FAQs About Our Custom Parts Machining
What types of CNC machining services do you offer?
We provide CNC machining for custom parts, including milling, turning, 5-axis machining, turn-mill, and grinding.
We support both prototyping and small-batch production.
What is your minimum order quantity?
We do not require a minimum order quantity.
You can start with a single prototype or scale to small-batch production based on your needs.
What tolerances can you achieve?
6 CNC machining capability: tolerance up to ±0.002 mm .
Actual tolerance depends on material and part geometry.
How fast can you deliver parts?
Lead time depends on part complexity and quantity.
Most prototypes can be completed within a few days, and production orders follow agreed schedules.
What materials can you machine?
We machine a wide range of materials, including aluminum, stainless steel, titanium, brass, and engineering plastics such as ABS, POM, and PEEK.
How do I get a quote?
You can upload your CAD files or drawings directly.
We will review your design and provide a clear quotation based on material, quantity, and requirements.
Can you help improve my part design?
Yes. We provide design for manufacturability (DFM) feedback before production.
This helps reduce cost, improve machining efficiency, and avoid production issues.
Do you support international customers?
Yes. We serve customers worldwide and provide reliable global shipping from our Shenzhen facility
