Advanced Grinding Approach for Toroidal Worms Based on Five-Axis Machining with Disc-End Mills

In the field of high-precision gear manufacturing, toroidal worms have gained significant attention due to their compact design, smooth transmission performance, and high load-bearing capacity. However, the complex geometry of toroidal worms poses substantial challenges for conventional machining and grinding techniques. To address these challenges, a novel grinding approach has been developed based on five-axis machining technology using disc-end mills. This approach integrates an internal spindle grinding head and a tilted grinding wheel support structure, offering enhanced accuracy, flexibility, and efficiency in the production of toroidal worms.
