Stainless Steel Micro Shafts for Motors, Electronics
Applications
● Machinery Equipment: Used in precision machinery as transmission and support components, requiring high strength and corrosion resistance.
● CNC Machines: Used in CNC machines to provide precise axial movement and high load-bearing capacity.
● Food Processing Equipment: Due to its corrosion resistance, stainless steel is ideal for use in food processing equipment, ensuring long-term use while meeting hygiene standards.
● Medical Devices: Used in medical devices because of their excellent corrosion resistance and high precision.
Manufacturing Process
● Material Selection: High-quality stainless steel materials, such as 304, 316, and 420 grades, are commonly used. These materials offer excellent corrosion resistance, strength, and toughness.
● CNC Machining: CNC (Computer Numerical Control) machining is the primary technique for manufacturing Ensuring high precision and low tolerance in the machining process.
● Heat Treatment: Some stainless steel shafts undergo heat treatment processes, such as annealing or quenching, to enhance hardness and wear resistance.
● Surface Treatment: The surfaces of stainless steel small shafts are often polished or ground to improve smoothness and reduce friction, enhancing corrosion resistance.
Technical Characteristics
| Feature | Specification | Application Benefit |
| Corrosion Resistance | Passes 1,000-hour salt spray test (ASTM B117) | Ideal for humid environments or chemical contact |
| Tensile Strength | 580-1,380 MPa (depending on grade) | Withstands 50N radial load without deformation |
| Dimensional Tolerance | 0.005mm (ISO 2768-fine) | Ensures precise fit in micro-mechanical assemblies |
