Production process

1) Heading

The wire section is headed in a concave, spherical die using a high-speed automatic forging press.

2) Flashing

Headed blanks are roughly ground during high-pressure rotation in the grooves of the discs made of special cast iron.

3) Heat treatment

The balls are annealed and cooled during quenching with a fully controlled automatic furnace.

4) Grinding

The balls are ground and lapped to the final dimension and required surface appearance.

5) Washing

The balls are washed to get rid of dirt, dust and filings from their surface.

6) Visual Inspection

All balls are 100% inspected by automatic visual inspection machines.

7) Packing

The balls are packed in a convenient way for future shipment.
