The process

The workpiece [1] prepared when a cylindrical piece is cut, flattened and a hole is made in the center. After heating the work piece is rotated between an inner [2] and the outer roller [3] and between two conical rolling pins [4]. The workpiece is compressed between the rollers such that its thickness in the radial direction decreases, but the workpiece volume is maintained throughout the process instead the diameter increases. Plan rolls has the task of ensuring that the workpiece upper and lower plane is maintained in parallel.
