1. Kuoma kwakanyanya
Chinhu chikuru chakanakiramavhiri ekukuya akagadzirwa nemagetsikuoma kwazvo. Izvi zvinodaro nekuti chisungo chesimbi chakaiswa electroplated chinoshandiswa kugadzira vhiri iri chinowanzo gadzirwa ne nickel kana nickel-cobalt alloy. Chisungo ichi chine chimiro chakakora chinowedzera kubatana uye kuoma kwese. Mavhiri ekukuya akaiswa electroplated anopa kuoma kwakanyanya kupfuura bronze ne resin abrasives. Kuvakwa kwakabatana kwemavhiri ekukuya akaiswa electroplated kunopa mabhenefiti anopfuura kuoma. Kana achishandiswa pakukuya, mavhiri aya anopa kugadzikana kuri nani nekuti tsanga dzawo dzakanamirwa zvakasimba kusimbi. Izvi zvinoita kuti vhiri rekukuya riwane mhedzisiro yakafanana kunyangwe paine kushushikana kwakanyanya. Pamusoro pezvo, chinhu ichi chinobatsira kuwedzera hupenyu hwevhiri rekukuya.
2. Maburi akaderera
Chimwe chinhu chinoita kuti mavhiri ekukuya akagadzirwa nemagetsi asiyane nemamwe ari mukirasi yavo ndechekuti ane maburi mashoma kupfuura chero chishandiso chipi zvacho chinokwesha.
Kuboorwa kwevhu (Porosity) inzira yekuyera kuti pane maburi mangani aripo mukati mechinhu. Kuboorwa kwevhiri rekukuya kunogona kukanganisa zvikuru kushanda zvakanaka uye kugara kwenguva refu kwechishandiso. Semuenzaniso, mavhiri ekukuya anowanzo shandiswa anogona kuva nemaburi anosvika makumi ezana muzana, izvo zvinoderedza kushanda kwawo. Resin kana bronze-bonded abrasives anewo maburi akawandisa kupfuura zvigadzirwa zvakaputirwa.
Kune rumwe rutivi, kupinza kwemavhiri ekukuya ane electroplated kwakada kuita zero. Izvi zvinoita kuti ave maturusi akasimba uye akavimbika muindasitiri. Kupinza kwakaderera kwemavhiri ekukuya ane electroplated kunobatsirawo kana uchifunga nezvekugara kwawo kwenguva refu. Maturusi ekukuya ane simba rakawanda uye kugadzikana kwakakosha pakukuya zvinhu zvakasiyana-siyana. Mavhiri ekukuya ane electroplated haana kupinza uye anopa simba rakawanda uye kugadzikana, zvichiita kuti ave akakodzera kushandiswa kwekukuya kunoda kunyatsorongeka uye kururama. Kusiyana nemavhiri akacheneswa, ane maburi akavhurika, mavhiri akacheneswa ane electroplated akabatanidzwa nesimbi zvizere. Izvi zvinoreva kuti zvidimbu zve abrasive zvakasungirirwa zvakananga kune substrate yesimbi. Izvi zvinoita kuti kupararira kwezviyo zvinokweshana pavhiri kuve kwakaenzana, zvichiita kuti riwane mhedzisiro yakafanana nekushandiswa kwega kwega. Kupinza kwakaderera kwemavhiri akacheneswa kunobatsirawo kubvisa matambudziko ekuvharika. Kuvhara kunoitika kana vhiri riine kupinza kwakawandisa, zvichikonzera kuunganidzwa kwemarara anonzi swarf. Izvi zvinogona kukanganisa zvakanyanya mashandiro echishandiso. Mavhiri ekukuya ane electroplated akagadzirwa kudzivirira kuvharika nekupa chisungo chakasimba, chakafanana, zvichiita kuti machipisi abviswe pamusoro pekukuya.
3. Musanganiswa wakasimba kwazvo
Chimwe chinhu chakakosha chekushandisa mavhiri ekukuya edhaimani akagadzirwa nemagetsi ndiko kubatana kwakasimba pakati pesimbi nezvinhu zvinokwesha. Chisungo chesimbi chiri muchikamu chekushanda chinowanikwa zvakanyanya mugrit, zvichigadzira chisungo chakasimba uye chinogara kwenguva refu kupfuura mamwe marudzi emavhiri. Kusanganiswa uku kunovimbisa kubatana kwakakwana pakati pechinhu chinokwesha nechishandiso chebasa, zvichikonzera maitiro ekukuya anoshanda zviri nani. Kubatanidzwa kwechikamu chebasa chakabatanidzwa nesimbi kwakasimbawo, zvinoreva simba guru rekubata. Basa iri rinokosha pakukuya zvinhu zvakasiyana-siyana.
Mavhiri edhaimani akagadzirwa nemagetsi anogona kubata huwandu hwakawanda, zvichiita kuti ave akakodzera kukuya simbi dzakaoma senge tungsten carbide. Nesimba rayo rekubata, chinhu chinokwesha hachizodonhe nguva isati yakwana, zvichiita kuti chisakwanise kuumbwa nehupfu.
4. Kuwanda kwakanyanya
Pamavhiri ekukuya akagadzirwa nehupfu, huwandu hweabrasive muchikamu chekushanda hunowanzova 50% kusvika 150%, uye huwandu hweabrasive huri 10% kusvika 30%. Huwandu hweabrasive hwevhiri rekukuya redhaimani rakaiswa electroplated hunenge 200%, uye huwandu hweabrasive hunogona kusvika kupfuura 65%. Kuwanda uku kwezvinhu zvinobaya kunowedzera hupenyu hwebasa uye kunovandudza mashandiro eabrasive. Huwandu hwakawanda hwezvinhu zvinobaya mumavhiri ekukuya edhaimani akaiswa electroplated imhaka yemaitiro akasiyana ekugadzira.
Zvichienzaniswa nemavhiri ekukuya echinyakare akagadzirwa nekusanganisa tsanga dzinokwesha ne binder wodzidzvanya kuita chimiro, mavhiri ekukuya edhaimani akagadzirwa ne electroplated anogadzirwa ne electroplated layer yemadhaimani pa substrate yesimbi. Maitiro aya anoita kuti zvidimbu zvedhaimani zviparadzirwe zvakaenzana uye zvibatanidzwe zvakasimba ku substrate yesimbi, zvichigadzira kubatana kwakasimba kuti zvishande zvakanaka panguva yekukuya.
Kuwedzera kune izvi zvina zvakanakira, mavhiri ekukuya edhaimani ane ma electroplated ane zvimwe zvakanakira zvakawanda.
Chekutanga, dzakasimba zvikuru uye dzinogona kutsungirira tembiricha yakakwira uye kumanikidzwa pasina kurasikirwa nehunhu hwadzo kana chimiro chadzo. Dzinopawo nzvimbo yekukuya yakachena uye chaiyo, zvichiita kuti dzive zvishandiso zvakanaka zvekushandisa nemazvo. Chimwe chakanakira mavhiri ekukuya edhaimani akagadzirwa nemagetsi ndechekuti anogona kushandiswa muzvinhu zvakasiyana-siyana, kusanganisira zvinhu zvakaoma senge tungsten carbide neceramics. Kugona kushandiswa uku kunoita kuti dzive sarudzo yakakurumbira mumaindasitiri akati wandei anosanganisira mota, ndege, uye zvemagetsi.
