A high precision vertical milling head structure was introduced.Two sets of four angular contact bearings were adopted and they were installed to support main shaft by means of back to back support.It had compact structure, rational layout, convenient assembly.By temperature rise and deformation tests,it is proved that the vertical milling head has reasonable temperature rise and small deformation under long time running condition.It has good accuracy retention.
