Typical hourly rates for CNC milling aluminum parts range from $50 to $120, depending on machine type, tooling, and precision. Custom quotes are available for specific projects.
Common Aluminum CNC Machining Questions (FAQ)
How much does it cost to get aluminum machined?
The cost varies by part complexity, material, and batch size. Single prototypes often have a higher unit cost due to setup time, while large-volume production reduces cost per piece.
Can CNC machines cut aluminum?
Yes, CNC machines can cut aluminum efficiently. Using proper tooling, spindle speeds, feeds, and coolant ensures high surface quality and dimensional accuracy. Aluminum’s softness and machinability make it ideal for CNC processing.
How much does CNC milling cost per hour?
Hourly rates for CNC milling typically range from $50 to $120. Costs are influenced by the type of machine (3-axis, 4-axis, 5-axis), material, complexity, and post-processing requirements such as anodizing or polishing.
What is CNC machined aluminum?
CNC machined aluminum refers to aluminum components manufactured using computer-controlled machinery. The process provides high precision, consistent tolerances, and smooth surface finishes suitable for industrial applications.
What is the standard tolerance for CNC aluminum machining?
Standard tolerances depend on the part size and machining type. Typically, general tolerances follow ISO 2768 for linear dimensions and angles. Fine tolerances can be achieved down to ±0.01 mm for milling and ±0.02 mm for turning.
How accurate can a CNC machine be?
Accuracy depends on machine type, tooling, and material. Modern CNC machines can achieve precision up to ±0.005 mm, but most industrial applications use ±0.01 mm to ±0.02 mm as standard.
