Hybrid Sphere CNC Lathe

The trajectory of B axis can be closed to ball shape. The result of roundness can achieve to ± 0.005mm which will be better than conventional lathe, X, and Z axis simultaneously running.

Burnishing is the process to extrude the surface by pressure, which will not consume the material as grinding. Instead of modifying the dimension of workpiece, burnishing will re-rank the metal molecules to remove the machining trace so that the surface can be strengthened and enhanced 10% to 30%. The roughness can achieve to Ra 0.1 ~ 0.2μm.
