Step - 1: Wire coils are checked for diameter and chemical composition.
Step - 2: Wires are then cold forged into spherical shapes blanks by heading machines.
Step - 3: Headed blanks are ground inside grooved metal disks at very high pressure in flashing machines.
Step - 4: Specially designed furnaces are used to hardened steel balls. The Balls are then quenched and tempered to give them sufficient strength & durability.
Step - 5: Similar to flashing process, Grinding is done using grinding stone disk for perfecting the sizes, spherical shape and smooth surface finish in grinding machines
Step - 6: Lapping of steel balls is done using Bakelite disk/lapping disk to achieve more accuracy in sizes, spherical shape and smooth surface finish of steel balls.
Step - 7: Ball Washing is done to clean surface thoroughly.
Step - 8: Sorting of steel balls in automatic sorting machine to sort different gauges and then steel balls are checked for surface defects.
Step - 9: Further quality reports are made by quality department as per general standards/customer specific standards in the form of diameter, hardness, roundness, roughness & visual.
Last Step: Using anti corrosive oil, steel balls are packed in cardboard boxes & shipped to customer.
