The hemisphere machining apparatus of claim 6, wherein: the rotating device comprises a base, a rack (12) which is rotatably arranged on the base and is used for installing a hemispherical supporting seat (11), a transmission shaft (13) which is rotatably arranged on the rack (12) and one end of which is connected with the hemispherical supporting seat (11), a driven gear (14) which is arranged at the other end of the transmission shaft (13) and is coaxially arranged, a main gear (15) which is meshed with the driven gear (14), and a rotary driving motor (16) which is used for driving the main gear (15) to rotate; the output shaft of the rotary driving motor (16) is coaxially arranged with the main gear (15).

8. The hemisphere machining apparatus of claim 6, wherein: the X-axis driving mechanism (5) is used for driving the Y-axis lifting mechanism (3) and the Z-axis driving mechanism (2) to move along the X-axis direction.

9. A hemisphere processing apparatus as claimed in claim 8, wherein: the X-axis driving mechanism (5) comprises an X-direction supporting seat (51) arranged along the X-axis direction and an X-axis driving device used for driving the cross beam (22) to slide along the X-direction supporting seat (51); the cross beam (22) is provided with an X-direction groove (221) matched with the X-direction supporting seat (51); the X-axis driving device comprises an X-direction rack (54) arranged along the X-axis direction and mounted on the side surface of the X-direction supporting seat (51), an X gear (53) meshed with the X-direction rack (54), and an X-axis driving motor (52) with an output shaft and the X gear (53) coaxially arranged and in transmission connection.

10. A hemisphere processing apparatus as claimed in claim 9, wherein: the X-axis driving device further comprises X-direction guide rails (56) which are arranged on two sides of the X-direction supporting seat (51) and arranged along the X-axis direction, and X-direction guide rail sliding blocks (55) which are arranged on two sides of the X-direction groove (221) and matched with the X-direction guide rails (56) for use.
