The lift of the rocker arm is driven by the motor on the top of the column.It is driven by the screw and nut pair to realize the lifting of the rocker arm. The lifting nut is equipped with a safety nut,in order to ensure that the rocker arm cannot fall down suddenly.The rocker arm clamping is realized by hydraulically driving the diamond block.After clamping, the diamond block is self-locking. After the lifting or lowering of the rocker arm is completed, the rocker arm is automatically clamped, which is controlled by an electrical switch mounted on the cylinder base.Mechanical change speeds in head stock, powerful milling.Table with an extra supporting column, big load, high accuracy.It can mill any angle surface through front half-sphere by swiveling milling head
