Mavharuvhuanoshandiswa seseti yakakwana yemidziyo yekuparadzanisa mhepo mumakemikari masisitimu, uye mazhinji ekuisa chisimbiso kwawo anogadzirwa nesimbi isina tsvina.Muchigadziro chekugaya, nekuda kwekusarudzwa kusina kunaka kwezvinhu zvekukuya uye nzira dzisina kururama dzekukuya, kwete chete kushanda kwekugadzira kwevhavha kunoderedzwa, asiwo hutano hwechigadzirwa hunobatwa zvakanyanya.Zvinoenderana nehunhu hwemidziyo yesimbi isina tsvina, takasarudza kusimba kwekushanda kwakasimba uye kusagadzika kwekupfeka, uye kunaka kwechigadzirwa kuchiri kukanganiswa mushure mekunge zvidimbu zveabrasive zvaputswa mukugadzirisa.Mumakore achangopfuura, takadzidza zvinhu zvinoputika izvo zvakagadziriswa zvekugadzirisa zvinhu zvinogona kuchengetedza kupinza, zvakadai se white corundum uye chromium oxide, kusarudzwa kwezvishandiso zveabrasive uye nzira yeabrasive, nezvimwewo. uye W5, nezvimwewo zvina zvakakodzera.Kuburikidza nekuedza, yakasimudzirwa uye inoshandiswa mukugadzirwa chaiko, izvo zvisingangogadziri kunaka kwenzvimbo yekuisa chisimbiso, asi zvakare inovandudza mashandiro ekugadzira uye inowana mhedzisiro yakanaka.
Kuti vheji igeze workpiece, kutanga, chigadziro chekukuya chinosungirirwa nejecha, uye ipapo kuputika kunowanikwa kuburikidza nehutu hunoumbwa nemusanganiswa wezviyo zvinoputika uye mvura inokuya.Kukuya (grinding force) zvinoreva simba rinoshanda pachikamu chekukuya.Ndiro simba rinoshandiswa kune chigayo chekukuya uye kuita pamusoro pepamusoro kuti chigadziriswe kuburikidza neabrasive particles.Kana kudzvinyirirwa kuri kudiki, kugaya kuchaita kudiki, uye kumanikidza kunowedzera.Iyo yekukuya inowedzerwa, uye kugona kwekugaya kunovandudzwa.Zvisinei, kana dzvinyiriro ichiwedzera kune imwe kukosha, saturation inoitika, uye kushanda zvakanaka kwekugaya kunowanzosvika pakukosha kukuru.Mushure meizvozvo, kana kudzvanywa kwenzvimbo yeyuniti kuchiramba kuchiwedzerwa, kushanda kunoderera panzvimbo.
Izvi zvinodaro nekuti mavharuvhu abrasive particles ane imwe muganhu wekumanikidza kuramba.Kana kukosha uku kwapfuura, ivo vanopwanywa, zvichiita kuti mabrasive particles aite zvakanaka uye achidzikisa kugona kuzvigaya.Naizvozvo, iyo unit yekumanikidza inofanirwa kutariswa zvinoenderana nesimba uye kupwanya maitiro eiyo abrasive.Mushure mebvunzo, anotevera ma paramita anofanirwa kuwanzo kusarudzwa: ① Mukugaya kwakashata, kune chena corundum abrasive, sarudza 0.2 kusvika 0.5 MPa.③ Panguva yekukuya zvakanaka, sarudza 0.03～0.12MPa yewhite jade abrasive.
Kukuya (grinding speed) zvinoreva kukurumidza kufamba kwechishandiso chiri pamusoro pechishandiso.Kukuya kumhanya chinhu chakakosha dhizaini dhizaini kudzora huwandu hwekubviswa kwasara, kukurumidza kwekubvisa uye kunaka kwenzvimbo yakagadziriswa.Mufananidzo 2 ndeye yakajairika hukama curve pakati pekubvisa saizi yebasa, kushata kwemuchina uye kumhanya kwekugaya.
Basa rekugadzira chigadziro uye chigadziro chayo chekugadzirisa zvinhu ndechekugadzirisa kwekanguva uye kuwana imwe nzira yekukuya, uye kuendesa chimiro chayo chejometri kune workpiece mune imwe nzira.Nokudaro, zvinhu zveguyo zvinofanira kuva nekuiswa kwakakodzera kwezviyo zvinoputika uye kuchengetwa kwenguva refu kweiyo geometric yakarurama.Grey cast iron HT200 chinhu chakanakira kugadzira kugaya.Chimiro chayo chine cementite yakaoma uye isingapfekeki, ferrite ine kusimba kwakanaka uye plastiki, uye inewo graphite, ine mafuta ekuzora uye iri nyore kugadzira uye kugadzirisa..
Kana nguva yekukuya inodiwa kuti uwane iyo yakataurwa pamusoro pemhando yakakura kupfuura nguva inodiwa kubvisa margin.Iko kumhanya kwekugaya kunofanira kuderedzwa zvakakodzera.Mushure mekuyedza, zvinotevera kumhanya kwakakosha zvakanyanya: ①Panguva yekugaya, kumhanya kwekukuya maturusi kana maworkpiece kuti avhurwe i20-50m/min.②Apo vharafu iri mukukuya, kukurumidza kwechigadziro chekugadzira kana workpiece kuti ivhurwe i 6 ~ 12m / min.Kusarudzwa kwepamusoro roughness value Kushata kwepamusoro ndechimwe chezviratidzo zvikuru zvemhando yepamusoro.Iine simba guru pamusoro pebasa repamusoro.Iyo ine mhedzisiro yakananga pamusoro peabrasion yepasi, kuomarara kwekubata uye kuisa chisimbiso kuita, uye panguva imwechete inokanganisa kushanda uye hupenyu hwechigadzirwa.Paunenge uchishandisa nzira dzakasiyana dzekukuya uye saizi yezvikamu, kushata kwepamusoro kunowanikwa kwakasiyanawo.
