After the balls are removed from the lapping process the balls are inspected. This is done mechanically and visually. The balls are measured either through a fine tuned tapered roller or by a digital micrometer. These devices are capable of measuring within millionths of an inch. Once it is determined that the balls are within measured specifications, they are visually inspected through a high powered microscope. Once they are approved by quality control, the balls are then packaged and shipped to the customer.
