Diamond achikuya mavhirianogadzirwa nedhaimondi abrasives seyakagadzirwa uye simbi hupfu, resin poda, ceramics uye electroplated simbi seanosunga maajenti.
Chimiro chediamond kugaya vhiriinonyanya kukamurwa kuita zvikamu zvitatu: kushanda layer, matrix uye transition layer.
Panyaya yekushandisa,mavhiri edhaimani achikuyaanowanzo shandiswa kugadzira simbi dzine simbi yakaderera izvo zvinonetsa kugadzirisa neyakajairwa abrasive maturusi.Semuenzaniso, inoshandiswa muminda yakadai seyakanyanya kuoma, super-yakaoma alloys (titanium, aluminium), ceramic zvinhu, nezvimwe.
Nechimiro,mavhiri edhaimani achikuyaakasiyana nemavhiri akajairika ekukuya.Mavhiri ekugaya akajairika anogadzirwa nekubatanidza abrasives akajairwa mune imwe chimiro.Iwo anowanzo sanganisira zvinhu zvitatu: abrasive, bond uye pores.Zvikamu zvikuru zve adiamond kugaya vhirindiyo diamond abrasive layer, transition layer uye matrix.
Iyo abrasive layer ibasa rekushanda, iro rinonziwo diamond layer, iyo inobata chikamu chegumbo rekukuya;
Iyo transition layer inodaidzwa kuti non-diamond layer uye inonyanya kuumbwa nemabinders, metal powders uye fillers.Shanduko yeshanduko inobatanidza zvakasimba dhaimondi kune matrix;
Iyo matrix inoshandiswa kugadzirisa iyo abrasive layer.Izvo zvinhu zvematrix zvine hukama nechinhu chebhainda.
Metal bonding agents anowanzo shandisa simbi uye alloy simbi hupfu sehwaro, uye resin bonding agents vanoshandisa aluminium alloy uye bakelite sehwaro.
