Q1: What is the typical lead time for stainless steel CNC parts?
A1: We offer rapid prototyping in as fast as 3–5 days, and batch production of stainless steel CNC components within 7–15 working days.
Q2: Can you achieve tight tolerances with stainless steel CNC machining?
A2: Yes. We routinely achieve tolerances down to ±0.01mm on stainless steel CNC parts, especially with SS304 and SS316 materials.
Q3: Do you offer surface finishing for stainless steel machined parts?
A3: Absolutely. Our stainless steel CNC machining services include polishing, passivation, electropolishing, and custom finishes based on your design.
Q4: Can I get a prototype made before full production?
A4: Yes. We encourage stainless steel CNC prototypes to validate form, fit, and function before scaling.
Q5: What information should I provide for an RFQ?
A5: Please share your 2D/3D files (STEP, DWG, or PDF), material grade (e.g., SS304), quantity, surface finish, and tolerance requirements for a fast quote.
