How to solve the problem of chipping after the glass has been ground?

1. Specific phenomena that cause problems

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

2. Causes and solutions

①The cause: the margin on the edge of the glass is too much or the conveying speed is too fast.

Solution: It is recommended that the glass margin be reduced by 1-2mm on one side, and the conveying speed of the belt be adjusted according to the thickness of the glass.

②The cause: The glass did not enter along the fixed side by the wheel, causing the unilateral grinding wheel to break the glass.

Solution: Readjust the fixed side and mobile side wheels.

③Cause: The angle of the diamond wheel is not correct (that is, the hind foot is ground).

Solution: The front foot of the grinding wheel can cut the lower edge of the glass along the violent edge, and the rear foot can cut the upper edge of the glass along the violent edge (the direction of the piece is the front, and the direction of the piece is the rear foot).

④Cause: There is a quality problem with the grinding wheel used, the cutting force is poor, and the sound of grinding the glass is too loud.In addition, the grinding ratio of the grinding head distribution has not been adjusted well.

Solution: Replace the grinding wheel and readjust the cutting ratio of the grinding wheel.

⑤The cause: The cooling water pipe is clogged, the grinding point is not reached, or the cooling water is not sufficient, resulting in insufficient water pressure to cool the grinding wheel.

Solution: Remove debris such as water pumps, sub-water pipes, grinding wheel water pipes, and glass powder deposits.

⑥Cause: The bearing of the grinding head motor is damaged or the gap between the bearings is too large, causing the grinding wheel to run radially and axially.

Solution: Replace damaged or excessively large motor bearings in time.

⑦Cause: The equipment has been used for a long time and the rough grinding base is loose, and there is vibration during the glass cutting process.

Solution: Strengthen the side of the motor base and tighten the screws to make the motor skateboard move forward and backward flexibly without vibration.

⑧Cause: Positioning malfunction broke the glass.

Solution: Debug the optical eye or stroke switch.

3. Preventive measures

① Before grinding the glass in each shift, raise the compression frame to a certain height, check whether the water pipe is at the right grinding point, turn on the water pump, and then see if the water pipe is smooth and the water pressure is high enough.

② Before batch processing of glass of different thicknesses, first use a piece of glass that is consistent with the thickness of the processed glass to confirm the cutting ratio of the grinding head.See if there is any chipping on the upper and lower edges.
