Manufacturing ball bearings is surprisingly similar to forming balls of dough. A supply of metal wire approximately the same diameter as the ball bearings is placed in a machine with two plates designed as hemispheres. When the two halves are brought together forcefully, a rough metal ball is formed. The problem is, some additional metal shards called flashing still remain. The ball bearings are then placed in another machine which removes the flashing to create a perfect state of roundness.

Following the above, I believe the final grinding / polishing stage is completed by the ball bearing being ground between two parallel plates.

Ball or needle roller bearings are hardened metal which is ground by special grindings machines. If you go to Sweden visit SKF which is a bearing manufacturing company.

They start off roughly round then are ground down by a centre-less grinding process that takes them down in size and improves the finish until they are perfectly round then fine grinding and sizing. Its a very automated process

They start off a lumps of metal and are sucked by really hard looking skinheads until they are worn in to a perfect sphere ready for use in high tolerance heavy duty applications.
Alright I'm a liar, I just wanted to feel useful for once............
