Frequently Asked Questions (FAQ)

1. What information do you need to provide a quote for custom CNC machined parts?
To provide an accurate quotation, we require your technical drawing (in PDF or STEP format), material specification, quantity, and any specific surface finish or plating requirements.

2. What is the difference between CNC turning and CNC milling?
CNC turning is used for cylindrical parts where the workpiece rotates, and the cutting tool moves in a linear fashion. CNC milling is used for more complex, prismatic parts where a rotating multi-point cutter moves around a stationary workpiece.

3. Can you machine parts from our provided raw material?
Yes, we offer machining services for customer-supplied materials, subject to a quality check upon receipt.

4. What are the benefits of using Swiss-type CNC lathes?
Swiss machining is ideal for long, slender, and complex parts as it provides superior support close to the cutting tool, minimizing deflection and allowing for extremely tight tolerances and intricate features in a single operation.

5. Do you provide material certification for your CNC components?
Yes, we provide full material traceability and certification (e.g., 3.1 Mill Certificate) as per EN 10204 or equivalent standards for all critical components upon request.

6. What is the lead time for a prototype order?
For prototype orders, we can often reduce the lead time to 2-3 weeks depending on the part complexity and material availability.

7. How do you ensure quality control in your CNC machining process?
Our quality control process includes in-process inspection, First Article Inspection (FAI), and final inspection using calibrated tools like CMM, micrometers, and profilometers to verify all critical dimensions.

8. What is the minimum and maximum order quantity you accept?
We are highly flexible, accepting orders from a single prototype piece to high-volume production runs of millions of parts.

9. Can you assist with secondary operations like plating and anodizing?
Absolutely. We manage a vetted network of partners for all secondary operations, providing a single-source solution for finished, ready-to-install components.

10. What file formats do you accept for my part design?
We accept all major 2D and 3D formats, including PDF, DWG, STEP, IGES, SLDPRT, and X_T.

11. What is passivation for Stainless Steel parts?
Passivation is a chemical process that removes free iron from the surface of stainless steel and promotes the formation of a passive oxide layer, enhancing its natural corrosion resistance.

12. Why is Brass C36000 so popular for machining?
Free-cutting brass C36000 offers the best machinability of all copper alloys, allowing for high production speeds, excellent surface finish, and extended tool life.

13. What industries do you primarily serve with your CNC components?
We serve a wide spectrum, including Automotive, Aerospace, Medical, Oil & Gas, Electronics, Defense, and Industrial Automation.

14. Do you offer design for manufacturability (DFM) services?
Yes, our experienced engineers can review your drawings and suggest modifications to simplify manufacturing, reduce costs, and improve performance without compromising the design intent.

15. What are your payment terms for new international customers?
For new customers, we typically require a 50% advance with the purchase order and 50% before shipment. Terms can be reviewed for established relationships.
