1. The 5-Axis High-Speed Precision Milling Machining Center adopts the design of fixed support bearings at both ends with appropriate pre-tension, and the rain end of ball screws are fixed with high-precision angular thrust bearings to improve rigidity. 2.The self-oscillation frequency of the 5-axis High-Speed Precision Milling Machining Center is increased to within the normal use range to ensure high bear machining accuracy and make the servo system easy to adjust.
