How much does machining cost per hour?
CNC machining hourly rates typically range from $75 to $200+ per hour depending on machine type, part complexity, tolerances, and materials. Swiss turning and 5-axis milling for aerospace-grade materials like titanium generally command higher rates than standard 3-axis work.
