One,Stainless Steel BearingsThe simple production process of steel balls includes: blank forming → de-coring → coarse grinding → soft grinding → heat treatment → blank forming → polished ball (or filing → soft grinding) → hard grinding → fine grinding → precision grinding (or polishing) → ultra-fine grinding.
Section II: Detailed Production Process of Steel Balls
1. Extrusion (Wire Drawing): Stretching wire material through a drawing machine to the desired wire diameter.
2. Cold heading (forging): Insert the drawn wire material into the steel ball cold heading machine, where it is shaped into a ball blank by the internal steel die.
3. The Light Sphere: The two cast iron grinding balls in the Light Sphere machine apply pressure to cold-forged ball blanks, smoothing off the outer ring and the two poles.
4. Softball: The two cast iron grinding balls within the softball machine grind the raw ball blanks to the required ball diameter and surface roughness.
5. Heat Treatment: The ball is placed in a heat treatment furnace, carbonized, quenched, and then tempered to achieve a certain carbonized layer, hardness, toughness, and crush load.
6. Grinding: The abrasive disc in the grinding machine applies pressure to the heat-treated ball billets, grinding off the black oxide layer on the ball surface and correcting the ball's accuracy.
7. Precision Grinding/Polishing Cleaning: Precision Grinding: The ball blanks are finely ground in a precision grinding machine to achieve the required precision and smoothness for the finished product; Polishing Cleaning: The balls are poured into a polishing drum, rotated, and cleaned with polishing cleaning agent and water to ensure a clean and shiny surface.
8. Appearance Selection: Manually inspect the steel ball surface for any defects and use a micrometer to measure true roundness, batch diameter variation, and employ a surface roughness gauge to check the surface roughness as the final inspection.
9. Packaging: After applying rust preventive oil to steel balls, stainless steel balls, or bearing steel balls, they are packaged in cardboard boxes or burlap bags.
