Brief Introduction

Miniature balls are those that are less than 1/8” (3 mm) in diameter. 

Some of their key applications include instrumentation for calibration and 

switching, microvalves, pumps, medical and dental equipment, optical 

devices, ball screws, timepieces, metal detectors, disk drives, and pens. 

How Miniature Balls Are Made

Heading- Flashing- Heattreatment- Grinding- Find Grinding- First Lapping- Second Lapping

As the name implies, miniature steel balls are smaller than 3/16" diameter are considered miniature. Miniature balls are produced by totally different methods than commercial bearing balls. These processes are so totally unique that during World War II, the Allies were unable to master the process. All of the miniature balls made by the Allies were made by grinding down conventionally produced commercial balls to the small diameters required.
