Abstract
A scribing apparatus includes a horizontal table on which a glass plate is placed and fixed under vacuum suction; a feed screw and a Y-axis control motor 6 for moving the table along a pair of guide rails under scribe numerical control; a guide rail device body installed above the table along an X-axis direction; a carriage mounted on the guide rail device body so as to move in the X-axis direction while being guided; a feed screw and an X-axis control motor for moving the carriage in the X-axis direction under numerical control; and a scribe head installed on the carriage.
Claims4
A glass plate scribing method comprising the steps of:
- first scribe forming a dent at a scribe starting point at the time of a scribing start;
- and starting scribing from within said dent.
A glass plate scribing method comprising the steps of:
- first causing a cutter wheel to rotate or swing in a state in which said cutter wheel is brought into pressure contact with a glass plate at a scribe starting point at the time of a scribing start, to thereby scribe form a dent at the starting point;
- and subsequently starting scribing from within said dent.
A glass plate scribing method comprising the steps of:
- first causing a diamond scribe stylus provided separately from a cutter wheel to rotate or swing in a state in which said diamond scribe stylus is brought into pressure contact with a glass plate at a scribe starting point at the time of a scribing start, to thereby scribe form a dent;
- subsequently causing said cutter wheel to be brought into pressure contact with the glass plate at the dent formed;
- and starting scribing from within said dent.
A scribing apparatus comprising:
- a scribe head having a cutter wheel and adapted to scribe form a scribe line by rolling said cutter wheel in a state of being pressure contact with a glass plate;
- and a diamond stylus unit which has a diamond scribe stylus and causes said diamond scribe stylus to be brought into pressure contact with the glass plate to thereby scribe form a dent.
