PublishedDate：2017-12-29
As we all know that Ni-based alloy is one type excellent material used in aerospace and Military industry.TheYield Strength is 192MPa, the cutting force is 50% higher than 45 steel, the Thermal Conductivity is about 20% of 45 steel, and it is easily produce BUE. So Ni-based alloy is a kind typical materials that difficult to machine. In current times, there are 3 type cutting tools can be used for machining ni-based alloy: carbide insert, ceramic cutters, cbn inserts, and cbn inserts will be the most suitable one.
