304 Stainless Steel Part – CNC Milling Operation

This project involved the precision CNC machining of a component manufactured from 304 stainless steel, a material widely used in engineering applications for its corrosion resistance, strength, and durability. The goal of the operation was to produce a high‑accuracy part that met strict dimensional requirements while maintaining a clean, professional finish.

The process began with material verification, ensuring the stainless steel stock was free from defects and suitable for machining. Because 304 stainless steel work‑hardens quickly, the machining strategy required careful planning. Tool selection, spindle speeds, feed rates, and coolant flow were all optimised to maintain stable cutting conditions and prevent excessive heat buildup.

Using the approved CAD model, we generated CNC toolpaths tailored specifically for stainless steel machining. The part was then produced using controlled CNC milling operations, with each pass monitored to maintain accuracy and surface quality. Consistent depth of cut, proper chip evacuation, and continuous coolant application were essential to achieving a smooth and reliable machining process.

After machining, the component underwent deburring and edge finishing to remove sharp edges and ensure a clean, safe, and professional appearance. No fabrication or welding was involved , the entire part was created solely through subtractive machining.

A full quality‑control inspection was carried out using calibrated measuring tools. All critical dimensions were checked against the engineering drawing, and the results were recorded in a structured inspection sheet for traceability. The final measurements confirmed that the part met the required tolerances and surface specifications.

This project highlights our capability to machine challenging materials like 304 stainless steel with precision, consistency, and strong process control. It demonstrates our commitment to delivering high‑quality components supported by disciplined machining practices and professional documentation.
