Electronic straight-line edging machines for the processing of flat edge with arris. 

All the wheels are fitted on spindles in order to allow an homogeneity of rotation and to avoid vibrations. The spindle has a strong frame, the rotating shaft is assembled on ball bearings in order to guarantee a perfect alignment. The mechanical seal, an essential element of the spindle, is obtained thanks to the application of diaphragms. The conveyors slide on guides of hardened and rectified steel. In order to avoid the wheels wear and tear, a centralized lubrication system is fitted. The conveyor is composed by pads, made of a special material, which are mounted on precision chains. Pneumatic glass clamping system. The polishing wheels intervention is automatic because it is controlled by a PLC. All the wheels are cooled by coolant pumped from the coolant tank under pressure. The arris wheels automatically adjust with the change of the glass sheet thickness.
