2.  Characteristics of BN-S20 solid CBN inserts machining high manganese steel

• The CBN Content and Cutting edges of BN-S20 are both researched specific for processing high manganese steel castings, it can not be used to process ordinary mild steel such as 45 # steel.
• The cutting depth of BN-S20 Solid CBN Insert can be above 7mm, BN-S20 has better impact resistance than ceramic insert and common cbn inserts. Especially for the castings in the bad processing environment, BN-S20 can be used for rough machining, no need grinding first, which can help save the time.
• With BN-S20 solid cbn insert machinig high manganese steel, the feeds can range depending on the main angle of the tool holder, can't be same cutting condition.
• BN-S20 belong to indexable insert(including turning and milling insert), not only can be used for machining high manganese steel castings, but also can be used for machining high speed steel rolls, forged steel rolls, large scale bearing steels GCr15, and other high alloy cast steel,ect.

Process Difficulties:

• Plastic deformation, severe processing har-dening;
• Large plasticity, easily to form BUE;
• Large cutting force, high toughness, not easy to break.
• Due to the large cutting force, the unit cutting power increases, the heat generated per unit time and high manganese steel itself poor thermal conductivity, the cutting zone temperature up to 1000 ℃, severe tool wear, tool life is low.
