Frequently Asked Questions (FAQs)

Frequently Asked Questions About Custom Machining Factories in China

How do I get a quote for custom machining parts?

To get a quote for custom machining parts, you typically need to provide the factory with your CAD data and project information. You can upload your files through the factory’s website or send them directly via email. For example, you can click on the “Get Quote” button on the website and submit your 3D data files in formats like STEP, IGES, X_T, or STL, along with any 2D files if dimensional tolerances are required. The factory will then contact you within a short period, usually 12 hours, with a quotation and a manufacturing feasibility analysis.

What materials can be used for CNC machining?

Custom machining factories in China can process a wide variety of materials to meet your needs. These include aluminum (such as AL 6061-T6, 6063, 7075), stainless steel (like 303, 304, 316L), copper, iron (e.g., 4140, Q235), titanium, and various engineering plastics like PEEK, Nylon, and PMMA. This material diversity ensures you can select the most suitable material for your specific application, optimizing product performance and resilience.

What is the typical lead time for custom machining orders?

The lead time for custom machining orders can vary depending on the complexity of the parts, the quantity, and the machining requirements. For simple parts, proofing can be as quick as one day, while complex parts may take up to 3 days. For batch production, delivery times can range from 4 to 7 days for simple parts and up to 20-25 days for larger or more complex orders. The exact delivery time will be provided in your quotation.

How accurate are the tolerances in CNC machining?

CNC machining offers high accuracy and precision. Tolerances can be as tight as ±0.01mm to ±0.005mm, depending on the specific machining process and equipment used. For instance, automatic lathes can achieve tolerances of ±0.01mm, while Citizen swiss-type lathes can achieve ±0.005mm. The final tolerance also depends on factors such as part size, design geometry, material, and surface finish.

What kind of surface treatments are available for CNC machined parts?

Custom machining factories in China offer a range of surface treatments to meet your requirements. These include anodizing, electroplating, PVD, nickel plating, sandblasting, powder spraying, polishing, multi-color anodizing, and spray painting. Additionally, they can provide post-processing services like assembly fitting, fastening, metal embedding, sanding, and silk screen printing. This ensures your parts can have the desired appearance and performance characteristics.
