Lub tuam txhab tsim cov ntawv uas tsis yog-planar composite nrog cov duab sib txawv thiab cov kev qhia tshwj xeeb xws li hom wedge, daim duab peb sab cone hom (pyramid type), truncated cone type, triangular Mercedes-Benz type, flat arc structure, thiab lwm yam. Cov txheej txheem tseem ceeb ntawm polycrystalline pob zeb diamond composite sheet yog saws, thiab cov qauv saum npoo yog nias thiab tsim, uas muaj ib tug sharper txiav ntug thiab kev lag luam zoo dua. Nws tau dav siv nyob rau hauv drilling thiab mining teb xws li pob zeb diamond khoom, cov menyuam lub khob hliav qab, cov khoom siv mining, thiab crushing machinery. Nyob rau tib lub sijhawm, nws yog qhov tshwj xeeb tshaj yog haum rau cov haujlwm tshwj xeeb ntawm PDC laum cov khoom, xws li cov hniav tseem ceeb / cov hniav, cov hniav loj, thiab cov hniav thib ob.
