1. Halnn Solid CBN Insert for machining high chrome cast iron pump

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.

3.Application Case

Halnn BN-K1 Solid CBN Inserts interrupt turning pump impeller

Process Difficulties:

• Impeller belong to castings, it will have some casting defects;
• Each Impellers has 5~12 blade, will be haeavy interrupt turning condition when machining cylinder and end surface;
• The working environment will extreme bad.
