Description
(1) technical field：
The present invention relates to cutting element, specifically a kind of diamond cutting tool and its making with composite structure plating
Method.
(2) background technology：
Diamond tool is mainly used in processing hard brittle material (such as：Sapphire, special cermacis, monocrystalline silicon, gem and jade etc.).Its
Middle service life is to weigh the important indicator of diamond tool, the main abrasion with diamond knife edge layer of failure of diamond tool
Come off failure, based on the inadequate fracture failure of matrix strength.According to investigation and test result indicate that, diamond tool failure mode
Often since most weak spot, when there are diamond particles and comes off in certain point in diamond knife edge layer, whole coating quickly
Will near the particle detachment point continuously come off, and ultimately result in whole tool failures.Factual survey finds, when most weak spot
When starting shedding off, often the overwhelming majority of coating also stands intact, and diamond particles are intact, sharp.If the weakness can be strengthened
Point, the service life of whole diamond tool will extend significantly, and the utilization rate of valuable diamond particles will also be greatly improved.
The material that diamond tool is processed, essentially hard brittle material, and diamond tool is generally electro-plating method preparation.
The tiny superhard particles produced in process, its hardness is far above coated metal hardness, now, when diamond particles come off
Afterwards, the superhard particles that cutting process is produced reversely grind coated metal, and coated metal is worn away totally quickly, cause Buddha's warrior attendant nearby
Stone particle hold not enough, further comes off, and spreads from a point quickly, during high-speed cutting superhard material, expands
Exhibition speed faster, can cause whole diamond tool to fail due to the failure of a point quickly, when serious, or even can may wear to base
Body, causes diamond tool matrix insufficient strength to cause fracture.Meanwhile, continuously distributed diamond tool occurs in cutting process
Diamond drop-off can influence the surface quality of cutting material, the crystalline material higher for processing request, can therefore cause waste product
Appearance, cause huge loss.
Coating comes off for flexible diamond tool (such as：Diamond fretsaw, annular diamond fretsaw, annular diamond belt
Saw etc.) it is the most notable in the influence of high-speed cutting hard brittle material, by taking annular diamond fretsaw as an example, a diameter of 0.5mm annulars gold
When diamond wire saw cuts 6 inches sapphire crystal with the linear velocity of 20m/s, after there is particle detachment in certain point in scroll saw, one
As within half an hour scroll saw wear and rupture, linear velocity faster when, rupture time is shorter.
Above mentioned problem, be due to diamond tool in manufacturing process existing defects, the defect often turn into Buddha's warrior attendant lapicide
The most weak place of tool, is also the control point of diamond tool service life.
