Planing treats the surface of a metal product. It is a convenient method for machining planar or vertical surfaces. It is perfectly suited for machining narrow long surfaces that cannot be machined in any other way.
Planing is also used for large castings and forgings. We know from practice that it is the most convenient procedure for adjusting a casting into the required shape. In such cases, planing is used for making grooves of various shapes and shaped surfaces.
Surfaces are planed to a smooth condition so that there is no risk of sharp edge cuts for workers or users. The geometrical accuracy is a notable advantage of planing.
