Ukunemba kusetshenziselwa ukukhombisa ubuhle bomkhiqizo we-workpiece. Kuyitemu elikhethekile lokuhlola imingcele yejometri yendawo yomshini kanye nenkomba ebalulekile yokulinganisa ukusebenza kwezikhungo zemishini ye-CNC. Ngokuvamile, ukunemba komshini kukalwa ngebanga lokubekezelelana. Ibanga eliphansi, liphezulu ukunemba. Ukuphenduka, ukugaya, ukuhlela, ukugaya, ukubhoboza, kanye nesicefe kuyizindlela ezivamile zokulungisa izikhungo zemishini ye-CNC. Ngakho-ke yikuphi ukunemba komshini okufanele lezi zinqubo zomshini zifeze?
1.Ukunemba kokuguqula
Ukuphenduka kusho inqubo yokusika lapho i-workpiece izungeza futhi ithuluzi eliphendukayo lihamba ngendlela eqondile noma ijika endizeni, elisetshenziselwa ukucubungula indawo yangaphakathi nengaphandle ye-cylindrical, ubuso bokuphela, indawo eyi-conical, ukwakha izindawo kanye nemicu ye-cylindrical. umsebenzi.
Ubukhulu obuphezulu bokuphenduka bungu-1.6-0.8μm.
Ukuphenduka okungalungile kudinga ukusetshenziswa kokujula okukhulu kokusika kanye nezinga elikhulu lokuphakela ukuze kuthuthukiswe ukusebenza kahle kokuphenduka ngaphandle kokunciphisa isivinini sokusika, futhi imfuneko yobunzima obungaphezulu bungama-20-10um.
Amathuluzi e-Xinfa CNC anezici zekhwalithi enhle nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bamathuluzi E-CNC - Imboni Yamathuluzi Yase-China CNC Nabahlinzeki Bempahla (xinfatools.com)
Ukuqeda kancane nokuqeda ukuphenduka zama ukusebenzisa isivinini esikhulu kanye nezinga lokuphakelayo elincane kanye nokujula kokusika, futhi ubuhwaqane obungaphezulu bungu-10-0.16um.
Ithuluzi lokujika ledayimane elipholishelwe kahle elenziwe ngensimbi elinembe kakhulu lingaphendula izinto zokusebenza zensimbi ezingenayo ayoni ngesivinini esikhulu, ngobuhhadlahhadla obungaphezulu obungu-0.04-0.01um. Lolu hlobo lokuphenduka lubizwa nangokuthi "i-mirror turning".
2. Ukugaya ngokunemba kokugaya kubhekisela ekusetshenzisweni kwamathuluzi azungezayo anama-blade amaningi ukuze asike izingcezu zokusebenza, okuyindlela esebenza kahle kakhulu yokucubungula.
Ifanele ukucubungula izindiza, ama-grooves, nama-splines ahlukahlukene, amagiya, isikhunta sezintambo nezinye izindawo ezikhethekile.
Ubulukhuni obungaphezulu bokugaya ngokuvamile bungu-6.3-1.6μm. Ubulukhuni obungaphezulu bokugaya ama-rough 5-20μm.
Ubulukhuni obungaphezulu be-semi-finishing milling buyi-2.5-10μm. Ubukhulu obuphezulu bokugaya kahle buyi-0.63-5μm.
3. Ukunemba kokuhlela
Ukuhlela kuyindlela yokusika esebenzisa iplanethi ukwenza umnyakazo ovundlile ohambisanayo ohambisanayo endaweni yokusebenza, esetshenziselwa ikakhulukazi ukucubungula umumo wezingxenye. Ubukhulu obuphezulu bepulani bungu-Ra6.3-1.6μm.
Ubukhulu obuphezulu bokuhlela ama-rough 25-12.5μm. Ubulukhuni obungaphezulu be-semi-finishing planing buyi-6.2-3.2μm. Ubulukhuni obungaphezulu be-fine planing buyi-3.2-1.6μm.
4. Ukunemba kokugaya Ukugaya kubhekisela endleleni yokucubungula yokusebenzisa ama-abrasives kanye namathuluzi okugaya ukuze kunqunywe izinto ezingaphezulu ku-workpiece. Ingokokucubungula kahle futhi isetshenziswa kakhulu embonini yokukhiqiza imishini.
Ukugaya kuvame ukusetshenziselwa ukuqeda kancane kanye nokuqeda, futhi ubulukhuni obungaphezulu buvamise ukuba ngu-1.25-0.16μm.
Ubulukhuni obungaphezulu bokugaya ngokunemba buyi-0.16-0.04μm.
Ubulukhuni obungaphezulu bokugaya okunembe kakhulu ngu-0.04-0.01μm. Ubulukhuni obungaphezulu bokugaya isibuko bungafinyelela ngaphansi kuka-0.01μm.
5. Kuyabhora
Kuyinqubo yokusika esebenzisa ithuluzi lokwandisa ububanzi bangaphakathi bembobo noma enye i-contour eyindilinga. Ububanzi bokusebenza kwayo ngokuvamile busukela ku-semi-roughing kuye ekuqedeni. Ithuluzi elisetshenziswayo livamise ukuba yithuluzi eliyisicefe elinomphetho owodwa (elibizwa ngokuthi ibha eyisicefe).
Ukunemba okuyisicefe kwezinto zensimbi ngokuvamile kungafinyelela ku-2.5-0.16μm.
Ukunemba kokucubungula kokunemba okuyisicefe kungafinyelela ku-0.63-0.08μm.
