CM7220 series carbide turning inserts are purpose-built for stainless steel machining, delivering consistent and reliable cutting performance across a wide range of industrial applications through optimized coating technology and substrate formulation.
In general machinery manufacturing, CM7220 inserts are widely used in turning fluid control valves, hydraulic system components, and various stainless steel connectors. The low-friction coating effectively suppresses built-up edge formation, significantly improving machining stability and surface finish in mass production of austenitic stainless steels like 304 and 316L, reducing the need for subsequent polishing processes.
For the automotive industry, these inserts are ideal for machining stainless steel exhaust manifolds, chassis fasteners, and fuel line components. Engineered for continuous cutting at medium to high speeds, the inserts combine high wear resistance and impact toughness, ensuring dimensional accuracy while extending tool life and reducing tool change costs in high-volume production.
In shipbuilding and heavy industry, where components like corrosion-resistant structural parts and pipe flanges often use high-toughness duplex stainless steels, CM7220's robust substrate withstands the shock loads of interrupted cuts, minimizing chipping risk and meeting the strict stability requirements of heavy-duty applications.
In medical devices and food/pharmaceutical machinery, where hygiene and surface quality are critical, CM7220 prevents work-hardening during machining of medical instrument blanks and food-grade conveyor rollers, ensuring dimensional precision while reducing material adhesion to lower contamination risks.
Additionally, CM7220 performs reliably in precision stainless steel components for construction machinery and aerospace applications, covering external turning, internal boring, and facing operations to deliver efficient, stable cutting solutions for stainless steel machining worldwide.
