Ukuhlaziywa Kwezinzuzo Eziyinhloko zeCarbide Gun Drills

Emkhakheni womshini wokugaya imbobo ejulile, ukubhoboza izibhamu ze-carbide, ngokusebenza kwazo okuyingqayizivele, kancane kancane kungena esikhundleni sokuprakthiza kwesibhamu sensimbi esinesivinini esikhulu esivamile futhi sekuphenduke amathuluzi abalulekile ezimbonini ezifana nokukhiqiza imishini, izingxenye zezimoto, kanye ne-aerospace. Izinzuzo zabo eziyinhloko zigxile kubukhulu obuningi obuhlanganisa ukusebenza kahle kwemishini, ububanzi bohlelo lokusebenza, nokulawula ukunemba.

Okokuqala, ukusebenza kahle kwemishini kuphezulu kakhulu kunaleyo yamathuluzi endabuko. I-carbide impahla ngokwayo inobunzima obuphezulu nokumelana nokugqoka okuqinile. Ihlanganiswe nedizayini ye-engeli yokusika enengqondo, ingamelana nesivinini sokusika nokuphakelayo. Uma kuqhathaniswa nokubhobolwa kwesibhamu kwensimbi okunesivinini esikhulu, ijubane lokusika lama-carbide gun drill linganyuka ngo-30% -50%. Ikakhulukazi lapho kwenziwa izimbobo ezijulile ezinesilinganiso sokujula kuya kububanzi obukhulu kuno-10:1, asikho isidingo sokuhlehla njalo ukuze kukhishwe ama-chips, okufinyeza kakhulu isikhathi somshini wembobo eyodwa futhi kuthuthukisa kakhulu ukusebenza kahle kokukhiqizwa ngobuningi.

Okwesibili, uhla lwezinto ezisebenzayo lubanzi kakhulu. Izibhamu ze-Carbide zingakwazi umshini ngokuzinza yonke into kusukela ku-carbon steel evamile ne-alloy steel kuya kuma-alloys e-titanium anamandla amakhulu nama-alloys amakhulu. Lokhu kungenxa yobulukhuni obuphezulu obubomvu bezinto zayo, ezingakwazi ukugcina ukuqina okuhle nokugqoka ukumelana ezindaweni zokusika ezishisa kakhulu, ukuxazulula izinkinga zokugqoka okulula kanye nekhwalithi embi yomshini wamathuluzi wendabuko lapho kucutshungulwa izinto ezinzima zomshini.

Ngaphezu kwalokho, ukunemba komshini kanye nekhwalithi ephezulu kungcono. Imishini yokubhoboza izibhamu ze-Carbide isebenzisa idizayini edidiyelwe yepayipi lokubhoboza ne-drill bit, enokuqina okuqinile futhi okungelula ukuphambuka phakathi nokubhola. Ukubekezelela kwe-diameter yembobo kungalawulwa ezingeni le-IT7-IT8, futhi iphutha lokuqondisa lincane kakhulu. Ngesikhathi esifanayo, umklamo obukhali onqenqemeni kanye nesakhiwo sokususwa kwe-chip esinengqondo singanciphisa ngempumelelo imihuzuko odongeni lwembobo olubangelwa ama-chips, futhi ukuqina kwendawo ngemuva komshini kungafinyelela ku-Ra1.6-Ra3.2, ukunciphisa izinqubo zokuqeda ezilandelayo.

Ngaphezu kwalokho, izindleko eziphelele zokusebenzisa ziphansi. Nakuba izindleko zokuthenga zokuqala zokubhoboza izibhamu ze-carbide ziphezulu kunezokubhobolwa kwezibhamu zensimbi ezinesivinini esikhulu, impilo yabo yesevisi iphindwe izikhathi ezingu-5-10 kunezokubhoboza izibhamu zensimbi ezinesivinini esikhulu. Ngaphezu kwalokho, banciphisa izikhathi zokushintsha amathuluzi nesikhathi sokuphumula, behlisa izindleko zokushintshwa kwamathuluzi nokulungisa amaphutha. Ngokuhamba kwesikhathi, angakwazi ukonga amabhizinisi izindleko eziningi zokukhiqiza, okuwenza afanelekele ikakhulukazi izimo zokukhiqiza ezinkulu neziqhubekayo.

Ngalezi zinzuzo ezibalulekile, ukubhoboza izibhamu ze-carbide sekuphenduke ithuluzi elikhethwayo lesimanjemanje le-deep hole machining, okugqugquzela ukuthuthukiswa okuphumelelayo kanye nekhwalithi ephezulu yemboni yokukhiqiza enembile.
