Confirm incoterms, inspection video, warranty scope, control-language capability, and delivery of wear parts such as belts, seals, sensors, collets, and bearings. FAQ Can a used automatic lathe hold production tolerances? Yes, when measured geometry and repeatability suit the drawing tolerance; validate with a loaded test cut. What accuracy should buyers expect? Many sound used machines hold 0.01–0.03 mm, but capability varies by model, condition, tooling, and temperature control. Is a rebuilt machine always safer? No. Request an itemized rebuild report, before-and-after measurements, and proof of replaced components. Which failures are most expensive? Spindle failure, obsolete CNC drives, damaged guideways, and major hydraulic or bar-feeder faults usually carry the highest risk. Are Chinese suppliers suitable for export purchases? Yes, provided they have documented export cases, inspection procedures, compliant packing, responsive service staff, and stocked spares. When should I buy new instead? Choose new for very tight tolerances, advanced automation requirements, long warranty needs, or unavailable legacy parts. A used automatic lathe can be a high-return production asset when performance is proven rather than assumed. Contact a reliable Chinese supplier for an inspection report, machine video, spare-parts commitment, and current quote.
