FAQ1. What materials are supported for CNC machining?Common metals: Aluminum alloys, stainless steel, copper, titanium alloys, and tool steel.Common plastics: ABS, POM (Delrin), PC, PMMA (Acrylic), Nylon, etc.Special materials: Composite materials or customer-specified special materials (subject to feasibility confirmation). 2. What tolerance of precision can CNC machining achieve?Typical tolerance range: ±0.002mm to ±0.01mm (depending on the material and part complexity).High-precision needs: Ensured using advanced equipment and inspection tools.Surface finish: Achievable up to Ra0.4 or better, with various surface finishing options available. 3. Does CNC machining support small-batch orders?Yes, small-batch customization (e.g., 1-10 pieces) is supported, as well as medium and large-scale production.Rapid prototyping: Typically completed within 3-7 business days from order placement to delivery. 4. What information should customers provide?3D CAD files: Recommended formats include STEP, IGES, or STL files.2D drawings (if available): Indicate dimensions, tolerances, materials, and surface treatment requirements.Special instructions: Include any additional machining or assembly requirements.5. How is the machining cost calculated?
Key factors: Material cost, machining time, part complexity, and surface finishing requirements.
Transparent quotes: Detailed quotes are typically provided within 1-2 business days after receiving drawings.
Discounts: Long-term clients or bulk orders may qualify for price reductions.

6. What is the typical production lead time?
Small-batch parts: Usually completed within 3-7 business days.
Large-batch orders: Lead times depend on the order quantity and complexity, typically 1-4 weeks.
Rush services: Priority production can be arranged based on customer requirements.

7. What surface finish options are available?
Common finishes: Anodizing, electroplating, sandblasting, polishing, and heat treatment.
Surface coatings: Powder coating, painting, etc.
Custom finishes: Support for customer-specified special surface treatments.

8. How do you ensure product quality?
Quality inspection: Every part undergoes rigorous checks (e.g., dimensional measurements, surface inspection) before delivery.
Inspection equipment: Includes CMM (Coordinate Measuring Machine), height gauges, roughness testers, and more.
Quality standards: Manufacturing processes comply with ISO 9001 quality management standards.
