Claims

[Claims for Utility Model Registration] 1. A cutter with a cutting edge protruding from the approximate center of its outer periphery, supporting parts integrally protruding from both sides in the axial direction, and whose axis is oriented substantially horizontally. The cutting edge of this cutter is made to protrude downward from the lower end of the cutter holder on a bearing provided on the lower end side of the cutter holder with supporting parts on both sides of the cutter located on the outside of both sides of the cutter. A tapered shaft-shaped engagement convex part provided on one side of the bearing part of the cutter holder, the outer diameter of which is smaller on the distal end side than the proximal end side, is larger than the tip angle of the tapered shaft-like engagement convex part provided on the other side. A cutter head for a glass cutting machine that is rotatably engaged and supported in a tapered hole-shaped engagement recess with a small opening angle. 2. A cutter having a substantially disc-shaped cutter wheel with a cutting edge protruding from the approximate center of its outer periphery, and a shaft-shaped support portion integrally protruding from both sides in the axial direction, and whose axis is oriented substantially horizontally. The supporting parts on both sides of the cutter are attached to the bearings provided on the lower end side of the cutter holder, which is located on the outside of both sides of the cutter. A tapered shaft-shaped engagement convex part is provided on one of the tip of the cutter holder and the bearing part of the cutter holder, and the outer diameter of the distal side is smaller than that of the proximal end. A cutter head for a glass cutting machine that is rotatably engaged and pivotally supported in a tapered hole-shaped engagement recess whose opening angle is smaller than the opening angle. 3 A tapered shaft-shaped engagement protrusion is provided at the tip of the shaft-shaped support part on both sides of the cutter, and a bearing part provided on the lower end side of the cutter holder located on the outside of both sides of the cutter is engaged with this engagement protrusion. A cutter head for a glass cutting machine as claimed in claim 2, which is a registered utility model and is provided with an engaging recess in the shape of a tapered hole for engagement, and the cutter is rotatably supported on a cutter holder. 4. Adjust the tip angle of the tapered shaft-shaped engagement convex part to 50~
70 degrees, and the opening angle of the tapered hole-shaped engagement recess is about 20' smaller than the tip angle of the engagement protrusion. Cutter head for glass cutting machine. 5. A cutter head for a glass cutting machine according to claims 1 to 4, wherein the cutter is integrally formed from cemented carbide. 6. A cutter head for a glass cutting machine according to claims 1 to 4, wherein the cutter is integrally formed from sintered diamond. 7. A cutter head for a glass cutting machine as set forth in claims 1 to 6 of the utility model registration claim, wherein the inner surface of the tapered hole-shaped engagement recess is mirror-finished.
