Machining Process of 303 Stainless Steel Motor Shaft with Keyways and Steps

CNC Turning
CNC turning is used to accurately shape the diameter and steps of the 303 stainless steel motor shaft with keyways and steps, achieving tight roundness and dimensional tolerances often within ±0.01 mm for reliable fit and rotation.

 

Milling
Milling is applied to cut precise keyways and complex features on the 303 stainless steel motor shaft with keyways and steps, ensuring accurate width and depth according to customer drawings with repeatable positioning accuracy.

 

Grinding
Grinding provides superior surface finish and straightness for critical bearing surfaces on the 303 stainless steel motor shaft with keyways and steps, delivering low roughness values (Ra 0.2–0.8 µm) for smooth operation and long service life.

 

Surface Finish: 303 Stainless Steel Motor Shaft with Keyways and Steps
 

Passivation

Passivation is a widely-used metal finishing process to prevent corrosion. Passivation is a post-fabrication best practice for newly-machined stainless steel parts and components. Benefits include:
● Chemical film barrier against rust
● Extended life of the product
● Removal of contamination from product surface
● Reduced need for maintenance.

Polishing

Polishing is an important finishing step that helps eliminate imperfections and impurities from stainless steel and other metal surfaces. Chemical polishing for stainless steel has numerous benefits for stainless steel parts:
● It allows the polishing of complex-shaped workpieces and components.
● It's an affordable polishing method that doesn't require specialized fixtures or a DC power source.
● It's a highly efficient process that allows multiple stainless steel parts to be polished simultaneously.
● It provides an ultraclean surface finish.
● It improves the localized corrosion and mechanical strength plus extends the service life of stainless steel workpieces.
● It allows control over the level of protection on the surfaces.
