Double Edgers - Pencil edge Flat Glass Technology > Copyright © BOTTERO S.p.A. Why choose the Bottero pencil edge double edgers?

Double Edgers - Pencil edge > Why choose them? Because of their high build quality Gemini and Mercury edgers have a sturdy structure thanks to the electro-welded steel frame and the abundant use of anti-corrosion materials such as stainless steel and technical polymers. Flat Glass Technology > Copyright © BOTTERO S.p.A. All parts in contact with water are made of stainless steel in order to prolong the working life of mechanical components. Thanks to automatic lubrication, all mechanical components work in optimal conditions, minimizing wear caused by friction. The spindles are equipped with...

Double Edgers - Pencil edge > Why choose them? During the work phase, the glass sheet conveyor system operates with high resistance belts built with the “closed loop" technology. The presence of springs guarantees the right pressure of the top belts on the glass depending on its thickness. Glass advancement is constantly monitored by an encoder connected to a specific circuit board which sends a series of signals to the electropneumatic system so that the polishing wheels only switch on as the sheet passes allowing the tools to be used to their best. The belt cleaning system removes any residues,...

Double Edgers - Pencil edge > Why choose them? Because they make sense The blowers installed at the bottom of the machine prevent contamination of the washing machine water by grinding residues, thus increasing washing quality. Flat Glass Technology > Copyright © BOTTERO S.p.A. The possibility of choosing different corner dubbing systems allows to control the quality of the corner according to different speed in order to meet any type of requirement. The opening and closing system of the mobile crosscut consists of trapezoidal screws designed to distribute strain at best and to reduce consumption...

Double Edgers - Pencil edge > Why choose them? Because they are easy to use On demand, the double edger can be equipped with water system tank and pump. The stainless steel tank is located at the end of the base, at a convenient position for cleaning. Flat Glass Technology > Copyright © BOTTERO S.p.A. The control panel is located in a comfortable position for the operator, near the loading zone. Operations are controlled by a PLC consisting of a membrane keyboard and an LCD display which makes entering and viewing data extremely easy. The amperometers which read the current absorbed by the grinding...

Double Edgers - Pencil edge > Why choose them? Because they offer something extra On demand, the double edger can be equipped with a corner dubbing system, consisting of two peripheral wheels (one on the each side) which process the four corners of the glass. There are three types of corner dubbing systems available: • Pneumatic system up to 8 m • Pneumatic system up to 12 m • Servo assisted system up to 20 m. In the HP versions, an inverter controls the motors of the diamond spindles, allowing their wheels to rotate up to 4200 rpm. Flat Glass Technology > Copyright © BOTTERO S.p.A.
