Polishing Tool, Polishing System And Method Of Polishing

A polishing tool for spectacle lens surface machining comprises a tool body rotatably supported about a rotational axis. The tool body features a polishing surface at a first axial end, which is axially bulged convexly or concavely to polish an optical surface. An axial channel extends through the tool body from an inlet at a second axial end to an outlet at the first axial end to supply a polishing agent. The polishing surface is characterized by at least one groove extending radially from the outlet to the surface perimeter, facilitating the distribution of the polishing agent across the polishing surface. The tool may be integrated into a system comprising a supply unit, lens support, and drive unit.
