1. The structural parts are analyzed and designed by the advanced Finite Element Analysis. It provides a detailed analysis for structural stress/strain conditions,and ensures excellent machine rigidity and lifetime stability. 2. Pre-tensioned ballscrews on X, Y, Z axes ensure accuracy and eliminate positioning error. 3. The end face of spindle stock, screw support faces and block contact faces are fully Hand-scraped to increase machining accuracy and feeding smoothness.
4. The machine structure is constructed from high quality Meehanite cast iron an.d stress released to ensure great rigidity and precision.
5. Over sized column and bed, assuring extra high rigidity of machine frame.
