The Advantages and Applications of CBN Inserts Hard Turning

The advancement in technology makes it increasingly difficult to create large-scale bearings with high precision. The tolerances have also reached P4 or even P5. Large bearings are typically constructed with CNC Lathes as well as Grinding Tools. Because of the limitations of grinding the efficiency and price are very low.

The superhard cutting tools solid cbn inserts manufacturers can be used in a variety of cold-processing techniques to substitute grinding. This article will show you how to turn bearing rings made of hard material. The roughness of the surface could be as high as Ra0.40.8 and be in line with the requirements of the bearing.

For hard turning bearings the initials of the cbn insert

CBN Insert is one of the most effective materials for machining ferrous metals. It has high hardness and wear resistance. It is second only in importance to diamond tools. CBN Insert is efficient when cutting high-hardness materials.

CBN Insert has high stable performance and high temperature red hardness When the temperature of cutting is high, the material will soften, which will be beneficial to the cutting process.

CBN Insert is very antioxidant and doesn't react with iron when temperatures are over 1200-1300?. However, it will undergo hydrolysis up to 1000?. When you use full cbn inserts or cutting bearings, it's essential to use dry cutting methods. Read for more info here: https://www.sundicuttingtools.com/products/full-solid-cbn-inserts/

CBN Insert has low Co-efficient of friction. It does not be able to easily create the chipping layer and can improve the quality of the surface of the piece.

CBN materials for hard-turning bearings

The allowance for the machining of large scale bearing is large, we usually use solid cbn insert to try to minimize the cutting process and increase the efficiency. And BN-S20 Solid CBN Insert is one of the most commonly utilized cbn components.

The BN-S20 are part of solid cbn inserts manufacturers, and the hardness is around HRC951000 and adopt ceramic as the binder, which will provide excellent wear resistance and high chemical resistance in high temperature.

For example Machining wind power bearings of dimensions of 1900mm in diameter and 130mm in thickness If you use a grinding process the time for grinding is approximately 18 hours; if use turning instead of grinding, it only needs about 4.5h. And the roughness can reach Ra0.3um,the processing efficiency of turning is about four times that of grinding. All costs are only 20 percent.

The advantages of cbn inserts hard-turning bearings

(1) The efficiency of the company has increased multiple times

(2) It is able to be ordered in large amounts and is extremely durable.

(3) Reducing the impact of pollution In comparison to grinding processes chips are easy to reclyed. Turning process doesn't need cutting fluid.

Conclusion

CBN cutting tools that incorporate CNC Lathe can be used to turn the bearings that are hard turning. This improves the efficiency of the work process and lower tool costs. As the market grows, more bearings manufacturers are using CNC inserts instead of grinding.
