A part’s mechanical life span significantly depends on its microstructure, residual stress state and material hardness. Current research shows that the mechanical surface-strengthening process of deep-rolling is a suitable method for the alteration of surface and subsurface properties with the aim of increasing strength and life span of highly stressed components. Further increase in the mechanical life span can be reached using the turning process temperature while deep-rolling. For this purpose, a turn-rolling tool has been developed. Especially concerning soft machining operations, the induced process temperatures lead to higher degrees of plastic deformation in the subsurface of the material. This results in lower surface roughness, higher hardness and an optimal residual stress state. Furthermore, the turn-rolling process leads to positive properties regarding the part’s microstructure because of the increased elastic and plastic deformations in the subsurface thanks to the combination of thermo-mechanical interactions within the material.

零件的机械寿命在很大程度上取决于其微观结构，残余应力状态和材料硬度。当前的研究表明，深轧的机械表面强化工艺是改变表面和亚表面性能的合适方法，目的是提高高应力部件的强度和寿命。在深轧时使用车削过程温度可以进一步提高机械寿命。为此目的，已经开发了一种车削工具。特别是对于软加工操作，所引起的过程温度导致材料表面下的塑性变形程度更高。这导致较低的表面粗糙度，较高的硬度和最佳的残余应力状态。此外，
