SS420 SS430 CNC Stainless Steel Parts Multiple Steps CNC Precision Pin Shaft

Stainless steel spring pin shaft, with multiple steps, CNC precision processed component

Core Application Scenarios

After CNC machining, stainless steel is widely used in aerospace (structural components, engine parts), medical (surgical instruments, implants), automotive (exhaust systems, battery trays), electronic consumer goods (middle frames, rotating shafts) and other fields. It meets scene requirements by virtue of its corrosion resistance, high strength, biocompatibility and other properties.

Key Machining Precautions

Cutting Tools: Use TiAlN-coated cemented carbide tools for rough machining and CBN tools for finish machining; optimize rake angle (5°-10°), relief angle (10°-15°) and chip holding space.
Cutting Parameters: Reduce speed by 30%-50% compared with ordinary steel; adopt large feed rate for chip evacuation in rough machining and small feed rate for precision in finish machining; side cutting depth shall not exceed 50% of tool diameter.
Process & Cooling: Use trochoidal milling for rough machining and climb milling for finish machining; clamp thin-walled parts with vacuum suction cups; apply full-flow cooling with extreme pressure emulsion/cutting oil (avoid dry cutting).
Troubleshooting: Reduce speed and increase feed rate for tool adhesion; decrease cutting depth and enhance cooling for thermal deformation; lower feed rate and shorten tool overhang for tool chipping.

Core Scene Advantages

Performance Upgrade: Significantly improved corrosion resistance, fatigue strength and wear resistance; component service life extended by 2-4 times; maintenance cycle prolonged from 3 months to 2-3 years.
Safety & Compliance: Smooth and burr-free surface; compliant with medical ISO 13485 and food GB 4806.9 standards; high stability in high-pressure and high-temperature scenarios.
Flexible Design: Capable of machining thin-walled parts, complex curved surfaces and micro holes; achieves lightweight (30%-40% weight reduction) and multi-scene adaptation; reduces procurement costs.
Efficiency Improvement: Part tolerance controlled at ±0.005mm with strong interchangeability; assembly efficiency increased by 50%; integrated machining simplifies processes and shortens production cycle by 40%.
Economic & Environmental Protection: Total life-cycle cost reduced by 20%-30%; scrap rate ≤0.5%; recycling rate up to 90%; residual value 2-3 times that of ordinary steel.
