(I) on Grinding and Use Precautions of Grinding Wheel
Release time:
2023/08/24
Ultra-thin cutting grinding wheels are mainly used for precision grooving and cutting, and generally use deep and slow feed grinding. It has the characteristics of large grinding depth, small feed speed, large contact area between grinding wheel and workpiece, narrow kerf, high metal removal rate, high grinding accuracy, good surface quality and high material utilization rate. The general rules are as follows: 1. The whole type cutting wheel is thin (mostly below 0.5mm), small outer diameter (20-100mm), fine particle size, high precision of size and shape, light weight, and is generally used under high speed conditions. 2. The matrix type cutting grinding wheel is mostly thick (0.5-2mm), large diameter (100-200mm), coarse grain size and low precision, and is generally used under the condition of low speed and large cutting depth.
Ultra-thin cutting grinding wheels are mainly used for precision grooving and cutting, and generally use deep and slow feed grinding. It has the characteristics of large grinding depth, small feed speed, large contact area between grinding wheel and workpiece, narrow kerf, high metal removal rate, high grinding accuracy, good surface quality and high material utilization rate. Its general rule is as follows:
1. The whole type cutting grinding wheel has thin thickness (mostly below 0.5mm), small outer diameter (20-100mm), fine particle size, high precision of size and shape and position, light weight, and is generally used under high speed conditions.
2. The matrix type cutting grinding wheel is mostly thick (0.5-2mm), large diameter (100-200mm), coarse grain size and low precision, and is generally used under the condition of low speed and large cutting depth.
3. Ultra-thin cutting grinding wheels use fine grain size, and generally the thinner the thickness of the abrasive grain size will be correspondingly thinner, the processing surface quality is good. However, the finer the abrasive particle size, the lower the cutting sharpness, and the feed speed should be reduced accordingly to adapt to the machinability of the abrasive particle size.
4. The cutting depth of the ultra-thin cutting grinding wheel is generally determined by the user according to the cutting parts. Most of its cutting adopts the creep feed grinding process, and the depth is cut at one time. In this way, due to the thin cutting wheel and poor cutting conditions (mostly 3-sided contact with the workpiece), it is difficult to dissipate heat, so it is necessary to increase the cooling of the cutting area (flow, pressure).
5. When the cutting wheel is not cut or the workpiece is broken when it is just used on the machine at the user's place, it is recommended to increase the cutting speed or reduce the feed rate; When the cutting or breaking occurs after a period of use, it is recommended to use the appropriate size of the oil stone to cut 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 abrasive particle size of the ultra-thin cutting wheel, and the finer the particle size, the better the surface finish. At the same time with the workpiece material, hardness, cutting dosage, machine conditions, processing requirements and other factors are also related.
7. Ultra-thin cutting wheels have generally been shaped and cut before leaving 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 oilstone, and the grain size is 1-2 sizes coarser than the grain size of the cutting grinding wheel. If the user needs to further cut the edge or use it for a period of time, it is recommended to use green silicon carbide or white corundum oilstone, and the grain size is 1-2 or the same number finer than the grain size of the cutting grinding wheel.
8. The amount of cutting 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 for the first time, and do not easily change the amount of cutting.
User conditions of use is also the main factor affecting the cutting performance, especially the machine tool spindle axial series movement, radial runout, flange parallelism, dynamic balance accuracy, etc. directly affect the cutting accuracy of the cutting wheel.
