Machining cast iron in a lathe or a mill. Cast iron, by its nature, can be very awkward to deal with. In the process of casting, when it is at a very high temperature in a liquid state, as the liquid is poured into a cool mould, then the sudden change in temperature of the contact surface causes the liquid iron to solidify very quickly, while the remainder of the iron cools more slowly.
