The ultra-thin cutting disc manufacturer tells you that the ultra-thin cutting wheel is mainly used for precision grooving and cutting, and generally adopts the deep-cut slow-feed grinding method. It has the characteristics of large grinding depth, low feed speed, large contact area between the grinding wheel and the workpiece, narrow cutting gap, high metal removal rate, high grinding accuracy, good surface quality and high material utilization.
1. The overall cutting wheel of ultra-thin cutting disc manufacturers has thin thickness (mostly less than 0.5mm), small outer diameter (20-100mm), fine particle size, high size and shape accuracy, light weight, generally at high speeds Use under conditions. The general speed is 5000-40000rpm.
2. Ultra-thin cutting disc manufacturers' cutting disc base type cutting wheels are mostly thick (0.5-2mm), large in diameter (100-200mm), coarse in size, and low in precision. They are generally used under conditions of low speed and large cutting depth. The general speed is 3000-10000rpm.
3. The ultra-thin cutting wheels of ultra-thin cutting disc manufacturers mostly use fine-grained grinding wheels. Generally, the thinner the thickness of the grinding wheel, the smaller the abrasive particle size will be, and the processed surface quality is good. However, the finer the abrasive grain size, the corresponding cutting sharpness decreases, and the feed speed should be reduced accordingly to adapt to the machinability of the abrasive grain size.
4. The cutting depth of the ultra-thin cutting blades of the ultra-thin cutting blade manufacturers is generally determined by the user according to the cutting parts. Most of the cutting adopts the slow feed grinding process, and the depth is cut at one time. In this way, because the cutting wheel is thin and the cutting conditions are poor (mostly 3 surfaces contact the workpiece), it is difficult to dissipate heat, so it is necessary to increase (flow, pressure) to cool the cutting area.
5. When the cutting wheel cannot be cut or the workpiece is chipped just after being used by the user, it is recommended to increase the cutting speed or reduce the feed rate; when the cutting wheel cannot be cut or chipped after a period of use, it is recommended to use appropriate Whetstone of grain size sharpens the surface of the grinding wheel to adjust its sharpness.
6. The surface quality and cutting performance of the workpiece are mainly related to the particle size of the ultra-thin cutting wheel abrasive. The finer the particle size, the better the surface finish. At the same time, it is also related to factors such as workpiece material, hardness, cutting amount, machine tool conditions, and processing requirements.
7. The ultra-thin cutting blades produced by manufacturers of ultra-thin cutting blades are generally shaped and sharpened before they leave the factory, and users can use them directly. If the user needs further shaping, it is recommended to use green silicon carbide or white corundum whetstone, the particle size is 1-2 numbers coarser than the particle size of the cutting wheel; if the user needs to further sharpen or sharpen after a period of time, it is recommended to use green silicon carbide or white corundum Whetstone, the particle size can be selected 1-2 numbers or the same number finer than that of the cutting wheel.
8. The cutting amount is generally related to the processed material, hardness, precision, processing requirements, etc. It is recommended to use it under the original conditions of the user when it is used for the first time, and do not change the cutting amount easily.
9. The user's operating conditions are also the main factors affecting the cutting performance, especially the axial string movement, radial runout of the machine tool, the parallelism of the flange, and the accuracy of dynamic balance, which directly affect the cutting accuracy of the cutting wheel.
