Materials and Manufacturing Processes of Stainless Steel Bolts

Bolts made from special stainless steel materials such as 304, 316, and 17-4PH require a perfect balance between high strength and corrosion resistance. However, stainless steel presents unique challenges in bolt processing: extremely high thread forming precision is required, the head structure needs complex geometry, and the material's work hardening tendency increases manufacturing difficulty. Only through five-axis CNC precision machining can all bolt features be formed in a single setup, ensuring the optimal combination of geometric accuracy and material properties.

 

The Art of Precision Thread Forming with Five-Axis Linkage

The manufacturing process begins with high-strength stainless steel bars. In a temperature-controlled machining environment, five-axis CNC machine tools demonstrate the precision control capabilities of modern manufacturing through multi-process integrated machining:

 

One-time Full Thread Forming Technology: Unlike traditional turning threading, five-axis CNC uses cyclone milling or thread milling processes, achieving high-precision thread forming in a single operation through multi-axis linkage between the tool and the workpiece. This method not only ensures the integrity of the thread profile but also achieves excellent surface finish through continuous cutting, significantly improving the thread's fatigue life.

Integrated machining of complex heads: For bolts requiring special drive structures or irregular head designs, the multi-angle machining capabilities of five-axis CNC enable seamless integration of complex geometric features. The tool approaches the workpiece from different directions, completing the precision machining of all head features in a single setup, ensuring absolute coaxiality between the head and the screw.

Five axis CNC workshop

The factory covers an area of approximately 2000 square meters and has mastered core processing technologies. Equipped with high-end precision production equipment, CNC precision: CNC lathes, five axis CNC, four axis CNC, stamping equipment, die-casting equipment, and other 2.5-dimensional testing equipment.

We strictly control every step from design drawings to finished product delivery. Select high-quality aluminum alloy materials such as 6061 and 7075 to ensure that the parts have excellent strength, lightweight, and corrosion resistance. Our processing accuracy can reach ± 0.01mm, which can perfectly meet the requirements of complex structures, precise hole positions, and high standard surface treatments (such as anodizing, sandblasting, conductive oxidation, etc) .

For surface treatment, our suppliers have been cooperating with us for many years. They have rich experience and are familiar with each other's quality requirements. Stable quality and greater assurance. For example, heat treatment, painting, powder coating, blackening, silver/gold plating, electrolytic polishing, nitriding, phosphating, nickel/zinc/chromium/TiCN, anodizing, polishing, passivation, sandblasting, galvanizing, heat treatment, hardening, laser marking, etc. can be carried out according to customer requirements.
