In Manufacturing, and in particular, the Machine Tool industry, the environment inside a machine is usually very extreme. A CNC machine uses cutting fluids and other lubricants to aid in the ‘cutting’ of steel in the shaping of a part. These fluids, mixed with metal shavings and other solids, causes excessive servo motor failure.
When your CNC machine outfitted with Fanuc system stops working, the person running it or maintenance personal must quickly figure out the root-cause and then formulate a plan to get the machine running again. Seems simple, but rarely is it simple or easy.
Being a Fanuc repair facility, a common happening is that we will get a Fanuc motor or amplifier in for service, then go through our process to evaluate and we find out: the unit runs fine.
