Production process of stainless steel spheres
The production process of stainless steel spheres is unknown to most people. Today, we will talk about the production process of stainless steel spheres, which is one of our highlights.
1、 Simple production process of steel balls
Ball blank forming → ring removal → rough grinding → soft grinding → heat treatment → ball blank forming → smooth ball (or filing → soft grinding) → hard grinding → fine grinding → precision grinding (or polishing) → ultra precision grinding.
2、 Detailed production process of steel balls
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.
