High-temperature alloys refer to a type of metal material based on iron, nickel and cobalt, which can work for a long time at high temperatures above 600°C and under certain stresses, and have excellent comprehensive properties. According to the matrix elements, they can be mainly divided into iron-based high-temperature alloys, nickel-based high-temperature alloys and cobalt-based high-temperature alloys, and are mainly used to manufacture turbine blades, guide blades and turbine disks for aviation, ships and industrial gas turbines.
As the most difficult material to process among all kinds of difficult-to-cut materials, high-temperature alloys have the following processing difficulties: (1) High resistance to plastic deformation and severe work hardening, resulting in large cutting forces, which are 2-3 times greater than those of ordinary steel. (2) Poor thermal conductivity, high temperature during cutting, causing rapid wear of the inserts. (3) Chips adhere to the cutting edge surface of the inserts, which is very easy to produce built-up edge, affecting the surface quality of the workpiece being processed.
In view of the above processing difficulties, Halnn Superhard provides a variety
