This edition of the series of programs explaining the technology used to produce items that are familiar in our daily life features ‘Steel Balls’. A bicycle wheel spins smoothly because the wheel axle contains ball bearings. The steel balls inside the ball bearing must be close to perfectly spherical. The program introduces the production method of high-precision steel balls with a margin of error of less than 0.1 micrometers.

      This is a very good video. The full speed and then slo-mo to stills is very easy to follow. I always wondered how they made those critters!

      Fun. And it is interesting to know the steps, and the names of the different machines. What is going on inside the machines, however, is not really explained and that is a missed opportunity. There are exceptions. How the machine that initially presses a cylinder cut from a wire into a shape that is approximately spherical is well shown. The others, not so much. You see that a ball goes into a machine and comes out different, but what happens inside is not clear.

      Who was the brilliant mind that invented this complex machine to make Ball Bearings. I am sure it evolved over time and was trial and error and working progress like most machine tools that are the foundation of all manufacturing. Amazing process and an informative and well done teaching video.

      I always wonder that myself.. The end product is no big deal....but getting to the end product is fantastic and the inventor of the machine must be brilliant
