Analysis and Control of Factors Influencing the Life of Bearing Steel Balls
Simple production process for bearing steel balls
Green forming removal ring, rough grinding, soft grinding, heat treatment, green forming light ball (or file soft grinding), hard grinding, fine grinding, fine grinding, and ultra precision grinding.
Detailed production process of bearing steel balls
1. Drawing: Use a drawing machine to stretch the wire to the desired diameter;
2. Cold heading (forging): Put the pulling wire into the steel ball for cold heading, and use the internal steel mold to form the ball blank through forging;
3. Lightball: Two cast iron grinding ball circular plates are used in the lightball machine to apply pressure and file to the cold heading ball embryo, removing the outer ring and bipolar points on the ball embryo;
4. Soft ball: Two cast iron grinding ball circular plates inside the soft ball machine are worn down with a smooth ball embryo file to achieve the required ball diameter and surface roughness of the ball embryo;
5. Heat treatment: Put the ball into a heat treatment furnace for carburization, quenching and tempering to give the ball a certain carburizing layer, hardness, toughness, and crushing load;
6. Hard grinding: The grinding wheel disc inside the grinder is pressurized to grind the heat treated ball embryo, 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 ground ball embryo in a precision grinding machine to achieve the required precision and glossiness of the finished product; Grinding and cleaning: Put the ball into the grinding bucket and rotate it. Clean it with grinding cleaning agent and water to make the spherical surface bright and clean;
8. Appearance screening: Manually visually inspect the surface of the steel ball for scratches, measure roundness with a micrometer, and check surface roughness using a batch diameter change and surface roughness meter;
9. Packaging: Steel balls/stainless steel balls/bearing steel balls coated with rust proof oil are placed in cardboard boxes or woven bags for packaging.
I believe that through the short description, everyone has gained a general understanding of the production process of bearing steel balls. Bearing steel balls play a very important role in industrial development and national economic development. In order to meet different work needs, special material steel balls are also widely used in various fields, such as ceramic balls, glass balls, 3Cr13 stainless steel balls, titanium alloy steel balls, etc. The popularization of these special material steel balls has greatly promoted the development of the steel ball industry.
