为了生产用于复杂的长扁平部件的预成型件，可以使用沿着纵向轴线的不稳定质量分布的轧制工艺，如楔横轧。用于楔横轧工艺的工具可以构造为辊或平的，两者都具有楔。在合作研究项目SFB 489“生产精密锻造高性能零件的工艺链”中，子项目“精密锻造的创新机床和工具技术”涉及开发带销和法兰的双缸曲轴的无飞边锻造工艺。该工艺由IPH -汉诺威集成生产研究所开发。开发的锻造序列的第一个预成型件是通过基于带楔的平板的楔横轧工艺生产的。为了考虑轧制过程中预成型件中两缸曲轴的质量分布，需要曲柄臂的四个质量集中以及销和凸缘的质量集中。
To produce preforms for complex long flat parts with an unsteady mass distribution along the longitudinal axis rolling processes, like cross wedge rolling, can be used. Tools for cross wedge rolling processes can be constructed as roller or flat, both with wedges. In the collaborative research project SFB 489 “Process chain for the production of precision forged high performance parts” the subproject “Innovative machine and tool technology for precision forging” deals with the development of a flashless forging process for a two cylinder crankshaft with pin and flange. This process is developed by IPH – Institut für Integrierte Produktion Hannover. The first preform of the developed forging sequence is produced by a cross wedge rolling process on the basis of flat with wedges. To consider the mass distribution of the two cylinder crankshaft in the preform for a rolling process four mass concentrations for the crank arms and mass concentrations for pin and flange are needed.
