Things To Consider Before Buying a Used CMM

A coordinate measuring machine (CMM) is an advanced piece of equipment that measures the dimensions of particular objects.

Their capability for high precision makes them highly beneficial for machine parts manufacturers, especially for clients that demand accuracy and consistency. Industries that may require a CMM’s capabilities include aerospace, automotive, heavy machinery, defence, electronics, and medicine.

A CMM could significantly improve many manufacturing companies’ productivity, efficiency, and accuracy. However, buying one is a significant investment, especially when the CMM is brand-new.

Buying a used CMM is a good alternative for companies that want to save on acquisition costs. However, there are some factors that one should consider in how to choose a used CMM.

Cost

Before buying a used CMM from the first vendor you come across, do your research. Used CMMs often come at a lower cost than their brand-new counterparts, but they are still significant investments.

Compare prices between new and used CMMs and decide whether the price difference is substantial enough to justify buying a new or used CMM. Older or smaller models are often more affordable than newer and bigger machines.

Seller’s Guarantee

Warranties are highly beneficial and often essential when making such an investment as a CMM. However, buying used CMMs usually means forgoing the warranty that comes with brand-new machines.

Before buying a used CMM, ask your vendor about their guarantee. Make sure to assess whether the machine still functions as intended or has any issues you need to consider or repair before use.

Ideally, you should only buy used machines that have been repaired or serviced beforehand. This helps guarantee a smoother experience once you integrate the CMM into your daily operations. 

Software

Another factor to consider in a used CMM is its software. Ask your vendor whether the machines are compatible with more recent or upgradable software.

You can also ask the CMM vendor to upgrade the machine software for you. It would save you the trouble of finding new and compatible software for your intended functionality. 

Using newer software also helps in future-proofing your used machine, making it last longer.

Maintenance

As with any piece of equipment, it’s vital to conduct a thorough inspection of the functionality of your used CMM. Ideally, it should have no significant issues and require little to no further maintenance.

If your used CMM still requires maintenance, factor these costs into your overall purchase. Minor, occasional repair or maintenance expenses might not seem like much, but recurring problems could add up.

Replacement Parts

Eventual CMM repairs are inevitable. One day, you might need to replace your probes or any other part that wears out or breaks down. 

For this reason, make sure replacement parts are readily available for your used CMM. Obsolete, obscure spare parts will cause delays and impact your production process. 

Customer Service

Your CMM purchase is only one part of the customer experience. Your vendor should know this and offer further assistance when necessary.

Ideally, you should be able to approach your used CMM vendor for assistance regarding repairs, maintenance, training, and troubleshooting. This helps their business and offers you a consistent helpline should any problems arise.

Buying a used CMM is an excellent alternative to purchasing brand-new equipment. Many used machines still perform well and would be a helpful addition to your manufacturing and quality control processes. If you plan to purchase a used machine, scrutinize your choices to ensure quality and longevity.
