Other forging machines

A special feature of cross rolling is the axial feed cross rolling. The axial feed cross roll is used to preform small quantities of billets to special geometries. The round material is actively drawn through two forming rollers. The diameter reduction is achieved by radial adjustment of the forming rollers.

The cross wedge roll is designed for the preforming of round material and is ideally suited for the finish-forming of e. g. gear shafts, stepped as well as hollow shafts. The QKW can be used both as a stand-alone unit and as an integral part of an automated forging line.

LASCO manufactures electric upsetting machines in horizontal and vertical arrangement in special constructions, however not in fixed type series, but adapted to special market and customer requirements. The application of the electric upsetting process circumvents certain technological limits of mechanical upsetting machines ? economic efficiency increases. All commercially available steels and non-ferrous metals including high-temperature nickel alloys can be upset in the electric upsetting process.

The forging roll is designed for preforming round and square material. The billet is fed radially into the rollers by a manipulator and preformed in individual sectors (mostly 2 to 5 passes).

The skew rolling mill is used to produce preforms for weldless tubes. Starting from round material, a reverse extrusion operation is first carried out with a hydraulic press. The preformed billet is then threaded horizontally onto the mandrel of the skew rolling mill. In the subsequent forming process, the wall thickness of the tube billet is gradually reduced using several active rollers.
