Product Description
Steel balls are divided into grinding steel balls, forged steel balls and cast steel balls according to the production and processing technology. According to the processing materials, they are divided into bearing steel balls, stainless steel balls, carbon steel balls, copper bearing steel balls, alloy balls, etc. Among them, bearing steel balls are important basic components in industry. Alloy steel balls are made of carbon, chromium, manganese, molybdenum, etc. as the main added metal elements, and are produced by forging, spinning, rolling and casting. The shaped iron alloy wear-resistant body is the most important component of today's crushing industrial mining balls and cement balls.

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.
1. Q:Is it in stock?
