AUTOMATIC VERTICAL EDGER
★ OPTIMISED FOR SPECIAL GLASS ★ DEVELOPED WITH LEADING GLASSWORKS ★ HIGH QUALITY STANDARDS
The EM edging machine is designed for processing the edges of float and laminated glass sheets. It can perform edge arrissing, rough edge grinding and edge polishing. In addition to featuring selflearning functionality the machine is able to square the glass to the final required dimensions, it can be therefore be used in double glazing, tempering and or grinding lines. The machine is a solid structure featuring Forel’s innovative mono-block construction reflecting the philosophy and culture for quality build. This feature guarantees extreme accuracy, performance and capacity especially considering weight per linear metre. The operating head is equipped with an electric spindle with power of 9.2 kW, rotation speed of 4,500 rpm and a 200 mm diameter grinding wheel ensuring high speed machining and material removal rates. During machining, the glass is handled by a carriage equipped with suction cups that have a strength capacity of up to 200 kg/m firmly secure the glass in position. An automated suction cup drying system, along with its precise movement, ensures a perfect adhesion of the suction cups to the glass. The operating head is equipped with a patented system that permits connection of securing devices close to the area of grinding. This ensures perfect centering with the grinding tool relative to the glass edge and the absence of vibration during machining. The grinding tool and glass are and remain perfectly aligned throughout the process, regardless of the glass length. The grinder operates in self-learning mode on rectangular glass panes, and on shaped glass it uses an on-board editor or imported CAD files. The dynamic self-learning system detects the glass profile via a patented feeler that locally checks the position of the glass edge with respect to the tools during machining. In order to limit tool changes and facilitate machining, the spindle cone allows mounting a “grinding tool set” of up to 80 mm total thickness. The machine is equipped with a system that monitors consumption, approach and grinding tool speed (pre-setting), and automatically adjusts the latter’s peripheral speed. An automatic redressing system for the polishing wheel is included. By simply creating the settings in the PLC, different types of machining can be performed in alternating sequences: edge polishing - rough edge grinding - arrissing. The machine is equipped with a special diagnostic system and a remote connection assistance programme. The machine includes dedicated software that ensures excellent polishing, even on difficult areas like corners and narrow radius.
