Izidingo zamathuluzi omshini we-CNC ezintweni zamathuluzi
Ukuqina okuphezulu nokumelana nokugqoka
Ukuqina kwengxenye yokusika yethuluzi kufanele kube kuphakeme kunobulukhuni bempahla yokusebenza. Ukuphakama kokuqina kwempahla yamathuluzi, kungcono ukumelana nokugqoka kwayo. Ukuqina kwempahla yamathuluzi ekamelweni lokushisa kuyoba ngaphezu kwe-HRC62. Ubulukhuni bungaba phezulu kunobujwayelekileIzingxenye zemishini ye-CNC.
Amandla anele nokuqina
Ithuluzi lithwala ingcindezi enhle kakhulu ohlelweni lokusika ngokweqile. Kwesinye isikhathi, isebenza ngaphansi kwezimo zokudlidliza. Ukuvimbela ithuluzi ukuthi lingaphuki futhi liphuke, impahla yamathuluzi kumele ibe namandla nokuqina okwanele. Ngokuvamile, amandla okugoba asetshenziselwa ukumela amandla ento yethuluzi, futhi inani lomthelela lisetshenziselwa ukuchaza ukuqina kwento yamathuluzi.
ukumelana nokushisa okuphezulu
Ukumelana nokushisa kubhekisela ekusebenzeni kwezinto zamathuluzi ukugcina ubulukhuni, ukumelana nokugqoka, amandla, nokuqina ngaphansi kwamazinga okushisa aphezulu. Kuyinkomba ehamba phambili yokulinganisa ukusebenza kokusika kwezinto zamathuluzi. Lokhu kusebenza kwaziwa nangokuthi ubulukhuni obubomvu bezinto zamathuluzi.
I-conductivity enhle ye-thermal
Uma kukhulu ukuqhutshwa kwe-thermal kwempahla yamathuluzi, ukushisa okungaphezulu kudluliselwa kusuka kuthuluzi, okulungele ukunciphisa izinga lokushisa lokusika ithuluzi nokuthuthukisa ukuqina kwalo.
Ukucutshungulwa okuhle
Ukuze kube lula ukucutshungulwa kwamathuluzi nokukhiqiza, izinto ezisetshenziswayo kufanele zibe nezakhiwo ezinhle zokucubungula, njengokufoja, ukugingqika, ukushisela, ukusika nokugaya, izindawo zokwelashwa kokushisa, kanye nezakhiwo zepulasitiki ezishintshashintshayo ezisezingeni eliphezulu zempahla yamathuluzi. I-carbide enosimende kanye nezinto zamathuluzi e-ceramic nazo zidinga izakhiwo ezinhle ze-sintering kanye ne-press-forming.
Uhlobo lwempahla yamathuluzi
insimbi enesivinini esikhulu
Insimbi enesivinini esiphezulu iyinsimbi yensimbi eyingxubevange eyakhiwe ngo-W, Cr, Mo, nezinye izakhi ze-alloy. Inokuqina kokushisa okuphezulu, amandla, ukuqina, kanye nezinga elithile lokuqina nokumelana nokugqoka, ngakho-ke ifaneleka ukucubungula izinto ezingezona ze-ferrnonferrous nezinsimbi ezihlukahlukene. Ngaphezu kwalokho, ngenxa yobuchwepheshe bayo bokucubungula umsindo, ilungele ukukhiqiza amathuluzi okwakha ayinkimbinkimbi, ikakhulukazi i-powder metallurgy high-speed steel, enezakhiwo zemishini ye-anisotropic futhi inciphisa ukucisha ukuguqulwa; ilungele ukukhiqiza ukunemba kanye namathuluzi okwakha ayinkimbinkimbi.
Ingxubevange eqinile
I-carbide enosimende inokuqina okuphezulu nokumelana nokugqoka. Lapho ukusikaIzingxenye zokuguqula ze-CNC, ukusebenza kwayo kungcono kunensimbi enesivinini esikhulu. Ukuqina kwayo izikhathi eziningana kuya kwezingamashumi amabili kunensimbi enesivinini esikhulu, kodwa ukuqina kwayo komthelela akulungile. Ngenxa yokusebenza kwayo okuhle kakhulu kokusika, isetshenziswa kabanzi njengethuluzi lempahla.
Ukuhlukaniswa nokumakwa kwama-carbides anosimende wamathuluzi okusika
I-blade eboshwe
I-1) Izinto zokugqoka zendlela ye-CVD yi-TiC, okwandisa ukuqina kwamathuluzi e-carbide enosimende izikhathi ezingu-1-3. Ukuqina kwe-coating: I-cutting Edge ayicacile futhi isiza ukuthuthukisa impilo yejubane.
2) Izinto zokumboza zendlela ye-PVD yokubeka umhwamuko obonakalayo yi-TiN, i-TiAlN, ne-Ti (C, N), ethuthukisa ukuqina kwamathuluzi e-carbide enosimende izikhathi ezingu-2-10. I-coating encane; Unqenqema olucijile; Kuyasiza ekunciphiseni amandla okusika.
★ Ubukhulu obukhulu be-coating ≤ 16um
I-CBN ne-PCD
I-Cubic boron nitride (CBN) Ukuqina kanye nokusebenza okushisayo kwe-cubic boron nitride (CBN) ingaphansi kwedayimane, futhi inokuqina okushisayo namakhemikhali. Ngakho-ke, ilungele ukukhanda insimbi eqinile, insimbi eqinile, i-superalloy, ne-carbide enosimende.
Idayimane le-Polycrystalline (PCD) Uma i-PCD isetshenziswa njengethuluzi lokusika, ifakwa ku-sinter ye-carbide substrate. Ingakwazi ukuqeda ukumelana nokuguga, ukuqina okuphezulu, okungeyona insimbi, kanye ne-nonferrononferrousaterials njenge-carbide enosimende, izitsha zobumba, ne-silicon aluminium alloy ephezulu.
★ ISO machine clamp blade classification material ★
Izingxenye zensimbi: P05 P25 P40
Insimbi engagqwali: M05 M25 M40

ukusika isivinini
Ifomula yokubala yesivinini sokusika Vc:
Kufomula:
D - ububanzi obujikelezayo bocezu lokusebenza noma ithiphu yamathuluzi, iyunithi: mm
N - isivinini sokujikeleza se-workpiece noma ithuluzi, iyunithi: r/min
Isivinini Sokucupha Ngentambo Ejwayelekile
Ijubane lokuphotha n lokujika intambo. Lapho usika intambo, ijubane lokuphotha le-lathe lithintwa izici eziningi, njengosayizi we-pitch pitch (noma umthofu) we-workpiece, izici zokuphakamisa nokwehlisa ze-motor motor, kanye nesivinini sokufakelwa kwentambo. Ngakho-ke, umehluko othize ukhona ejubaneni lokuphotha lentambo yokujika yamasistimu ahlukene e-CNC. Okulandelayo ifomula yokubala isivinini sokuphotha lapho uvula izintambo kumalebula ajwayelekile e-CNC:
Kufomula:
I-P - intambo yentambo noma intambo ye-workpiece, iyunithi: mm.
K - i-coefficient yomshuwalense, ngokuvamile engu-80.
Ukubalwa kokujula kokuphakelayo ngakunye kochungechunge lomshini
Inombolo yezindlela zamathuluzi okuthunga
1) Ukwenza imishini enzima
Ifomula yokubala enamandla yokuphakelayo komshini rough: f rough=0.5 R
Kuphi: R ------ ithiphu yethuluzi i-arc radius mm
F ------ okuphakelayo kwethuluzi lomshini olukhuni mm
2) Ukuqeda
Kufomula: Rt ------ ukujula kwekhonta µ m
F ------ Isilinganiso sokuphakelayo mm/r
r ε ------ Irediyasi yethiphu yamathuluzi arc mm
Hlukanisa ukujika okumaholo nokuqeda ngokwezinga lokuphakelayo kanye nomsele wokuqhekeka kwe-chip
F ≥ 0.36 machining rough
0.36 ＞ f ≥ 0.17 ukuqeda kancane
F ＜ 0.17 qeda ukwenza imishini
Akuyona into yensingo kodwa i-chip-breaking groove ethinta umshini onzima futhi ophelile we-blade. Unqenqema lokusika lubukhali uma i-chamfer ingaphansi kwama-40um.
