Description
Technical field
The present invention relates to super hard abrasive tool preparation field, particularly a kind of preparation of fine granularity Study on Brazed Superabrasive Tools
Method.
Background technology
Soldering refers to the technique for connecting two kinds of materials by the high temperature melting of solder.Its main feature is that solder fusing, and it is female
Material does not melt.Study on Brazed Superabrasive Tools refers to the super hard abrasive using diamond, cubic boron nitride as representative being welded in base steel
The tool with working ability prepared on body.Mainly include：Grinding tool, cutting tool, drilling tool three are main kind of.
Current Study on Brazed Superabrasive Tools is mostly used the types solder such as Ni-based, copper-based, silver-based and super hard abrasive is welded,
Make solder fusing by modes such as sensing heating, resistance heatings, since such as elements such as titanium, chromium of the active element in solder to surpass
Hard grind material is securely connect with steel matrix.To ensure that super hard abrasive not by element influences such as oxygen, the nitrogen in air, generally requires protection
Atmosphere, mostly using vacuum mode or inert gas.
Fine granularity Study on Brazed Superabrasive Tools can be widely applied to accurate cutting, grinding, drilling field, and main processing is with steel
Stone material and plastics that it is the non-ferrous metal, marble, ceramics that represent as representative that iron, which is the ferrous metal, copper, aluminium that represent, rubber
The emerging composite material of glue for representative etc..
Heretofore described fine granularity refers to abrasive grain of the granularity between the mesh of 80 mesh ~ 400, corresponding coarseness abrasive grain
Refer to the abrasive grain between the mesh of 30 mesh ~ 80.Conventional super hard abrasive tool is being prepared since granularity focuses mostly on before the mesh of 30 mesh ~ 80
When can be there are two types of mode, one kind spills abrasive material and solder grain for direct cloth, and one kind is cloth spills superhard abrasive again after coating cream solder
Material.In the case of greater particle size, aforesaid way can be realized preferably.And when super hard abrasive granularity is less than 80 mesh,
Average-size maximum only 0.2mm, particle size become smaller, and prepare difficulty and greatly improve, specifically as follows there are Problem Summary：
1. being difficult to realize uniformly, no matter which kind of mode to carry out cloth using and spill in a manner that cloth is spilt, granularity is smaller, than
Can easily it reunite greatly on surface.
2. fine granularity super hard abrasive large specific surface area, it is easier to which there are the phenomenon that oxidation, corrosion.
3. according to the matching of solder and granularity, the single required amount of solder of super hard abrasive is small compared to big grain size abrasive grain to be obtained
It is more, and since solder has the process of fusing and solidification, its embedding on abrasive grain is caused to influence bigger with climbing, is not easy abrasive grain
Exposure, embedding depth is too deep, and abrasive grain is difficult to play function.
In addition, for fine granularity super-hard abrasive is made preferably to be matched with solder, there is such mode：Fine granularity is superhard
Abrasive material uniformly mixes by a certain percentage with solder, and mixed material then is applied to matrix surface, if this mode is used to prepare
Individual layer abrasive material tools are not easy uniformly, that is, to be not easy to ensure that subtle granular cell layer is equably arranged in matrix surface, if occurring superhard
, then easily there is cut in finished surface in abrasive material lamination phenomenon, this is being unacceptable in Precision Machining field.Therefore, how
Abrasive grain is made well to be brazed, and super-hard abrasive individual layer is evenly distributed with, and becomes industry problems.
The Chinese invention patent of Patent No. 201110366572.8 has studied the side of fine-granularity diamond single layer soldering
Method, the method first heat solder in vacuum drying oven, shape layer solder layer, then carry out surface grinding process to solder layer again, then
Diamond abrasive grain cloth is spilt in solder alloy layer surface.Such mode has following limitation：
（1）Tool needs to heat twice, of high cost.In addition, it is necessary to increase the grinding process process on surface, for complicated table
Surface treatment increases process difficulty.
（2）The cloth of diamond abrasive grain spills the distribution for also determining diamond surface, and diamond grit is smaller, uniformity
It is more difficult to accurately be ensured.
（3）To perpendicular or cambered surface, there are the risks that solder trickles, and cause solder layer uneven when being brazed diamond.
（4）Under the conditions of fine granularity super-hard abrasive, solder layer is very thin, and existing surface tension causes pair after high temperature melting
The embedding of abrasive grain and climb that there are certain difficulties.
Can be seen that by above-mentioned analysis for tool with single layer of super hard abrasive, reasonably using solder to abrasive grain into
Row soldering, becomes the problem of industry, does not solve the problems, such as this, then super hard abrasive tool application in accurate, ultraprecise cutting, grinding,
Drilling processing is not known where to begin then.

Specific embodiment
The present invention is described in further detail with specific better embodiment below in conjunction with the accompanying drawings.
Signified fine granularity Study on Brazed Superabrasive Tools of the invention includes tool base and single layer soldering in tool base
The super hard abrasive on surface.Wherein, the superhard material that super hard abrasive is granularity between the mesh of 80 mesh ~ 400.Super hard abrasive shape is more
Kind, it is simplified model, if super hard abrasive shape is spheroidal as shown in Figure 1, and radius is R, then its volume is。
A kind of preparation method of fine granularity Study on Brazed Superabrasive Tools, includes the following steps.
Step 1, prepared by compound pellet：Using granulating process, solder is wrapped up into the periphery of superabrasive particles, is formed
Compound pellet.It is required according to preparing, determines the type of super hard abrasive granularity and corresponding solder and dosage and superhard abrasive
Intergranular away from etc. parameters.
The grain size of compound pellet is mainly determined by the granularity of super-hard abrasive and the dosage of required solder.Solder
Dosage determined by super hard abrasive granularity and abrasive grain spacing.
To realize that super-hard abrasive is well brazed, super hard abrasive is embedded using solder in advance, is prepared glomerate multiple
Close pellet, it is assumed that the radius R1 shown in FIG. 1 of compound pellet, then compound pellet have and formula be calculated as below according to volume relationship：
Wherein, K is represented under the single good brazing conditions of abrasive material, the ratio between solder dosage volume and super hard abrasive volume.
Also it is to be preferably brazed super-hard abrasive, required solder dosage volume is about the K of the super-hard abrasive of equal volume
Times, wherein K takes 0.8~1.45 more excellent.
As shown in Figure 1, superabrasive particles 1 wrap up solder particle 2 all over the body, it is to be achieved by granulating process.
During powder processed, super-hard abrasive can be bonded glomeration by solder.
In addition, above-mentioned super hard abrasive is preferably diamond, cubic boron nitride, polycrystalline diamond and polycrystalline cubic nitridation
It is one or more in boron.Above-mentioned solder is preferably Ni-based, one kind in copper-based and silver-based etc., further preferably copper
Base, acid bronze alloy hardness is low, and welding performance is excellent, even if after super-hard abrasive is embedded completely, since super-hard abrasive is relative to conjunction
Gold solder density is small, and after solder fusing, super-hard abrasive floats, and remains able to exposure.And the solder at the top of super-hard abrasive,
It can be removed by preliminary sharpening technology.Even if not removing, after preliminary use, the effect of sword is also can reach out, so as to reality
Now well it is brazed super hard abrasive.
Step 2, inert particulate ball is selected：The fusing point and boiling point of inert particulate ball are required to be more than 1100 DEG C, and the inertia
When particle sphere is below 1100 DEG C, metallurgical chemistry does not occur with super hard abrasive, solder, tool base material and react.It is lazy
Property particle sphere is preferably one or more in silica, alundum (Al2O3) or titanium oxide etc..It is required according to preparing, selection is closed
The radius of inert particulate ball is denoted as R2 by the suitable inert particulate radius of a ball.
The grain size of inert particulate ball is mainly determined that is, compound pellet spacing is equal to compound ball by the compound pellet spacing arranged
The sum of grain diameter and the diameter of inert particulate ball.
Step 3, prepared by mixture：The inert particulate ball that compound pellet and step 2 prepared by step 1 selects utilizes batch mixing
Agent is uniformly mixed, and forms mixture.
Due to inert particulate ball, there are certain density variations with compound pellet, are not easy to reach mixed uniformly effect, because
This needs to add volatilizable batch mixing agent wherein, and batch mixing agent ingredient is required to volatilize, and do not influence brazing property.
The volatilization temperature of above-mentioned batch mixing agent is preferably shorter than 100 DEG C, and batch mixing agent does not occur with super hard abrasive and solder
Chemical reaction.Further, preferably ethyl alcohol or methanol etc..
Step 4, adhesive coated：Cleaning tool matrix surface, one layer of coating is viscous in tool substrate surface after the cleaning
Agent is tied, the boiling point of the binding agent is more than the boiling point of batch mixing agent.
The volatilization temperature of above-mentioned binding agent is preferably 120-550 °, can be played compound pellet is Nian Jie with inert particulate ball solid
Fixed purpose.Further, binding agent is preferably pressure sensitive adhesive and acetone according to volume ratio 1:2~1:15 carry out preparation formation.
Step 5, cloth spills mixture：Mixture cloth prepared by step 3 is spilt to the tool base for being coated with binding agent in step 4
Body surface face.Effect after mixture cloth is spilt is as shown in Figure 2.
If directly cloth spills the compound pellet that super-hard abrasive is formed with alloy welding powder, the spacing mistake of postwelding super-hard abrasive at this time
Small, macro manifestations are overstocked for super-hard abrasive, will be unfavorable for chip removal heat dissipation, and the growth of heat is then for delicate machine tools
Fatal.
Step 6, extra mixture is removed.
Since mixed granula has certain viscosity, the particle for spreading in adhesive surface differs and is set to single berth exhibition, it is possible to
To accumulate pattern, as shown in Figure 2.At this point, apply certain temperature there will be batch mixing agent volatilization, you can allow nonadherent binding agent
Particle come off.Since pellet compound before cloth is spilt has been uniformly mixed with inert particulate ball, individual layer spreads in tool table
Compound pellet present in the particle in face and inert particulate ball are equally distributed.
It removes extra mixture namely removes the compound pellet 7 adhered in Fig. 2 and the inert particulate ball 8 of adherency.Specifically go
Except method is：The tool base that cloth in step 5 is spilt to mixture heats, and heating temperature requirement at this time is more than batch mixing agent
Boiling point and less than the boiling point of binding agent, when the batch mixing agent volatilization of tool substrate surface, preferably by contact or non-contact
Formula applies the mode of external force, removes the extra mixture not being connected with binding agent, and tool substrate surface is made to be formed such as Fig. 3 institutes
The uniformly distributed particle landforms of the individual layer mixture that shows.So as to high precision machining, there is no the phenomenon that multi-player super-hard abrasive grain stack, it is easy to
Ensure machining accuracy.
In addition, there is the encirclement of solder around single super-hard abrasive, the brazing property of every super-hard abrasive ensure that.
This is highly beneficial for obtaining good processing performance.
The mode that external force applies is more preferably soft hairbrush direct contact type, the impact of contactless Tiny pore and non-connects
Touch vibration come off etc. in one kind.
Since super-hard abrasive granularity is smaller, after batch mixing agent volatilization, specific surface area increase, super-hard abrasive is contacted with tool base
Face increases, and can form larger adhesion strength, therefore can reach the thorough individual layer of mixture and sprawl effect.Namely the abrasive grain formed
Landforms are single layer of abrasive particles structure, and high precision machining, there is no the phenomenon that multi-player super-hard abrasive grain stack, be easy to ensure machining accuracy.
Step 7, it is brazed：The tool base for having individual layer mixture uniformly distributed in step 6 is heated to pricker under protective atmosphere
Temperature is welded, which is more than binding agent boiling point but less than 1100 DEG C；Binding agent volatilizees, solder fusing and by superhard abrasive
Grain is partially embedded.
The mode of above-mentioned soldering is sensing heating under resistance heating under vacuum brazing or protective atmosphere or inert gas shielding
One kind in, further preferred vacuum resistance soldering so as to can guarantee brazing quality, reduce air-flow and the shadow of the rate of heat addition
It rings.
After above-mentioned mixture individual layer is sprawled on the tool base, when being brazed heating, since brazing temperature is more than binding agent
Volatilization temperature, therefore, the cementation of compound pellet and inert particulate ball is lost in the adhesive layer volatilization of tool substrate surface
It goes, but since the solder of compound pellet surface can melt trickling, it will it sprawls and climbs, super-hard abrasive is embedded, by
In abrasive grain, not only bottom is surrounded by solder, and top also exists, therefore solder subregion can be to super-hard abrasive surface shape
Into a laminated gold solder bed of material, but since gravity and alloy disclose the difference with super-hard abrasive density, super-hard abrasive floats
Exposure, and then solve super hard abrasive distribution when prepared by fine granularity super hard abrasive doctor and be not easy uniformly, super hard abrasive soldering shape
The uppity problem of looks.
Step 8, inert particulate ball is removed：After the completion of soldering, by way of applying external force, preferably mode of vibration will
The inert particulate ball removal of tool substrate surface, you can obtain required fine granularity soldering super-hard abrasive particle tool.
Since inert particulate ball is not reacted with solder, but the filling of its position makes solder flow to superhard abrasive
Grain reaches the soldering effect of optimization.And inert particulate ball can be carried out after postwelding is gone by vibrating, applying shape mode
Removal.Thus obtain the super-hard abrasive landforms that surface is arranged according to design requirement.Since inert particulate ball is not present, super-hard abrasive
It is not only well brazed, but also larger chip space is formed between abrasive grain, conducive to grinding heat dissipation, chip removal, this is for Precision Machining
