CNC Precision Isn’t Always Better

Have you ever think: “tighter tolerance = more professional.”

Now I realize: a lot of ±0.01 mm tolerances are completely unnecessary.

What happens instead:

• costs go way up
• machining takes longer
• yield gets worse

For many assemblies:

±0.05 mm is already more than enough.

Now I only use tight tolerances for:

• bearing fits
• alignment features
• sliding components

Everything else gets loosened up.
