Abstract The addition of copper and sulfur can improve the cutting performance of the pre-hardened plastic mold steel, and the effect of improving the cutting performance is similar, both of which have the effect of wrapping lubrication and reducing friction. Four kinds of P20 plastic mold steels were adjusted to the same hardness level by heat treatment process. The microstructure and mechanical properties were compared by optical microscope, scanning electron microscope, transmission electron microscope and universal tensile tester. At the same time, their cutting and polishing properties were compared by high-speed turning experiment and optical profiler. The results show that under the same cutting conditions, the addition of sulfur will reduce the cutting force of steel by about 13%, and the cutting life of the tool is significantly prolonged, but the po-lishing performance decreases, and the roughness value increases by about 23%. The addition of copper not only reduces the cutting force of the steel by about 10%, but also prolongs the cutting life of the tool, and the surface finish of the steel after cutting increases by about 15%.
