Understanding pricing structures helps you get the best value from your chosen CNC precision machining company. Costs vary based on complexity, material, volume, tolerances, and turnaround time.
Material selection significantly impacts costs. Common materials like aluminum 6061 are less expensive than exotic alloys like Inconel or titanium. Part complexity affects machining time, with intricate geometries requiring more tool changes and setup time.
Tight tolerances increase costs because they require more careful machining, additional quality checks, and potentially specialized equipment. A CNC precision machining company typically charges premium rates for tolerances tighter than ±0.001".
Volume matters too. While prototype quantities may have higher per-piece costs due to setup time, production runs benefit from economies of scale. Some CNC precision machining companies offer volume discounts starting at 100 or 500 pieces.
