Coordinate measuring machines are a cost-effective investment as they accurately and precisely measure the geometry of objects to streamline production processes. When you buy your CMM used, however, you can save even more at little risk or sacrifice.

There is a common misconception that used means old. However, the reality is that buying used is the best way to get value for your money while also ensuring production value.

Buy cautiously. When you pick the right retailer, ask the right questions, and make the right upgrades, you will be equipped with a CMM that works like new.

These are the main things you will want to look for in your used CMM to ensure it will reach its full capabilities once put into action.

Make Sure it Has Updated Software

When you buy a used CMM, you want to make sure its software isn’t outdated or worse for wear. After all, why buy used CMM equipment if it is not up to modern standards? The good news is that, because CMM manufacturers are continually improving and updating their software, many retailers will update the software of machines before they hit the shop floor.

If there is specific software you are seeking, you can always make a special request, or have it installed after your purchase. Bonus points will go to retailers who can provide training alongside any software updates to ensure that all machine users are comfortable with operating the machinery and interpreting the data it collects.

Find Video Footage of the Product

Some retailers will post the name and specs of a used CMM, but others will provide 360 videos that display the used machine in operation. This is the best way – other than seeing the equipment in person – to gauge the machine's functionality and quality.

Make Sure the Retailer is Authorized

Buy from a certified and verified trusted retailer to ensure that your machine is up to par. Specifically, buy your used CMM from a dealer that is authorized by the Machinery Dealers National Association.

When you buy from an MDNA authorized retailer, you get a guarantee to protect you from being left with an unsatisfactory machine. Review a retailer's refund process to ensure you are buying from an authorized retailer that can provide you with a warranty for your peace of mind.

Make Sure It’s Adequately Refurbished

For a used machine to work like new, it needs to be updated and refurbished. Reputable retailers will refurbish and retrofit CMMs to restore them to their former glory and ensure they are equipped with the necessary updates to work like their modern counterparts.

Ensure Testing

According to Metrology News, there are an estimated 150,000 coordinate measuring machines installed globally. CMM retailers will often test machinery before putting it on the shop floor and selling it.

You will know that your machine will work like new because your retailer should have already tested it against other devices to ensure it is up to standards.

Review Packaging & Shipping Practices

The last step of purchasing a used CMM is getting it sent to you to install it for use. That said, you want to familiarize yourself with the retailer's shipping processes before making a purchase. By the time the machine gets to you, you want it to be still working like new.

These metrology machines have sensitive parts that can be damaged when transported. An experienced CMM service company will have all the necessary materials (skids, trailers, crates, etc.) to thoroughly and safely package and transport your product.
