CNC precision machining is not the same as standard CNC machining. It comes down to tolerances, repeatability, and quality systems. Standard machining might hold 0.1mm. Precision holds 0.025mm or tighter. Some aerospace and medical parts require 0.005mm.
Getting those numbers requires the right equipment, tooling, environment, and inspection. This guide covers what precision CNC machining actually means for engineers and procurement managers.
