There are many different ways to purchase used manufacturing equipment, including CMMs. Before you start this journey, there are some fundamental questions that you should answer before you consider the purchase of any CMM, whether new or used, because a machine that doesn’t meet your measurement needs is no bargain, no matter what the price. This quick checklist is a simple needs analysis you can complete before you start your search: What size of machine do you need? Determine this by thinking about the largest part you need to measure and adding clearance area for probing. What are your accuracy requirements? Study prints that contain the tightest tolerances for size, true position and form. Based on the complexity and variation of parts, what type of probe head is required? Fixed, rotating, touch trigger or scanning. What are your individual preferences? Likes and dislikes about current or past systems Or software you have worked with. This list is over-simplifi ed, but ensuring you’ve done some basic homework before you buy will help narrow down your search to machines that will best meet your needs. COMMON RISKS WHEN BUYING A USED CMM When buying a CMM from an open-market source such as eBay, bankruptcy auctions, a broker or a third party service provider, there are many potential risks. Here are top fi ve most common. 1. Unknown Damage to the Machine – With limited time or no ability to have someone knowledgeable to inspect the equipment, you run the risk there is signifi cant hidden damage. Repairs can be expensive. 2. Other Costly Upgrades – Software, fi rmware, air hose or electronic upgrades could be required. 3. Legal Software – Most software is licensed, not sold. If the software with the machine is “used” there is a high probability that it won’t be legal unless the license is officially transferred to you. The software is also often out-of date and might not be supported. 4. Hidden Costs – Packing, transportation, installation, calibration are often not part of the selling price. To get the machine usable, significant expense and additional hassle is required. 5. Uncertain Market Value – There is no “blue book” for CMMs making it dangerous for the uninformed buyer. Often the seller isn’t likely to know how to fairly price the machine or even know if the machine is a good candidate to own as a used CMM. Used CMMs are not good candidates for purchase if parts & service are unavailable and if software cannot be upgraded. Finally, there is always a danger in buying something used from someone that can’t back the purchase. A “great deal” often isn’t so great when all the extra costs to get the machine running properly are added in.
