triangle welding cvd diamond
The microstructure of the CVD diamond is polycrystalline and has no
cutting surface. Because CVD diamond has good wear resistance, good
processing precision and high polishing degree, it is widely used
in welding tools.
CVD diamond cutters are suitable for processing materials such as
high silicon aluminum alloy, graphite, ceramics, non-ferrous

Application of CVD synthetic diamond
CVD diamond cutting tools are widely used in non-ferrous ,ceramics
,abrasive composites ,high silicon-filled aluminum,graphite and
other diffcult maching materials mechanical process
Advantages of triangle welding cvd diamond:
1. Strip structure: CVD diamond strip is uniformly worn throughout
the trimming process, the trimming section is always constant, and
the phenomenon of falling particles does not occur like the single
crystal diamond particles, so that the consistency of the trimming
section parameters can be ensured. Maximize the use of materials,
which is unmatched by granular diamonds;
2. Optimized selection: Depending on the grinding wheel and the
finishing process, CVD corrugated strips with different
cross-section dimensions can be selected and used in multiple
alignments to meet the needs of finishing. For example,
fine-grained grinding wheels should choose CVD just smaller
cross-sectional area. Stone strips, large-size grinding wheels
should choose multiple rows, etc.;
3. Manufacturing simplification: CVD diamond strips are
macroscopically isotropic, and it is not necessary to orient the
material like single crystal diamond during processing and use,
which greatly simplifies the manufacturing process;
4. CVD diamond does not contain any binder, and its thermal
stability is comparable to that of high-grade single crystal
diamond, which is far superior to PCD material.
