Expert answers to the most common questions about CNC machining, sheet
metal fabrication, tolerances, materials, and lead times
What tolerances can CNC machining achieve?
Standard CNC machining tolerances: ±0.1mm
(±0.004") for most applications. This works for 90% of industrial
parts including machine frames, brackets, and housings.
Precision CNC machining: ±0.05mm (±0.002") for
critical dimensions. Used for bearing seats, fitting surfaces, and
tight assemblies.
High-precision machining: ±0.01mm (±0.0004") for
ultra-critical applications like medical devices, aerospace
components, or measurement equipment.
Expert Tip:
Specify tighter tolerances only where needed. This reduces cost
and lead time while ensuring quality where it matters most.
