Cost savings: Retrofitting can be a cost-effective alternative to purchasing a new CMM.

Increased efficiency: A retrofit can add new capabilities to your CMM that can improve efficiency and reduce overall production time.

Upgrading your CMM

Another option to improve your CMM’s functionality is to upgrade it. Upgrading typically involves replacing a component or a group of components with a newer version that is more advanced and improved.

Why Upgrade Your CMM?

Some benefits of upgrading a CMM include:

Higher resolution: Upgrading to a higher-resolution machine will give you the ability to measure smaller tolerances.

Increased measurement range: Upgrading to a machine with a higher measurement range can help save time and improve accuracy.

Improved scanning capability: Upgrading can give your CMM the ability to measure complex geometry, such as sheet metal forming.

Enhanced software: Software upgrades can improve the functionality and ease of use of your CMM.

When should you upgrade your CMM?

Upgrading your CMM is a good idea when you want to increase productivity, improve accuracy, or when the machine is outdated and can no longer provide the necessary functions.

Which is better, retrofitting or upgrading?

The answer to this question depends on the condition of the CMM and what you want to achieve. Upgrading is better when the problem is with one or more components, and the machine is still in good condition overall. Retrofitting is better when the CMM is outdated, and its overall condition is in decline.

What to consider when retrofitting or upgrading your CMM

When considering retrofitting or upgrading your CMM, there are several factors to consider:

Budget: Retrofitting is often less expensive than buying a new CMM. Upgrades, on the other hand, usually range from inexpensive to expensive depending on the components you want to replace.

Machine condition: If your CMM is in good condition overall, upgrading might be a better option. If the CMM is in decline, retrofitting may be more cost-effective.

Accuracy requirements: If your measurements require high accuracy, upgrading to a higher resolution machine is a good idea.

Data management: If you have specific data management needs, look for upgrades or retrofits that incorporate software that meets your needs.


Retrofitting or upgrading your CMM is an important process that can help you achieve higher accuracy, faster measurement, and improved efficiency. By considering your budget, machine condition, accuracy requirements, and data management needs, you can make an informed decision on whether to upgrade or retrofit your CMM. Regardless of which process you choose, it is important to choose a reputable dealer or manufacturer that can provide all of the services you need. With a revitalized CMM, you can enhance your manufacturing process and achieve higher-quality products.
