Abstract

The utility model relates to a novel diamond circular saw blade, which comprises a bit 1, a basal body 2 and diamond coating layers 3, wherein the bit is formed by sintering molding via thermal pressure after the even mixture of diamond grains and metal powder, the basal body 2 is welded together with the bit 1 and the diamond coating layers 3 are attached to both faces of the basal body. The bit 1 is in a turbine shape, both faces of the bit 1 are respectively provided with grooves 1a, the basal body 2 is provided with a center hole 2d connected with an electric tool and the diamond coating layers 3 on both of the faces of the basal body are distributed in a paracurve shape. The utility model has the advantages that the utility model solves the insufficiency and the defects that when the existing saw blades works, the saw blades can be clamped which results in deformation and break of the basal body, short service life of the saw blade, low work efficiency, etc.; the utility model provides a novel diamond circular saw blade with the advantages of sharpness, high durability, stable product performance, long service life and high work efficiency; the utility model can be used for sawing and grinding brittle and hard materials, such as cast iron, stone, etc.

Description

Novel diamond disc

Technical field

The utility model relates to a kind of novel diamond disc, particularly a kind of welded type turbo tooth coating matrix diamond disc, and the sawing that can be widely used in crisp and hard materials such as cast-iron pipe, stone material is ground.

Background technology

Saw blade uses more and more widely in the work such as present municipal road and bridge maintenance, building, finishing.Diamond disc is when crisp and hard materials such as cutting cast iron pipeline, stone material in the prior art, usually adopt general novel diamond disc, its function only is applicable to single cutting, build generally speaking, all need processing object is carried out grinding after the cutting such as finishing, do not carry out the coating diamond on the common diamond circular saw film base body, phenomenon such as binding when occurring matrix distortion, cracking, cutting at work, and can't realize grinding action.

The utility model content

The purpose of this utility model is to overcome the defective and the deficiency of prior art, provides a kind of sharp durable, not only can cut but also novel diamond disc that can grinding.

The technical solution of the utility model is: a kind of novel diamond disc comprises cutter head, matrix, coated with CVD (chemical vapor deposition) diamond layer.Cutter head is mixed after hot pressed sintering forms by metal dust and diamond particles, and matrix welds together with cutter head after machining, and cutter head is turbine shape, establishes chip area on its working face, and the degree of depth of groove is 1/3～1/2 of a cutter head thickness; Described coated with CVD (chemical vapor deposition) diamond layer is parabola shaped distribution.

The beneficial effects of the utility model are: rotating speed is slow when having solved the work of existing saw blade, matrix distortion fracture, saw life is short, deficiency and defectives such as inefficiency, provide a kind of sharp durable, properties of product are stable, and the life-span is long, the novel diamond disc of high efficiency, the sawing that can be used for crisp and hard materials such as cast iron, stone material is ground.

Description of drawings

Accompanying drawing is the organigram of novel diamond disc.

Specific embodiments

Figure of description is an enforcement optimal way of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.

As shown in the figure: novel diamond disc comprises cutter head 1, matrix 2, coated with CVD (chemical vapor deposition) diamond layer 3.Cutter head 1 is mixed by metal dust and diamond particles after Thermocompressed sintering and forming, and matrix 2 welds together with cutter head 1 after machining.Cutter head 1 is turbine shape, is provided with a plurality of groove 1a above it, welds together with matrix 2, and matrix 2 is provided with the centre bore 2d that links to each other with electric tool, and coated with CVD (chemical vapor deposition) diamond layer 3 is parabola shaped distribution on the matrix two sides.
