FAQ
|
Q1: |
What tolerance can you achieve on high precision parts? |
|
A1: |
We commonly hold ±0.01 mm on standard high precision features and ±0.005 mm on ultra-precision critical dimensions. Final capability depends on the material, part structure, quantity, and inspection requirements. |
|
Q2: |
Do you provide CMM inspection reports? |
|
A2: |
Yes. Every order can include a dimensional inspection report with CMM data. We can also provide material certificates, surface roughness reports, and RoHS documentation upon request. |
|
Q3: |
What is your minimum order quantity? |
|
A3: |
We accept orders starting from 1 piece for prototyping. For production runs, we optimize tooling and fixturing to offer cost-effective pricing for larger quantities. |
