The present embodiment also discloses the manufacturing method of above-mentioned more points of teeth high-speed cutting piece, specifically:
More points of tooth high-speed cutting pieces include two kinds of materials, first is that metal powder material, second is that diamond powder.
1. preparing metal powder: (being mass percent below) Fe content: 10%, Cu:59%, Sn:10%, Ni:6%, Zn:
2%, Co:8%, alloyed powder: 3%, (CeO2:0.3%, rich La rare earth-Ni alloy: 0.3%, mischmetal-Ni are closed rare earth metal 2%
Gold: 0.8%, Al-Ce alloyed powder: 0.6%).The gross mass percentage of metal powder material is 84%.
The mass percent of diamond is 16%, 35/40 diamond in diamond: 50%, 40/45 diamond: 50%.
The mixing time that configured powder is put into three-dimensional mixed powder machine is 5 hours.
2. cutter head cold moudling: the pressure control of the specific mold cold moudling of configured powder, cold pressing is existed
90Mpa。
3. sintering: more points of tooth high-speed cutting pieces after cold moudling are placed in 10 hours of sintering in continuous tunnel furnace, sintering
Temperature is controlled at 850 DEG C.
4. road puts the first edge on a knife or a pair of scissors processing after: the more points of tooth high-speed cutting pieces sintered are opened the diamond of bit interface by blade grinding machine
To exposure.
More points of tooth high-speed cutting pieces being made by above-mentioned technical process, can fully meet the wear-resisting of EN13236
Property standard.
In use, the present embodiment is mounted on machine by centre bore 2, shown in arrow of the direction of rotation refering to Fig. 2, by
It is less than the thickness of outer cutter head 3 in the thickness of interior saw disc 1, therefore in cutting process, interior saw disc 1 does not connect substantially with material to be cut
Touching reduces Cutting Drag, accelerates cutting heat dissipation, greatly improves cutting speed.As shown in Figure 6: Fig. 6 abscissa indicates not
Same cutting sheet, ordinate indicate cutting speed, and wherein the dry wave 1 of helical teeth and the dry wave 2 of helical teeth indicate the sample data of the present embodiment,
Four kinds of different materials are cut by comparison, it can be clearly seen that the present embodiment cutting speed with higher.
Saw blade is in cutting process, and the first skewed slot 6, the second skewed slot 4 and cutter head groove 5(are wherein on cutter head groove 5 under width
It is narrow), so that Cutting Drag is reduced to minimum, in addition takes into account the safety of saw blade.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
