Rail Restoration:Rail Repair, Rail Inspection

Acceptance standards for rail grinding are becoming increasingly stringent, requiring profile deviations to be controlled within +0.2 mm. This article outlines the technical essentials of pre-grinding, preventive grinding, and corrective grinding, and explores how high-quality grinding wheels facilitate high-precision profiling, thereby ensuring operational safety and extending rail service life.
