CBN abrasive belts have high grinding efficiency, good wear resistance, high surface quality and environmental protection characteristics. The hardness of CBN is second only to that of diamond, and its thermal stability is much higher than that of diamond. It has greater chemical inertness to Fe group metals and alloy tools. Therefore, the processing of ferrous metals and their metal materials by CBN abrasives is unmatched by other ordinary abrasives. This is to provide a new method for the processing of hard and tough materials that are difficult to machine. Diamond is suitable for processing hard and brittle materials, and CBN can complement each other.
Features and Applications
1. The hardness of CBN is much higher than that of ordinary abrasives. It is especially suitable for processing materials with high hardness, high toughness, high temperature, high strength and low thermal conductivity, and its metal removal rate is 10 times that of diamond.
2. The grinding performance of CBN abrasive tools is very good, not only can it be competent for the processing of difficult-to-grind materials, improve production efficiency, but also help to strictly control the shape and dimensional accuracy of the workpiece, but also effectively improve the grinding quality and significantly improve the after grinding. The surface integrity of the tool, thus improving the fatigue strength of the part, prolonging the service life and increasing reliability.
3. CBN abrasive tools have less wear, long service life, high grinding ratio, and good economic effects can be obtained by reasonable use.
4. When the CBN abrasive tool is used, the shape and size change very slowly, and it is more suitable for the high-precision parts of the CBN CNC machining center.
5. It can maintain a sharp cutting force for a long time, so the grinding force is small, which is beneficial to the improvement of the accuracy and smoothness of the parts, and can also reduce the power consumption of the machine tool.
6. The grinding temperature is low, which can greatly improve the surface quality of the workpiece, avoid defects such as cracks, burns, and tissue changes in the parts, improve the stress condition of the machined surface, and prolong the service life of the parts.
7. Ordinary abrasive belts produce a lot of dust during manual use, which is harmful to human health. Long-term use will cause silicosis.
