Precision machines and the parts they make are defined by standards: how a quality system works, how accuracy is measured, how a machine is made safe, how a drawing is read and who is allowed to see the data. This reference defines each one in plain language and explains what it means for the people who build, sell and use machines.
Precision machines are built, sold, moved and run inside a web of standards. The same requirement looks different depending on where you sit.
The company making the parts, or building the machine.
A dealer, broker, auctioneer, rebuilder, or a shop selling surplus equipment or material.
The shop that will run the machine, or the customer receiving the parts.
