Stainless steel machining is a subtractive manufacturing process that utilizes computer numerical control (CNC) systems to shape and refine components from stainless steel, a material prized for its exceptional corrosion resistance, strength, and durability. While stainless steel is more challenging to machine than aluminum due to its hardness, tendency to work-harden, and high heat generation, modern CNC techniques and specialized tooling enable precise fabrication of complex geometries with tight tolerances. This process is widely employed in industries demanding robust, long-lasting parts, such as medical devices, aerospace, automotive, marine, and food processing equipment.
