Abasiki bokugaya baziwa nangokuthi izingcezu zokugaya, amathuluzi okugaya, kunezinhlobo ezahlukene zabasiki bokugaya. Abanye abasiki bangasetshenziselwa imisebenzi eminingi, abanye bangasetshenziselwa inqubo eyodwa kuphela. Abanye abasiki banamazinyo angama-helical, abanye banamazinyo aqondile. Abanye abasiki banezimbobo ezifakwayo, abanye banamashanki afakwayo. Umsebenzisi womshini wokugaya we-CNC udinga ukunquma ukuthi yisiphi isisiki azosisebenzisa. Ukwenza lokhu kukhetha, kufanele wazi ngezinhlobo eziningi zabasiki kanye nokusetshenziswa kwazo.
Izinhlobo eziyi-11 ze-CNC Milling Cutter
1. I-Plain Milling Cutters.
2. Metal Slitting Saw Milling Cutters.

4. Qeda Ama-Milling Cutters.
5. Ama-Face Milling Cutters.
6. T-Slot Milling Cutters.
7. Woodruff Keyslot Milling Cutters.
8. Ama-Angle Milling Cutters.
9. I-Concave ne-Convex Milling Cutters.
10. Ama-Milling Cutters ajikeleza ekhoneni.
11. I-Gear Hob (Izisiki Zokugaya Izinyo Ezakhiwe).
8 Izinyathelo Ukukhetha CNC Milling Cutters.
Izinto ezilandelayo kufanele zibhekwe ekukhetheni amathuluzi okugaya:
1. Uhlobo Lomshini Ozosetshenziswa.
Izisiki zensimbi ezinesivinini esikhulu, i-stellite, kanye ne-cemented carbide zinenzuzo ehlukile yokukwazi ukukhiqiza ngokushesha uma zisetshenziswa emshinini ongafinyelela isivinini esifanele.
2. Ukuqina Kwezinto Ezizosikwa.
Ukuqina kwezinto ezibonakalayo, okukhulu kuzoba ukushisa okukhiqizwa ngesikhathi sokusika. Abasiki kufanele bakhethelwe izakhiwo zabo ezivimbela ukushisa.
3. Ikilasi Lomsebenzi Owenziwayo.
Eminye imisebenzi ingafezwa ngohlobo olungaphezu kolulodwa lokusika, njengokugaywa kokuphela kwesikwele ku-shaft noma shank ye-reamer. Kulesi simo, kungasetshenziswa izingcezu zokugaya eziseceleni eyodwa noma ezi-2 noma i-end milling cutter. Kodwa-ke, emisebenzini eminingi, abasiki baklanywe ngokukhethekile futhi baqanjwe ngomsebenzi okufanele bawenze.
4. Indlela Yokusonga I-Workpiece.
Ngokwesibonelo, 45° ukusikeka kwe-angular kungase kwenziwe nge 45° ithuluzi lokugaya eline-engeli eyodwa ngenkathi ucezu lokusebenza lubanjwe nge-vise ejikayo, noma ngesisiki sokugaya ngenkathi ucezu lokusebenza lusethwe nge-engeli edingekayo ku-vise yendawo yonke.
5. Inani Lezingcezu Ezizosikwa.
Isibonelo, uma isitokwe sokugaya sifinyelela ubude, ukukhetha kokusebenzisa abasiki bezinhlangothi ukuze baxazulule ucezu lokusebenza, ithuluzi lokugaya elinohlangothi olulodwa, noma i-end milling cutter kuzoncika enanini lezingcezu ezizosikwa.
6. Inani Lempahla Ezokhishwa.
Isisiki sokugaya esinamazinyo esifundo kufanele sisetshenziselwe ukusikeka okugoqayo, kanti umshini wokugaya onamazinyo amahle angase asetshenziselwe ukusikeka okulula nokuqedela imisebenzi.
7. Usayizi Wesisiki Sokugaya.
Ekukhetheni ithuluzi lokugaya lomsebenzi othile, kufanele kukhunjulwe ukuthi i-diameter encane yokusika izodlula endaweni ngesikhathi esifushane kune-diameter cutter enkulu ephakelwa ngesivinini esifanayo.
8. Ukuqina kanye Nobukhulu Bomsebenzi.
Ithuluzi lokugaya elisetshenzisiwe kufanele libe lincane ngokwanele ububanzi ukuze ukucindezela kokusika kungeke kubangele ukuba ucezu lokusebenza luqhume noma lususwe lapho lugaywa.
Amathiphu ayi-8 Okugcina I-CNC Milling Cutters.
Impilo ye-CNC milling cutter ingandiswa kakhulu ngokusetshenziswa okukhaliphile nokugcinwa okufanele. Imithetho ejwayelekile yokunakekelwa nokugcinwa kwamathuluzi okugaya inikezwe ngezansi:
1. Abasiki abasha abatholwa esitokisini bavame ukugoqwa ngephepha lamafutha okungafanele likhishwe kuze kusetshenziswe umsiki.
2. Kufanele kuqashelwe ukuvimbela i-putter ekushayeni imihlathi eqinile ye-vise, chuck, clamping bolts, noma amantongomane.
3. Noma nini lapho kungenzeka, uwoyela wokusika ofanele kufanele usetshenziswe kumsiki kanye nendawo yokusebenza ngesikhathi sokusebenza, njengoba ukugcoba kusiza ukuvimbela ukushisa ngokweqile kanye nokugqoka kwe-cutter okulandelayo.
4. Ama-cutters kufanele afakwe emakhabetheni noma emigqonyeni ngendlela yokuthi ama-cutter awo angeke ashayisane. Abasiki abancane abanembobo phakathi nendawo kufanele baphanyekwe ezingwegweni noma ezikhonkwaneni, abasiki abakhulu kufanele bamiswe ekugcineni. Abasiki be-shank abacijile nabaqondile bangase babekwe emakhabetheni ahlukene, imigqomo, noma ama-rack anikezwe izimbobo ezinobukhulu obufanele ukuthola ama-shanks.
5. Ama-Cutters kufanele agcinwe ebukhali, ngoba ama-cutters angenalutho adinga amandla amaningi okuwaqhuba futhi la mandla, aguqulwa abe ukushisa, athambisa imiphetho yokusika. Abasiki ababuthuntu kufanele bamakwe kanjalo futhi babekelwe eceleni ukuze bagaywe.
6. Umsiki wokugaya kufanele uhlanzwe kahle futhi ugcotshwe kancane ngamafutha ngaphambi kokuwugcina.
7. Umsiki akufanele neze asetshenziswe emuva ngoba, ngenxa ye-engeli yokususa, umsiki uzohlikihla, akhiphe ukushisa okukhulu okushayisanayo. Ukusebenzisa i-cutter emuva kungase kubangele ukuphuka kwe-cutter.
8. Kufanele kuqikelelwe ukusebenzisa umshini ngesivinini esifanelekile sesisiki esisetshenziswayo; ijubane elidlulele lizokwenza ukuthi umsiki agqoke ngokushesha kusuka ekushiseni ngokweqile.
Isiphetho
Izingcezu zokugaya zidlala indima ebalulekile ekwenzeni imisebenzi yomshini wokugaya. Ukwazi ukuthi iyiphi i-cutter okufanele uyikhethe futhi uyisebenzise ekusebenzeni okuthile, kwesinye isikhathi, kuyonquma ikhwalithi iyonke yomkhiqizo wokugcina. Ulwazi oluzuzwe kulo msebenzi mayelana nezingcezu zokugaya luzokusiza ekunqumeni uhlobo lom(aba)siki (abasiki) ozowasebenzisa emsebenzini othize, okufaka i-nomenclature, ukukhetha, ukusetshenziswa nokunakekelwa kwezingcezu zokugaya lapho unikezwe umsebenzi wokwenza imisebenzi yomshini wokugaya.
