High Precision Turning

Parts like servo motor shafts, precision spindles, and valve cores need dimension tolerance of ±0.01mm and roundness of 0.01mm as normal requirements. Hayi Technology's high precision turning service uses ultra precision lathes. Spindle runout is <0.005mm. We use full closed-loop linear scales with resolution of 0.001mm. For example, an aerospace parts maker needed a titanium alloy shaft with coaxiality of 0.01mm. We used a hydrostatic spindle and ceramic bearings. The first part passed. The client said this precision matched what they used to import from Germany. This case shows high precision turning can replace grinding. Our MOQ is 1 piece.

Hard Turning Replaces Grinding – 50% Lower Cost

For hardened steel above HRC60, traditional methods need grinding. Our high precision lathe can do hard turning directly. Surface roughness reaches Ra ≤0.1μm. We can machine stainless steel, bearing steel, titanium alloy, ceramic, and PEEK. Our inspection equipment includes a CMM (0.5μm accuracy), a roughness tester, and air gauges. We hold ISO9001:2015 certification. Each batch comes with a full dimension inspection report. All machining is done in a temperature controlled workshop. Our high precision turning service is a cost effective alternative to grinding.

Precision parts development needs fast verification. Our custom sample time is 1 day for simple parts. Batch order lead time is about 15 days. Payment: 30% deposit for standard products, 50% deposit for custom products, balance before shipment. Trade terms: EXW, FOB, DDP. During production, we send photo or video updates. If any quality problem occurs, we talk immediately and improve after we find the cause. We have a dedicated after-sales person. Many clients do not know hard turning can replace grinding. Our technicians can help you evaluate if your part is suitable for hard turning. You can help your client cut costs by up to 50%.
