What is the most precise machining method?
Quick answer: EDM and precision grinding lead for ultra-tight tolerances, while modern CNC machines routinely work within a few microns.
EDM and precision grinding lead for ultra-tight tolerances, while modern CNC machines routinely work within a few microns.
- Match the process to the material and part geometry.
- Use EDM for hard conductive metals and intricate features.
- Use precision grinding for exceptionally accurate surfaces and dimensions.
- Control temperature, tooling, measurement, and machine setup to hold the tolerance.
Good to know: The required accuracy, not the most impressive number, should determine the process for aerospace, medical, automotive, or custom parts.
