To make balls the easy way: Start with a pole of steel, and cut off little pieces somewhat bigger than the volume of the ball. At that point continuously produce them marginally round with little bites the dust, at that point move them through 2 equal plates, one of which has a winding depression cut on its work surface. Consider two circles squeezed together turning inverse, similar to the winding recordings that should make you discombobulated, for one plate, the other only a level plate maybe with some rough finished surface. These plates begin at a marginally more prominent division, however as they winding towards the middle they close into the measurement of the ball. The balls are stacked outwardly, the top plate is turning, the balls move towards the middle and drop out at the inside truly round. This machine made balls for Ford power seats at one manufacturing plant I went to. Sooner or later, heat treat for hardness. At that point put balls into a vibratory cleaning machine. This machine utilizes stones, water, and coarseness while vibrating vigorously, most likely for a long time. In the end, the balls get truly round. Expel the balls. Measure them at rapid and sort them out by size. One basic test is dropping the balls onto a tilted metal plate where they bob off into a little opening in the divider. Ones that miss are dismissed. One can pick 100 balls all inside one-millionth of an inch, sell that as and super prescise set. Select thousands inside .00001 up to .at least 0002 and sell those for junky buyer garbage, made to be modest garbage. With balls, one gets the procedure to rehash, at that point sort out the balls to choose the ones that turned out right to the ideal size inside progressively bigger resiliences, less precise will sell for less cash, and arrange or procedure to littler size the rejects. To put it plainly, one makes a great many balls taking a stab at a given size, at that point choosing the balls that turned out right available to be purchased.
