Why choose Halnn CBN inserts to process rolls?
Mill Rolls can be divided into casting rolls and forging rolls, both of them have high hardness and large allowance, and are difficult to process. Especially for the large casting rolls with the casting defects such as sand, stomata and hard spot , it will required very high on the cutting tools.
Advantage
For high-hardness rolls, Halnn recommends solid CBN tools that can withstand large margin cutting. It is more stable than traditional cutting tools, and the production cost is increased. The application of dry cutting greatly reduces the production cost. As following about parameter.
