3/16 Inch AISI 440c for Bearing Stainless Steel Ball
1. Raw Material
2. Drawing--Drawn the wire rod to the required size, in closer tolerances so that it can be used in next step cold heading. 
3. Heading--Ball blanks are cold or hot headed from rolls of wire or bar stock depending on their size and the material.It cuts to length and the width a small percentage larger than the width of the finished ball.The wire or rod is then fed through a header.This cold forged process produces "slugs" at an incredibly high speed.These rough shaped balls have a ring around the middle.The next process is to remove this ring. 
4. Flashing--To remove the "ring" around the ball, the slugs are then flashed.The flashing gives the ball a rough finish. 
5. Heat Treatment--Heat treatment, where necessary, gives the balls the maximum possible hardness and the best technical characteristics that can be achieved with the materials used. 
6. Grinding--After the ball is heat treated, the ball is then ground to the approximate diameter of the finished ball.
7. Sorting--Sorting the right size ones, and the qualified steel balls are filtered.
8. Lapping--The lapping will be processed after the ball is ground to approximate size. This lapping process polishes the ball to the exact required size and it makes the ball shiny. 
9. Inspection--The balls need to be inspected by mechanically and visually after lapping process.The balls are measured through a fine tuned tapered roller. The workers will also do the visually checking before packing.
