Supporting movable device for chip discharging machine of precision CNC numerically-controlled machine tool

The invention discloses a supporting movable device for a chip discharging machine of a precision CNC numerically-controlled machine tool. The supporting movable device comprises a supporting plate used for supporting the chip discharging machine, and further comprises a movable vehicle. The supporting plate is arranged on the movable vehicle. The movable vehicle is further provided with a pneumatic jacking-pushing device. The pneumatic jacking-pushing device drives the supporting plate to rise or fall. According to the supporting movable device for the chip discharging machine of the precision CNC numerically-controlled machine tool, the supporting plate arranged on the movable vehicle can be directly arranged under the chip discharging machine in an inserted mode; the supporting plate isdriven through the pneumatic jacking-pushing device to rise or fall, and then the chip discharging machine is lifted or put down; and by means of the supporting movable device, the effect that movingof the chip discharging m
