Problems solved by technology

[0004] However, when breaking ceramic substrates such as alumina, which is harder than glass substrates, the scoring wheel made of cemented carbide and the polycrystalline For the scoring wheel made of diamond sintered body, the front edge of the blade will be chipped or worn immediately, and no cracks will be formed within tens of meters
Therefore, it is practically impossible to use a scribe wheel made of cemented carbide or a sintered polycrystalline diamond to separate ceramic substrates, which are harder than glass substrates.

Embodiment Construction

[0059] Hereinafter, embodiments of the present invention will be described using the drawings. However, the embodiment shown below is merely an example for actualizing the technical idea of ​​the present invention, and there is no intention to limit the present invention to this embodiment. The present invention is of course applicable to other embodiments included in the claims.

[0060] figure 1It is a schematic diagram of a scribing apparatus 10 according to an embodiment of the present invention. The scribing device 10 includes a mobile station 11 . The moving table 11 is screwed with the ball screw 13, and the ball screw 13 is rotated by the drive of the motor 14, thereby moving in the y-axis direction along the pair of guide rails 12a and 12b.

[0061] A motor 15 is provided on the upper surface of the mobile stand 11 . The motor 15 rotates the upper table 16 in the xy plane and positions it at a predetermined angle. A tempered glass substrate 17 as a scr ibe object...

Abstract

The invention provides a scribing wheel having longer service life than heretofore in decoupling of a ceramic board or the like harder than a glass substrate using the scribing wheel having a blade comprising diamond only, and also to provide a holder unit, a scribing device, a production method for the scribing wheel and a scribing method. A blade (42) comprises diamond only, and R chamfering of0.8-5 [mu]m is carried out to a blade tip (43). By using the scribing wheel (40), crack of the blade tip can be reduced to a large extent comparing with the scribing wheel in which the R chamfering isnot carried out.

Description

[0001] This application is a divisional application of an invention patent application with the application number 201410418893.1 entitled "Scoring wheel and its manufacturing method and scoring method, holder unit, and scoring device". The filing date of the original application is August 2014 22nd. technical field [0002] The present invention relates to a scribe wheel suitable for forming a scribe line on the surface of a brittle material substrate, such as a ceramic substrate, a sapphire substrate, and a silicon substrate, which is harder than a general amorphous glass substrate, and a holder unit provided with the scribe wheel , A marking device, a marking wheel manufacturing method, and a marking method. Background technique [0003] The use of scoring wheel is closely related and inseparable to people. When breaking amorphous glass substrates such as liquid crystal panels, generally speaking, use a scoring wheel made of superhard alloy as disclosed in the patent doc...
