Hollow Ball Bearings, EDM And Injection Moldmaking?
Apparently the "chips" from EDMing resemble hollow ball bearings, except that they are only mostly round, and one part is very jagged. It does sound like a Russian type of experiment, who knows? Like a lot of inventions, there were simultaneous developments in the USA, which led to a machine that was made to remove broken taps and drills.

Ball Milling - an overview | ScienceDirect Topics
Ball milling is another technique which was reported very recently for the production of NFC. In this method, a cellulose suspension is placed in a hollow cylindrical container, partially filled with balls (e.g., ceramic, zirconia, or metal). While the container rotates, cellulose is disintegrated by the high energy collision between the balls.
