Cobalt, iron, tin, bronze, nickel alloy are main metallic bond material, because abrasive material and metallic bond are difficult to form chemical knot
Close, abrasive material is also simply embedded in metallic bond by machinery, and metallic bond holds low intensity to abrasive material, and instrument goes out sword ability
Difference.Therefore, both instruments abrasive material in heavy load operation can come off too early, and abrasive material utilization rate is low, and life tools are short, processing effect
Rate is low.
In order to solve the above problems, closely during the last ten years, domestic and foreign scholars research and utilization method for brazing makes super hard abrasive instrument.
Study on Brazed Superabrasive Tools, its principle is by the chemical smelting between abrasive material, solder and matrix three using high-temp soldering method
Firm holding to abrasive material is realized in gold reaction, makes it have that high in machining efficiency, chip space is big, abrasive material utilization rate is high, workpiece table
Face is difficult the significant advantages such as burn.Because of single layer soldering super hard abrasive tool making easily, at present, material processing field is with individual layer pricker
Based on weldering super hard abrasive instrument, but single layer soldering super hard abrasive instrument exposes problems with use：Due to soldering
Diamond saw blade, emery wheel, the working region of a beading are respectively the outside cylinder of the outer circumference surface, emery wheel and beading matrix of saw bit matrix
Face, the diamond abrasive on these faces is almost participated in and cuts grinding simultaneously, almost simultaneously after blunt, because being combined by force with bonding agent
Degree is high difficult for drop-off, and with the increase of processing object contact area, cutting resistance is big, and diamond abrasive is difficult to crush and goes out sword again, cuts
Efficiency and crudy reduction are cut, if reducing the diamonds of tool surfaces, though cutting force is small, cutting efficiency is high, instrument
Short life.
The content of the invention
The purpose of this utility model is to provide the good super hard abrasive of a kind of high in machining efficiency, long service life, crudy
Instrument.

Tooth height is raised after diametrically periodically first reducing step by step, and the super hard abrasive is fixed on a point tooth by brazing metal bonding agent
On the working region of section and the super hard abrasive that is fixed on narrow tooth periphery is in staged ordered arrangement.
Preferably, the super hard abrasive instrument includes matrix, super hard abrasive and brazing metal bonding agent, and described matrix external diameter is big
Small range is 60~200mm, and matrix width scope is 0.6~100mm, and described point of tooth section number is 4~16, the chip area
It is shaped as key slot or U-type groove or fish hook groove.
It is highly preferred that the super hard abrasive instrument includes matrix, super hard abrasive and brazing metal bonding agent, the narrow number of teeth model
It is 50~260 to enclose, and narrow tooth width scope is 1.5~2.5mm, and the difference of the radial height of adjacent narrow tooth is Δ h, and Δ h's is big
Small range is 0.6d~d (d is the diameter of super hard abrasive).
It is highly preferred that the super hard abrasive instrument includes matrix, super hard abrasive and brazing metal bonding agent, the narrow tooth is in footpath
It is 3 or 5 or 7 or 9 to the number in a cycle of height change.
Preferably, the super hard abrasive instrument includes matrix, super hard abrasive and brazing metal bonding agent, and the super hard abrasive is
Diamond or CBN, the brazing metal combination agent material are Ni based alloys or Cu-Sn-Ti alloys or Ag-Cu-Ti alloys.
Preferably, the super hard abrasive instrument includes matrix, super hard abrasive and brazing metal bonding agent, described point of tooth Duan Shanggong
The radial height a scopes for making region are 4~15mm.
Compared to the prior art, the present invention has the advantage that：
(1), when sawing is ground, the super hard abrasive on the maximum narrow tooth of radial height is most for super hard abrasive instrument of the invention
First start working, the super hard abrasive that this grade of super hard abrasive is run out of on the narrow tooth of the low one-level of rear radial height is devoted oneself to work, so
Super hard abrasive is set to play ablation step by step, therefore, the super hard abrasive tool life is long.
(2) super hard abrasive instrument of the invention reduces the contact area of abrasive material and processing object, by the superhard abrasive of blunt
Material is easily broken and goes out sword again, and it is small to cut grinding resistance, therefore, tool processes efficiency high, good stability, crudy are good.
