Ukunemba kusetshenziselwa ukuveza ubuhle bomkhiqizo we-workpiece. Kuyitemu elikhethekile lokuhlola imingcele yejiyomethri yendawo eyenziwe ngomshini. Futhi kuyinkomba ebalulekile yokulinganisa ukusebenza kwezikhungo zemishini ye-CNC. Ngokuvamile, ukunemba komshini kukalwa ngamaleveli okubekezelela. Izinga eliphansi, liphezulu ukunemba. Ukuphenduka, ukugaya, ukuhlela, ukugaya, ukubhoboza, kanye nesidina kuyizindlela ezijwayelekile zokucubungula zezikhungo zemishini ye-CNC. Ngakho yikuphi ukunemba kokucubungula okufanele lezi zinqubo zokucubungula kufezeke?
1.Ukunemba kokuguqula
Ukuphenduka kusho inqubo yokusika lapho ucezu lokusebenza luzungeza futhi ithuluzi elijikayo lihamba ngokulandelana noma ngokugobile endizeni ukuze kucutshungulwe indawo yangaphakathi nengaphandle yamacylindrical, ubuso bokuphela, ubuso obuyi-conical, ukwakha izindawo kanye nemicu ye-workpiece.
Ubukhulu obuphezulu bokuphenduka bungu-1.6-0.8μm.
Ukuphenduka okungalungile kudinga ukusetshenziswa kokujula okukhulu kokusika kanye nesilinganiso esikhulu sokuphakelayo ukuze kuthuthukiswe ukusebenza kahle kokuphenduka ngaphandle kokunciphisa isivinini sokusika. Ubukhulu obuphezulu kufanele bube ngu-20-10um.
Ukuze uqedele kancane futhi uqedele ukuphenduka, zama ukusebenzisa isivinini esikhulu kanye nokuphakelayo okuncane nokujula kokusika, futhi ukuhwaqeka kwendawo kungu-10-0.16um.
Amathuluzi okuguqula idayimane eliphansi asetshenziswa kumalethe anembe kakhulu ukuze aqedele ukuphendukisa izinto zokusebenza zensimbi ezingenayo ayoni ngesivinini esikhulu ngobuhwaqane obungaphezulu obungu-0.04-0.01um. Lolu hlobo lokuphenduka lubizwa nangokuthi "i-mirror turning".
Amathuluzi e-Xinfa CNC anezici zekhwalithi enhle nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:

2. Ukunemba kokugaya
Ukugaya kusho ukusetshenziswa kwamathuluzi ajikelezayo anezinhlangothi eziningi ukusika izingcezu zokusebenza, futhi kuyindlela yokucubungula esebenza kahle kakhulu. Ifanele ukucubungula izindiza, ama-grooves, nezindawo ezikhethekile ezinjengama-splines, amagiya, nokukhunta okunentambo.
Ubukhulu obujwayelekile bobuso bokunemba kokucubungula ukugaya bungu-6.3-1.6μm.
Ubulukhuni obungaphezulu ngesikhathi sokugaya buyi-5-20μm.
Ubukhulu obuphezulu ngesikhathi sokugaya i-semi-finilling buyi-2.5-10μm.
Ubukhulu obuphezulu ngesikhathi sokugaya kahle buyi-0.63-5μm.
3.Ukunemba kokuhlela
Ukuhlela kuyindlela yokucubungula yokusika esebenzisa iplanethi ukwenza ukunyakaza okuvumelanayo okuvundlile kanye nomugqa endaweni yokusebenza. Ngokuyinhloko isetshenziselwa ukucubungula isimo sezingxenye.
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 kusho indlela yokucubungula esebenzisa ama-abrasives namathuluzi abrasive ukuze kukhishwe izinto ezidingekayo emsebenzini. Kuyinqubo yokuqeda futhi isetshenziswa kabanzi embonini yokukhiqiza imishini.
Ukugaya kuvame ukusetshenziselwa ukuqeda kancane kanye nokuqeda, futhi ubulukhuni obungaphezulu buvamise ukuba ngu-1.25-0.16μm. Ukunemba kobuso bokugaya bungu-0.16-0.04μm.
Ubulukhuni obungaphezulu bokugaya okunembe kakhulu ngu-0.04-0.01μm.
Ubukhulu obuphezulu bokugaya isibuko bungafinyelela ngaphansi kuka-0.01μm.
5. Kuyisicefe futhi kuyisicefe
Kuyinqubo yokusika i-diameter yangaphakathi esebenzisa ithuluzi lokukhulisa imbobo 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.
