On any factory floor, the best way to maximize efficiency is through quality control, which is why many production lines incorporate a coordinate measuring machine (CMM) to provide regular checks on products and parts being produced. These machines offer incalculable savings by reducing waste and ensuring that defective parts don’t hamper productivity. Not every production line needs the very latest in CMM technology, though, and with so many excellent used CMM on the market, it can be much more economical to invest in a high quality used machine rather than paying full price for the newest equipment.
How to select CMM?
CMMs are sophisticated and sensitive pieces of machinery, however, and if a CMM is not operating at peak condition, it can compromise your entire production line. So what should you look for in a used CMM, and how can you find out which providers are reliable?
It isn’t hard to find used CMM machines for sale, especially if you are looking for a common type, like a cantilever or bridge CMM designed for measuring small to medium-sized components. A quick Google search is likely to turn up several potential sellers offering reasonable prices for recognizable brand names. But while these offers may seem like simple, hassle-free ways of purchasing equipment, they may create more headaches in the long run.
It is always best to buy from professional CMM dealers who have tested their second-hand machines extensively before putting them on the market. When considering CMM dealers, ask whether they have done a thorough check on all probes, drive systems, and cabling beforehand, and ask what kind of support they provide in terms of training and repairs should an issue arise. You should also try to find a provider that is up-to-date with the latest CMM software, and who can advise you regarding which programs are best suited to helping you get the most out of your machine. Not every CMM needs the most recent software, but knowing what is standard for the particular machine you are using will help you make an informed decision.
It is also important to make sure any potential used CMM dealer offers help with installation. In order to function properly, a CMM machine needs to be properly calibrated to the particular space in which it is operating. Small things, like changes in temperature, can have a significant impact on the functionality of CMMs, which is why having a CMM professionally installed is the best way to guarantee it will operate at peak efficiency from day one.

By making sure that parts and products being produced are accurate and free of defects, CMMs play a vital role in the ensuring the smooth operation of any production line. For manufacturers who want to save costs on equipment without compromising the quality of their goods, buying pre-owned CMMs from established retailers is one of the best ways to find the right equipment for the job at an affordable price point.
