What's a Typical CNC Milling Speed Range for Aluminum?

As mentioned earlier, the typical milling speed range for aluminum in CNC machining（https://www.jtrmachine.com/cnc-machining-service） falls between 60 and 120 meters per minute (m/min). This applies to most commonly used aluminum alloys like 6061 and 7075 when using carbide cutting tools.

However, this range can be broader depending on the specific factors mentioned above. Here's a breakdown:

Softer aluminum (1100 series): You might be able to achieve speeds exceeding 120 m/min due to its good machinability.
Harder aluminum alloys (6061-T6, 7075-T6): Speeds might fall closer to the lower end of the range (60-80 m/min) to maintain tool life and achieve a good finish.
High-speed machining (HSM): This specialized technique with appropriate tooling can reach speeds of up to 400 m/min for certain aluminum alloys. However, HSM requires a rigid machine and careful setup to avoid tool chatter and vibration.

Remember, these are just starting points. It's important to consult specific recommendations for your chosen aluminum alloy and cutting tool combination.
