Shearing machine for metal in the form of sheet and plae is of the pivoted arm type, with cutting blades seated in straight, flat machined beds to reduce fitting and adjusting time. The lower cutting blade (2) does not move, being fixed to the base frame (1) of the machine. The upper blade (4) moves with the pivoting arms (3) to provide the cutting stroke and is inclined at an angle (alpha) to the lower blade. This angle is bisected by a flat, horizontal plane (P) passing through the centre of the pivot (AB) and is approximately perpendicular to a vertical plane formed by the cutting edges (6, 7) of the blades.
