Bearing steel balls
Bearing steel balls are a type of component used in industrial production. Belonging to a part of bearings.
Production process
1. Wire drawing: Stretch the wire to the desired diameter using a wire drawing machine;
2. Cold heading (forging): Place the pulled wire into a steel ball cold heading machine, and use the steel die inside the machine to forge it into a ball blank;
3. Lightball: Two cast iron grinding ball circular plates inside the lightball machine press and file the cold heading embryo to remove the outer ring and two poles on the embryo;
4. Soft ball: Two cast iron grinding ball circular plates inside the soft ball machine file the light ball embryo to grind it into the required ball diameter and surface roughness;
5. Heat treatment: Put the ball into a heat treatment furnace, carburizing it, quenching it, and tempering it to give it a certain carburizing layer, hardness, toughness, and crushing load;
6. Hard grinding: The grinding wheel disc inside the grinding machine pressurizes and grinds the heat-treated ball blank to remove the black oxide layer on the surface of the ball and correct the accuracy of the ball;
7. Precision grinding/polishing cleaning: Precision grinding: Grind the grinding ball embryo in the precision grinding machine to achieve the required precision and smoothness of the finished product; Polishing and cleaning: Pour the ball into the polishing drum and rotate it, then clean the spherical surface with polishing cleaning agent and water to make it clean and shiny;
8. Appearance selection: Use manual visual inspection to check for any defects on the surface of the steel ball, and use a micrometer to measure the true roundness, batch diameter variation, and use a surface roughness meter to detect surface roughness as the final inspection;
9. Packaging: Coat steel balls/stainless steel balls/bearing steel balls with anti rust oil and pack them in cardboard boxes or woven bags.
10. Shipping: Packaging and shipping should be carried out according to customer requirements.
