Description

Cutter wheel for cutting glass material

The invention relates to a cutter wheel for cutting a glass material.

Background technique

With the rapid development of technology, many fields require thinner glass, higher hardness, and higher requirements for glass cutting quality. The following is an example of the glass material used in liquid crystal displays.

The disc-shaped cutter wheels used for glass cutting have the common features of: the cutting edge portion, the cutter wheel surface, and the shaft hole of the cutter wheel center for mounting the cutter shaft. The cutting edge is V-shaped, which is easy to cut into the glass. The material of the cutter wheel is mainly diamond, polycrystalline or polycrystalline diamond, and hard alloy material.

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 getting larger and larger. At the same time, the quality requirements of the glass cracked section are also higher, so that the pressure, cutting technique, cracking efficiency and the like during cutting are required. The accuracy requirements are also higher, which poses a great challenge to the research and development of the cutting tool-knife wheel.

Patent Z01124992.7 and CN200680003956.0, and the patent Z200410104603.2 of the applicant's application, etc., propose several microstructures processed at the cutting edge portion, each of which causes periodic irregular grooves in the cutting edge portion. . The principle of cutting the glass material is: Applying a certain pressure to the cutter wheel during cutting so that the convex portion of the blade is cut into the interior of the glass, and the concave portion cannot be cut into the interior of the glass, thereby forming intermittent periodic cuts. Adjacent cuts can produce cracks under stress and are connected by split lines, causing the glass to be cut and broken.

However, when the cutter wheels of these structures are used to cut the glass, the most important problem is that the cutter wheel will be filled with the glass micro-powder generated when the cutter wheel is cut, which causes the cutter wheel to be blocked by the microstructure, which causes the cutter wheel to lose the cutting ability; The location of the structure that is in contact with the glass can cause severe damage to the crack created by the cut. In view of the above problems, the present invention provides a cutter wheel for cutting glass and other glass materials, and the cutter wheel of the new structure can prevent clogging and avoid scratching the glass and avoid breaking the crack, and A high cutting quality can be obtained.
