Why Tight Tolerance Increases Cost
8/11/2026
Not every feature requires extreme precision.
Do you really need ±0 .01mm tolerance?
Not every feature requires extreme precision.
Overly tight tolerances can increase:
❌Machining time
❌Inspection time
❌Tool requirements
❌Manufacturing cost
A better approach:
Apply tight tolerance only where function requires it .
Smart tolerance design creates better products at lower cost .
