FAQ

Q1: My product has a complex structure with deep cavities and thin walls. Can you guarantee the machining precision?

A: Of course! Handling complex structures is our specialty. For deep cavity machining: Our equipment is highly rigid and equipped with long-bladed cutting tools and a professional cooling and chip removal system, effectively ensuring machining efficiency, sidewall perpendicularity, and bottom surface finish for deep cavities.

For thin-walled and complex curved surfaces: Our experienced engineers effectively control machining deformation and ensure final dimensional accuracy by optimizing CNC programming strategies (such as using small depths of cut and high-speed light cutting) and clamping schemes. We are equipped with a coordinate measuring machine to rigorously inspect all critical dimensions, ensuring 100% qualified delivery.

Q2: What specific benefits does "four-axis simultaneous machining" offer for my box-type parts?

A: "Four-axis simultaneous machining" brings you both increased efficiency and precision. For box-type parts that require machining multiple surfaces, traditional three-axis machine tools require multiple re-clampings, while our four-axis CNC can complete the machining of all four surfaces except the bottom surface in a single clamping. This brings two core advantages: Reduced repetitive positioning errors: Avoiding the cumulative errors caused by multiple clampings, resulting in higher overall part positional accuracy. Significantly Improved Processing Efficiency: Reduced clamping and alignment time shortens the entire manufacturing cycle, saving you time and costs.

Q3: I'd like to make a prototype or sample first. Do you accept small batch or sample orders?

A: Yes! We highly welcome and value rapid prototyping and small batch orders. Our comprehensive equipment fleet (including multiple small and medium-sized CNC machining centers) can be flexibly deployed to quickly respond to your prototyping needs. We understand that prototyping is a crucial step in project success, and we will provide you with high-precision samples with the same professional attitude to help your project move forward quickly.

Q4: What materials do you usually process? How efficient is your aluminum parts processing?

A: We process a wide range of materials, including: Metals: various steels, aluminum alloys (such as 6061, 7075), copper alloys, etc. We have extensive experience and highly efficient solutions, especially in aluminum parts processing. By using specialized tools and optimized cutting parameters, our equipment achieves extremely high material removal rates, significantly shortening your delivery time while ensuring surface finish and precision. Q5: My part is a non-standard design. Can you complete non-standard customization?

A: Absolutely! Our core service is precision machining of non-standard parts. Our engineering team excels at handling various complex and unconventional part designs. Please feel free to provide your 3D drawings and technical requirements. We will conduct a professional process review and provide feasible machining solutions and technical suggestions to ensure your design is accurately translated into a physical product.

Q6: How long does the entire process take from inquiry to delivery?

A: Delivery time depends on the size, complexity, and quantity of the parts. Generally, our process is very efficient:

Q: After receiving your clear drawings and technical requirements, we promise to provide a detailed quotation within 24 hours.

Production: For sample orders, we strive to complete them within 3-7 days; for bulk orders, we will provide an accurate delivery date after assessing the specific process and ensure on-time delivery through efficient production scheduling.
