    Frequently Asked Questions

    Answers to common CNC milling queries to resolve your project concerns quickly

    Q: What types of parts are suitable for CNC turning? +
    CNC turning is mainly applicable to rotary parts, including various shafts, sleeves, pin shafts, fasteners, joints, valve bodies and other components. It is the mainstream processing technology for parts with circular cross‑sections.
    Q: How to avoid deformation during the processing of long shaft parts? +
    We customize clamping solutions according to the length‑diameter ratio of parts. Auxiliary tooling such as follow rests and tailstocks are adopted, together with layered cutting and controlled cutting volume processes to minimize processing deformation.
    Q: What is the difference between swiss turning and conventional turning? +
    Swiss turning is suitable for slender shafts and small precision parts. With moving materials and fixed tools during processing, it delivers superior concentricity and surface quality, ideal for mass production of small high‑precision parts. Conventional lathes are more suitable for large‑diameter and standard‑length parts with a wider range of applications.
    Q: Can turning parts be strengthened by heat treatment? +
    Yes. We provide supporting heat treatment processes including quenching and tempering, hardening and carburizing to improve the hardness, wear resistance and mechanical properties of parts, making them applicable for high‑load and high‑wear working scenarios.
    Q: What accuracy and surface roughness can CNC turning achieve? +
    Standard CNC turning can reach a dimensional accuracy of ±0.02mm, and precision turning can achieve a high accuracy of ±0.005mm. The conventional surface roughness can reach Ra1.6μm, and it can be optimized to Ra0.8μm or below through finish turning and polishing, meeting high‑precision requirements for precision assembly, sealing and transmission applications.
    Q: Does CNC turning support small‑batch prototyping and mass production? +
    Absolutely. We support single‑piece prototyping, small‑batch trial production and large‑scale mass production. With highly adaptable equipment and mature processes, we guarantee short lead times for prototyping and stable mass production quality. We ensure consistent part dimensions, on‑time delivery and reliable product quality to meet various project needs including R&D trial production and batch supply.
