The Main Features of Stainless Steel
The machinability of stainless steel varies according to alloy elements, heat treatment and manufacturing processes (forging, casting, etc.). Usually the machinability decreases as the alloy content increases, but materials that are easy to cut or improve the machinability are present in all types of stainless steel.
Long chip material.
Chip control is easier in the processing of ferroprotein/Mars materials, but more complex in Australoit and bipoliment stainless steel processing.
Specific cutting force: 1800-2850 N/mm2.
High cutting forces, crumb tumors, high heat and hardened surfaces are produced during machining.
The higher nitrogen (N) content in austere materials increases strength and corrosion resistance, but reduces machinability and hardens deformation.
Add sulfur (S) to improve the machinability of the material.
High carbon content (-0.2%) Large rear face wear can occur.
Mo and N reduce machinability, but they provide acid resistance and increase high temperature strength.
The mechanical properties of stainless steel have a great influence on the characteristics of the cutting process, in which thermal conductivity plays a great role. The lower the thermal conductivity of the processed steel, the less heat is taken away by the chips, and the more heat accumulates on the tool. Due to the toughness of stainless steel, high strength, large cutting force and poor thermal conductivity, so the heat is difficult to spread when cutting, resulting in the tool is easy to heat, and even with the processing of general steel much lower cutting speed for machining, will still make the tool produce a lot of heat, reducing the cutting performance of the tool.
In stainless steel metal tissue, due to dispersed carbonized material impurities, turning will produce a high abrasiveness, which makes the tool easy to wear. Stainless steel maintains its hardness and strength at high temperatures, while tool materials produce plastic deformation due to exceeding the thermal hardness limit. Stainless steel has a high adhesion, so that the material "bonded" to the tool and produce a chip tumor, to turning difficulties, affecting the surface roughness of parts.
The strength of stainless steel is high, which increases the cutting force that it is used on the tool, and the uneven cutting process enhances the vibration of the tool. In addition, stainless steel castings and forging rough surface has a high hardness of oxide skin, as well as non-continuous and irregular shape, will bring difficulties to turning stainless steel material, to ensure that the knife has a better rigidity and good edge grinding quality.
