Performance and characteristics of 304 stainless steel cutting

High cutting force and high cutting temperature. 304 stainless steel has large plasticity, good toughness, high thermal strength, and is accompanied by severe work hardening during cutting, so the power consumption during cutting is large, resulting in an increase in cutting resistance. Due to the large cutting force and cutting power, a lot of heat is generated.

Moreover, the thermal conductivity of 304 stainless steel is poor, so that the heat generated by plastic deformation and knife and chip friction during cutting is concentrated on the interface between the main shear zone and the knife and chip, and the heat dissipation conditions are poor, resulting in high cutting temperature. .

The chips of 304 stainless steel are not easy to break and stick easily. 304 stainless steel has great plasticity and toughness, and the banded chips during cutting are not easy to break, making chip breaking difficult. These chips that surround or accumulate around the workpiece or the tool can easily scratch the machined surface of the workpiece.

Under the influence of high cutting temperature, 304 stainless steel has a strong affinity with other metals, and the rake face of the tool is prone to the phenomenon of tool-chip adhesion and the formation of built-up edge, thereby affecting the quality of the machined surface.
