Axial feed cross roll

AVQ


The axial feed cross roll
complements the range of rolling machines. In contrast to cross wedge rolling and roll forging the tool geometry of the AVQ is not product-dependent.

The method is particularly suitable for the production of rotationally- symmetrical pre- and finish-forms, especially if flexibility is required.

The reduction of the unformed blanks in sections is effected by two radially advanced rotating disks (tools). At the same time the work-piece is axially pulled through the roller gap by tongs that grip the blank end.

The program-controlled movements of radial feed (tool) and axial feed (blank) produce the desired steps of the blank.

Special features:

•    Independent of work-piece
•    Low tool costs
•    Optimally suited for small batch sizes
