grinding down on the grinder, the curvature is correct, how to verify that? Please know that there is the point one or two, thank you.
1) generally use the outline instrument to report out to judge, and now the bearing factory basically use this method, more efficient and accurate2) with three methods to judge, but the premise to do a product like the circle of curvature and as like as two peas. Then the measured raceway selected three different heights, to measure their radial dimensions, and then circle than (because the circle is kind and requirements for the product of the so-called three points as like as two peas). Determine a circle.
