How to address the issue of difficult cutting for 304 stainless steel pipes? The formation of the work-hardening layer and the increase in cutting force inevitably lead to greater friction between the tool and workpiece, as well as a rise in cutting temperature. Moreover, stainless steel has a lower thermal conductivity and poor heat dissipation conditions, causing a concentration of a large amount of cutting heat between the tool and workpiece, which worsens the machined surface and severely affects the quality of the finished surface. High-temperature-resistant, good heat-conducting, wear-resistant, and hard tools should be used.
