The polishing process after glass chamfering is characterized by the consumption of polishing abrasives or the service life of polishing abrasives. Although the nature of the glass, the grinding and chamfering method, the rotation speed, and the inherent quality of the glass itself will also affect the brightness and polishing rate of the glass polishing, the fundamental thing is to choose the appropriate polishing abrasives, and how to choose them correctly. Glass edge polishing abrasives are a very important issue.

　　The selection and use of polishing tools should consider the following factors:

　　 (1) Types of glass chamfering machine or edging machine:

　　 (2) The situation of diamond grinding wheel used for rough grinding and fine grinding of glass edge:

　　 (3) Requirements for the brightness of the glass edge:

　　 2. Types of glass edge polishing tools

　　 There are many types of glass edge polishing abrasives. Because of the different manufacturers of glass edge grinding machines, the specifications and performance of the matching polishing abrasives are also different. At present, there is no uniform code and mark for glass edge polishing abrasive tools in China, and there is no specific product standard in the abrasives industry. Therefore, it is customary to follow the code and mark of glass edge polishing abrasive tools originally imported from abroad. To choose and use. At the same time, domestic glass edge polishing abrasive manufacturers have also designated their product codes and names according to the characteristics of the bonding agent they have adopted. Therefore, this article is classified according to the current domestic use:

　　 (1) 10s series polishing abrasive tools;

　　 (2) 9R series polishing abrasives;

　　 (3) BD series polishing abrasives;

　　 (4) BK series polishing abrasives;

　　 (5) Polishing abrasive tools for glass engraving machines;

　　 (6) Cerium oxide polishing abrasives;

　　 (7) Wool felt polishing abrasives.

　　 Three, the choice of glass polishing abrasives

　　The choice of glass polishing abrasives should be selected according to the type of glass chamfering machine or edging machine used, the processing method and the processing requirements. Several types of commonly used glass edging machines are described below.

　⊥荚啤（1）Straight-line edging machine

　　 Generally, 10S series or 9R series polishing tools are used. The 10S series polishing tools have better elasticity and polishing performance than the 9R series polishing tools. Therefore, most of the domestic glass deep processing manufacturers are using the 10S series polishing tools. There are two types of 10S series polishing tools and 9R series polishing tools. One is a polishing wheel for polishing the bottom edge of glass, and the other is a chamfering polishing wheel for polishing glass chamfering. As the hardness of 9R series polishing abrasives is harder than that of 10S series polishing abrasives, it has the characteristics of strong grinding force, high grinding efficiency and long service life. For some furniture glass and craft glass processing, high brightness is required, and cerium oxide polishing abrasives are often used.

　〖牙（2）Straight line beveling machine

　　 generally use 10S series polishing abrasives and wool felt polishing abrasives. The commonly used 10S series polishing abrasives are the specifications of the bottom wheel.

　∈蚺小（3）Single-arm shaped edging machine

　　 When polishing straight, round, duckbill and wavy edges of glass, BD series polishing abrasives and BK series polishing abrasives are generally used. Generally choose the appropriate thickness of the abrasive tool according to the thickness of the glass. When polishing the special-shaped beveled edge of glass, 10S series polishing abrasives and wool felt polishing abrasives are generally used. Wool felt polishing abrasives should also be used with cerium oxide polishing powder. Their selection method is the same as that of the straight beveling machine.

　　（4）Straight-line round edge machine

　　 BK series polishing abrasive tools and BD series polishing abrasive tools are usually used.

　〉坪（5）Glass car engraving machine

　　Usually, special polishing tools for glass engraving machines are used. Its specifications can be divided into two according to the type of machine.

　　 (6) Other chamfering machines, edging machines and special edging machines

　　In addition to the above glass edging machines, there are also some chamfering machines, small disc machines, portable edging machines, etc. The types of polishing abrasives they use are generally similar to the several polishing abrasives for edge grinding machines introduced above, but the specifications are different. When choosing, you should choose the corresponding polishing tool and size according to the shape, characteristics, brightness of the glass edge to be processed and the type of edging machine.

　　 Fourth, the use of glass polishing abrasives

　　 The correct and reasonable use of glass edge polishing abrasives can not only achieve satisfactory brightness, but also improve the polishing efficiency and the service life of polishing abrasives. Based on the characteristics of the main glass edge polishing abrasives introduced in the following, explain their respective methods of use.

  Fives. Concluding remarks

　　 In summary, the polishing tool must be correctly selected and used in the glass edge polishing process. First, determine the type of polishing tool to choose according to the type and model of the glass edging machine used. The same type of chamfering machine or edging machine, due to the difference in quality and accuracy, the polishing effect and service life of the polishing abrasive will be different. Therefore, if you want a good polishing effect, you must choose a good glass chamfering machine or edging machine. Secondly, it is necessary to check whether the diamond rough grinding wheel and the fine grinding wheel are suitable. Third, according to the glass processing requirements, that is, the brightness requirements, choose and use suitable polishing abrasives to meet the processing requirements, reduce production costs, and improve production efficiency. Finally, it is necessary to comply with the grinding chamfer polishing specifications, and the polishing abrasive should be carefully checked for cracks before installation; when installing, use a flange with a diameter not less than one-third of the polishing abrasive diameter to tighten; the use speed of the polishing abrasive The safe working line speed must not be exceeded; polishing abrasive tools that are not specifically used for end-face work are prohibited from working with the end face of the abrasive tool; the flow of cooling water must be sufficient; the operation must be carried out in accordance with the safe operating regulations of the edge grinding machine and the appropriate The working pressure of the head and the glass and the speed of travel are long; during storage, the polishing abrasive should be protected from freezing and damp, and it is not suitable to contact with alkalis, otherwise it will affect the strength and polishing ability of the polishing abrasive.

　　 Therefore, in order to make polishing abrasives in glass edge polishing with high efficiency, high precision, high quality and long life, it is necessary to select and use polishing abrasives reasonably and correctly.
