Stainless steel processing

タイトルまたは説明

 Stainless steel processing difficulties mainly in the following aspects:
1. Large cutting force, cutting temperature is high. The large type material strength, shear stress when cutting large plastic deformation, thus cutting power. Besides poor thermal conductivity of the material, resulting in cutting temperature and high temperature tend to be concentrated in a narrow area near the edge of the tool, thereby speeding up the tool wear.
2. Severe hardening austenitic stainless steel as well as some high-temperature alloys are austenitic stainless steel, cutting work hardening tendency of large, usually a multiple of ordinary carbon steel, tool hardening region in cutting tool life shorten.
3.Easy to stick the knife. Whether an austenitic stainless steel or martensitic stainless steel are present when machining tough chips, high cutting temperature characteristics. When passing through the rake face tough chips, will produce bonding, welding, etc. stick knife phenomenon, affecting the surface roughness of machined parts.
4. The tool wear faster. The above materials generally contain refractory elements, large plastic cutting temperature is high, the tool wear rate, sharpening, tool change frequently, thus affecting the efficiency of production, improve the use of the tool costs.
