Frequently Asked Questions (FAQ)
-
Q: What file formats do you accept for custom machining?
A: We accept STEP, IGES, STP, DWG, DXF, PDF, and common 3D formats like SolidWorks and AutoCAD. Our engineering team can also work from sketches or samples. -
Q: Can you achieve 0.002mm tolerance on all features?
A: This tolerance is achievable on most turned and milled surfaces, but it depends on material, geometry, and part size. We will review your drawing and confirm the achievable tolerances before production. -
Q: What is the minimum order quantity (MOQ) for custom parts?
A: We have no strict MOQ for prototypes – we can machine as few as 1 piece. For production runs, we typically recommend 100+ pieces for cost efficiency, but smaller quantities are welcome. -
Q: How do you ensure the quality of 8-32 threads?
A: We use dedicated thread mills and taps, followed by Go/No-Go gauge inspection. For critical applications, we also perform thread pitch diameter measurement and torque testing. -
Q: What materials can you machine with 8-32 threads?
A: Common materials include stainless steel, aluminum, brass, carbon steel, and engineering plastics. We can also machine titanium, Inconel, and other alloys upon request. -
Q: Do you offer surface finishing services?
A: Yes, we offer a variety of finishes including as-machined, anodizing (clear, color, hard coat), passivation, zinc/nickel plating, black oxide, powder coating, and polishing. -
Q: What is your typical lead time?
A: Standard lead time is 7–15 working days after drawing approval and deposit. Rush orders can be completed in 3–5 days for an additional fee. -
Q: Can you provide certificates of compliance or material test reports?
A: Yes, we can provide mill certificates, dimensional inspection reports, and material certificates (e.g., EN 10204 3.1) upon request at no extra cost.
