Numerical control photovoltaic printing table board visual positioning window polishing machine

The utility model discloses a numerical control photovoltaic printing table-board visual positioning window polishing machine, which belongs to the technical field of special visual machine part processing machines, and particularly structurally comprises a base, a gantry moving mechanism and a clamp. A working platform is arranged on the top of the base, and T-shaped grooves facilitating bolt fixing are formed in the working platform and used for fixing a clamp. A propelling device is arranged at the bottom of the base. The propelling device is in transmission connection with the gantry moving mechanism so as to push the gantry moving mechanism to move in the length direction of the base, and the gantry moving mechanism is provided with a polishing device so as to polish and grind the positioning window blank. Wherein the moving mechanism mainly drives the polishing device to move in the transverse direction or the vertical direction, and the positioning window blank is horizontally positioned through a clam
