Cracks that occur during the glass processing with a water jet cutting machine are often caused by malfunctions of the water jet equipment. The following will analyze the faults that may cause cracks in the glass cut by water jet cutting machines.
1. Improper adjustment of water jet pressure
The cutting pressure of the water jet cutting machine is a key factor affecting the cutting efficiency and quality. If the pressure is too high, it will cause the water flow to impact too strongly, resulting in cracks in the glass. Therefore, when using a water jet cutting machine, it is necessary to reasonably adjust the cutting pressure according to the material and thickness of the glass to ensure the stability and effect of the cutting process.
2. Wear or blockage of sand pipes and nozzles
The sand pipe and nozzle are the key components of the water jet cutting machine, and their quality and condition directly affect the cutting effect. If the sand pipe or nozzle is severely worn, it will cause uneven water flow, generate impact force, and subsequently lead to cracks in the glass. In addition, if the sand pipe or nozzle is clogged, it will also affect the stability of the water flow and the cutting effect. Therefore, it is necessary to regularly inspect and replace vulnerable parts such as sand pipes and nozzles to ensure the normal operation of the equipment.
3. the quality of the sand grains is poor
The quality of the sand grains used in water jet cutting machines also has a significant impact on the cutting effect. If inferior sand grains are used, it will lead to uneven water flow and unstable cutting force, which in turn will cause cracks in the glass. Therefore, when choosing sand grains, it is necessary to select those of good quality and uniform size to ensure the stability and effectiveness of the cutting process.
4. Failure of the cooling system
During the cutting process, water jet cutting machines generate a large amount of heat. If the cooling system malfunctions, it will cause the equipment to overheat, thereby affecting the cutting effect and the quality of the glass. Therefore, it is necessary to regularly inspect the operation status of the cooling system to ensure the normal operation of the equipment.
