Unokukhetha njani i-carbide blade enesamente?

I-Carbide insert sisixhobo esisetyenziswa ngokubanzi kwi-high-speed machining. Olu hlobo lwezinto ziveliswa ngumgubo we-metallurgy kwaye luqukethe amasuntswana e-carbide enzima kunye ne-adhesives yensimbi ethambileyo. Okwangoku, kukho amakhulu eengxube ezahlukeneyo ze-WC-based cemented carbide, uninzi lwazo zisebenzisa i-cobalt njenge-binder, i-nickel kunye ne-chromium zikwayinto eqhelekileyo yokubopha, kunye nezinye izinto ze-alloy nazo zinokongezwa.

Ukukhethwa kwe-carbide blade ene-cemented blade: Ukuguqula i-cemented carbide blade yinkqubo ephambili ye-cemented carbide processing technology, ngokukodwa kumashishini okuvelisa oomatshini obunzima, ukukhethwa kwesixhobo kubaluleke kakhulu. Ngokwezixhobo ezahlukeneyo zokucwangcisa, xa kuthelekiswa nomatshini oqhelekileyo, ukujika okunzima kuneempawu zobunzulu obukhulu bokusika, isantya esisezantsi sokusika kunye nesantya sokutya esicothayo. Isibonelelo somatshini kwicala elinye sinokufikelela kwi-35-50 mm. Ukongeza, ngenxa yebhalansi engalunganga ye-workpiece, ukungalingani kokusasazwa kwenani lezixhobo zoomatshini kunye nokungalungelelani kwamalungu kunye nezinye izinto, ukungcangcazela kwesibonelelo somatshini kubangela ukuba inkqubo yokulinganisa eguquguqukayo itye ixesha elininzi leselula. kunye nexesha elincedisayo. Ngoko ke, ukuze kuqhutywe iinxalenye ezinzima kunye nokuphucula imveliso okanye izinga lokusetyenziswa kwezixhobo zoomatshini, kufuneka siqale ngokunyusa ubukhulu kunye nesantya sokutya komgangatho wokusika. Sifanele sinikele ingqalelo ekukhethweni kweeparitha zokusika kunye namaqabunga, siphucule isakhiwo kunye nejometri yee-blades, kwaye siqwalasele izinto eziphathekayo. Iimpawu zamandla, ngaloo ndlela ukwandisa iiparitha zokusika kunye nokunciphisa kakhulu ixesha lokusebenza.

Izinto eziqhelekileyo ezisetyenziselwa i-blade ziquka i-high-speed steel, i-carbide ene-cemented, i-ceramics, njl. Ubunzulu obukhulu bokusika bunokufikelela ngokubanzi kwi-30-50mm, kwaye isibonelelo asilingani. Kukho umaleko oqinileyo phezu kwendawo yokusebenza. Kwinqanaba le-machining elibi, ukugqoka i-blade kwenzeka ikakhulu ngendlela yokugqoka i-abrasive Isantya sokusika ngokuqhelekileyo si-15-20 m / min. Nangona ixabiso lesantya yi-agglomeration kwi-chip, ubushushu obuphezulu bokusika benza indawo yoqhagamshelwano phakathi kwetshiphu kunye nomphezulu wesixhobo sangaphambili kwimeko yolwelo, ngaloo ndlela kuncitshiswe ukungqubana kunye nokuthintela ukudityaniswa kwesizukulwana sokuqala seetshiphusi. Isixhobo se-blade siya kukwazi ukunxiba kwaye sixhathise impembelelo. I-ceramic blade inobulukhuni obuphezulu, kodwa amandla okugoba aphantsi kunye nokuqina kwempembelelo ephantsi. Ayifanelekanga ukujika okukhulu kwaye inemiphetho engalinganiyo. I-carbide ene-cemented inoluhlu lwezinto eziluncedo ezifana "nokumelana nokunxiba okuphezulu, amandla okugoba okuphezulu, ukuqina kwempembelelo elungileyo kunye nobunzima obuphezulu", ngelixa i-coefficient ye-coefficient ye-cemented carbide iphantsi, enokunciphisa amandla okusika kunye nobushushu bokusika, kwaye iphucule kakhulu ukuqina. yeblade. Ifanele ukwenziwa ngokurhabaxa kwezixhobo zobunzima obuphezulu kunye nokujika okunzima. Lukhetho olufanelekileyo lokuguqula izinto ze-blade.

Ukuphucula isantya sokuguqula i-carbide efakwe kumatshini onzima yenye yezinto eziphambili zokuphucula ukusebenza kakuhle kwemveliso kunye nokunciphisa umjikelezo wemveliso. Kule nkqubo, isixa esikhulu se-surplus sinqunyulwa sibe yimivimbo emininzi, kwaye ubunzulu be-stroke nganye buncinci kakhulu. Ukusebenza kokusika kwe-blade kunokuphucula kakhulu isantya sokusika, ngaloo ndlela kuphuculwe ukusebenza kakuhle kwemveliso, ukwandisa ubomi benkonzo, kunye nokunciphisa iindleko kunye nenzuzo.
