Embodiment Construction

[0081] A cutter wheel for cutting brittle materials and its processing method according to the present invention will be described in detail below with reference to FIGS. 1 to 5 .

[0082] A disc-shaped cutter wheel capable of cutting brittle materials, especially glass materials with a thickness of 0.1 mm to 2 mm, according to the present invention is mainly obtained by processing a special microstructure at the V-shaped cutting edge of a commonly used cutter wheel. A cutter wheel with a new structure.

[0083] The material of the cutter wheel is polycrystalline or polycrystalline diamond, or it can be diamond, cemented carbide, or a composite of these materials; the thickness of the cutter wheel is 0.3mm-5mm, and its typical thickness is 0.7mm; The diameter range of the wheel is 1mm-25mm, of which the typical diameter is 2.5mm; the diameter range of the central shaft hole is 0.2mm-20mm, of which the typical diameter is 0.8mm; the included angle ψ of the V-shaped cutting edge...

Abstract

The invention discloses a cutter wheel for cutting a brittle material and a processing method thereof. The cutter wheel is provided with a V-shaped cutting blade part (1), a disc surface (2) and an axle hole (3), wherein the periphery of the chine line l at the external edge of the V-shaped cutting blade part (1) is provided with cutting blades (4) and recess structures (5), which are alternately-distributed; each cutting blade (4) comprises curved surfaces (Part a1 and Part a2), four side surfaces (a3, a4, a5 and a6) and V-shaped cutting edges (V-shaped cutting edge 1, V-shaped cutting edge 2 and V-shaped cutting edge 3)of which the included angles are respectively psi1, psi2 and psi3; and the disc surface (2) and the axle hole are provided with grid-line grooves (6), and the cutting blades (4), the recess structures (5) and the grid-line grooves (6) are obtained by the processing in a laser scanning mode. The cutter wheel with the new structure can avoid or reduce the condition that the cutter wheel is blocked when the cutter wheel with other structures cuts the material, and can prevent the material from producing radial cracks, thereby prolonging the service life of the cutter wheel and simultaneously obtaining the high-grade cutting sections. Besides, the inner walls of the grid-line grooves (6) are coated with solid lubricant, thereby well solving the lubrication problem.

Description

technical field [0001] The invention relates to a cutting and breaking cutter wheel for brittle materials including glass, ceramics, silicon chips and semiconductors and a processing method thereof, in particular to a cutting wheel for glass cutting and a processing method thereof. technical background [0002] With the rapid development of science and technology, many fields require brittle materials to be thinner and harder, and the cutting quality requirements for brittle materials are also getting higher and higher, especially in the glass industry. The following will take glass materials as an example to illustrate. [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 glass. The material of the cutter wheel is mai...
