Steel balls are a common mechanical component widely used in various industrial fields. According to the application and shape of steel balls, they can be divided into the following categories:
           1. Abrasive steel ball: This type of steel ball is mainly used for grinding and grinding, and usually has high hardness and wear resistance. It has a variety of shapes, including flat, spherical, polygonal, etc., with high surface smoothness, which can ensure grinding quality and efficiency.
           2. Forged steel balls: Forged steel balls are mainly used for forging and crushing, and are generally made of carbon structural steel or alloy structural steel. Its shape is spherical or oblate, with a high surface smoothness and the ability to withstand high impact loads and high temperatures.
           3. Grinding steel balls: Grinding steel balls are mainly used for grinding and polishing, usually made of high carbon steel or alloy steel. Its shape is spherical or flat spherical, with a high surface smoothness, which can ensure the quality and efficiency of grinding and polishing.
           4. Cage steel ball: Cage steel ball is mainly used inside the cage of mechanical equipment, usually made of medium carbon steel or alloy structural steel. Its shape is spherical or flat spherical, with a high surface smoothness, which can ensure the stability and accuracy of mechanical equipment.
           5. Steel balls for bearings: Steel balls for bearings are mainly used in various types of bearings, usually made of high carbon steel or alloy structural steel. Its shape is circular or polygonal, with a high surface smoothness, which can ensure the accuracy and service life of the bearing.
           In summary, steel balls can be classified into various types based on their different applications and shapes. Different types of steel balls have different characteristics and application ranges, and need to be selected according to specific usage needs.
