Apparatus for machining the surface of an elongated rigid workpiece passing therethrough in a predetermined direction along a path. The apparatus includes at least one station having opposed tools for engaging opposite sides of the workpiece. The tools have tool axes extending generally perpendicular to the path. The tools are mounted for movement of their axes toward and away from the path, and for tilting movement of their axes relative to the path in a plane extending generally perpendicular to the path.

Machine for working metal surface

A straightening machine for straightening elongated workpieces at high speed comprises a plurality of stands or frames mounted on a machine bed displaceable with respect to each other in the direction of the movement of the workpieces. Each stand comprises a cage provided with a set of four straightening rolls rotatable about the axis. Each cage is mounted on a cage holder on a guide adjustable in radial direction with respect to the workpiece axis and the guides on the plurality of stands are located in parallel planes normal to the workpiece axis, with the guides on successive stands extending normal to each other as viewed in the direction of movement of the workpiece through the machine.
