Steel gritrudzi rwechigadzirwa chinogona kushandiswa seabrasiveuye counterweight.Kana yapfekwa, inosiyana zvichienderana nechimiro chayo uye kukura kwayo.Ndeipi shanduko huru? Unogona kuona izvi kubva mundima inotevera.

Saizi, chimiro uye kutaridzika kwejecha resimbivane pesvedzero huru pane abrasive wear.Vanokanganisa mutoro uye kushushikana kubva kune elastic kubata kune epurasitiki kubata uye kukonzera yakakosha kutsemuka indentation saizi uye groove saizi shanduko.

Sezvaunogona kuona, kana mutoro uye kuoma kunoramba kuripo, nzvimbo yekubatana inogarawo nguva dzose, zvichienderana nehukuru uye chimiro cheabrasive.Apo iyo Angle yepamusoro yepiramidhi, iyo yepamusoro Angle yekoni uye radius ye. sphere inodzikira, kukosha kweD/A kunowedzera. The.4/4 value of a sphere inowanzova diki pane yekoni kana koni, saka mapfekero echimedu chinopinza cheabrasive chakakwira kupfuura cheabrasive abrasive particle, kunyanya sezvo kudzika kwekoni, f, kwakakura uye kunoda kudarika t.(critical indentation deep), zvichikonzera kuitika nekupararira kwepakatsemuka.

Zvinoita sezvakaoma zvikuru kuverenga chiyero chekupfeka quantitatively maererano nehukuru uye chimiro cheabrasive pasi pemamiriro chaiwo ekushanda, kunyange zvazvo iri kuongororwa panguva ino.Nekuda kwekuti ukuru hweabrasive mune chero mamiriro ezvinhu anogara ari mukati mehumwe huwandu, ukuru, chimiro uye kutaridzika hazvina yunifomu, uye mukupfeka kwemaitiro abrasive uye piritsi rinoputika, uye abrasive yekuonana nzvimbo inowanzova 10 ~ 3O% chete yenzvimbo yese yekushanda.Kupfeka kwekupfeka hakungoenderana nehukuru, chimiro uye kutaridzika kweiyo abrasive, asiwo zvinoenderana nekuita uye friction coefficient yechiso chechinhu.Vamwe vatsvakurudzi vakaronga muenzaniso wekuratidza huwandu hwekupfeka maererano nemasimba.Iyo abrasive wear coefficient yezvinyorwa zvinogona kuratidzwa mumutsara unotevera.

Feng erda ndiyo nyanzvimugadziri of metal abrasive.Kuitira kuzadzisa zvinodiwa nevatengi, tinopa mhando dzakasiyana dzesimbi grit,high carbon angular simbi grit uyekutakura simbi yesimbi.
