Temperature effect of diamond blades

The diamond blade is a cutting tool, which is widely used in the production and processing of hard and brittle materials such as marble and porcelain. The diamond blade is mainly composed of two parts; the base material and the cutter head. The cutter head is a part of the cutting during the application process. The cutter head will be consumed continuously during use, but the base material is not easy. The cutter head can often cut because it contains diamond, which is made of diamond. It is currently the hardest material, which is rubbed and cut in the cutter head to be processed. The diamond particles are encapsulated in the cutter head by metal materials. During the use process, the metal embryo is consumed together with the diamond, generally more The ideal situation is that the consumption of the metal blank is faster than that of diamond, which can not only ensure the sharpness of the cutter head but also ensure the longer service life of the cutter head. The factors that affect the high efficiency and service life of the diamond round blade are the sawing process Main parameters and diamond particle size distribution, concentration value, fusion agent strength, etc. According to the cutting energy, there are blade line speed, sawing concentration value and cutting speed.

Temperature effect
The traditional theory believes that the influence of temperature on the cutting process is manifested in two aspects: one is the graphitization of the diamond in the agglomeration; the other is the thermal force between the diamond and the embryo, which causes the diamond particles to fall off too early . New research shows that: the heat generated during the cutting process is mainly transmitted to the agglomeration. The temperature in the arc zone is not high, generally between 40 and 120°C. However, the temperature at the cutting point of abrasive grains is relatively high, generally between 250 and 700 °C. The coolant only reduces the average temperature in the arc area, but has little effect on the temperature of the abrasive grains. Such a temperature does not cause carbonization of high-purity graphite, but it will change the friction characteristics between the abrasive grains and the workpiece, and cause internal stress between the diamond and the additive, resulting in a global bending of the diamond invalidation principle. Studies have shown that the temperature effect is the most influential factor to damage the blade.
