2. Characteristics of BN-K1 solid CBN inserts machining high chrome cast iron

BN-K1 is researched specific for high chromium cast iron in cutting edge and cbn content aspect.
The cutting depth of BN-K1 can be above 7mm, has better impact resistance than common ceramic insert and cbn inserts. Especially for heavy interrupt condition, BN-K1 can perform well, no need grinding first, which help the customers improve their efficiency.
When using BN-K1 machining high chromium cast iron pumps, we need to choose different cbn grade and the feeds depending on the machining sites.
BN-K1 not only can be used for machining high chromium cast iron component, also can be used for other high hardness castings, such as chilled cast iron rolls.
