Description
Technical field
The present invention relates to machining and mechanical manufacturing field, particularly relate to a kind of preparation method of super-hard material high-wear-resistanceprecision precision support frame/block.
Background technology
Bracing frame/block is widely used in machining and machine industry, and major function is played a supporting role.The maximum difficult point of bracing frame/block is wearability and perpendicularity, usually adopts harder material such as hardened steel etc. to make bracing frame/block.Start recent years to adopt Hardmetal materials to make bracing frame/block, adopt the problem of this material to be that carbide alloy price is high, own wt weight.However, for the equipment of processing rigid alloy material, bracing frame/block that Hardmetal materials is made can not meet instructions for use.
In recent years, be that the bracing frame/BOB(beginning of block) of feature makes with superhard material.When this kind of bracing frame/block makes, normally by superhard material (such as natural diamond, polycrystalline diamond or cubic boron nitride) be welded on supporter and form bracing frame/block, the advantage of this bracing frame/block is the wearability that can increase bracing frame/block, but, due to superhard material is being welded in the process of supporter, easy appearance distortion, thus, high-precision bracing frame/block can not be produced, also there is the problem of processing technology complexity simultaneously.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art, a kind of preparation method of super-hard material high-wear-resistanceprecision precision support frame/block is provided, it is the change by the selection to superhard material, grinding process and superhard material and support substrate fixed form, make the bracing frame/block made have the feature of high-wearing feature, high accuracy and high strength, and there is the advantage that technique simply, easily realizes and cost of manufacture is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of preparation method of super-hard material high-wear-resistanceprecision precision support frame/block, comprising:
Choose the diamond compact with the first gauge, and adopt laser cutting mode that diamond compact is cut into certain geomery;
Adopt plane sharpening way to carry out grinding process to the diamond compact cutting into certain geomery, make diamond compact be thinned to the thickness of the second gauge;
The process of chamfering sharpening is carried out to the diamond compact being processed into the second gauge, chamfering sharpening processing procedure comprise to thin diamond laminated or polygonly carry out the process of chamfering sharpening, form the negative chamfered edge of 0.3*45 °;
Diamond compact after the process of chamfering sharpening is fixed in support substrate with glue adhering fixed mode, time bonding, that high viscosity anaerobic type sqtructural adhesive is evenly coated in the one side of the cemented carbide substrate of diamond compact and the stationary plane of support substrate, then the one side of the cemented carbide substrate of diamond compact is attached on the stationary plane of support substrate, apply the instantaneous pressure of more than 200 grams simultaneously, and after the natural drying of 24 hours, the diamond compact after the process of chamfering sharpening is fixed in support substrate.
First gauge of described diamond compact is 1.6 millimeters.
Second gauge of described diamond compact is 1.2 millimeters.
Described chamfering sharpening processing procedure also comprises carries out inclined-plane 45 ° of chamfering sharpenings process to a side of diamond compact, make thin layer of diamond and cemented carbide substrate coplanar in one side inclined-plane at 45 °.
