We specialize in tackling complex machining challenges. Our recent project involved the production of a large shaft for industrial machinery using our advanced 14-meter CNC long bed lathe.

[Characteristics of the large shaft]
● Length: 10 meters
● Diameter: φ350
● Primary use: Critical component in industrial machinery
● Precision requirements: High cylindricity and circularity for optimal performance

[Overcoming Machining Challenges]
● Controlling deflection due to the shaft's self-weight
● Preventing workpiece distortion during the machining process
● Maintaining high accuracy over the entire 10-meter length

[Machining Process]
● Cutting-Edge Equipment: Utilization of our 14-meter CNC long bed lathe
● Precision Setup: Careful adjustment of jig center height to counteract deflection
● Fine-Tuned Operations: Optimization of workpiece rotation speed and tool settings

[Our approach to provide high quality products]
● Continuous Improvement: Ongoing refinement of jigs and fixtures
● Process Optimization: Fine-tuning of machining conditions for each unique project

[Applications]
