1. Advantages of Halnn CBN Tools application in Milling.

 Halnn, Since its inception, it has adhered to the initial business philosophy of “not seeking big and complete, only high precision”. It focuses on the research of CBN tools for brittle and hard materials. Its milling cutting tools have been tested for a long time, and recognized by the market and has gradually replaced the European CBN milling cutting tools for the high-end market in China.

Halnn CBN tools mainly mill high hardness cast iron, high hardness / strength steel, gray cast iron and other materials, such as high hardness cast iron is recommended BN-K1 grade CBN tool, high hardness / strength steel is recommended BN-S20 grade CBN tool, gray cast iron is recommended BN-S300 grade CBN tool, and of them are solid CBN tools as above, which not only have high hardness and wear resistance, but also have high impact toughness and fracture resistance.

2. How to mill High Manganese Steel parts.

Due to the high hardness of high manganese steel itself, coupled with work hardening, it is more difficult to mill high manganese steel. Currently, the tool materials on the market include traditional carbide tools, coated carbide tools, ceramic tools and CBN tools. Among them, traditional carbide tools are suitable for processing workpieces with hardness below HRC40 due to their low hardness. The hardness and performance of coated carbide tools are higher than those of uncoated traditional carbide tools, but the surface coating is wear resistant. The layer is thinner, and when it encounters a hard spot, a chipping may be generated. After the surface wear layer collapses, the performance is the same as that of the uncoated traditional carbide tool, and the tool cost is high; the ceramic tool does not need to say it is very well aware of the brittleness, can only be used in the finishing process of small amount of cutting depth and feed rate; for high manganese steel with large margin, it is recommended to choose CBN tool, especially Halnn superhard BN-S20 grade CBN tool can not only mill high-manganese steel, but also cut it intermittently. It will not collapse when it encounters hard spots.
