Ngokuthuthuka kwezimboni, imboni yokucutshungulwa kwensimbi nayo ithuthuka ngokushesha, futhi izinto ezintsha ezahlukahlukene kanye nezinqubo ezintsha ezintsha zivela njalo. Kodwa-ke, ikhwalithi yokucubungula nokusebenza kahle kokucubungula kwemikhiqizo kuqinisekisiwe futhi kuyathuthukiswa. Lapho ukhetha uketshezi olufanele lokusika insimbi, Ukuncishiswa Komhlaba kokungcoliswa kwemvelo sekube isixhumanisi esibalulekile. Kodwa-ke, ukukhetha uketshezi lokusika insimbi kumathuluzi ahlukene omshini nakho kuyinkinga enzima ukuyikhetha.

1. Izinhlobo ezijwayelekile zokusika uketshezi lwamathuluzi omshini we-CNC

Ukuze uvumelane nezikhathi zokucubungula ezahlukene kanye nezidingo zenqubo, izinhlobo zoketshezi lokusika insimbi nazo zihlukene, ezihlukaniswa kakhulu zibe izigaba ezimbili ngokuya ngamakhemikhali kanye nesimo, okungukuthi uketshezi lokusika olusekelwe emanzini kanye noketshezi lokusika olusekelwe ku-oyela.

1. Uketshezi lokusika olusekelwe emanzini lubhekisela emanzini okusika okudingeka ahlanjululwe ngamanzi kusengaphambili. Ama-emulsion alwa nokugqwala, ama-emulsions e-lubricant anti-rust, ama-emulsions okucindezela ngokweqile kanye nama-microemulsions ayingxenye yalesi sigaba. Indima yoketshezi lokusika olusekelwe emanzini ngokuvamile ngokuyinhloko ukupholisa nokuhlanza, futhi umphumela wokugcoba awubonakali.

2. Uketshezi lokusika olusekelwe ku-oyili lubhekisela oketshezini olusikiwe olungadingi ukuhlanjululwa ngamanzi uma lusetshenziswa. Amafutha amaminerali ahlanzekile, uwoyela onamafutha, izithasiselo ezinamafutha, uwoyela wamaminerali, uwoyela wokusika umfutho owedlulele ongasebenzi kanye namafutha okusika ingcindezi eyedlulele konke kungokwalolu hlobo. Ngokuphambene noketshezi lokusika olusekelwe emanzini, uketshezi lokusika olususelwa kuwoyela lunemiphumela esobala yokuthambisa, kodwa lunekhono elingenamandla lokupholisa nokuhlanza.

2, ukukhethwa kokusika uketshezi lwamathuluzi ahlukene omshini

Amathuluzi okucubungula ahlukene, ngenxa yokusebenza kwawo okuhlukile kwamathuluzi, izici ezibonakalayo ezifanele ukucubungula nazo zihlukile, ngakho-ke kufanelekile ukusebenzisa izinhlobo ezahlukene zokusika uketshezi.

1. Ngamathuluzi enziwe ngezinto zensimbi zejubane eliphezulu, ngesikhathi sokusika okuphakathi nendawo, ukushisa akukukhulu, ngakho-ke kufanelekile ukusebenzisa uketshezi lokusika olusekelwe kumafutha noma i-emulsion. Ekusikeni ngesivinini esikhulu, ukusetshenziswa kwamanzi okusika okusekelwe emanzini kungafinyelela umphumela omuhle wokupholisa ngenxa yesizukulwane esikhulu sokushisa. Ngalesi sikhathi, uma kusetshenziswa uketshezi lokusika olususelwa kuwoyela, kuzokhiqizwa inkungu enkulu kawoyela, ezongcolisa imvelo futhi ibangele kalula ukushiswa kwendawo yokusebenza, okuzothinta ikhwalithi yokucubungula kanye nempilo yesevisi yethuluzi. . Ngaphezu kwalokho, kungcono kakhulu ukusebenzisa izixazululo ezicindezela kakhulu ezinamanzi noma ama-emulsions okucindezela okwedlulele ngesikhathi somshini onzima, kanye nama-emulsions okucindezela okwedlulele noma amafutha okusika ukucindezela okwedlulele afaneleka kakhulu ukuqeda.

Insimbi enesivinini esikhulu isebenzisa imisebenzi yokusika isivinini esiphakathi, futhi isivinini sayo singama-70m/m. Insimbi enesivinini esikhulu ingxubevange yensimbi equkethe izakhi ezifana ne-tungsten ne-chromium ukuze kwandiswe ubulukhuni bayo nokumelana nokugqoka; noma kunjalo, ubulukhuni bazo kanye nekhwalithi yokumelana nokugqoka kwehliselwa ezingeni elingamukeleki ngenxa yamazinga okushisa angaphezu kuka-600°C. Nokho, amafutha okusika ancibilika emanzini angasetshenziswa ukugcina izinga lokushisa lawo lokusebenza lingaphansi kuka-600°C.

2. Ngamathuluzi e-carbide enosimende, njengoba ezwela kakhulu ekushiseni okungazelelwe, amathuluzi kufanele ashiswe futhi apholile ngokulinganayo ngangokunokwenzeka, ngaphandle kwalokho kulula ukubangela ukuphuka. Ngakho-ke, uketshezi lokusika olususelwa kuwoyela olune-conductivity yokushisa ephansi ngokuvamile lusetshenziswa, futhi inani elifanele lezithasiselo zokulwa nokugqoka liyengezwa. Uma usika ngesivinini esikhulu, fafaza ithuluzi ngokugeleza okukhulu koketshezi lokusika ukuze ugweme ukushisa okungalingani. Futhi le ndlela inganciphisa ngempumelelo izinga lokushisa futhi inciphise ukubukeka kwenkungu yamafutha.

3. Ama-alloys e-Cast (i-chromium cobalt tungsten) Lawa ma-alloys ayingxenye ye-non-ferrous esekelwe ku-cobalt. Uma izinga lokushisa layo lingaphezu kuka-600 ℃, liqinile futhi linokumelana kangcono nokugqokwa kunensimbi enesivinini esikhulu. Lokhu kungasetshenziselwa ukusika ngesivinini esikhulu, futhi kungasetshenziselwa ama-alloys okunzima ukusika kanye nemisebenzi yokusika eyenza ukushisa okuphezulu. Ama-cast alloy azwela kakhulu ekushintsheni okukhulu kwezinga lokushisa, njengokuphazamiseka okungazelelwe ekusebenzeni kokusika. Zifaneleka kakhulu ekusebenzeni okuqhubekayo kokusika futhi zingasebenzisa amafutha okusika amanzi ancibilikayo.

4. Njengoba amathuluzi e-ceramic namathuluzi edayimane anokumelana okuvelele kakhulu kokushisa okuphezulu kunokugqoka i-carbide enosimende, ngokuvamile basebenzisa amasu okucubungula okomile. Ngezinye izikhathi, ukuze ugweme ukushisa okuphezulu ngokweqile, uketshezi lokusika olusekelwe emanzini olune-conductivity ephakeme ye-thermal luphinde lusetshenziswe ngokuqhubekayo futhi ngokugcwele ukuthululela indawo yokusika.

5. Ama-Carbides asetshenziswa kakhulu embonini yokucubungula insimbi. Ngokuvamile zibizwa ngokuthi ama-carbides ayi-cemented noma ama-alloys aqinile kakhulu. Zenziwa ngokungeza i-carbide powder ye-tungsten, i-titanium, i-niobium, ne-tantalum kusikhunta se-cobalt kanye ne-sintering ekushiseni okuphezulu. Ukushintsha isilinganiso kanye nohlobo lwama-carbides ensimbi kungakhiqiza izinhlobo ezahlukene zama-carbides anosimende. I-carbide enosimende isetshenziswa ngoba isabugcina ubulukhuni nokumelana nokugqoka ezingeni lokushisa eliphezulu elingu-1000°C. Ngokuvamile zisetshenziswa njengezinto ezifakwayo noma amakhanda okusika ashintshwayo. Ikhanda ngalinye linomumo ohlukile kanye ne-engeli. Ingafakwa kabusha futhi igcinwe ngokwezidingo ezahlukene. Enye indlela yokukhiqiza elula ukumboza ungqimba lwe-carbide ekhanda lethuluzi lokusika. Indlela yayo yokukhiqiza ukumboza ithuluzi le-carbide lendabuko ngokuhwamuka kwe-titanium carbide. Ikhanda lokusika elenziwe ngale ndlela linokumelana okuphezulu kwe-abrasion, futhi i-cutter ngokwayo akulula ukuyiphula. Amathuluzi e-Carbide avame ukusetshenziswa kanye namafutha okusika ancibilika emanzini, kodwa kufanele akhethwe ngokucophelela. Izithasiselo ezithile zizokonakalisa insimbi emboze i-cobalt.

6. Ingxenye eyinhloko yamathuluzi okusika i-ceramic / idayimane ye-ceramic i-alumina, engagcina ubulukhuni bayo nokugqoka ukumelana nokushisa okuphezulu. Kodwa-ke, njengoba kushiwo ngenhla, ukuqina kwezinto ezibonakalayo, kuba buthakathaka kakhulu, okwenza amathuluzi e-ceramic angafaneleki ukusika okungapheli noma ukuthuthumela kwemithwalo kanye noshintsho lokushisa. Uma umshini, ungasebenzisa amafutha okusika angancibiliki emanzini (amafutha okusika asekelwe ngamafutha) noma ungasebenzisi amafutha okusika nhlobo, gwema ukusebenzisa amafutha okusika amanzi ancibilikayo.

7. Ithuluzi elinzima kakhulu lokusika idayimane, kodwa futhi lintekenteke. Amadayimane angasetshenziswa emisebenzini yokucubungula i-aluminium ephezulu, le alloy iqukethe izinhlayiya ze-silicon eqinile, izogqoka ngokushesha amathuluzi e-carbide. Ibuye ilungele ukugaya nokucubungula izinto ezingezona ezoni, njengamatshe nosimende. Idayimane ingenziwa nge-oxidized ekushiseni okuphezulu, ngakho-ke ayifanele ama-alloys okunzima ukuwacubungula. Ngenxa yokuthi iqinile kakhulu, ivame ukusetshenziselwa ukugaya. Amafutha okusika asuselwa kuwoyela noma amafutha okusika ancibilika emanzini noma uketshezi lokusika lokwenziwa lungasetshenziswa.
