(Summary description)
1. The specific phenomenon of the problem:   

①The upper edge of the edge is violent; ②The lower edge of the edge is violent; ③The grinding wheel breaks the glass

2. Causes and solutions

①Causes: Too much margin on the edge of the glass or too fast conveying speed. Solution: It is recommended to reduce the glass margin by 1-2mm on one side, and adjust the conveying speed of the belt according to the thickness of the glass.

②Cause: The glass did not enter along the fixed side by the wheel, which caused the unilateral grinding wheel to break the glass. Workaround: Readjust the fixed side and moving side wheels.

③Cause: The angle of the diamond wheel is not correct (ie, the rear foot is ground). Solution: The front foot of the grinding wheel excessively cuts the lower edge of the glass, and the rear foot cuts the upper edge of the glass (with the film feeding direction as the front, and the film output direction as the rear foot).

④Cause: The grinding wheel used has quality problems, poor cutting force, and the sound of grinding glass is too loud. In addition, the grinding ratio of the grinding head distribution is not adjusted well. Solution: Replace the grinding wheel and re-adjust the cutting ratio of the grinding wheel.

⑤Causes: The cooling water pipe is blocked, the grinding point is not aligned, or the cooling water is not enough, resulting in insufficient water pressure, and the grinding wheel cannot be cooled. Solution: Remove sundries and glass powder from the water pump, water distribution pipe, grinding wheel water pipe, etc.

⑥Causes: The bearing of the grinding head motor is damaged or the clearance of the bearing is too large, which causes the radial runout and axial jump of the grinding wheel. Solution: Replace the damaged or excessively large motor bearing in time.

⑦Cause: The rough grinding base of the equipment is loose for a long time, and vibration occurs during the glass cutting process. Solution: Reinforce the side of the motor base and fasten the screws to make the motor slide forward and backward flexibly without vibration.

⑧Causes:Positioning misoperation to break the glass
Solution: adjust the photocell or travel switch.

3. Preventive measures

① Before grinding the glass in each shift, raise the pressing frame to a certain height, check whether the water pipe is in the correct grinding point, turn on the water pump and check whether the water pipe is smooth and the water pressure is large enough.

②Before batch processing of glass of different thicknesses, first confirm the cutting ratio of the grinding head with a piece of glass whose thickness is the same as that of the processed glass. Check to see if the upper and lower edges are chipped or not.

How should a glass edger be used?

With the development of science and technology, people can not only give full play to the natural advantages of glass, but also adjust its performance to make up for its defects. Let's take a look at how to use a glass edging machine and what processes are needed to make glass. 1. Matters needing attention when using the glass linear edging machine: The working method of the straight edge grinding machine (straight edge machine, round edge machine, bevel edge machine) is to clamp the glass through the front and rear platens and drive its linear motion for grinding. Two points must be paid attention to in use: ① The front and rear platens are connected to the glass. The joint surface of the guide rail should be lubricated frequently, otherwise the normal service life of the machine will be affected due to the premature wear of the front and rear pressure plates and the working surface of the guide rail. Although some models have an automatic lubrication device, it is necessary to check whether the lubrication pipeline is smooth; ② When clamping the glass, the clamping force should be appropriate. Too loose will affect the grinding quality. If it is too tight, the load of the machine will increase, and the phenomenon of shaking and crawling will easily occur. It is easy to break the glass when grinding thin glass. The large glass is clamped on the machine for testing, that is, the glass is clamped in the middle of the machine, and the glass is moved with both hands when the machine is stopped, and the clamping force is adjusted to just when the hands cannot be moved. 2. Precautions when using the glass special-shaped edging machine ① Whether the height of the suction cups of the special-shaped machine workbench is consistent has a great influence on the grinding effect. During assembly, the manufacturer has carried out self-grinding on the five sets of suction cup seats, and selected suction cup glue with the same thickness to keep the height of each suction cup consistent. Therefore, generally Do not disassemble or assemble the suction cups under any circumstance. If the suction cup glue is damaged, choose the one with the same thickness to replace. ②After the vacuum pump of the special-shaped machine is used for a period of time, the vacuum degree will decrease (that is, the suction force will drop) due to water inflow and other reasons. , So pay attention to checking and troubleshooting, otherwise, the machine will work under the condition of insufficient suction, which will affect the grinding quality on the one hand, and it will also be prone to safety accidents on the other hand. 3. Precautions when using the bilateral edger ①The double-sided edging machine is a relatively inferior edging machine. It is recommended to fix two or three people to operate it to ensure correct operation. ②When there is an error or failure in the double-sided grinding program, it is recommended to ask the original manufacturer to send someone to repair and debug it. Under normal circumstances, do not dismantle and repair, so as not to mess up the program and cause production stoppage. 4. Precautions for the use of the moulding machine ①The mold of the touch machine has a great influence on the grinding accuracy. The working surface of the mold must be accurate in shape and size, and the finish must be high. If the special-shaped mold is based on the template, the transition must be smooth. Be sure to keep the suction cup working surface level, otherwise it will affect the grinding quality. In addition to the edging machines introduced above, there are also some edging machines with simple structure and single purpose, such as chamfering machines, small wafer machines, polishing machines, etc. In addition, there are also some special edging machines for processing certain products. , such as car rearview mirror edger, washbasin edger, etc.

How to maintain the glass edger?

1. Choose the right machine: 　　There are more and more types and specifications of glass deep processing machines, and the functions of some machines will overlap. People have doubts, the functions are the same, why the price is so different, and even more functions. At this time, you have to think about the specifications, what kind of work you want to do with it, and what kind of machine you want to use to achieve the processing effect you need. Some research must be done before purchasing to avoid unnecessary losses. 　　 2. Try to save money as much as possible: 　　the current price of the machine has dropped compared to the past, but the price of the same type of machine from various manufacturers sometimes differs by tens of thousands. There are many factors that cause this price gap, such as: material selection, craftsmanship, after-sales, profit margins Wait, you must ask carefully at this time, it may not be affordable, and high prices may not necessarily mean high quality. 　　 3. Reliable quality: 　　There are many customers who have such a misunderstanding that the quality of the machines of big factories is better than that of small factories. What I want to say to you is: this is true, but it is not entirely true. Compared with small factories, large factories are more mature in overall technology, but large factories involve a wider range of production. Small factories can only be limited to a small area because of their small size. There is a word called "small and specialized". The quality of the machine cannot be judged entirely by the size of the manufacturer. 　　 4.after-sales service: 　　At present, there are nearly 100 domestic edge grinding machine manufacturers. When purchasing a machine, customers should first choose a manufacturer with high reputation and good after-sales service. It is more reliable to use. Even if there are some technical problems in use, these manufacturers will help You solved it in time. Generally, it is free of charge except for wearing parts during the warranty period, and the cost will be charged appropriately after the warranty period. If you are not satisfied with the quality of the purchased equipment, you can also replace it. If you agree with the above four points, then please continue to read, I believe that the content I have described below will definitely be helpful to your purchase. 　　 　　First, how should you save money: At present, the overall profit margin of the machine price is not very large. If you want to reduce the purchase cost of the machine through price reduction, it is difficult to achieve this. Because manufacturers also have to survive, the concessions that can be made are not large. Some manufacturers clearly give you a lot of benefits, but they actually capture the psychology of customers. They turn around and make a fuss about the machine, either cutting corners on the machine, or asking you to buy other products that also have this function but the price Cheap machines, and often this kind of machine is either short-lived or limited in processing capacity. When you react too late, the gains will outweigh the losses in the end. Therefore, if you want to really save money, then it is recommended that you must learn more about the performance of the machine before purchasing it. In this way, you can avoid detours and losses. 　　 　　Second, what kind of machine is suitable to choose: How to choose a suitable model among the various types of glass machinery and equipment? It is a common concern of glass processing users. Here are some suggestions based on the work experience and experience of glass processing equipment. 　　 　　The first is to position yourself. The so-called positioning is to determine what you want to do. It is necessary to clarify the nature and use of the glass being processed. Then you can use this as a requirement to find the right type of machine. Finally, the specific model of the machine is determined according to the specifications of the glass. The following is an example of a glass edging machine : 　　 　　to choose an edging machine, you must first understand the types and characteristics of the edging machine. There are many types of edging machines, and how to choose should be selected according to the characteristics of the processed products and the scale of production. Taking the edger as an example, the edger that can grind the edge includes a special-shaped machine, a linear edger, a die-cutting machine, a linear double-sided edger, etc. How to choose must be combined with the requirements of processed products. If the product designed to be processed is round, oval or otherFor special-shaped glass, you can only choose a special-shaped machine or a molding machine (because the straight edge rounding machine cannot grind round or special-shaped workpieces). If there are many types of products designed and processed and the batch is small, it is more appropriate to choose a special-shaped machine, because the s
