Single-crystal diamond tool plane selection

Diamond crystals are cubic plane, since each crystal form and surface atomic arrangement atom density difference and the distance between the different planes,

resulting in a natural diamond crystal anisotropy, so the performance of the diamond crystal surface only of the physical and mechanical different performance

, Ease of manufacture and service life which are not the same, the microstructure of the crystal surface damage strength are also significant differences. Microscopic

diamond crystals Hertz strength test method used to determine, since the diamond is a typical brittle material, the strength values ​​are generally larger deviation, the

main

Depends on the shape and distribution of the stress distribution range, so suitable for use probability theory to analyze. When the effect of stress is the same, (110)

crystal plane maximum probability of damage, (111), followed by (100) crystal plane of the minimum probability of breakage. Ie external force, (110)

The most easily damaged planes, (111) crystal face, followed by (100) the most difficult to break. Although the (110) crystal plane grinding is higher than the (100)

crystal plane, but the experimental results show that the (100) crystal face and the other plane has a higher resistance to stress, corrosion, and thermal degradation

capability. Integrated micro combined strength

Considered together with the (100) plane to do before and after the cutting tools flank, easy sharpening tool edge high-quality, easy to produce micro-chipping.
Normally be carried out according to requirements of the tool planes of the single crystal diamond tool selection. In general, if the request to obtain the highest

strength diamond tool, should be used (100) surface as the tool before the flank; if required resistance to mechanical wear diamond tool, then select

With the (110) crystal face as the tool before the flank; if required chemical wear resistant diamond cutting tool,Diamond blade it is desirable use of (110) crystal plane as the

tool rake face, (100) crystal face as the flank, or the front , are used flank (100) crystal plane. These requirements need the help of crystal

Body orientation technology to achieve.
