Product Description
9mm steel ball with threaded hole
1. Raw material: a ball starts in wire or rod form.
2. Heading: In the first step, heading machines cut wire into short lengths and form
it into spherical shapes between dies.
3. Flashing: A process that gives a ball blank a rough finish and removes the excess
material around the ball.
4. Heat-treating: Harden the balls by subjecting a metal or alloy to controlled heating
and cooling to improve hardness and other properties.
5. Hard Grinding: Slow, meticulous grinding assures proper sizing and sphericity.
6. Lapping: This process has two steps, first is simple lapping, then is fine grinding.
Both of them is to polish the balls to a shiny finish and to the exact size required by ISO 3290 Grade.
7. Clean: First, clean the surface of balls; then use the dehydrated oil to dry off the balls; the last step is applying antirust oil for the balls. When these steps have done, each ball will be selected by machine or naked eye to make sure every ball is perfect.
8. Inspection: Each batch of products will accept measurement and inspection by the special inspectors, to check whether the products consistent with the customer's requirement.
