Yes. Depending on project requirements, we can provide material certificates, dimensional inspection reports, first article inspection documentation, and other quality records. Required documentation should be specified when requesting a quotation.

 

10. Can you handle tight-tolerance and precision components?

Yes. We manufacture precision components with tight dimensional and geometric requirements. Critical features can be inspected during production and during final inspection using appropriate measuring equipment.

 

11. Do you provide surface finishing after CNC machining?

Yes. Surface finishing can be arranged according to the part requirements, including anodizing, passivation, plating, polishing, brushing, bead blasting, and other specified finishes.

 

12. How long does CNC machining take?

Lead time depends on part complexity, material availability, quantity, machining process, surface treatment, and inspection requirements. A more accurate delivery schedule can be confirmed after reviewing the drawing and order quantity.
