1. Khetha amapharamitha wejometri ethuluzi
Lapho insimbi yensimbi engenacala, iJiyomethri yengxenye yokusika yethuluzi kufanele icatshangwe ngokukhethwa kwe-bake angle ne-angle emuva. Lapho ukhetha i-rake angle, izici ezinjengephrofayela umtshingo, ukuba khona noma ukungabikho kokuhlangana nokuhlangana okuhle nokubi kokuthambekela kwe-blace kufanele kubhekwe. Akunandaba nethuluzi, kufanele kusetshenziswe i-bacle engela enkulu lapho insimbi engagqwali. Ukwandisa i-rake engela yethuluzi kunganciphisa ukumelana okuhlangane nakho ngesikhathi sokusika kwe-chip nokuhlanza. Ukukhethwa kwe-angle yemvume akuqinile, kepha akufanele kube kuncane kakhulu. Uma i-angle yokuvunyelwa incane kakhulu, izodala ukungqubuzana okukhulu ngobubanzi bokusebenza, kukhulisa ubulukhuni bendawo ebekiwe kanye nokusheshisa ithuluzi lokugqoka. Futhi ngenxa yokungqubuzana okunamandla, umphumela wokuqina kwensimbi engagqwali kuyathuthukiswa; I-angle yokuvunyelwa kwamathuluzi akufanele ibe nkulu kakhulu, inkulu kakhulu, ukuze i-wedge angle yethuluzi incishisiwe, amandla onqenqemeni onqenqemeni ancishisiwe, futhi ukugqokwa kwethu kusheshiswa. Ngokuvamile, i-angle yokusiza kufanele ibe yinkulu kakhulu kunanini lapho icubungula insimbi evamile yekhabhoni.
Ukukhethwa kwe-bake angle kusuka esicini sokusika isizukulwane sokushisa kanye nokuhlanza ukushisa, ukukhulisa i-rake engela kunganciphisa kakhulu, futhi uma ivolumu yokusika likhulu kakhulu, futhi uma ivolumu yokusika likhulu kakhulu, futhi ivolumu yokushisa yethimba le-TOOL izokwehla, futhi izinga lokushisa lokusika lizophela. Ephakanyisiwe. Ukunciphisa i-bacle angle kungathuthukisa izimo zokuhlanza ukushisa kwekhanda le-cutter, futhi izinga lokushisa elisikiwe lingancipha, kepha uma i-cake angle incane kakhulu, ukushisa okushintshiwe kuzoba ngokungathi sína, futhi ukushisa okukhiqizwayo ngeke kuhlakazeke kalula. Prakthiza kukhombisa ukuthi i-rake angle Go = 15 °-20 ° iyona efaneleke kakhulu.
Lapho ukhetha i-angle yemvume yemishini enolaka, amandla okusika onqenqemeni wamathuluzi anamandla okusika kudingeka aphakame, ngakho-ke kufanele kukhethwe i-angle elincanyana. Ngesikhathi sokuqeda, ithuluzi lokugqoka ikakhulukazi livela endaweni enqenqemeni lokusika kanye ne-flank ebusweni. Insimbi engenasici, impahla ethambekele ekusebenzeni kanzima, inomthelela omkhulu ekhwalithi ephezulu kanye nokugqoka kwamathuluzi okubangelwa ukungqubuzana kwe-flank. I-angle yokusiza okufanele ibe yinto: ngensimbi engenzi lutho (ngaphansi kwe-185hb), i-angle yokusiza ingaba ngu-6 ° - -8 °; Ukucutshungulwa kwensimbi engenacala ngokungenacala (ngenhla kwe-250HB), i-angle yokuvunyelwa yi-6 ° -8 °; Insimbi engenacala ngokugqekeza (ngezansi kwe-250hb), i-angle yokuvunyelwa yi-6 ° -10 °.
Ukukhethwa kwe-angle ethambisa i-angle ngosayizi nokuqondisa kwe-angle yokuthambekela kwe-blade kunquma ukuqondiswa kokugeleza kwe-chip. Ukukhetha okunengqondo kwe-angle yokuthambisa i-angle ls kuvame - 10 °-20 °. Kufanele kusetshenziswe amathuluzi amakhulu okuthambisa amabala lapho kuqeda i-micro mbuthano, izimbobo eziguqukayo ezinhle, nezindiza ezinhle kakhulu: I-LS45 ° -75 ° kufanele isetshenziswe.
2. Ukukhetha kwezinto zethuluzi
Lapho kucutshungulwa insimbi engenacala, umnikazi wamandla kufanele ube namandla anele nokuqina ngenxa yamandla amakhulu wokusika ukugwema ukuphambukiswa kanye nokuguquguquka ngesikhathi senqubo yokusika. Lokhu kudinga ukukhethwa kwendawo enkulu yesigaba esiyisisekelo somnikazi wamathuluzi, kanye nokusetshenziswa kwezinto ezinamandla amakhulu ukwenza umnikazi wamathuluzi, njengokusetshenziswa kwensimbi ecijile nenomoya we-50.
Izidingo zengxenye yokusika yethuluzi lapho zicubungula insimbi engenacala, okuqukethwe kwengxenye yokusika yethuluzi kuyadingeka ukuba ube nokuvimbela okuphezulu futhi kugcinwe ukusebenza kwayo kokusika endaweni ephakeme. Izinto ezisetshenziswa kakhulu njengamanje yilezi: Insimbi esheshayo ne-carbide enomthwalo. Ngoba insimbi enesivinini esiphakeme ingagcina ukusebenza kwayo kokusika kuphela ngaphansi kwama-600 ° C, ayilungele ukusika okusheshayo, kepha ilungele ukucubungula insimbi engagqwali ngejubane eliphansi. Ngenxa yokuthi i-carbide enesihlahla evuthiwe inokumelana okungcono kokushisa futhi igqoke ukumelana kunensimbi enesivinini esikhulu, amathuluzi enziwe ngezinto ze-carbide ezihleliwe zilungele ukusika insimbi engagqwali.
I-Carbide efakwe ngesiqeshana ihlukaniswe izigaba ezimbili: I-Tungsten-Cobalt Alloy (YG) neTungsten-Cobalt-Titanium Alloy (YT). I-Tungsten-Cobalt Alloys inobunzima obuhle. Amathuluzi enziwe angasebenzisa i-bacle engela enkulu kanye nomphetho obukhali ukuze ugaye. Ama-chip kulula ukumane aqhamuke ngesikhathi senqubo yokusika, futhi ukusika kushubile. Ama-chips akulula ukunamathela ethubeni. Kulokhu, kufanelekile kakhulu ukucubungula insimbi engagqwali ngeTungsten-Cobalt Alloy. Ikakhulu emishini enokhahlo kanye nokusika okuhlangene nokudlidliza okukhulu, kufanele kusetshenziswe ama-alloy ama-alloy amaningi. Akunzima futhi i-brittle njenge-tungsten-cobalt-titanium alloy, akulula ukucija, futhi kulula ukuyisebenzisa. I-Tungsten-Cobalt-Titanium Alloy inobunzima obubomvu obungcono futhi igqoke kakhulu kuneTungsten-Cobalt Alloy ngaphansi kwezimo eziphakeme zokushisa, kepha i-brittle kakhulu, hhayi ukumelana nomthelela nokudlidliza, futhi ngokuvamile isetshenziswa njengethuluzi lokujika kwensimbi engagqwali.
Ukusebenza kokusika kokuqukethwe kwamathuluzi kuhlobene nokuqina kanye nokukhiqiza ithuluzi, kanye nokwakhiwa kwezinto zethuluzi kuthinta ukukhiqiza kanye nekhwalithi elolayo yethuluzi uqobo. Kungcono ukuthi ukhethe izinto zethuluzi ngobulukhuni obuphezulu, ukumelana okuhle nokumelana, okungcono kakhulu hhayi ukucubungula i-ty hard alloy auntenitic, ngoba kufanelekile ukusebenzisa i-y hard alloy alloy, ngoba i-titanium (TI Ubumbano, ama-chips angasusa kalula i-TI ku-alloy, ekhuthaza ukugqokwa kwethuluzi lokugqoka. Ukusebenza Kwemikhiqizo kukhombisa ukuthi ukusetshenziswa kwe-YG532, YG813 kanye ne-YW2 amamaki amathathu wezinto zokwakha ukucubungula insimbi engagqwali inomphumela omuhle wokucubungula inethonya elihle
3. Ukukhetha inani lokusika
Ukuze ucindezele isizukulwane somandlakhelwe owakhelwe amandla futhi uthuthukise ikhwalithi ephezulu, lapho ucubungula ngamathuluzi we-carbide ahlanganisiwe, ikakhulukazi isivinini sokusika akufanele siphakanyiswe kakhulu, ijubane lokusika lincono kakhulu, i-cutting speed ap = 4--7mm, kanye nesilinganiso sokudla f = 0.15-0-0.6mm / r.
I-4. Izidingo zobulukhuni bendawo yokusika yetini
Ukuthuthukisa ukuqeda okungaphezulu kwengxenye yokusika yethuluzi kunganciphisa ukumelana lapho ama-chip agobile futhi athuthukise ukuqina kwethuluzi. Qhathanisa nokwenza insimbi ephathekayo evamile yekhabhoni, lapho icubungula insimbi engenacala, inani lokusika kufanele lincishiswe ngokufanele ukuze linciphise ukugqokwa kwethuluzi; Ngasikhathi sinye, kukhethwe ukupholisa okufanele futhi kukhethwe uketshezi olufanele lokunciphisa ukushisa nokusika ngesikhathi senqubo yokusika, futhi kwandise impilo yenkonzo yethuluzi.
