CNC spares buying guides
Sourcing spares for a CNC system that the OEM stopped supporting years ago is mostly a problem of identification. These guides cover the part-number grammar each manufacturer uses, what the condition grades really mean, and how to write a request for quote that comes back with a price instead of a question.
Written for maintenance engineers and purchasing teams keeping older machinery running. Where interchangeability cannot be confirmed from manufacturer documentation, we say so rather than guess.
