I-CNC lathe iyithuluzi lomshini ozenzakalelayo elinembayo, elisebenza kahle kakhulu. Ukusetshenziswa kwe-CNC lathe kungathuthukisa ukusebenza kahle kokucubungula futhi kudale inani elikhulu. Ukuvela kwe-CNC lathe kwenza amabhizinisi asuse ubuchwepheshe bokucubungula emuva. Ubuchwepheshe bokucubungula be-CNC lathe bufana, kodwa njengoba i-CNC lathe iwukubamba ngesikhathi esisodwa futhi ukucubungula okuzenzakalelayo okuqhubekayo kuqeda zonke izinqubo zokuphenduka, izici ezilandelayo kufanele zinakwe.
Ukukhetha okunengqondo kwenani lokusika
Ukusika kwensimbi okusebenza kahle kakhulu, izinto okufanele zicutshungulwe, amathuluzi okusika, nezimo zokusika ziyizici ezintathu ezinkulu. Lokhu kunquma isikhathi somshini, impilo yamathuluzi kanye nekhwalithi yomshini. Indlela yokucubungula eyongayo futhi ephumelelayo kufanele kube ukukhetha okunengqondo kwezimo zokusika.
Izakhi ezintathu zezimo zokusika: isivinini sokusika, izinga lokudla kanye nokujula kokusika kubangela ukulimala kwethuluzi. Ngokunyuka kwejubane lokusika, izinga lokushisa lephuzu lethuluzi lizokhuphuka, okuzobangela ukugqokwa kwemishini, amakhemikhali kanye nokushisa. Ijubane lokusika lenyuke ngo-20%, impilo yamathuluzi izoncishiswa ngo-1/2.
Ubudlelwano phakathi kwezimo zokuphakelayo nokugqokwa kwamathuluzi emuva kwenzeka phakathi kwebanga elincane kakhulu. Kodwa-ke, izinga lokudla likhulu, izinga lokushisa lokusika liyakhuphuka, futhi ukugqoka ngemuva kukhulu. Inomphumela omncane ethuluzini kunejubane lokusika. Nakuba umphumela wokujula kokusika ethuluzini awumkhulu njengejubane lokusika kanye nesilinganiso sokudla, lapho usikwa ngokujula okuncane kokusika, izinto ezizonqunywa zizokhiqiza ungqimba oluqinile, oluzophinde luthinte impilo ye ithuluzi.
Umsebenzisi kufanele akhethe isivinini sokusika azosisebenzisa ngokuya ngezinto okufanele zicutshungulwe, ubulukhuni, isimo sokusika, uhlobo lwezinto ezibonakalayo, isilinganiso sokuphakelayo, ukujula kokusika, njll.
Ukukhethwa kwezimo ezifanele kakhulu zokucubungula kukhethwa ngesisekelo salezi zici. Ukugqokwa okujwayelekile, okungaguquki kuze kube sekupheleni kwempilo kuyisimo esifanele.
Kodwa-ke, ekusebenzeni kwangempela, ukukhethwa kwempilo yamathuluzi kuhlobene nokugqoka kwamathuluzi, ukuguqulwa kosayizi, izinga eliphezulu, umsindo wokusika, ukushisa kokucubungula, njll. Lapho kunqunywa izimo zokucubungula, kuyadingeka ukwenza ucwaningo ngokuya ngesimo sangempela. Ezintweni ezinzima ukuya emshinini njengensimbi engagqwali kanye nama-alloys angashisi, isipholile singasetshenziswa noma unqenqema lokusika oluqinile lungasetshenziswa.
Indlela yokunquma izakhi ezintathu zokucubungula ukusika
Indlela yokukhetha kahle lezi zakhi ezintathu okuqukethwe okuyinhloko kwenkambo yesimiso sokusika insimbi. I-Metal processing WeChat ikhiphe amaphuzu athile abalulekile, kanye nezimiso eziyisisekelo zokukhetha lezi zici ezintathu:
(1) Isivinini sokusika (isivinini somugqa, isivinini se-peripheral) V (m/min)
Ukukhetha ukuguqulwa kokuphotha ngomzuzu, kufanele uqale wazi ukuthi isivinini somugqa wokusika V kufanele sibe singakanani. Ukukhethwa kwe-V: kuncike ezintweni zamathuluzi, impahla yokusebenza, izimo zokucubungula, njll.
Ithuluzi:
I-Carbide, V ingatholakala ephakeme, ngokuvamile engaphezu kuka-100 m/min, ngokuvamile ihlinzeka ngemingcele yezobuchwepheshe lapho uthenga izindwani:
Singakanani isivinini somugqa esingakhethwa lapho kucutshungulwa noma iyiphi into. Insimbi enesivinini esikhulu: V ingaba ngaphansi kuphela, ngokuvamile ingabi ngaphezu kuka-70 m/min, futhi ezimweni eziningi ingaphansi kuka-20-30 m/min.
Impahla yokusebenza:
Ubulukhuni obuphezulu, i-V ephansi; insimbi ephonsiwe, i-V ephansi, 70 ~ 80 m/min lapho impahla yamathuluzi iyi-carbide enosimende; insimbi ye-carbon ephansi, i-V ngaphezu kwe-100 m/min, insimbi engeyona insimbi, i-V ephakeme (100 ~ 200 m/min). Ngensimbi eqinile nensimbi engagqwali, u-V kufanele abe ngaphansi.
Izimo zokucubungula:
Ngomshini onzima, u-V kufanele abe ngaphansi; ngomshini omuhle, i-V kufanele ibe phezulu. Isistimu yokuqina yethuluzi lomshini, i-workpiece, nethuluzi ayilungile, futhi i-V kufanele ibe phansi. Uma i-S esetshenziswe kuhlelo lwe-NC iyinani lama-spindle revolutions ngomzuzu, khona-ke u-S kufanele abalwe ngokuvumelana nobubanzi be-workpiece kanye nesivinini somugqa wokusika V: S (ama-spindle revolutions ngomzuzu) = V (isivinini sokusika umugqa) * 1000 / (3.1416 * I-workpiece Diameter) Uma uhlelo lwe-NC lisebenzisa isivinini somugqa esingaguquki, khona-ke u-S angasebenzisa ngokuqondile isivinini esinqunyiwe somugqa V (m/min)
(2) Inani lokuphakelayo (inani elinqunyiwe)
U-F uncike kakhulu ezidingweni zobuhwaqane bobuso. Ekuqedeni imishini, imfuneko yendawo ephezulu iphezulu, futhi inani lokusika kufanele libe lincane: 0.06 ~ 0.12mm/spindle nge-revolution ngayinye. Lapho i-rough, kutuswa ukuba ibe nkulu. Ngokuyinhloko kuncike emandleni ethuluzi. Ngokuvamile, ingaphezu kuka-0.3. Uma i-angle yokusiza eyinhloko yethuluzi inkulu, amandla ethuluzi ampofu, futhi inani lokusika akufanele libe likhulu kakhulu. Ngaphezu kwalokho, amandla ethuluzi lomshini kanye nokuqina kwe-workpiece kanye nethuluzi kufanele kucatshangelwe. Uhlelo lwe-NC lusebenzisa amayunithi amabili wesilinganiso sokuphakela: mm/min, mm/spindle ngokuphenduka ngakunye, iyunithi esetshenziswa ngenhla ingu-mm/spindle ngokuphenduka ngakunye, uma kusetshenziswa i-mm/min, ifomula ingashintshwa: okuphakelayo ngomzuzu = ngakunye Okujikelezayo inani lokuphakelayo*ukuguqulwa kwe-spindle ngomzuzu
(3) Ukujula kokusika (ukujula kokusika)
Ekuqedeleni imishini, ngokuvamile ingaphansi kuka-0.5 (inani lerediyasi). Ngesikhathi somshini onzima, kuya ngezimo ze-workpiece, ithuluzi lokusika kanye nethuluzi lomshini. Ngokuvamile, ama-lathes amancane (ubukhulu obukhulu be-machining ububanzi obungaphansi kuka-400mm) aphendulela insimbi engu-No. 45 esimweni esijwayelekile, futhi ukujula kommese wokusika ohlangothini lwe-radial ngokuvamile akudluli u-5mm. Ngaphezu kwalokho, kufanele kuqashelwe ukuthi uma ijubane lokuphotha le-lathe lithatha ukulawulwa kwesivinini sokuguqulwa kwemvamisa ejwayelekile, lapho-ke ijubane lokuphotha ngomzuzu liphansi kakhulu (ngaphansi kuka-100 ~ 200 rpm), amandla okukhiphayo enjini azoba. kuncishiswe kakhulu. Ukujula kanye nenani lokuphakelayo kungatholakala kuphela kuncane kakhulu.
Ukukhetha okunengqondo kwemimese
1. Uma uphenduka obunzima, kuyadingeka ukukhetha ithuluzi elinamandla amakhulu kanye nokuqina okuhle, ukuze uhlangabezane nezidingo zomthamo omkhulu wokusika kanye nokudla okukhulu ngesikhathi sokuphenduka okunzima.
2. Lapho uqeda imoto, kuyadingeka ukukhetha ithuluzi ngokunemba okuphezulu nokuqina okuhle ukuze uqinisekise izidingo zokunemba kwemishini.
3. Ukuze kuncishiswe isikhathi sokushintsha ithuluzi futhi kube lula ukulungiselelwa kwamathuluzi, amathuluzi okubamba umshini nama-clamping blades kufanele asetshenziswe ngangokunokwenzeka.
Amathuluzi e-Xinfa CNC anekhwalithi enhle kakhulu nokuqina okuqinile, ukuze uthole imininingwane, sicela uhlole: https://www.xinfatools.com/cnc-tools/
Ukukhetha okunengqondo kwezinhlelo
1. Zama ukusebenzisa izinto ezisetshenziselwa inhloso evamile ukuze ubambe izinto zokusebenza, futhi ugweme ukusebenzisa izinto ezikhethekile;
2. Idatha yokubeka ingxenye ihambisana ukuze kuncishiswe iphutha lokuma.
Nquma umzila wokucubungula
Umzila wokucubungula ubhekisela endleleni yokunyakaza kanye nokuqondiswa kwethuluzi elihlobene nengxenye phakathi nenqubo yomshini wethuluzi lomshini we-CNC.
1. Kufanele ikwazi ukuqinisekisa ukunemba kwemishini kanye nezidingo zokuqina kwendawo;
2. Umzila wokucubungula kufanele ufinyezwe ngangokunokwenzeka ukuze kuncishiswe isikhathi sokuhamba sokungenzi lutho sethuluzi.
Ubudlelwano phakathi kokucubungula umzila nemvume yokucubungula
Okwamanje, ngaphansi kwesimo sokuthi i-CNC lathe ayikasetshenziswa kabanzi, ngokuvamile ukuvunyelwa okweqile endaweni engenalutho, ikakhulukazi imali equkethe izendlalelo zesikhumba esiqinile nezibunjiwe, kufanele zicutshungulwe ku-lathe evamile. Uma kufanele icutshungulwe nge-lathe ye-CNC, kufanele kuqashelwe ekuhlelweni okuguquguqukayo kohlelo.
Amaphuzu okufakwa kokulungisa
Njengamanje, ukuxhumana phakathi kwe-hydraulic chuck kanye nesilinda sokubamba amanzi kubonakala ngenduku yokudonsa. Amaphuzu asemqoka e-hydraulic chuck clamping ami kanje: okokuqala, sebenzisa isikrufu ukuze ususe inati kusilinda esidonsa amanzi, ukhiphe ishubhu lokudonsa, bese ulikhipha ekugcineni elingemuva le-shaft eyinhloko, bese usebenzisa isikrufu ukususa. i-chuck fixing screws ukususa i-chuck.
