Technical field
It is top that the utility model relates to diamond, belongs to field of mechanical technique.
Background technology
The tradition diamond is top to be structures such as carbide alloy, tool steel; Not wear-resisting, life-span is short, the precision hold facility is poor.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art structure, the utility model provides diamond top.
The technical scheme that the utility model technical solution problem is adopted is: diamond is top, and top part connects composite polycrystal-diamond, and the drift angle angle is at 45 °-135 °.
Diamond is top, and top part connects composite polycrystal-diamond (hereinafter to be referred as PCD).
PCD after diadust and metal powder (or alloyed powder) fully mix, is compounded on the hard alloy substrate through HTHP in the press cavity.
Because reasons such as the space of cavity, prior art can only be synthesized the less composite sheet of volume, be welded to composite sheet on the top matrix, be processed into finished product then.
The beneficial effect of the utility model is following: wear-resisting, life-span is long, the precision hold facility is good.
