Hey everyone,

I’ve been working on improving the accuracy and finish of machined components and wanted to get insights from experienced machinists.

Specifically, I’m curious about optimizing the manufacturing process for CNC aluminum parts. What are the best techniques, cutting tools, and parameters you’ve found effective for achieving tight tolerances and smooth finishes?

Do factors like coolant type, spindle speed, or material grade significantly affect the results? Any practical tips or recommended setups for small-batch versus mass production would be greatly appreciated.
