I am involved in assessing equipment for a vehicle refurbishment workshop like lathe ,milling machine, crankshaft re grinder and so on.How old should these machines be to be considered obsolete(years)?Thanks
Something is only obsolete when you no longer have a use for it. As long as everything is in safe, working order and performs a useful function, it is not obselete. For woodworking, I still use large wooden clamps with wooden screws. They've gotta be like 30 years old, but they do exactly what I need them to do. If I got a strong, metal clamp, then the wooden one would be obsolete. Only replace what you need to replace.
20 years. There are plenty of shops that would purchase new equipment regardless of its age. The big money company gets a new one, and the little guy gets a good deal on an old one. The thing you need to do is see if you can find a buyer for the equipment before you refurbish it.
when they are ready to fall apart and when everytime you use it you have to repair it.
