Instead, centerless grinders are used for grinding very long pieces. The piece is hold by a dedicated support, while it will be subject to the simultaneous work of two wheels positioned on oblique axes to each other. Thanks to the different positioning of the two axes, the progress of the bar will be generated during processing.

Form milling is the operation of producing irregular contours by using form cutters. The irregular shape may be convex, concave, or of any other shape. After machining, the formed surface is inspected by a template gauge. The cutting rate for form milling is 20% to 30% less than that of plain milling.
[5] Autogenous mill Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles.
