Abstract
The present invention is a kind of thin diamond glomerocryst cutter production technology, use fine-grained diadust as primary raw material, adding a certain amount of ceramic as binding agent, be pressed into base substrate after mix homogeneously, base substrate synthesizes dimond synneusis blade in cubic hinge press.This dimond synneusis blade crystal grain is relatively thin, and the product surface fineness such as the hard alloy of processing, aluminium alloy is good, and vitrified bond enhances its wearability, and cutter life is long.
Description
Technical field
The invention belongs to superhard material field, produce work particularly to one thin diamond glomerocryst cutter
Skill.
Background technology
Dimond synneusis cutter begins to use from 20 century 70s, replaces carbide tool adding
Hard and the crisp difficult-to-machine material aspect of work shows unmatched excellent properties.It is mainly used in optics
Glass, high alumina ceramic, various stone material and gem, the processing of semiconductor silicon kind material.
Additionally in terms of the processing of the non ferrous metal and their alloy such as copper, aluminum, dimond synneusis also has very
Good effect.
Diamond raw material hardness is the highest, needs to synthesize at high temperature under high pressure glomerocryst.Typically by thickness
The method raising blank of diamond particles grating and the compactness extent of glomerocryst, and coarse grained addition shadow
Ring the surface quality of converted products.Therefore, synthesize thin diamond glomerocryst and can be effectively improved processing product
The surface quality of product.
Summary of the invention
The invention provides a kind of thin diamond glomerocryst cutter production technology, processing can be effectively improved and produce
The surface quality of product, tool life.
It is an object of the invention to realize by the following technical solutions, according to the present invention propose a kind of thin
Diamond glomerocryst cutter production technology, it comprises the steps of employing diadust as mainly
Raw material, adds ceramic as binding agent；Base substrate it is pressed into after mix homogeneously in ball mill；Institute
State base substrate in cubic hinge press, synthesize dimond synneusis blade.
The purpose of the present invention can also use techniques below measure to realize.
Aforesaid thin diamond glomerocryst cutter production technology, described diadust, account for powder total
The 60-80% of weight, granularity is 4-6 micron.
Aforesaid thin diamond glomerocryst cutter production technology, described ceramic binding agent is
The mixing of one or more in 3Y-ZrO2, SiC, TiC, TiN and B powder, it is total that this binding agent accounts for powder
The 20-40% of weight, binding agent granularity is 0.5-2 micron.
Use above technological means, the invention have the advantages that
Use single fine-grained diadust as primary raw material, it is ensured that crudy；Add one
Quantitative ceramic, as binding agent, improves the anti-wear performance of cutter；Fine-grained vitrified bonding
As filling, form grating with diadust, it is ensured that cutter compactness extent；Suppress after mix homogeneously
Becoming base substrate, base substrate synthesizes dimond synneusis blade in cubic hinge press.
