Problems solved by technology
[0006] However, when cutting glass with these types of cutter wheels, the main problem is that the cutter wheel will be filled with glass powder produced during cutting, causing the microstructure of the cutter wheel to be blocked, causing the cutter wheel to lose its cutting ability; Parts of the structure that come into contact with the glass can wreak havoc on the cracks created by the cut

Embodiment Construction
[0058] Combine below Figure 1(a) , 1(b) , 1(c), 1(d) and 1(e) describe in detail an embodiment of a cutter wheel for cutting glass material (first cutter wheel) according to the present invention.
[0059] The invention provides a disc-shaped cutter wheel capable of cutting glass materials, especially glass materials with a thickness of 0.03 mm to 2 mm, which is mainly obtained by processing a special microstructure at the V-shaped cutting edge of a commonly used disc-shaped cutter wheel A cutter wheel with a new structure.
[0060] Among them, the V-shaped disc cutter wheel has a first curved surface a 1 and the second surface a 2 And the V-shaped cutting edge portion 1 formed by the edge ridgeline, the first curved surface a in this embodiment 1 and the second surface a 2plane respectively. The cutter wheel disk surface 2 and the cutter wheel center are used to fix the shaft hole 3 of the cutter wheel. The material of the cutter wheel is polycrystalline or polycrystal...

Abstract
A cutter wheel for cutting glass material comprises a V-shaped cutting blade (1) with an angle of ?1 formed by the first curved surface a1, the second curved surface a2 and outer edge line l, a circular disc surface (2) and a central axle hole (3). Cutting blade (4) and groove structure (5) are distributed alternately at the outer edge line l of the V-shaped cutting blade (1), and the alternately-distributed cutting blades (4) form the first layer of cutting edge. The groove structures (5) consists of the third curved surface a3 and the forth curved surface a4 which are concave, and the third curved surface a3 intersects the forth curved surface a4 at a curved line segment l1. The third curved surface a3, the forth curved surface a4 and the curved line segment l1 form the second layer of V-shaped cutting edge. The curved line segment l1 is a concave one, and both ends of the concave curved line segment are tips of the adjacent cutting edge. The cutter wheel can avoid such problems that the cutter wheel is blocked, the glass is damaged and crack line is broken, and can cut glass with high quality.
Description
technical field [0001] The invention relates to a cutter wheel for cutting glass material. Background technique [0002] With the rapid development of science and technology, many fields require glass to be thinner and harder, and the requirements for glass cutting quality are getting higher and higher. The following is an example of glass materials used in liquid crystal displays. [0003] The disc-shaped cutter wheels used for glass cutting have a common feature: they all include a cutting edge, a disc surface of the cutter wheel and an axis hole for installing a cutter shaft in the center of the cutter wheel. Among them, the cutting edge is V-shaped, which is convenient for cutting into the glass. The material of the cutter wheel is mainly diamond, polycrystalline or polycrystalline diamond, and hard alloy materials. [0004] At present, the thickness of the glass used in liquid crystal displays is getting thinner and thinner from 2mm to 0.1mm, and the hardness is gettin...
