I. Specific Phenomena of the Problem:

① Violence at the upper edge;② Violence at the lower edge;③ Grinding wheel shattering the glass

II. Causes and Solutions

① Cause: Excessive glass edge allowance or excessively fast conveying speed.Solution: It is recommended to reduce the glass edge distance on one side by 1-2mm and adjust the belt conveying speed according to the glass thickness.

② Cause: The glass did not enter along the fixed side of the grinding wheel, causing the single-sided grinding wheel to shatter the glass.Solution: Re-adjust the fixed-side wheel and the moving-side wheel.

③ Cause: Incorrect angle of the diamond grinding wheel (i.e., back-foot grinding).Solution: The front foot of the grinding wheel cuts past the lower edge of the glass, and the back foot cuts past the upper edge of the glass (the film feeding direction is the front foot, and the film output direction is the back foot).

④ Cause: The grinding wheel used has quality problems, poor cutting force, and excessive grinding noise.In addition, the grinding ratio of the grinding head distribution has not been adjusted properly.Solution: Replace the grinding wheel and re-adjust the cutting ratio of the grinding wheel.

⑤ Cause: Clogging of the cooling water pipe, misalignment of the grinding point, or insufficient cooling water, resulting in insufficient water pressure and inability to cool the grinding wheel.Solution: Remove debris and glass powder from the water pump, water distribution pipe, and grinding wheel water pipe.

⑥ Cause: Damage to the grinding head motor bearing or excessive bearing clearance, causing radial and axial runout of the grinding wheel.Solution: Replace the damaged or excessively worn motor bearings in time.

⑦ Cause: Long-term loosening of the equipment's rough grinding base, causing vibration during glass cutting.Solution: Strengthen the side of the motor base, tighten the screws, making the motor slide smoothly back and forth without vibration.

⑧ Cause: Misoperation of positioning shattered the glass
Solution: Adjust the photoelectric tube or limit switch.

III. Preventive Measures

① Before grinding glass each shift, raise the pressure frame to a certain height, check if the water pipe is at the correct grinding point, turn on the water pump to check if the water pipe is unobstructed, and if the water pressure is sufficient.

② Before batch processing glass of different thicknesses, first use a piece of glass with the same thickness as the glass to be processed to confirm the cutting ratio of the grinding head.Check for any notches on the upper and lower edges.

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.
