Upfu hwe corundum chena hunowedzera sei hupenyu hwebasa rezvishandiso?
Chii chinonyanya kurwadza kana chakaomakucheka nekukuyaindasitiri? Hakusi kuwedzera kwemari yemagetsi kana kuoma kwebasa, asi zvishandiso zvinokurumidza kupera! Kukuya mavhiri, mabhandi ekukwesha, matombo emafuta, madhisiki ekukuya… vanhu ava vanorarama vacha "parara" mumazuva mashoma, uye kuatsiva nemamwe matsva kwakafanana nekucheka nyama. Kunyanya pakugadzira zvinhu zvakaoma zvemapfupa - simbi isina ngura, alloys dzinopisa zvakanyanya, uye simbi yakaoma, zvishandiso zvinopera nekukurumidza zvekuti unoshaya chokwadi nezvehupenyu hwako.
Hei, shamwari dzekare, nhasi ngatitaurei nezvekuti chinhu ichi chidiki chisingaonekwe,upfu hwecorundum chena, rave mushonga we "kuwedzera hupenyu" hwezvishandiso? Handisi kuwedzeredza. Kana ukashandisa zvakanaka, hazvishamisi kuwedzera hupenyu hwezvishandiso kaviri, uye mari inochengetwa yese inongova mari chaiyo!
"Hazvina kunaka here? Ndichazvigadzirisa!"–Chinosimudzira "kuzvirodza" chemashiripiti
Fungidzira: rukoko rwezvimedu zvinogumbura pamusoro pevhiri rekukuyayakagomara, uye kushanda kwayo kunoderera. Panguva ino, kana chimiro chevhiri rekukuya chikagoverwa zvakaenzana nehupfu hwecorundum chena, zvinoita se "chikwata chekuchengetedza" chakavanda.
Kana chibatiso chacho chapfekwa zvakanaka pasi pesimba rekukuya uye kupisa kwekukweshana, zvidimbu izvi zveupfu hudiki zvine mukana we "kuratidza misoro yazvo" uye kutsiva zvidimbu zvikuru zvisina kusimba kuti zvigadzirezve mupendero wakapinza!
Izvi zvinoderedza kumhanya kwevhiri rese rekukuya richiva "rakatsetseka pasi", zvichibvumira vhiri rekukuya kuti rirambe rakapinza kwenguva yakati rebei, simba rekucheka hariori, uye kushanda zvakanaka kwekugadzira kwakasimba. Mabasa edu ekukuya anogadzira shafts dzakasimba, tichishandisa mavhiri ekukuya eceramic akasanganiswa neW10 micro-powder. Zvichienzaniswa nemavhiri ekukuya akajairwa, zvinotora basa rinoda kusvika 30% kuti rikuyiwe risati rada kuchekwa. Mukuru webasa anofara zvikuru.
Chinhu chikuru chekushandisa micro-powder kuti urarame chiri mu "kuenzanisa" uye "kushandisa"
Upfu hudiki chinhu chakanaka, asi hausi mushonga wekurapa, uye hausi chinhu chinogona kungoshandiswa nekungosasa zvisina tsarukano. Kana uchida kuti huwedzere hupenyu, unofanira kuteerera zvinotevera:
Sarudza "mubatsiri" akakodzera (kufananidza saizi yezvikamu): Saizi yezvikamuupfu hudiki (Nhamba yeW) inofanira kuenderana nehukuru hwezvimedu zvechinhu chikuru chinokwesha (zvimedu zvakakora)! Kana chakanyanya kuomarara, kuzadza nekurodza kuchava kwakashata; kana chakanyanya kunaka, chinogona kuputirwa chose nechinhu chinosunga uye "chinodzipwa" uye hachishande. Mutemo wechigunwe: Zvakanakira kuti hukuru hwezvimedu zveupfu hwe micro huve 1/5 kusvika 1/3 yehukuru hwezvimedu zvechinhu chikuru chinokwesha. Semuenzaniso, kana ukashandisa 46# zvimedu zvakakora, zvinonyanya kukodzera kufananidza upfu hwe micro W20-W14.
Dzidza "muyero" (chiyero chekuwedzera): Ingani hupfu hudiki hwekuwedzera? Hazvisi pachena kuti mhedzisiro yacho yakawanda sei, uye yakawanda inogona kusabatsira, zvichikanganisa simba remuchina wekubinda kana kuita kuti vhiri rekukuya riome zvakanyanya. Chiyero ichi chinoenderana nekuyedza uye ruzivo, uye chinowanzo gadziriswa mukati me10%-30% yehuremu hwese hwekukweva. Mavhiri ekukuya eResin anogona kuwedzerwa ku20%-30%, uye mavhiri ekukuya eceramic anowanzo 10%-20% zvakakwana. Usaremerwe nekuda kwezvinhu zvakasimba!
Sarudza "nzvimbo yehondo" (zvishandiso zvinoshanda):
Zvinhu zvinosanganisa mabhurawuza (mavhiri ekukuya, matombo emafuta, misoro yekukuya): Iyi ndiyo nzvimbo huru yekurwira hupenyu hweupfu hwe micropowder! Yakakodzera zvikuru mavhiri ekukuya ane resin bonds uye vitrified bonds. Fomura uye maitiro ekusanganisa ndizvo zvakakosha kuti uve nechokwadi chekuti upfu hwe micropowder hwakapararira zvakaenzana.
Zvinobaya zvakaputirwa (mabhandi ejecha, sandpaper): Pakugadzira mabhandi ejecha nesandpaper, kuwedzera hupfu hushoma (hwakaita se5%-15% yehupfu hwese) kune guruu repasi uye guruu rakaiswa pamusoro peguruu kunogona kuvandudza zvakanyanya simba rekubata zvidimbu zvinobaya, kudzivirira zvidimbu zvinobaya kuti zvisadonha nguva isati yakwana, uye zvakare kubatsira mukudzivirira kuvhara. Inoshanda zvikuru pakugadzira mabhandi ekukuya nemazvo.
Kukuya nekupukuta mvura/namatidza: Shandisa zvakanangaupfu hwe corundum chenakugadzira mushonga wekukuya kana wekuchenesa kuti upedzise zvakanyanya. Zvidimbu zvakapfava zvakanyanya uye hupfu hwakanyanya kuenderana zvinogona kuita kuti nzvimbo dzacho dzive dzakafanana uye dzisingakuvadzi zvakanyanya, uye chishandiso (polishing pad/wheel) chinopera zvishoma nezvishoma.
