The planer is a machine tool designed to produce plane and flat surface on a work piece which is too large or too heavy. It uses linear relative motion. Planer machine is large and heavy in weight. The work piece is securely fixed on a table called platen, and it reciprocates horizontally against a single edged cutting tool. The surface machined may be horizontal, vertical or at an angle
