ABSTRACT
A 4-axis ultra-precision lathe with a rotary B axis is introduced, including its overall structure features and performance parameters and also its air motorized spindle, air linear guide and rotary worktable are described. Open PA NC system is used and ultra-precision grating is employed as full closed feedback device. The rotary accuracy of spindle is 0.05 μm, the straightness error of guide is 0.15 μm/200 m and the displacement resolution is 2 nm and the rotary accuracy of B axis is 3''. In order to verify comprehensive performance of the lathe, large flat surface, semi-sphere, complex curved surface and parabolic are machined. The result shows that by using the lathe, mirror surface can be obtained.
