FAQ (FAQ)

Question 1: Is the quality of Chinese CNC suppliers reliable? Can they handle tight tolerances?

Answer: Absolute. Top Chinese CNC suppliers, especially those that invest heavily in technology (e.g. with advanced 5-axis machines) and strict quality control systems (CMMS, ISO certification), are conventionally implemented and maintained at ±0.005mm (±0.0002)") Even more refined key features. Well-known suppliers are fully capable of matching or exceeding Western quality standards at competitive costs.

Q2: Why is 5-axis CNC machining essential, and when do I need it?

A: Traditional 3-axis machine moves cutting tools along the X, Y and Z axes. 5-axis machining adds rotation around two of the axes (usually A and B or C). This allows the cutting tool to approach the workpiece from almost any angle in a single setup. You need 5 axes:

• Highly complex geometric shapes (impeller, turbine blade, ergonomic shape)
• Need to access the tool’s functionality from multiple angles (deep pocket, undercut)
• Parts that require excellent finishes on complex curves
• Reduced settings, which improves accuracy, reduces lead times, and reduces the cost of complex parts.
  Vendors like Greatlight, specializing in using these advantages to maximize.

Q3: Which materials can be used as the top suppliers of China CNC suppliers that Greatlight can usually handle?

A: Leading suppliers offer a wide range of material functions:

• Metal: Aluminum (various alloys), stainless steel (303, 304, 316, 17-4PH, etc.), steel (gent, tool steel), brass, copper, titanium (grade 2, 5), Inconel, Inconel, magnesium.
• plastic: ABS, polycarbonate (PC), nylon, POM (Delrin), Peek, Ptfe (Teflon), Ulem (PEI).
  Greatlight highlights a wide range of expertise in particular Customizable metal For demanding applications.

Question 4: What is the typical lead time for customized parts from China?

A: Delivery time varies greatly depending on complexity, quantity, surface finish requirements and supplier workload. Here is a rough guide:

• Prototype (1-10 PCs): There are expedited options for 3-10 days (Wayken famously offers certain work 24-72 hours).
• Low volume production (10-1000 PC): 1-3 weeks.
• High volume production (more than 1000 PCs): 4-8+ weeks (discuss precise arrangements as soon as possible). Suppliers like Greatlight to focus on Quick customization Minimize delivery time.

Q5: How to make sure my design is manufacturing (Made Design-DFM)?

Answer: Top suppliers provide DFM analysis as their core service:

1. Share detailed design: Provides complete CAD files (steps, IGE) and GD&T drawings.
2. Request clear DFM feedback: Ask them to view the design to ensure feasibility, achievability, potential cost drivers and optimization recommendations.
3. Ask a question: Clarify substance selection and critical tolerances. The famous partners as mentioned above offer valuable DFM insights.

Question 6: What post-processing services are usually provided? Why is internally completed valuable?

Answer: Basic post-processing includes:

• Surface finish: Anodized (type II/III), electroplating (Ni, Cr, Zn, Ag), powder coating, polishing, bead/sand blasting.
• Secondary processing: Hit, heat treatment (hardening, annealing), laser engraving/marking.
  Internal finishing (as provided by Greatlight) Very valuable: It ensures consistency in quality control, greatly reduces total lead time by eliminating external suppliers, and simplifies logistics/payment through a single point of contact. This is the cornerstone of a truly one-stop service.
