1. Good grinding performance and good processing appearance quality
Because cubic boron nitride abrasive tools can maintain the sharpness of the abrasive microblade for a long time, the machining accuracy and surface roughness of the processed workpiece will reach a more aspirational effect, so the durability of the workpiece can be increased by 10%-30% . Therefore, even the workpieces processed in batches will always have a higher shape, accuracy and consistency. Suzhou cbn grinding wheel grinding can obtain high dimensional accuracy and low surface roughness, and the processed surface is not easy to produce cracks and burns, and the residual stress is small. The processing surface quality has been improved, generally no cracks, not easy to burn, and can obtain residual compressive stress, significantly improve the fatigue strength of the workpiece, generally, the durability of the workpiece can be improved by 30-50%.
2. Strong wear resistance and long life
The grinding ratio of Suzhou cbn grinding wheel can reach 3500-5500, which is a hundred times higher than ordinary corundum grinding wheel and 3-5 times higher than diamond grinding wheel.
3. Environmental protection, pollution-free, energy saving and consumption reduction
There is not too much powder dust.
4. High operating efficiency and good generalized economic benefits
Sharp grinding, small grinding force, long dressing cycle of CBN grinding wheel, less dressing amount, long replacement time; long service cycle, high grinding ratio, better economic efficiency, good shape retention during use, no need for frequent Replacing the grinding wheel and dressing the grinding wheel save man-hours, improve working conditions, and facilitate processing operations.
Cubic boron nitride is not suitable for grinding hard alloys and non-metallic hard materials. Under the high temperature of grinding, CBN will have a chemical reaction when it meets alkaline aqueous solution. CBN grinding wheel will decompose in 300℃ alkaline solution, and it can decompose slightly in boiling water. As a result, the crystal shape of abrasive grains will be destroyed. Therefore, during grinding, Only oil-based coolant can be used instead of water-based coolant.
The above is the analysis of the relevant process characteristics of the Suzhou cbn grinding wheel by the editor, mainly the above parts, I hope it will be helpful to everyone.
