Background technology
In order to cut or drilling brittle workpiece for example stone, fragment of brick, concrete and pitch, must provide its hardness to be higher than the abrasive material of workpiece hardness.
Artificial diamond's stone granulate, natural diamond particle, boron nitride and carbide alloy are known as abrasive material in the art, and especially in these materials artificial diamond's stone granulate most widely used general in the cutting tool field.
Diamond (being called as " diamond " below) is invented out at twentieth century the fifties, and is known as the material that a kind of its hardness is higher than any other material on earth.Because this characteristic is so be used for cutting tool, grinding knife tool etc. with diamond.
Specifically, diamond is to be widely used in cutting or the various stones of grinding for example in the building field of the stone manufacture field of marble, granite etc. and cutting or grinding xoncrete structure.
Now will be to comprising cutting tip (being also referred to as " blade " below) and comprising that the cutting tool of this cutting tip describes as the diamond particles of abrasive material.
Usually, the blade type diamond cutter comprises a plurality of blades and the steel core portion that keeps this blade, and each blade has distribution diamond particles thereon.
Fig. 1 demonstrates an example of blade type diamond cutter.
With reference to Fig. 1, this blade type diamond cutter comprises a plurality of blades 11 and 12, and these blades are fixed in the discoid steel core portion 2 and have diamond particles 5 in each blade that is randomly dispersed in blade 11 and 12.
These blades produce according to powder metallurgy process, wherein diamond particles are mixed with the metal dust that is used as matrix, then with their compactings and sintering.
As mentioned above, when diamond particles was mixed with metal dust, diamond particles was not evenly distributed among the metal dust, thereby caused the stock-removing efficiency of diamond particles to reduce and the reduction in service life.
That is to say that when mixing with diamond particles with as the metal dust of matrix, size between these particles and difference of specific gravity make and cause the uneven distribution of diamond particles among metal dust thus by the diamond particles segregation.Therefore, as shown in Figure 1, in each blade, can form the cutting surface 4 that is distributed with the cutting surface 3 of too much diamond particles or is distributed with very few diamond particles on it on it.
When diamond particles was emanated as mentioned above, not only the stock-removing efficiency of cutting tool reduced, and also reduces the service life of this cutting tool.
The technology of the problems referred to above that cause as the segregation that solves by diamond particles has proposed the pattern formation technology that makes diamond particles become predetermined pattern to distribute, and demonstrated an one example in Fig. 2.
Fig. 2 demonstrates another example of blade type diamond cutter 20, and wherein diamond particles distributes according to predetermined pattern.
With reference to Fig. 2, each blade in the blade 21 and 22 has according to predetermined pattern distribution diamond particles 5 thereon.That is to say that diamond particles 5 is evenly distributed in each blade in blade 21 and 22.
According to this pattern formation technology; replacement mixes metal dust and diamond particles, is used for diamond particles being arranged in the process on the metal dust matrix according to predetermined non-random pattern and being used for the process that the metal dust matrix is arranged on the diamond particles is made metal dust and diamond particles layered arrangement by repeating.Then this laminar product is compacted into predetermined compression member, carries out sintering afterwards, form this blade thus.
Can solve by the caused problem of the segregation of diamond particles though be used for the pattern formation technology of diamond particles, can not solve because the built in problem that uses the powdered-metal matrix to cause.
That is to say that when making blade, if use metal dust to be used for matrix, then metal dust is subjected to higher pressure during the process of compacted metal matrix.In the process of this metallic matrix of compacting,, reduced productivity ratio thus because compaction tool by metallic particles heavy wear, changes or base fracture so matrix thickness often occurs.In addition, under serious situation, the size of matrix changes, and makes these blades be of different sizes respectively, thereby causes the performance difference of diamond cutter and performance to reduce.
In addition, promptly allow to adopt identical component to produce the metal dust that is used for matrix by the whole bag of tricks, for example plate, circle, rod etc. are compared obviously high but the manufacturing cost of metal dust is with metal derby.
In addition, when making blade by powder metallurgy process, must be used in proper order mix diamond particles and metal dust process, be used for the process that the mixture compacted with diamond particles and metal dust becomes to be scheduled to the process of compression member and to be used for this compression member of sintering, thereby make production process complicated.
