The polishing process after chamfering of the glass chamfering machine is characterized by the consumption of the polishing tool or the service life of the polishing tool. Although the nature of the glass, the grinding chamfering method, the rotational speed, the inherent quality of the glass itself will also affect the brightness of the glass polishing, the polishing rate, etc., but the basic choice is to choose the right polishing abrasive, so how to choose correctly Glass edge polishing tools are a very important issue.
First, the following factors should be considered when selecting and using polishing tools:
(1) Types of glass chamfering machines or edgers:
(2) Diamond grinding wheel used for rough grinding and fine grinding of glass edges:
(3) Requirements for the brightness of the glass edge:
Second, the type of glass edge polishing abrasives
There are many types of glass edge polishing tools. Due to the different manufacturers of glass edgers, the specifications and performance of the polishing tools used are different. At present, glass edge polishing tools do not have a uniform code and mark in China. In the abrasives industry, there is no specific product standard. Therefore, it is customary to follow the code of the glass edge polishing tool imported from abroad. Mark for selection and use. At the same time, domestic manufacturers of glass edge polishing tools also specify their own product codes and names according to the characteristics of the bonding agents used. Therefore, this paper is classified according to the current widespread use in China:
(1) 10s series polishing abrasives; (2) 9R series polishing abrasives; (3) BD series polishing abrasives; (4) BK series polishing abrasives; (5) polishing tools for glass car engraving machines; ) cerium oxide polishing abrasives; (7) wool felt polishing abrasives.
Polishing tools must be properly selected and used during the glass edge polishing process. First, determine the type of polishing tool to be used depending on the type and model of the glass edger 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 tool will be different. Therefore, in order to have a good polishing effect, it is necessary to use a good glass chamfering machine or edger.
Secondly, it is necessary to check whether the diamond roughing wheel and the finishing wheel are properly selected. Thirdly, according to the processing requirements of the glass, that is, the brightness requirement, the suitable polishing abrasives are selected to meet the processing requirements, thereby reducing the production cost and improving the production efficiency.
In the future, the grinding chamfer polishing specification should be observed. The polishing tool should be carefully inspected for cracking before installation. When installing, apply the flange with the diameter not less than one third of the diameter of the polishing tool. The polishing tool is used. The speed shall not exceed the speed of the safe working line; the polishing tool is not specially used for the end face work. It is forbidden to work with the end face of the grinding tool; the flow of the cooling water should be sufficient; the operation should be carried out according to the safe operation rules of the edger, and the glass is poured. The angle machine selects the appropriate working pressure of the head and the length of the glass and the traveling speed; the polishing abrasive should be protected from freezing and moisture during storage, and should not be in contact with alkali, otherwise it will affect the strength and polishing ability of the polishing tool. Therefore, in order to make the polishing abrasive tool have high efficiency, high precision, high quality and long life in the glass edge polishing, it is necessary to select and use the polishing abrasive tool reasonably and correctly.
