Why does the super thin 115 cutting disc burst during operation?
Super thin 115 cutting disc and 4 1/2 super thin cutting disc sometimes burst when operating. What are the reasons for this?
1. When the cutting piece is unevenly organized, the stress will accumulate in the weak tissue, causing cracking due to the torque force, thermal stress, tremor and other factors during the cutting process.
2. 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.
3. 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.
4. When the hardness of the cutting piece is high, the radial torque force received by the cutting piece will increase. Since the thickness of the cutting piece is usually less than 4 mm, the cutting piece may be broken.
