Stainless Steel Ball Bearing Production Process

One,Stainless Steel BearingsThe simple production process of steel balls: blank forming → descaling → coarse grinding → soft grinding → heat treatment → blank forming → polished ball (or filing → soft grinding) → hard grinding → fine grinding → precision grinding (or polishing) → super-fine grinding. Detailed production process of steel balls: 1. Wire drawing: Stretch the wire material to the required diameter using a drawing machine; 2. Cold heading (forging): Place the drawn wire into a steel ball cold heading machine, and form the ball blank by using the steel mold inside; 3. Polishing: The two cast iron grinding ball round plates in the polishing machine press and file the cold heading ball blank to remove the outer ring and two poles; 4. Soft ball: The two cast iron grinding ball round plates in the soft ball machine file the polished ball blank to achieve the required ball diameter and surface roughness; 5. Heat treatment: After carburizing, quenching, and tempering the ball in the heat treatment furnace, it gains a certain carburized layer, hardness, toughness, and crush load; 6. Hard grinding: The abrasive wheel round plate in the grinder presses and grinds the heat-treated ball blank to remove the black oxide layer on the surface and correct the ball's accuracy; 7. Precision grinding/Polishing cleaning: Precision grinding: Grind the ball blank in the precision grinding machine to achieve the required precision and smoothness of the finished product; Polishing cleaning: Place the balls in a polishing drum, rotate it, and clean the surface with polishing cleaning agents mixed with water to make the surface clean and bright; 8. Appearance selection: Manually inspect the surface of the steel balls for any defects, measure the true roundness, batch diameter variation, and detect the surface roughness using a surface roughness meter as the final inspection; 9. Packaging: Apply rust-proof oil to the steel balls/stainless steel balls/steel ball bearings, then pack them into boxes or burlap bags and seal them.
