Problems solved by technology

Since diamond is very hard, the shape of the grinding material changes greatly, and it takes time to correct the grinding stone, etc., and it takes time to manufacture
[0010] This shows that the above-mentioned existing marking wheel obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem

Embodiment Construction

[0037] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation and structure of a scoring wheel and its manufacturing method according to the present invention will be described below in conjunction with the accompanying drawings and preferred embodiments. , features and their effects are described in detail below.

[0038] Figure 2A is a front view of a scoring wheel according to an embodiment of the present invention, Figure 2B is its side view. also, Figure 3A -D is a side view which shows the manufacturing process of the scribing wheel of this embodiment. When manufacturing scoring wheel 10, for example, at first in the center of disc 11 of the scoring wheel substrate made of superhard alloy or ceramics such as Figure 3B A through hole 12 serving as a shaft hole is formed as shown.

[0039] Next, the shaft of a motor or the like is connected to the through ho...

Abstract

The invention relates to a scribing wheel and a method for manufacturing the scribing wheel. The scribing wheel ensures high strength in end face of segmented substrate obtained by severing brittle material-made substrate scribed by the scribing wheel. A diamond film is formed on the periphery of the scribing wheel by grinding the periphery of the scribing wheel into V-shaped. The band-shaped part of the ridge with the V-shaped front end forms a grinding surface (15) through rough grinding in the vertex angle (Alpha 2) mode. Moreover, the band-shaped part including the ridge in the grinding surface (15) is grinded through finish machining so that a grinding surface (16) with a vertex angle (Alpha 3) is formed. The grinding width (w) for the edge through rough grinding and finish machining for the ridge is more than 20mum. Therefore, the concave-convex of the ridge and the inclined surface at the front end of a knife is reduced and the strength in end face plane of the severing brittle material-made substrate scribed is improved.

Description

technical field [0001] The invention relates to a scoring wheel for marking brittle material substrates such as ceramic substrates or glass substrates and a manufacturing method thereof. Background technique [0002] The existing known scoring wheel is made of a disc made of cemented carbide or sintered diamond, and its peripheral portion is cut obliquely from both sides, and a V-shaped blade tip is formed on the peripheral surface. The marking wheel has a through hole in the center, and is used as a marking head or the like which is rotatably pivoted to the marking device. [0003] Conventionally, in order to form a V-shaped blade tip on the peripheral surface of the scoring wheel, firstly, a through hole 102 is formed in the center of the circular plate 101 . Figure 1A A side view of the circular plate 101 is shown. Next, if Figure 1B side view shown in, Figure 1C As shown in the front view, the peripheral portion is ground into a V-shape from both sides to form a bl...
