Frequently Asked Questions (FAQs)
1. What is CNC turning and how is it different from CNC milling?
CNC turning uses a lathe to rotate the workpiece, shaping it with cutting tools for cylindrical or round geometry. CNC milling, on the other hand, moves the cutting tool across a stationary workpiece to create complex shapes, slots, and holes. Turning is ideal for producing shafts, bushings, and round parts; milling excels at flat surfaces and prismatic shapes.
2. Do I need specific certifications to supply CNC turned parts?
While not always required, certifications such as ISO 9001 (Quality Management Systems) or AS9100 (for aerospace) greatly enhance credibility and open doors to clients in regulated industries. Many high-tech sectors expect documented quality control and traceability.
3. Which materials can I work with as a CNC turned parts supplier?
Most CNC lathes handle metals like steel, stainless steel, aluminum, brass, and copper alloys, as well as engineering plastics like POM, nylon, and PTFE. Choice of material depends on the client’s application and industry standards.
4. How can I reduce shipping costs for custom turned components?
Plan production schedules to combine multiple orders into a single shipment, reducing per-unit costs. Use efficient packaging to maximize the number of parts per box and choose shipping carriers based on delivery speed and reliability. For high-value or international shipments, consider insurance and tracking.
5. What are the biggest mistakes to avoid when starting a CNC turned parts supply business?
Common pitfalls include underestimating equipment and setup costs, neglecting quality control procedures, failing to invest in skilled staff, and ignoring the importance of strong customer relationships. To succeed, prioritize quality, clear communication, and process efficiency right from the start.
Conclusion
Becoming a CNC turned parts supplier is an exciting and potentially rewarding venture. The market demand spans many industries, but success requires technical know-how, investment in technology, and a commitment to customer satisfaction. Pay close attention to quality, logistics, and efficient operations—these are the foundation stones for building a trusted and profitable CNC parts supply business.
