About Yueyi Precision

Expert Swiss CNC Machining for Complex Geometries

At Yueyi Precision, our Swiss CNC machining facility is designed to handle the most challenging parts that traditional lathes cannot. Unlike standard turning, our Swiss-style machines use a sliding headstock and guide bushing, providing maximum support near the cutting tool. This makes us the ideal partner for producing long, slender, and high-aspect-ratio precision swiss turned parts without deflection or vibration.
 
With over 20 years of experience in Swiss screw machining, our certified engineers ensure ±0.01mm tolerance on every project. Learn more about our Swiss machining capabilities
