Step 3, the cutter head of colding pressing that step 2 is obtained is carried out into microwave vacuum sintering（Stove evacuation is evacuated to 0.01Pa first, then
Argon gas to normal pressure is passed through, then proceedes to be evacuated to 0.01Pa）, under argon gas sintering atmosphere（Argon gas is passed through to stove pressure extremely
1-15KPa）, temperature be 900 DEG C under the conditions of be incubated 10min obtain diamond saw blade, wherein the step 3 obtain it is every
Individual adjacent tool tips are provided with carbon barrier.
After tested, diamond saw blade consistency is 96.67%, and hardness is 94.50HRB.
Comparative example 4
Conventional vacuum sintering specific implementation step be：
Step 1, first by the powder of following masses percentage：25%Fe powder, 10%Co powder, 45%Cu powder, 8%Ni powder, 9%Sn powder and
3%SiC powder is well mixed to obtain mixed-powder；Add diamond mixing, diamond consumption Gd=ρdV, ρd=0.88K,(ρd- knife
Contain diamond quality, the concentration of K- diamonds, V- cutter heads volume in head unit volume)；Wherein Fe powder, Co powder, Cu powder, Ni
The granularity of powder, Sn powder and SiC powder is 100~200 mesh；Diamond particles are 30~45 mesh；
Step 2, the mixed-powder for obtaining step 1 are added in punching block, compressing under 150MPa pressure to obtain cutter head of colding pressing；
Step 3, the cutter head of colding pressing that step 2 is obtained is put into mould carries out vacuum-sintering（Stove evacuation is evacuated to first
0.01Pa, then passes to argon gas to normal pressure, then proceedes to be evacuated to 0.01Pa）, under argon gas sintering atmosphere（Argon gas be passed through to
Pressure is to 1-15KPa in stove）, temperature be 900 DEG C under the conditions of be incubated 15min obtain diamond saw blade.
The diamond saw blade consistency that comparative example 4 prepares is 93.18%, and hardness is 86.42HRB.
Can be drawn by four groups of case study on implementation：Microwave vacuum sintering has obvious advantage compared to conventional vacuum sintering.
Microwave vacuum sinters optimised process：850 DEG C of sintering temperature, is incubated 4min, and obtaining diamond saw blade consistency is
97.37%, hardness is 96.20HRB.And the vacuum-sintering of routine is incubated 15min at 900 DEG C, cutter head consistency is 93.18%,
Hardness is 86.42HRB.Therefore, drawn from the consistency and hardness analysis of sintered body：Microwave sintering can significantly reduce sintering temperature
Degree, shorten sintering time and fast densified, the heat waste of diamond can be reduced, improve the service life of cutter head.
Specific embodiment of the invention is explained in detail above in association with accompanying drawing, but the present invention be not limited to it is above-mentioned
Implementation method, in the ken that those of ordinary skill in the art possess, can also be before present inventive concept not be departed from
Put that various changes can be made.
