Lead Acid Battery Manufacture 3 · In the milling process,solid lead (which may range in size from small balls to complete pigs) is fed into a rotating mill.The tumbling action of the lead generates heat and the surface of the lead oxidizes.As the particles roll around in the drum,the surface layers of oxide are removed to expose more clean lead for oxidation. Milling (machining) Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.This may be done varying direction on one or several axes,cutter head speed,and pressure.Milling covers a wide variety of different operations and machines,on scales from small individual parts to large,heavy duty gang milling operations. Tinning The pack mill process.The pack mill process begins with a tin bar,which is a drawn flat bar that was usually purchased from an ironworks or steel works.The tin bar could be wrought iron or mild steel.The cross section of the bar needed to be accurate in size as this dictates the length and thickness of the final plates.
