A wheel cutter for cutting a flexible glass substrate, comprising:
- a first disk surface;
- a second disk surface disposed opposite to the first disk surface;
- a circumferential cutting edge formed by the first disk surface and the second disk surface extending outwardly and intersecting each other;
- a central shaft hole defined through central portions of the first disk surface and the second disk surface;
- and
- a hollow region formed by the first disk surface engaged with the second disk surface, the hollow region connected to the central shaft hole and configured to temporarily store flexible polymer scraps, wherein the hollow region is centrally symmetric;
- a plurality of holes distributed on the circumferential cutting edge, communicating with the hollow region, and configured to bring the flexible polymer scraps in the hollow region to store therein;
- wherein the hollow region has a tapered wall defined in each of the central portions of the first disk surface and the second disk surface and is configured to allow insertion of a cleaning device thereinto to clean an inside of the wheel cutter, and the tapered walls in the central portions are arranged symmetrically.
