Our processing procedures

1. Process Details

1. Upload Drawings/Samples: Customers can send 2D/3D drawings (common formats such as CAD, PDF) or physical samples to our official email or online service platform. Our engineers will confirm the part structure, material requirements, and processing difficulty within 24 hours.
2. Professional Quotation: Based on the drawing/sample evaluation results, we provide a transparent quotation plan, including material costs, processing fees, surface treatment fees, and delivery cycle. There are no hidden costs, and we can adjust the plan according to the customer’s budget or batch requirements.
3. Precision Production: After the customer confirms the quotation and signs the contract, we start formal production. The entire production process is monitored in real time (including parameter debugging of CNC lathes, material cutting, and semi-finished product inspection) to ensure that the processing process is consistent with the drawing standards.
4. Strict QC Inspection: We implement a “three-level quality inspection system” in accordance with ISO 9001:2000 quality management system standards:
   • Pre-production: Review drawings and test material performance;
   • In-production: Randomly inspect semi-finished products to avoid batch defects;
   • Post-production: 100% full inspection of finished products (using precision measuring instruments to verify tolerance and surface quality), and only deliver products with a pass rate of 99.8% or higher.

1. What materials can your CNC Turning service process? Are there any material restrictions?

   Our CNC Turning service supports a variety of mainstream metal and non – metal materials, with no special material restrictions. The core applicable materials include:

   Metals: Stainless steel, aluminum alloy, brass, titanium alloy, etc. (All have been verified for processing performance to ensure cutting stability and part quality);

   Non – metals: Engineering plastics (such as ABS, POM), rubber, etc. (Suitable for parts that require wear resistance or elasticity, such as customized plastic suction cup hooks).

   If you have special material requirements (such as high – temperature alloys), you can provide the material parameters, and our engineers will conduct a feasibility assessment and develop a customized processing plan.

2. What accuracy can CNC Turning parts achieve? How to ensure stable accuracy?

   Relying on high – precision equipment and strict quality control, the tolerance of our CNC Turning parts can be stably achieved at ±0.005mm; for high – precision demand scenarios such as core watch parts, the accuracy can be further optimized to ±0.003mm.

   The specific accuracy guarantee measures are as follows:

   Equipment level: Equipped with more than 100 high – precision processing equipment such as 5 – axis machining equipment, and regularly calibrate the equipment parameters to ensure accurate processing benchmarks;

   Process level: Implement the “three – inspection system” under the ISO 9001:2000 quality management system – pre – production drawing review, in – production semi – finished product spot – check, and 100% full – inspection of finished products after production;

3. What information is needed to customize CNC Turning parts? Can we cooperate without a complete drawing?

   The core information required to customize CNC Turning parts is 2D/3D drawings, supporting mainstream formats such as CAD, PDF, STP, and SolidWorks. The drawings should clearly mark the part dimensions, tolerances, materials, and surface treatment requirements.

   If you don’t have a complete drawing yet, cooperation is still possible if you only provide a physical sample: We can use 3D scanning equipment for reverse engineering, restore the sample structure and generate digital drawings. After you confirm the details, we will start the processing to ensure that the parts fully meet your requirements.
