This video explains the main functions and practical uses of custom precision CNC machined parts in a clear, step-by-step format. Watch a full walkthrough of CNC turning and 3/4/5-axis milling on 304 stainless steel and aluminum alloys, including tempering, hardening, deburring, and polishing. See how ±0.001mm tolerances are achieved for automation equipment, and learn how to specify materials, finishes, and low-volume orders from 1 piece to 10,000 pieces per month.
