Many industrial machines are the stuff engineers dream of. They are highly technical, precision instruments, despite their bulk and size. If your company is looking to purchase some newer (but gently used) machines, such as nanopositioners, you should not buy them sight unseen. You can trust the manufacturer to send you a sight-unseen machine and know that it works, but when you see nanopositioners for sale by another private company/competitor, you need to check them out first. Here are three things you should do before buying any used nanopositioners.
1. Ask to See It in Action
Tell the seller you want a demo. A nanopositioner should operate in such a way that its precision instruments are fully responsive to the controls and the precision instrument operates perfectly and flawlessly on three axes. Vibrations throughout the factory as well as through the factory floor should not affect the nanopositioner's operation in any way.
2. Ask About Recent Repairs
Slightly used nanopositioners should not have a repair list several miles long. In fact, most models should have no repairs within the first ten years of use. This is also a good time to ask about the age of the machine and why the seller is letting it go. Any answer other than the fact that the company wants to upgrade to the latest model that is due to arrive on the market in less than a month may indicate that the machine has a problem that you just cannot see right now.
3. Tell the Seller You Are Interested, but Thinking It Over
Regardless of what you buy, you always tell a seller that you will wait on it, especially when it is used technology like a nanopositioner. It is a perfectly acceptable answer for now, and it will give you time to look up any pertinent information on the make and model of nanopositioner for sale. You may find that the nanopositioners that the seller is trying to unload experienced some operational flaws and that the majority of them were recalled. Maybe the readouts say that the products created were perfect, when a closer inspection reveals that the nanopositioner made errors (which it definitely should not be doing). Better yet, ask the seller in advance for the year, make, and model of the nanopositioner so that you can do your research in advance and have an answer for him/her the day of the demo.Share
