Manufacturing Process of Steel Ball1. Raw Material
2. Drawing--Drawn the wire rod to the required size, in closer tolerances so that it can be used in next stepcold heading.
3. Heading--Ball blanks are cold or hot headed from rolls of wire or bar stock depending on their size and thematerial.It cuts to length and the width a small percentage larger than the width of the finishedball.The wire or rod is then fed through a header.This cold forged process produces "slugs" atan incredibly high speed.These rough shaped balls have a ring around the middle.The nextprocess is to remove this ring.
4. Flashing--To remove the "ring" around the ball, the slugs are then flashed.The flashing gives the ball arough finish.
5. Heat Treatment--Heat treatment, where necessary, gives the balls the maximum possible hardness and the besttechnical 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 finishedball.
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 processpolishes 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 aremeasured through a fine tuned tapered roller. The workers will also do the visually checkingbefore packing.
