In modern industrial production, bolts are an important fastener, and their quality is directly related to the safety and reliability of the product. However, during the production and use of bolts, bending deformation may occur due to various reasons, which not only affects the appearance of the bolts, but may also cause them to fail to function properly. In order to solve this problem, as a fully automatic straightening machine manufacturer, we are committed to providing customers with efficient and


A proposed automatic straightening solution for 183–720 mm steel shafts and bars, covering multi-diameter runout measurement, 1–5 correction points, adaptive pressing and final verification.


A through-feed roller straightening solution for long round steel bars, covering roll selection, extended support, safe handling and sample-based verification.



Learn how shaft straightness, circular runout, total runout and shop-floor TIR differ—and what datum, probe path and acceptance method a straightening project needs.


A gearbox shaft straightening solution must measure journals and gear pitch diameter separately, protect teeth and radial holes, control springback and remeasure every critical station.
We have successfully completed the sample testing for a highly valued client from South Korea, and the results have far exceeded expectations. This accomplishment not only showcases our technical prowess but also solidifies our position as a reliable partner in the manufacturing industry. The Challenge Presented by the Medical Bits The project involved the production of specialized medical bits. These components had a unique set of specifications that posed a considerable challenge to our machinery and technical teams. The dimensions


A sample-based straightening solution for small-diameter medical drill components, covering low-force measurement, functional datums, micro-correction, automatic handling and documented verification.


A proposed automatic axle shaft straightening solution for 1000–1350 mm flanged shafts, covering journal, shaft, spline and flange-hole runout requirements.
