Analysis of grinding characteristics of cutting wheels
What are the grinding characteristics of ultra-thin cutting wheels? What are the points for attention in the use of ultra-thin cutting wheels? The following is the introduction of Xiaobian:
The ultra thin China long life grinding wheel is mainly used for precise grooving and cutting, and the deep and slow feed grinding method is adopted. It has the characteristics of large grinding depth, small feed speed, large contact area between grinding wheel and workpiece, narrow slit, high metal removal rate, high grinding accuracy, good surface quality and high material utilization.

The general laws are as follows:
1). The monolithic cutting blade grinding wheel is thin in thickness (mostly less than 0.5mm), small in diameter (20-100mm), fine in size, high in shape and position accuracy, light in weight, and generally used at high speed. The general speed is 5000-40000rpm.

2). Most of the matrix cutting grinding wheels are thick (0.5-2 mm), large diameter (100-200 mm), coarse grain size and low precision, which are generally used in the condition of low rotational speed and large cutting depth. The general speed is 3000-10000rpm.

3). Ultra-thin cutting grinding wheels use fine grain size, and generally the thinner the thickness of the abrasive grain size will be correspondingly fine, good surface quality. However, the finer the abrasive particle size, the lower the cutting sharpness, the lower the feed speed, so as to adapt to the machinability of abrasive particle size.

4). Ultra-thin cutting grinding wheel cutting depth is generally determined by the user according to the cutting parts, its cutting mostly adopts slow-feed grinding process, the depth of one cut to. In this way, because the grinding wheel for stainless steel is thin and the cutting conditions are poor (mostly 3 contact workpieces), it is difficult to heat dissipation, so it is necessary to increase (flow, pressure) on the cutting zone cooling.

5). It is suggested to increase cutting speed or decrease feed rate when cutting grinding wheel is immovable or workpiece breaks when it is used on the machine at the user's place. When cutting wheel is immovable or breaks after a certain period of use, it is suggested to cut the surface of grinding wheel with appropriate grain size of oil stone to adjust its sharpness.

6). The surface quality and cutting performance of workpiece are mainly related to the abrasive grain size of ultra-thin cutting grinding wheel. The finer the grain size, the better the surface finish. At the same time, it also has something to do with the factors such as workpiece material, hardness, cutting amount, machine condition, processing requirement and so on.

7)the ultra thin China long life grinding wheel has been trimming and sharpening before the factory is ready, so the user can use it directly. If the user needs further shaping, it is recommended to use green silicon carbide or white corundum oil, the particle size of the grinding wheel is 1-2 larger than that of the cutting wheel; if the user needs to further cut or use a section after cutting, it is recommended to use green silicon carbide or white corundum oil, the particle size of the cutting wheel is 1-2 smaller than that of the same size.

8)Cutting parameters are also generally related to the material to be processed, hardness, accuracy, processing requirements and so on. It is recommended that the best initial use in the user's original conditions to use, do not easily change the cutting parameters.

9)User's operating conditions are also the main factors affecting cutting performance, especially axial series, radial runout of machine tool spindle, flange parallelism, dynamic balance accuracy and so on, which directly affect the cutting accuracy of cutting grinding wheel.

High-speed cutting of all kinds of tool steel, ceramics, cemented carbide, thickness from 0.1 mm, its precision and thickness tolerance is very high. This series of products have the characteristics of high cutting precision, quick work efficiency and low material consumption, especially suitable for cutting high hardness steel, analyzing material cutting, sample cutting or precious metal, lithofacies, various crystal and ceramic slices, glass and alloy, semiconductor, integrated circuit board PCB, etc., widely used in mold manufacturing industry and steel Wood factory.
