Characteristics and application of CBN abrasive belt

As a kind of flexible grinding tool, the abrasive belt has many advantages such as small heat generation, high grinding efficiency and good shape retention compared with the fixed abrasive wheel. Therefore, in the modern industrial grinding process, It is used more and more widely.
CBN abrasive belts have high efficiency of grinding, good wear resistance, high surface quality and environmental protection. CBN hardness is second only to diamond, and its thermal stability is much higher than that of diamond. It is chemically inert to Fe metal and its alloy tools. Therefore, CBN abrasive processing of ferrous metals and their metal materials is unmatched by other common abrasives. This provides a new means 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 it.

CBN has the following advantages over conventional abrasives:

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. Its metal removal rate is also 10 times that of diamond.

2, CBN abrasive tools have excellent grinding performance, not only can be used for the processing of difficult-to-wear 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 of the workpiece, significantly improve the grinding The surface integrity of the rear workpiece increases the fatigue strength of the part, prolongs service life and increases reliability.

3, CBN grinding tools wear less, long service life, high grinding, reasonable use of good economic results.

4. When the CBN grinding tool is used, the shape and size change is extremely slow, and it is more suitable for high-precision parts of CNC machining center.

5, can maintain a sharp cutting edge for a long time, so the grinding force is small, which is conducive to the accuracy and smoothness of the parts, and can also reduce the power consumption of the machine tool.

6. The grinding temperature is lower, which can greatly improve the surface quality of the workpiece, avoid cracks, burns, tissue changes and other defects of the parts, improve the stress state of the machined surface, and prolong the service life of the parts.

7. Ordinary abrasive belts produce a large amount of dust during manual use, which will be harmful to the human body. Long-term use will cause “silicosis”.
