At the test site, the technicians started the joint production line. After the original glass was processed by the high-precision edge grinding machine, it was seamlessly connected to the high-pressure air cleaning machine through the intelligent conveyor belt, without any manual intervention.



1.Pioneered positioning mode: Non touch glass after positioning probe switch. Longer life, more convenient operation and maintenance;

2.Patent structure, processing glass thickness 3~12mm;

3.All imported servo electronic, to make the equipment more stable and reliable;

4.Transmission using a toothed chain transmission, more stable, more static;

5.Opening & Closing using rack drive, speed up to 40 meters per minute, more accurate, more durable;

6.Hemline grinding function.



Glass Automatic Four Sides Edger is designed for glass chamfering with features of economy, efficiency and automatic identification of glass size and thickness. This machine is suitable for processing the construction glass, insulating glass of window and door and other different size flat glass with a large quantity. Being connected with other machines, the production efficiency can be improved deeply.



1.Adopt the servo-driven, annular timing belt and rubber roller for conveying and polyurethane wheel for press which ensures the stable glass transmission, accurate positioning and excellent grinding performance.

2.The automatic opening and closing mechanism of grinding motor and lateral pressing wheel are adopted the gear reducer and servo driver. Assembling with the ball screw rod, liner guide rail, pinion and rack, the mechanism can be accuracy.

3.The motor rotation system adopts the gear reducer and servo driver that make it position precisely.

4.Adopt limit switch probe positioning instead of touch glass that avoid the distress of parameters resetting due to the replacement of probe. This novel design greatly improves the life of the limit switch probe and makes the operation and maintenance more convenient.

5.Adopt human interface and PLC control system, easy operate.



Highly intelligent high-speed four-side grinding is widely used in the fine edge grinding of door and window glass. For developed countries, they need it very much, and for developing countries, which do not have high requirements for edge grinding quality, it will also be completely suitable for them. Use seaming machine to grind the edge to achieve the requirements of tempered edge grinding.

Recently, the fully intelligent glass processing production line independently developed by SANKEN Glass Machinery (hereinafter referred to as "SANKEN") was officially put into operation at the customer production base. The production line integrates automation, digitization and intelligence, and realizes continuous operation of the entire process from raw sheet cutting, edging, tempering to finished product sorting, helping customers improve production efficiency by more than 30%, and the yield rate reaches 98%, marking a key step for the glass deep processing industry towards next stage.
