The present invention discloses a glass sheet chamfering machine which is improved such that it is suitable for a partial chamfering for a glass sheet. In the conventional glass sheet chamfering machine, and in carrying out a partial chamfering with this conventional machine, at the moment when one of the two glass sheet shape sensing rollers departs from the end point of the glass sheet, one of the rollers is turned to the direction of the straight edge, so that the chamfering wheel is also automatically turned. Consequently, the chamfering direction is deviated, with the result that the chamfering becomes impossible, or a defective chamfering is generated. The present invention eliminates such conventional disadvantage, by arranging that, even if one of the two rollers departs from the corner, the chamfering wheel is not turned. A horizontal supporting pad 20 mounts a glass sheet shape sensing device 19, and also mounts an adjusting key control plate 26 which is provided with an adjusting key guide slot 27, an adjusting key end portion 25a being pivoted through the adjusting key guide slot 27. Under the supporting pad 20, there is installed a pneumatic cylinder 28 for fixing an adjusting key 25. The pneumatic cylinder 28 is actuated through numeric controls, and the adjusting key 25 is controlled by the pneumatic cylinder 28, so that the glass sheet shape sensing device 19 should be fixed or released at exactly required positions. Thus the chamfering machine of the present invention carries out a partial chamfering automatically and continuously.
