Abstract: In the field of high-end customized manufacturing, the internal hole structures of components exhibit diversified forms, encompassing standard holes of varying sizes and shapes, as well as non-circular profile holes such as polygonal holes and keyway holes. Existing single-motor-driven equipment, constrained by serialized processing modes and insufficient flexibility, often leads to low efficiency and loss of precision control. To address this, this study proposes a parallelized internal hole finishing mechanism driven by a single motor, achieving the following breakthroughs. This is achieved by integrating a profiled trajectory groove in the form of a centrifugalelectromagnetic hybrid constant-pressure system for geometric adaptation, and a gear-based power-splitting transmission topology for synchronous operation. Consequently, the overall processing cycle is compressed to nearly the time consumption required for a single hole, significantly enhancing processing efficiency.
