In this section the surface of the cast metal is treated with turning operation in which the surface irregularities have been removed. It is done using lathe machine, in which the cast part is attached to the working holding device which is the cylindrical wooden block attached to the head stock of the lathe. The wooden block is customized into required shaped based on the type of product to be finished. The tail stock of the lathe is used to support the product, after fixing the cast metal the turning operation is carried out during which the surface is smoothened and polished.
