That is, the cutting head 7 and the polishing head 8 share the X-axis and Y-axis of the orthogonal coordinate system.

The glass plate processing machine according to the present invention causes the cutting head 7 and the polishing head 8 to move in the X-axis direction, which is the left and right direction when viewed from the front of the glass plate processing machine, and the work table 19 that holds the glass plate is placed on the work table 19. Movement is performed in the Y-axis direction, which is the front-rear direction when viewed from the front of the glass plate processing machine.

3 and 23 are engaged with slide rails 24 and 24. Through such engagement, the table 19 is supported by the slide rails 24 and 24. Since these slide rails 24 and 24 are laid in parallel along the Y-axis direction of the machine base 10, the table 19 is guided to move in the Y-axis direction. The table 19 is driven in the Y-axis direction by two sets of feed screws 25 and 25 provided along the slide rails 24 and 24.

Therefore, the cutting head 7 and the polishing head 8 are rotationally controlled by the rotation of the shaft 31 around a vertical axis perpendicular to the orthogonal plane coordinate axes formed by the XY axes. The rotation of the cutting head 7 and the polishing head 8 is driven by bevel gears 32 and 32 attached to the shafts 31 and 31 of each bearing device 30, respectively, and these bevel gears 32.

This is performed by a line shaft 33 to which the bevel gears 32, 32 are attached at both ends, respectively, and a Z-axis control motor 34 that drives the line shaft 33.

The piston rod 41 is moved up and down in the Z-axis direction along the direction of arrow 390, and when cutting glass, descends to apply cutting pressure to the cutter wheel 351.

The position of the cutter wheel 351 can be adjusted by moving the setting slide 37 and the cross slide 38, that is, by moving the respective adjustment screws 317, 381, so that the position of the cutter wheel 351 is adjusted to the axis of rotation of the cutting head 7, that is, the axis 391 of the shaft 31 of the bearing device 30. In addition, the position of the cutter wheel 35 can be shifted from the position of the axis 391, thereby making it possible to finely adjust the cutting locus. In other words, the cutting miracle can be expanded or contracted.

In this way, when the polishing point P on the peripheral end of the polishing wheel 47 coincides with the axis 392 of the shaft 31, the polishing point P on the peripheral end of the polishing foil 47 and the cutter wheel 35 of the cutting head 7 are draw almost identical movement trajectories. Therefore, the polishing head 8 adjusts with the screw 441 of the cut adjustment slide 44 to move the polishing point P on the peripheral end of the polishing wheel 47 forward from the axis of the shaft 31 (gives the amount of cut), and sets a movement trajectory. The polished finish size is adjusted by reducing the size somewhat.
