Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached ...

Puddling (metallurgy) - Wikipedia

Cast iron was used extensively in 19th-century public spaces for everything from park benches and lamp posts to railway stations and band stands. The vulnerability to corrosion of this exposed ironwork meant that protective coatings (usually lead-based oil paint) were paramount. This article looks at the maintenance and repair of coatings for outdoor historic cast iron with a detailed case ...

Milling Process, Defects, Equipment

The process begins by preparing the puddling furnace. This involves bringing the furnace to a low temperature and then fettling it. Fettling is the process of painting the grate and walls around it with iron oxides, typically hematite; this acts as a protective coating keeping the melted metal from burning through the furnace. Sometimes finely pounded cinder was used instead of hematite.

Production of grey cast iron powder via target jet milling

A passive layer, often an oxide, can be hard on tool bits during machining. Pickling vs. passivation of stainless steel. The passivation of steel is a process that uses an acid bath to leave behind an oxide layer. Pickling is another acid-bath treatment, but it has the opposite goal: pickling uses an acid to clean oxides from the surface of the ...

Cast iron begins its life as pig iron, which is remelted and often combined with large amounts of scrap iron and sometimes with steel. Contaminants are removed from the melted pig iron, and the iron, once melted, is then cast. Casting is the process of pouring the iron into a mold thus giving it a shape.
