Why does the super thin 115 cutting disc burst during operation?

Sometimes when using super thin 115 cutting disc, there will be cracks. Why? Many people expect this to happen, but some users don’t understand what causes this. Today, aurora abrasives Let's give you a brief summary.
1. When the cutting piece resin lacks toughness, since the grinding wheel piece is always in a negative pressure state during the cutting process, lateral stress is inevitably generated, and when the cutting piece cannot resist the lateral force, the grinding wheel piece is broken.
2. When the cutting piece is not uniform, the stress will accumulate in the weak tissue, causing the rupture due to the torque force, thermal stress, tremor and other factors of the cutting process.
3. When the hardness of the cutting piece is high, the radial torque force received by the cutting piece will increase, and since the thickness of the cutting piece is usually less than 4 mm, the cutting piece may be broken.
4. The flatness of the cut piece is poor, the structure of the cut piece is uneven, the hardness of the cut piece is high, and the resin of the cut piece lacks toughness. When the flatness of the cutting piece is poor, the cutting surface is curved, and as the cutting depth increases, the cutting piece is subjected to lateral stress increase, and the rounding of the grinding wheel piece causes a "soft film" to be broken, and the rupture is continued.
Therefore, to understand the cause of cracking when cutting ultra-thin cutting blades, it is necessary to avoid these problems in future use.

We really got to learn important information about these materials. - Steven C Wyer
