Okokuqala, izinyathelo ezijwayelekile zokusika uketshezi lokukhetha
Ukukhethwa koketshezi lokusika kufanele kunqunywe ngokucabangela izici ezibanzi ezifana namathuluzi omshini, amathuluzi okusika, nobuchwepheshe bokucubungula, njengoba kuboniswe ezinyathelweni zokukhetha uketshezi lokusika.
Ngaphambi kokukhetha uketshezi lokusika ngokwendlela yokucubungula kanye nokunemba okudingekayo, izinto ezivimbelayo njengokuphepha kanye nokwelashwa koketshezi olulahlwayo kuyasethwa. Ngalezi zinto, kunganqunywa ukuthi kukhethwe yini izigaba ezimbili ze-oyela-based cutting fluid noma uketshezi lokusika olusekelwe emanzini.
Uma ukuvikelwa komlilo nokuphepha kugcizelelwa, uketshezi lokusika olusekelwe emanzini kufanele lucatshangelwe. Lapho ukhetha uketshezi lokusika olusekelwe emanzini, ukukhishwa koketshezi olulahlwayo kufanele kucatshangelwe, futhi ibhizinisi kufanele libe nezindawo zokwelapha uketshezi olulahlwayo. Ezinye izinqubo, ezinjengokugaya, ngokuvamile zisebenzisa uketshezi lokusika olusekelwe emanzini kuphela; ngokusika ngamathuluzi e-carbide, uketshezi lokusika olususelwa kuwoyela lubhekwa ngokujwayelekile.
Amanye amathuluzi omshini adinga ukusetshenziswa koketshezi lokusika olususelwa kuwoyela ngesikhathi esiphezulu, ngakho-ke ungashintshi kalula kuketshezi lokusika olusekelwe emanzini, ukuze ungaphazamisi ukusebenza kwethuluzi lomshini. Ngemva kokulinganisa lezi zimo, unganquma ukuthi ukhetha uketshezi lokusika olusekelwe kumafutha noma uketshezi lokusika olusekelwe emanzini. Ngemuva kokunquma into esemqoka yokusika uketshezi, isinyathelo sesibili singakhethwa ngokuya ngendlela yokucubungula, ukunemba kokucubungula okudingekayo, ubulukhuni obungaphezulu nezinye izinto kanye nezici zoketshezi lokusika, bese ukhomba ukuthi uketshezi olukhethiwe nokusika lungahlangabezana yini izidingo ezilindelekile . Uma kunenkinga ekuhlonzeni, kuzobuyiselwa emuva ukuze kutholwe imbangela yenkinga futhi kuthuthukiswe, futhi ekugcineni kwenziwe isiphetho esicacile sokukhetha.
2. Izikhathi ezisebenzayo zoketshezi lokusika olususelwa kuwoyela kanye namanzi
Njengamanje, kunezinhlobo eziningi zoketshezi lokusika, futhi ukusebenza kwazo kuhle noma kubi. Uma zingakhethiwe kahle, zizodala imiphumela emibi. Ngokuvamile, uketshezi lokusika olusekelwe emanzini kufanele lukhethwe ngaphansi kwemibuzo elandelayo:
① Indawo lapho uketshezi lokusika olususelwa kuwoyela lungabangela ingozi yomlilo;
②Ukusika kwesivinini esikhulu kanye nokudla okuphezulu, indawo yokusika idlula izinga lokushisa eliphezulu, umusi ushubile, futhi kunengozi yomlilo.
③Ngokucabangela ukugeleza kwezinqubo zangaphambili nangemuva, kuyadingeka ukusebenzisa uketshezi lokusika olusekelwe emanzini.
④ Kufiswa ukunciphisa ukungcoliswa kanye nokungcola okuzungeze ithuluzi lomshini okubangelwa ukuchaphaza kukawoyela, inkungu kawoyela kanye nendawo yokusabalalisa, ukuze kugcinwe indawo yokusebenza ihlanzekile.
⑤ Uma kucatshangelwa intengo, kwezinye izinto ezilula ukuya emshinini kanye nezinqubo zokusika ezinezidingo eziphansi kwikhwalithi engaphezulu yezingxenye zokusebenza, ukusetshenziswa kwamanzi okusika okusekelwe emanzini okuvamile kungahlangabezana nezidingo zokusetshenziswa futhi kunganciphisa kakhulu izindleko zokusika uketshezi.
Okwesithathu, izimo ezilandelayo kufanele zicabange ukukhetha uketshezi lokusika olususelwa kuwoyela:
①Uma ukuqina kwethuluzi kunengxenye enkulu emnothweni wokusika (njengokuthi ithuluzi libiza kakhulu, kuba nzima ukulola ithuluzi, futhi isikhathi esiyisizayo sokulayisha nokulayisha side, njll.).
②Ukunemba kwethuluzi lomshini kuphezulu, futhi akuvunyelwe neze ukuxubana namanzi (ukuze kungabangeli ukugqwala).
③Izikhathi lapho isistimu yokuthambisa kanye nesistimu yokupholisa yethuluzi lomshini kulula ukuhlangana khona kanye nezikhathi lapho okokusebenza nezimo zokuhlanza uketshezi olungcolile zingatholakali
Amathuluzi e-Xinfa CNC anezici zekhwalithi enhle nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:

4. Izinyathelo zokuphepha zokusika uketshezi
⑴Uketshezi olusikayo akufanele lube nephunga elicasulayo futhi kungabikho izithasiselo eziyingozi emzimbeni womuntu ukuze kuqinisekiswe ukuphepha kwabasebenzisi.
(2) Uketshezi lokusika kufanele luhlangabezane nezidingo zokulawulwa kwemishini yokuthambisa kanye nokuvikela, okungukuthi, uketshezi olusikayo akufanele lugcwelise izingxenye zensimbi zethuluzi lomshini, kulimaze izimpawu nopende wethuluzi lomshini, futhi ungashiyi amadiphozithi aqinile e-gelatinous. kumareyili womhlahlandlela wamathuluzi womshini, ukuze kuqinisekiswe ukuphepha kwemishini nokusebenza ngendlela evamile.
(3) Uketshezi lokusika kufanele luqinisekise umphumela kawoyela wokulwa nokugqwala phakathi kwezinqubo ze-workpiece futhi ungagqwali i-workpiece. Lapho ucubungula ama-alloys ethusi, uketshezi lokusika olunesulfure akufanele lusetshenziswe. Lapho ucubungula ama-alloys e-aluminium, uketshezi olusikiwe olunevelu ye-PH engathathi hlangothi kufanele kukhethwe.
⑷ Uketshezi lokusika kufanele lube nokusebenza okuhle kakhulu kokugcoba kanye nokusebenza kokuhlanza. Khetha uketshezi olusikiwe olunomthwalo ophezulu we-PB ongahlanganisi umthamo omkhulu kanye nokuqina okuphansi kwendawo, futhi ukuhlolwa kokusika kunomphumela omuhle.
(5) Uketshezi lokusika kufanele lube nempilo ende yesevisi, futhi isikhungo somshini sibaluleke ngokukhethekile ngalesi sikhathi.
⑹ uketshezi lokusika kufanele luvumelane nezinhlobonhlobo zezindlela zokucubungula kanye nezinhlobonhlobo zezinto zokusebenza.
⑺ Uketshezi olusikiwe kufanele lube nokungcoliswa okuncane, futhi kube nendlela yokwelapha uketshezi olulahlwayo.
⑻ Uketshezi lokusika kufanele luthengeke futhi kube lula ukululungiselela. Ukufingqa, lapho abasebenzisi bekhetha uketshezi lokusika, bangaqale bakhethe uketshezi lokusika olu-2 kuye ku-3 olusebenza kahle ngokwezimo ezithile zokucubungula. Uketshezi lokusika oluthengekayo.
