In the process of cutting granite, the diamond segment will encounter many problems. In addition to the problem of the diamond segment itself, there are three elements to pay attention to. This article mainly analysis the three major speeds in the granite cutting process and how to adjust them. The efficiency of the diamond segment is faster, and the consumption of the diamond segment can also be reduced.
The line speed represents the rotation speed of the saw blade in the process of cutting granite. The line speed is greatly affected by the mechanical limitation and the hardness of the cutting object. Most of the mechanical line speeds can be adjusted, but the adjustment range needs to be adjusted according to the machine. It depends on its own power or the old and new level of the equipment. In terms of cutting objects, the harder the granite, the linear speed should be reduced, otherwise the diamond segment will be quickly polished or even the knife will be stuck; the softer the granite, The line speed should be increased accordingly, otherwise it will cause the diamond segment to be smoothed slowly, and it will be difficult to open the edge. But there is an exception, that is, when using saw blades of different sizes, the line speed will also vary greatly.
The cutting speed refers to the moving speed of the saw blade when cutting the stone forward or backward. In actual work, the cutting speed of the diamond saw blade is greatly affected by the linear speed. The linear speed is lowered and the cutting efficiency of the machine is slow, the cutting speed is also reduced. On the contrary, the line speed is increased, the efficiency of the cutting is accelerated, and the cutting speed is also increased. It is difficult to adjust the cutting speed individually, so if you want to increase the cutting speed, there is no other way than to adjust the segment formula and choose a sharper segment product. Consistent with the linear speed, the cutting speed is related to the hardness of the granite. The harder the material, the slower the cutting speed, and the lower the hardness, the faster the cutting speed.
The plunge speed is also called the feed speed. It is the downward speed in the process of cutting granite. This parameter directly affects the cutting efficiency of the saw, the force of the saw blade and the heat dissipation of the diamond segment. Generally speaking, the Plunge speed is determined by the cutting depth. The deeper the cutting depth, the higher the cutting efficiency and the higher the sharpness of the diamond segment. However, if the cutting depth is shallow, the cutting efficiency is low, but the segment is well protected. In general, for cutting granite stone with uniform particles, the Plunge speed can be appropriately increased, otherwise the diamond segment will be quickly smoothed, but if cutting uneven stone, the cutting speed should be reduced, otherwise it will cause the diamond segment broken quickly, thereby reducing the service life of the diamond segment. The plunge speed should also be determined according to the cutting object. If cutting blocks, the cutting speed should be kept at 1-2mm. If cutting the slab, the cutting speed can be guaranteed to be 2-10mm. According to the principle of cutting deep for small pieces and shallow cutting for large pieces.
Generally speaking, during the cutting of granite, the diamond segment
is affected by the linear speed, the cutting speed and the plunge speed. If there are some situations such as high consumption and dullness of the diamond segment during the cutting process, you can try adjust these three speeds. , may be there have a miraculous effect.
