Founded in 1990, YIRS specializes in Swiss-type, fixed-head, and multi-axis turn-mill precision machining. Based on customer drawings or samples, the company integrates turning, milling, drilling, tapping, boring, threading, and 3D contour machining. Completing multiple processes in a single setup reduces repositioning errors and improves the accuracy and productivity of complex components. YIRS processes bars from approximately φ2 to φ52 mm in diameter and up to approximately 600 mm in length, with tolerances reaching approximately ±0.005 mm. It serves the automotive, motorcycle, bicycle, agricultural machinery, industrial hardware, medical, electronics, communications, optical, and fluid-power sectors. Its integrated services—including plating, anodizing, grinding, laser marking, heat treatment, and assembly—help customers shorten supply chains, reduce management costs, and accelerate production.
