Manufacture process of steel balls | ||||
Step 1 Heading | Balls blanks are cold headed from rolls of wire. | |||
Step 2 Flashing | Rolling balls between two hard alloy plates to removes the slight band and small protrusions. | |||
Step 3 Heat treat | Heating balls to a high temperature in furnace and quenching balls in a liquid bath. | |||
Step 4 Rough grind | Rolling balls between the face of a fixed iron plate and a very hard fire-grit grinding wheel. Then rolled the hardened ground balls between two cast iron plates. | |||
Step 5 Cleaning | The final production operation cleans the finished balls and adds a shiny luster. | |||
Step 6 Final Inspection | Balls are gauged, visually inspected and subjected to other quality tests to insure every customer's specifications are achieved. | |||
Step 7 Packaging | The balls are packaged in accordance with customer specifications for shipping. | |||
Material | Carbon, Chrome, Stainless, Aluminium, Copper, Brass and so on. |
