What are the difficulties in processing stainless steel parts

The main difficulties in processing stainless steel parts are as follows:

1. High cutting force and high cutting temperature
This type of material for stainless steel parts has high strength, large tangential stress and large plastic deformation during cutting, so the cutting force is large. In addition, the thermal conductivity of the material is extremely poor, causing the cutting temperature to rise, and the high temperature is often concentrated in the narrow area near the cutting edge of the tool, which accelerates the wear of the tool.

2. Severe work hardening
Stainless steel parts processing manufacturers tell you that stainless steel and some high-temperature alloy stainless steels are austenitic structures, and have a large work hardening tendency during cutting, which is usually several times that of ordinary carbon steel. The tool is cut in the work hardening area, which shortens the tool life.

3. Easy to stick to the knife
Stainless steel parts processing manufacturers tell you that both austenitic stainless steel and martensitic stainless steel have the characteristics of toughness and high cutting temperature during processing. When the tough chips flow through the rake face, sticking phenomena such as adhesion and welding will occur, which will affect the surface roughness of the processed parts.

4. Accelerated tool wear
Stainless steel parts processing manufacturers tell you that the above-mentioned materials generally contain high melting point elements, high plasticity, and high cutting temperature, which speed up tool wear, sharpen and change tools frequently, thereby affecting production efficiency and increasing tool usage costs.
