This PLC controlled glass straight line bevelling machine is designed to finish rough grinding, fine grinding, hemline grinding, as well as polishing treatment for flat glass, and it includes three models which are RBL261B, RBL361B and RBL371B.

Features
1. A coarse pitch chain is adopted to transport the glass, and the steady delivering performance contributes to the precise result.
2. The rear transferring board is equipped with an automatic cleaning device to keep it clean all the time.
3. Thanks to the manual lubrication system, this glass straight line bevelling machine is able to work under good lubrication conditions.
4. With the help of PLC control system, both automatic control and manual control are realized. On the human-machine interface, users can set relevant parameters, such as bevel width, original glass thickness, remaining glass thickness after processing, etc.
5. By lifting and descending the back guide rail, the fall between front and back guide rails is adjusted. As a result, larger glass panels are applicable, and the processing specification is also enlarged.
6. Because of the high rigidity, stable performance, high yield rate as well as superb precision of lifting and descending, this glass straight line bevelling machine fits for batch production of glass mosaic.

Major Components

Item	Descriptions
Machine and frame	The base, upright column, cross beam, grinding head, front and back guide rails are all constructed by welding high quality steel plates, and then high temperature annealing treatment is applied for a long time. Finally, rough machining and fine machining are carried out. Thus, these parts possess large loading capacity which makes them be able to provide stable performance.
Front and back platens	These platens are made of 40Cr steel, and the friction surfaces receive fine grinding after high frequency quenching treatment, making them more durable.
Grinding head 9# and 10#	They are pneumatically polished by the high precision linear slide rail to offer better result.
Motor for grinding head	Shanghai ABB motor or Shanghai CDQC motor is equipped, and these products can provide stable performance with low failure rate.
Water pump	Hunan Shanqing brand
Variable frequency motor	The main transmission uses a variable frequency motor that is supplied by Zhengjiang Xinling Motor Co., Ltd. (former Huangyan Motor Factory), and a big torque reducer is also applied. Meanwhile, the linkage between front and back guide rails is achieved with the help of a big modulus gear box, realizing more stable transmission when grinding bevel edge and thick glass.
Pendulum seat	It adopts screw rod rear support structure to improve grinding rigidity.
Screw rod for front guide rail	The nut is installed at the side face of upright column to facilitate maintenance jorb.
Output delivery	The guide rail is equipped with guiding devices for small glass panels to protect the glass from being stuck to back board during grinding process.
Transmission worm gear box	Zhujiang brand
Bearing	HRE: Harbin Ruiha Beaing Co., Ltd.
Glass support shelf	It is made of aluminum alloy.
Timing belt	A famous Sino-American joint venture: Yongli
Transducer	Emerson, USA
Rotary switch and emergency stop	These parts are supplied by Jiangyin Changjiang Electric Appliance Co., Ltd. and Guangzhou Benlee Industrial Switch Manufacture Co., Ltd.
Photoelectric switch and intermediate relay	Omron, Japan
PLC	Delta, Taiwan
Human-machine interface	Hitech, Taiwan
Rotary encoder	Autonics, Korea
Transformer, contactor, and low voltage circuit breaker	Juche Electric Appliances Co., Ltd., and CHINT Electronics Co., Ltd.
