The machine is suitable for edge and corner grinding of plate glass of different size and thickness,finishing coarse grinding and polishing at one time.The flat surface after polishing is close to bright and clean degree of glass sting different processing thickness(able to refer to data display instrument on front-axle beam),former chamfering grinding head can move simultaneously along with the front-axle beam.It possesses the advantages of advances structure,high working precision,easy operation and capacity of continuous processing for the same thickness,definitely being necessary equipment for glass deep processing.
