How to solve the problem of chipping glass after grinding?

When the glass grinding process is completed with chipped edges, this usually indicates some deficiencies in the process or improper equipment adjustment. This problem can be analysed and solved from several angles. Below are a few possible causes and the corresponding solutions:

1. Adjust the edge margin of the glass

● Cause of the problem: If the edge allowance of the glass entering the grinding equipment is too large, it will easily cause excessive pressure on the grinding wheel, which will lead to edge chipping.

● Solution: It is recommended to reduce the glass margin by 1-2 mm on one side, which will help reduce the cutting pressure of the grinding wheel on the glass, thus avoiding the occurrence of edge chipping.

 

2. Optimise the conveying speed of the grinding machine

Cause of the problem: Too fast conveying speed may lead to insufficient grinding force, making the edge of the glass chipped due to uneven force.

Solution: Adjust the conveyor speed of the belt according to the thickness of the glass to ensure that the grinding speed matches the hardness and brittleness of the glass, so as to avoid chipping caused by improper speed.

 

3. Adjust the angle and configuration of the grinding wheel.

● Problem cause: The angle of the grinding wheel is not correct or the grinding ratio of the grinding head distribution is not adjusted properly, which will lead to uneven grinding strength and thus cause edge chipping.

● Solution: Check and adjust the angle of the grinding wheel to ensure that the front foot of the wheel cuts the lower edge of the glass and the rear foot cuts the upper edge of the glass. At the same time, readjust the grinding ratio of the grinding head distribution to ensure that the cutting force is evenly distributed on the glass edge.

 

4. Replace the grinding wheel and adjust the equipment

Cause of the problem: The use of poor quality grinding wheels may lead to poor cutting force and increase the risk of chipping during glass grinding.

● Solution: Replace the grinding wheel with a new, better quality wheel to ensure that it has sufficient cutting power and durability. Also, regularly maintain and check the stability of the grinding wheel installation, and make timely adjustments or replacements to ensure equipment performance.

 

5. Improve the cooling system

● Cause of the problem: Inadequate cooling causes the temperature of the grinding wheel and glass to rise during the grinding process, increasing the risk of glass breakage.

● Solution: Check whether the cooling water pipe is blocked, clean debris and glass powder deposits in the water pump, manifold and grinding wheel hose, and ensure that the cooling system is unobstructed and the water pressure is sufficient to adequately cool the grinding wheel.

 

6. Operation and maintenance of equipment

● Cause of Problem: Improper operation and poor condition of equipment can lead to unsatisfactory grinding results, including chipping.

● Solution: Ensure that operators are properly trained on grinding equipment and its maintenance. Maintain the quality and performance of the grinding equipment, and carry out regular maintenance and overhauling, especially of the control system and drive train.

 

In addition, in addition to addressing the chipping problem directly, the following areas need to be addressed to prevent similar problems that may occur in the future:

● Material selection: Selection of glass materials with qualified quality, uniform hardness and no internal defects is essential to minimise problems during edge grinding.

● Process optimisation: Reasonable selection of the grinding process and grinding wheel, control of the grinding speed and pressure to ensure the stability and cooling effect of the grinding process.

 

In summary, to solve the chipping problem after glass grinding requires comprehensive consideration of a number of factors, such as material selection, equipment adjustment, process optimisation and operation specifications. Through the implementation of the above measures, not only can effectively solve the current chipping problem, but also improve the overall grinding efficiency and product quality.
