The paper focuses on the manufacturing of a hybrid carousel disc for an indexing gearbox, developed to reduce the mechanism mass and improve its dynamic performance. It describes the manufacturing chain, including composite material definition, the design and fabrication of a mould from tooling board, and compression moulding technology. Furthermore, the study analyses technological aspects of machining abrasive GFRP/CFRP materials, including the selection of cutting conditions and tools, and the integration of steel inserts, which requires precise surface preparation and verification of adhesive bond quality. The work refers to FEA results for mass moment of inertia and natural frequencies as the basis for validating the proposed manufacturing solution. The presented know-how demonstrates the technological feasibility of the hybrid concept and provides a foundation for subsequent operational testing and patent- protected implementation.
