Uketshezi olusikayo uketshezi lwezimboni olusetshenziselwa ukupholisa nokugcobisa amathuluzi nezinto zokusebenza ngesikhathi sokusika nokugaya insimbi.
Uhlobo lokusika uketshezi
Uketshezi lokusika olusekelwe emanzini lungahlukaniswa lube yi-emulsion, i-semi synthetic cutting fluid kanye noketshezi lokusika oluphelele. I-diluent ye-emulsion i-milky white ngokubukeka; I-diluent ye-semi synthetic solution ngokuvamile iyashintsha, kanti eminye imikhiqizo imhlophe qhwa; I-diluent yesixazululo sokwenziwa ngokuvamile ibonakala ngokuphelele, njengamanzi noma inombala omncane.
Umsebenzi wokusika uketshezi
1. Ukuthambisa
Umthelela wokugcoba uketshezi lokusika insimbi ngesikhathi sokusika unganciphisa ukungqubuzana phakathi kobuso be-rake nama-chips, naphakathi kobuso bangemuva nendawo emshinini, kwakheka ifilimu yokugcoba ingxenye, ngaleyo ndlela kuncishiswe amandla okusika, ukungqubuzana nokusetshenziswa kwamandla, kunciphise izinga lokushisa elingaphezulu kanye nokugqoka kwamathuluzi kwengxenye yokungqubuzana phakathi kwethuluzi nesiqeshana sokusebenza singenalutho, futhi sithuthukise ukusebenza kokusika kwe-workpiece.
2. Ukupholisa
Umphumela wokupholisa wokusika uketshezi ukukhipha ukushisa okusika kude nethuluzi kanye ne-workpiece ngokusebenzisa i-convection kanye ne-vaporization phakathi kwayo nethuluzi, i-chip kanye ne-workpiece eshisiwe ngokusika, ukuze kuncishiswe ngempumelelo izinga lokushisa lokusika, ukunciphisa ukuguqulwa okushisayo kwe-workpiece kanye nethuluzi, ukugcina ubulukhuni bethuluzi, nokuthuthukisa ukunemba kwemishini nokuqina kwethuluzi.
3. Ukuhlanza
Enkambweni yokusika insimbi, ukusika uketshezi kuyadingeka ukuze kube nomphumela omuhle wokuhlanza. Susa ama-chips akhiqiziwe, ama-abrasive chips, i-iron powder, ukungcola kwamafutha kanye nezinhlayiya zesihlabathi, vimbela ukungcoliswa kwamathuluzi omshini, izinto zokusebenza namathuluzi, futhi ugcine unqenqema lokusika lwamathuluzi noma amasondo okugaya lubukhali ngaphandle kokuthinta umphumela wokusika.
4. Ukuvimbela ukugqwala
Enqubweni yokusika insimbi, i-workpiece izogqwala ngokuthintana nemithombo yezindaba ebolayo efana ne-sludge yamafutha ekhiqizwa ukubola noma ukuguqulwa kwe-oxidative yemidiya yemvelo nokusika izingxenye zoketshezi, kanye nobuso bezingxenye zethuluzi lomshini ezithintana noketshezi lokusika nazo zizogqwala.
Idatha enwetshiwe
Umehluko phakathi koketshezi oluhlukene lokusika
Uketshezi lokusika isisekelo sikawoyela lusebenza kahle ngokugcobisa kanye nomthelela ongemuhle wokupholisa. Uma kuqhathaniswa noketshezi lokusika olususelwa kuwoyela, uketshezi lokusika olususelwe emanzini lunokusebenza okungekuhle kokugcotshwa kanye nomthelela ongcono wokupholisa. Ukusika kancane kudinga ukuthambisa okuqinile koketshezi lokusika. Ngokuvamile, amafutha okusika asetshenziswa lapho ijubane lokusika lingaphansi kuka-30m/min.
Uwoyela wokusika oqukethe isithasiselo sokucindezela okwedlulele uyasebenza ekusikeni noma iyiphi into lapho ijubane lokusika lingeqi ku-60m/min. Ngesikhathi sokusika ngesivinini esikhulu, ngenxa yesizukulwane esikhulu sokushisa kanye nomphumela omubi wokudlulisa ukushisa okwenziwa ngamafutha okusika uketshezi, izinga lokushisa endaweni yokusika lizoba phezulu kakhulu, okuzoholela ekushiseni, umlilo kanye nezinye izenzakalo emafutheni okusika. Ngaphezu kwalokho, ngenxa yokuthi izinga lokushisa le-workpiece liphezulu kakhulu, ukuguqulwa okushisayo kuzokwenzeka, okuzothinta ukunemba kwemishini ye-workpiece, ngakho-ke uketshezi lokusika olusekelwe emanzini lusetshenziswa kakhulu.
I-Emulsion ihlanganisa i-lubricity kanye nokugqwala ukumelana kwamafutha nempahla enhle kakhulu yokupholisa yamanzi, futhi ine-lubricity enhle nempahla yokupholisa, ngakho-ke iphumelela kakhulu ekusikeni kwensimbi ngesivinini esikhulu nokucindezela okuphansi okukhiqizwa ukushisa okukhulu. Uma kuqhathaniswa noketshezi lokusika olusekelwe kumafutha, izinzuzo ze-emulsion zitholakala ekushiseni okukhulu, ukuhlanzeka, kanye nomnotho ngenxa yokuhlanjululwa ngamanzi.
