In order to make column and brill mill the horizontal displacement of unit head energy, the utility model also comprises the displacement mechanism that contains screw mandrel, hold-down support and stop collar, hold-down support is fixed in a side of moving-coil, screw mandrel passes the through hole on the hold-down support, its nut inner and on the column is meshed, be provided with the stop collar that is placed on the screw mandrel in the hold-down support both sides, and stop collar is connected by pin with screw mandrel.Like this, leading screw can only rotate and can not rectilinear motion, and makes column move as horizontal linear.

During work, at first the chassis fixed block is welded in spherome surface, and the chassis fixed block is on the same horizontal plane, and regulates the horizontal level that column and brill mill unit head by displacement mechanism, relative to cutter with required tapping.Start cutting blade motor, make the cutter rotation, restart lifting motor, it is descending to drive cutter, spheroid is cut, after extremely certain degree of depth to be cut, start turning motor then, make cutter do the revolution cutting, behind revolution cutting one circle, make cutter descending again, so cycle operation, perforate required on spheroid is processed into.

The beneficial effects of the utility model are: reduce labor strength, increase work efficiency and crudy, reduced production cost.
