Rail cutting wheels are a common cutting product, but when using rail cutting wheels, they may break. Why is this? What are the reasons?
1. When the rail cutting wheel has uneven structure, due to factors such as torque, thermal stress, vibration, etc. during the cutting process, stress will accumulate in weak areas of the structure, leading to rupture.
2. When the rail cutting wheel resin lacks toughness, the grinding wheel will inevitably generate lateral stress due to the fact that the grinding wheel is always in a negative pressure state during the cutting process. When the rail cut off wheel cannot resist the lateral force, the grinding wheel will break.
3. The flatness of the rail cutting wheel is poor, the cutting blade structure is uneven, the hardness of the cutting blade is too high, and the resin of the cutting blade lacks toughness. When the flatness of the cutting blade is poor, the cutting surface is curved. As the cutting depth increases, the lateral stress on the cutting blade increases. Multiple round trips will cause cracks on the grinding wheel, resulting in "soft film", which will break if used continuously.
4. When the hardness of the rail cutting wheel is too high, the radial torque force on the cutting disc will increase. Since the thickness of the rail cut off wheel is usually less than 4mm, it will cause the cutting disc to break.
