What are the hazards of using inferior raw materials in grinding wheels?
1. Prone to fragmentation, causing safety accidents
• Inferior raw materials (such as abrasives with many impurities and binders with insufficient strength) will make the structure of the grinding wheel unstable, which may suddenly fragment during high-speed rotation.
• High-speed flying fragments may hit operators or surrounding equipment, causing personal injuries such as cuts and bruises, and even triggering more serious safety accidents.
2. Poor grinding performance, affecting work quality and efficiency
• Inferior abrasives with insufficient hardness and uneven particles will reduce grinding accuracy, resulting in problems such as scratches and unevenness on the workpiece surface, thus affecting product quality.
• They are prone to clogging and wear too quickly during grinding, requiring frequent replacement of grinding wheels, which reduces work efficiency and increases production costs.
3. Poor heat resistance, posing a fire hazard
• Inferior binders have weak high-temperature resistance. Under the high temperature generated by long-term high-speed grinding, they may soften or melt, leading to the failure of the grinding wheel.
• If excessive heat accumulates, it may also ignite surrounding combustibles, posing a fire risk.
4. Increasing equipment loss
• When the grinding wheel is unbalanced or has uneven hardness, it will cause violent vibration during grinding. Long-term use will accelerate the wear of machine tools and other equipment, shortening their service life.
Therefore, using high-quality grinding wheels that meet standards is an important prerequisite for ensuring operational safety and improving work efficiency and quality.
