Latest Patents

Ota’s listed patents address tool durability, chip control, and manufacturing considerations.

- **Roughing end mill.** This invention uses axially undulating cutting edges with offset wave phases, coated flank faces, and alternating rough and smooth surface regions near the cutting edges. These features are designed to guide chips and help prevent damage to the flank faces and cutting edges when chips enter the gap between a tool and the work surface.

- **Replaceable machining head.** This design features a coated head body and limits the number of convex droplets or macroparticles on the coating over the tool-attachment faces. The stated goals include reducing fractures and production costs, extending tool life, and preventing the head body from falling off during replacement.
