Grinding and fine finishing of future automotive powertrain components

TLDR

The automotive industry is transforming under regulatory pressure and rapid electrification. The study reviews the state of the art in grinding, dressing, texturing, and fine‑finishing technologies for powertrain components. Authors conduct a critical analysis of technological trends and requirements for major powertrain components in collaboration with OEMs, suppliers, and machine builders, surveying research papers, patents, and case studies to illuminate the production value chain. Key industrial and research challenges in grinding and fine finishing are identified and summarized.

Abstract

The automotive industry is undergoing a major transformation driven by regulations and a fast-paced electrification. A critical analysis of technological trends and associated requirements for major automotive powertrain components is carried out in close collaboration with industry – covering the perspectives of OEMs, suppliers, and machine builders. The main focus is to review the state of the art with regard to grinding, dressing, texturing and fine-finishing technologies. A survey of research papers and patents is accompanied by case studies that provide further insights into the production value chain. Finally, key industrial and research challenges are summarized.
