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.
