Kuita kweCeramic Alumina Abrasive Particles inogona kuvandudzwa nekuwedzera zvishoma brittle yakanyungudutswa alumina kuti iite composite abrasive mavhiri. Panguva ino, zvinodikanwa kuti uzive kureba kwearc yekucheka kwegumbo pane workpiece, kuitira kuti uone chiyero chekukuya. Silicon carbide: SiC abrasive ine yakasikwa yakapinza chimiro. Inokodzerakugayazvinhu zvakaoma (zvakadai secemented carbide). Nekuda kwekupinza kwayo, inokodzerawo kugadzirisa zvinhu zvakapfava, sealuminium, mapolymers, rabha, simbi ine simba shoma, alloys emhangura nemapurasitiki.
Dhaimondi: Madhaimondi echisikigo uye ekugadzira anogona kushandiswa kukuya. Dhaimondi imhando yepamusoro-yakanyanya kuoma yekabhoni. Nekuti ine hukama nesimbi (simbi ialloy yesimbi uye kabhoni) uye inoita kupfeka nekukurumidza, haina kukodzeraMachiningferrous materials, asi dhaimani inonyanya kukodzera pakukuya zvinhu zvisiri zveferrous, titanium, ceramics uye cermets. CBN: Kufanana nedhaimani, CBN inodhura zvakanyanya abrasive.
Mutengo wevhiri rakasimba rinokwesha rinopfuura zvakapetwa ka50 pane wevhiri rinogadzika, asi hupenyu hwaro hwesevhisi hunopfuura zvakapetwa ka100 kupfuura hwevhiri rinogadzika. Kunyange simbi yakaoma zvikuru ivhu, inongopfekwa zvishoma. CBN inonyanya kukodzeramachinengferrous zvinhu, kunyanya kana chimiro chegumbo rekukuya chinodiwa kuti chichengetedzwe kwenguva yakareba, senge kukuya kwemujaho mukutakura. Uye zvakare, CBN inonyanya kukodzera maitiro ekudzoreredza vhiri, nekuti mabheti madiki uye kutsiva vhiri kunoda kupfekedzwa panguva yekumisikidzwa, ndicho chinhu chikuru chinotungamira mukushandiswa kwemavhiri.
Nekuti CBN ichaita nemvura pane tembiricha yakakwira uye nekukurumidza kupfeka, ethylene glycol kana mafuta inofanira kushandiswa. Chisungo chevanhuwo zvavokugayavhiri rinogona kunge riri ceramic, resin kana purasitiki, nepo chisungo cheyakanyanya kuomarara abrasive inogona kuvharwa pagumbo rekukuya nesimbi yakanyungudutswa matrix kana electroplating nickel layer. Iri rudzi rwekukuya vhiri haripindiki uye harina maburi.
Thekugayafluid yesimbi bond uye electroplated vhiri rekugaya zvinofanira kunyatsosarudzwa kudzivirira vhiri rekukuya risatsvedza. Iyo hombe ine simba ye hydraulic pressure inogadzirwa pakucheka arc panguva yekutsvedza inosimudza vhiri rekukuya, zvichitungamira mukuipa kwekupedza basa uye kukurumidza kwekupfeka kwevhiri.
