Due to the force effect and temperature, thediamond saw segmenttends to be worn and damaged after a period of use. The main forms of diamond saw segment wear and tear are as follows: abrasive wear, partial crushing, large area crushing, shedding, and mechanical abrasion of the bonding agent along the cutting speed of the diamond saw segment. Let me talk about the wear and tear of diamond saw segments in detail. Here are some answers.
Here is the content list:
l The diamond saw segment is worn and damaged due to the force effect.
l Due to the temperature effect, the diamond saw segment is worn and damaged.
l The worn form of diamond saw segments.
In the sawing method of the diamond saw segment, the diamond saw segments subject to axial force and tangential force. because of the force within the circumferential direction and also the radial direction, the diamond saw segments wavy within the axial direction and concave within the radial direction. These 2 types of deformation can cause uneven rock cutting surface, waste of the stone, bang throughout sawing, and inflated vibration, leading to early breakage of diamond agglomeration and reduced lifetime of diamond saw segments.
The traditional theory believes that the influence of temperature on the diamond saw segment method is especially manifested in 2 aspects: one is to cause the graphitization of the diamond within the agglomeration. Second, the thermal stress between the diamond and also the matrix causes the diamond particles to fall off untimely. New analysis shows that the warmth generated throughout the cutting of diamond saw segments is specially transferred to agglomerates. The temperature within the arc zone isn't high, usually between 40°C and 120°C. Studies have shown that the temperature impact is that the biggest issue influencing the harm of the diamond saw segments.
First, abrasive wear. The diamond particles and also the sort components square measure perpetually rubbing, and also the edges square measure passivated into a flat surface, that loses the cutting performance and will increase the friction. The sawing heat of the diamond saw segment can cause a skinny layer of graphitization on the surface of the diamond particles, which can greatly scale back the hardness and increase the wear and tear.
Second, partial fragmentation. The surface of the diamond particles are subjected to alternating thermal stresses, and at the identical time, it's conjointly subjected to alternating cutting stresses, fatigue cracks can seem and partly broken, revealing sharp new edges, that could be an additional ideal wear pattern.
Third, giant square measures are broken. Diamond particles square measure subjected to impact load once cutting in and out, and also the additional distinguished particles and crystal grains square measure consumed untimely.
Fourth, shedding. The alternating cutting force causes the diamond particles to be swayed unceasingly within the bond to loosen them. At the identical time, the wear and tear of the bond itself throughout the sawing method of the diamond saw segment and also the sawing heat of the diamond saw segments often the bond. This reduces the holding force of the binder. once the cutting force on the particles is larger than the holding force, the diamond particles can fall off. notwithstanding what reasonably wear is closely associated with the load and temperature of the diamond particles. each of those depends upon the sawing method and cooling and lubrication conditions of the diamond saw segment.
