## Abstract

A glass-plate working machine 1 is arranged such that while a cutting head 9 for forming a cut line on a glass plate 5 and a grinding head 10 for grinding a peripheral edge of the glass plate 5 bend-broken along the cut line are being moved simultaneously in parallel under numerical control, the cutting head 9 and the grinding head 10 respectively having angle control motors 46 and 49 are synchronously subjected to angular control about axes 39 perpendicular to the surface of the glass plate 5, and the cutting head 9 and the grinding head 10 are moved such that the orientation of a cutter wheel 52 is adjusted to a processing line, and the press contacting direction of a grinding wheel 64 of the grinding head 10 is kept in a normal direction with respect to a processing line of an edge of the glass plate 5.

## Claims

### Claim 1

A glass-plate working machine comprising:
a cutting section including a cutting head with a cutter wheel and a cutting table for supporting a glass plate and
a grinding section including a grinding head with a grinding wheel and a grinding table for holding the glass plate, said cutting section and said grinding section being adapted to depict an identical contour moving locus simultaneously in parallel, while said cutting head and said grinding head being adapted to be angularly controlled about an axis perpendicular to an orthogonal plane coordinate system,
wherein each of said cutting head and grinding head has an angle control motor so as to synchronously operate angular control of said cutting head and angular control of said grinding head,
wherein each of said cutting head and said grinding head is laterally mounted to a lower end portion of a respective hollow rotating shaft which is rotatably attached to a moving base.

### Claim 2 (depends on 1)

The glass-plate working machine according to claim 1, wherein said moving base is adopted to move as one axis of a plane coordinate movement, said respective hollow rotating shaft is perpendicular to a plane of plane coordinate movement, and said angle control motor is laterally coupled to an upper end portion of said respective rotating shaft by means of transmitting means, said rotating shaft having a hollow portion extending through from an upper end to a lower end thereof.
