Therefore, the design of the cutting wheel cutter structure of J Tian will affect the whole process. The secret knife is attached to the outermost circumferential ridge of the surrounding area to apply a suitable surface rubbing force to perform a circular glazing on the brittle sheet: force: (.: station = announcement _ domain "glass The door follows the β ^ 第 () ~ (c) diagram 'The disc knives 1 are provided with _: ridge spacing provided with a sharp convex portion 14 盥 groove 16 structure, to carry out the brittle sheet Bu, in the Wei before the technical shot, the inner bottom of the groove 16 s ^ slightly flat structure, so The grooved knives are vertically oriented, so that the design will make the slashing and shattering dust not secret, and the dust that has not been discharged in time remains in the groove: the dust will cause the cutting The longitudinal crack is not linear; the whole i '(T1Pra=r=the yield of the fruit 2^ and the tip of the toothed tip half UipradIUS) is about the sharpness of the sharpness. The present invention proposes a cutting cutter wheel structure to effectively overcome the above problems in view of the above-mentioned shortcomings of the prior art.

Claims (1)

1316927 X. Patent application garden: 1. - A cutting wheel cutter structure' is made of polycrystalline diamond (PCD) material formed by diamond powder burning with sub-micron (submi_) self-distributed with fine surface roughness. The cutting wheel cutter structure comprises: a circumferential ridge, the two sides of which are correspondingly formed with a front oblique annular surface and a rear oblique annular surface; the plurality of cutting teeth 'the tooth top _ radius is less than; The flutes 'the 77* and the flutes are alternately arranged (10) on the ridge, wherein t both sides of the flute are centered on the circumferential ridge and extend obliquely to the anterior oblique soil The face/the rear bevel® torus' has a slope between the chip-like bottom and the cutting blade. 2. The cutting wheel cutter structure according to the invention of claim 1, wherein the cutting wheel cutter has an outer diameter of about 1 mm to 25 mm. 3. The cutting wheel cutter structure of claim 1, wherein the thickness of the butterfly cutter is between 0.5 mm and 5 mm. The invention relates to a butterfly cutter structure according to the invention of claim 3, wherein the butterfly cutter is provided with a shaft hole for the cutter mandrel to be threaded. 5.
