A complete set of production processes for solid steel balls

- Aug 11, 2018-

The solid steel ball is the most important part of the bearing and the most used rolling object in the bearing industry. Its quality directly affects the quality of the bearing. Since the solid steel ball is mostly used for moving parts, it requires more reliable quality to ensure the normal operation of the machine, so it uses special metal materials such as stainless steel, copper, aluminum and titanium alloy.


Solid steel balls are widely used in hardware, electronics, iron, machinery, power, mining, metallurgy and other industries. The first step in producing a solid steel ball is to stretch the wire, which is to draw the wire to the required wire diameter by a wire drawing machine; then put the drawn wire into a steel ball cold heading machine and beat it into a steel mold in the machine. Ball embryo; two cast iron grinding balls in the ball machine pressurize the cold ball embryo to remove the outer band and the two poles on the ball.


Two cast iron grinding balls in the soft ball machine honing the ball of the photosphere to make the ball embryos into the required ball diameter and surface roughness; loading the ball into the heat treatment furnace for carburizing, quenching and tempering the ball It has a certain carburizing layer and hardness, toughness and crushing load, which is the heat treatment of solid steel balls.


The ball is then finely ground to achieve the precision and finish required for the finished product; finally, the ball is poured into a polishing drum and rotated with a polishing detergent to clean the surface. After the production is completed, it is necessary to check the quality of the solid steel ball, measure the diameter of the steel ball with a micrometer, and then package it for sale after the inspection.
