CYLINDRICAL & INTERNAL EDGING MACHINE is suitable for processing edges of cylindrical & internal or the molded glass edges with 150-500mm, the cylindrical can be edged as flat, circular and duck mouth shapes. The processed glass is adsorbed onto a vacuum sucker. A mechanical stepless speed regulator is adopted to make the curbing work. The speed can be regulated when the curbing work and can be slewed steadily. Either the machine can make use of the pneumatic mechanism for semi-automatic grinding. When grinding glass with different thickness, the wheel head can be raised or lowered fast with the air cylinder to change its position or change the heads. The rough grinding, fine grinding and the polishing can be done by changing wheels.
