The invention discloses a simple and efficient chamfering machine oriented to mass production of glass, comprising four same hosts, two sets of cross slipways, a worktable, a stand and a glass transport mechanism, wherein the four hosts are connected in parallel two by two and are respectively correspondingly arranged on the stand back and forth, a dovetailed way is arranged at the support bottomof each host and is connected with the stand by the cross slipway, and the two hosts connected in parallel are arranged on the same cross slipway; the worktable is arranged on the stand, the glass transport mechanism is supported by the stand and is arranged below the worktable, glass transported by the glass transport mechanism is chamfered with two angles at the same side by two hosts at the front half part of the worktable, and two hosts at the back half part chamfer two angles at the other side. The invention has the advantages that the hosts greatly simplify the processing structure and enhance the machining precision, the sideways adopts manual adjustment, and a graduated scale is used for calibration, thereby simplifying the structure, reducing the cost, enhancing the precision andbeing suitable for mass production.
