Our glass straight line double edging machine mainly contains four models which are RBL2025B, RBL2042B, RBL2025BL, and RBL2042BL.

RBL2025B and RBL2042B are our newly developed products, and they show the advantages of high efficiency, high precision, reasonable price, safe and reliable running, etc. They are applied to grind flat glass and common laminated glass with different specifications, and they are very suitable for batch production and scale production.

As for the other two models, namely RBL2025BL and RBL2042BL, they also fit for batch production and scale production, and they are used to process flat glass, common laminated glass, and low-E glass.

Main Components
1. The opening and closing operations of this glass double edging machine are achieved with the help of ball screw and straight line guide rail. The opening and closing are automatically controlled with excellent repositioning precision.
2. The grinding wheel adopts double V type guide rail, and it offers stable and precise performance with small vibration.
3. The polishing process adopts semi-automatic compensation.
4. For chamfering treatment, the ball screw and linear guide are applied to achieve automatic upward and downward motions with precise positioning and simple operation.
5. The cleat bracket is designed to move in the vertical direction automatically, and the movement range can reach up to 120mm. In addition, it is very convenient to change the grinding wheel.
6. The main transmission drive takes advantage of mechanical frequency conversion technology to control the speed, and it is upper placed which is a novel design. So, the replacement and maintenance for the belt can be finished easily.
7. Our glass straight line double edging machine uses annular synchronous belt and pneumatic positioning device to transport the glass, realizing steady delivery and precise positioning.
8. Due to the human-machine interface and the high-end PLC control system, our product shows high automation degree, and the operation is quite simple.
