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.
