Izici ze-milling cutter

Ama-Milling cuttersziza ngamajamo amaningana namasayizi amaningi. Kukhona nokukhethwa kwezingubo zokugqoka, kanye ne-rake angle kanye nenani lezindawo zokusika.

• Isimo:Izimo eziningana ezijwayelekile zeumsiki wokugayazisetshenziswa embonini namuhla, ezichazwe kabanzi ngezansi.
• Imitshingo / amazinyo:Imitshingo yebhithi yokugaya imigqa ejulile ye-helical egijima phezulu komsiki, kuyilapho i-blade ebukhali emaphethelweni omtshingo yaziwa ngokuthi izinyo. Izinyo lisika impahla, futhi ama-chips ale nto adonsela phezulu umtshingo ngokuzungezisa umsiki. Cishe njalo kukhona izinyo elilodwa ngomtshingo ngamunye, kodwa abanye abasiki banamazinyo amabili umtshingo ngamunye. Ngokuvamile, amazwiumtshingofuthiizinyozisetshenziswa ngokushintshana. Abasiki bokugaya bangase babe nezinyo ukusuka kwelilodwa kuye kwabaningi, kanti amabili, amathathu nane avame kakhulu. Ngokuvamile, uma umsiki enamazinyo engeziwe, yilapho ekwazi ukususa izinto ngokushesha. Ngakho, a4-izinyo lokusikaingasusa izinto ngesilinganiso esiphindwe kabili se-aumsiki wamazinyo amabili.
• I-Helix angle:Imitshingo yomshini wokusika acishe abe yi-helical. Uma imitshingo ibiqondile, izinyo lonke belingaba nomthelela ezintweni ngesikhathi esisodwa, libangele ukudlidliza nokunciphisa ukunemba kanye nekhwalithi ephezulu. Ukusetha imitshingo nge-engeli kuvumela izinyo ukuthi lingene kancane kancane, kunciphisa ukudlidliza. Ngokuvamile, abasiki abaqedayo bane-engeli ephezulu ye-rake (i-helix eqinile) ukuze banikeze isiphetho esingcono.
• Ukusika phakathi:Abanye abasiki bokugaya bangabhoboza baqonde phansi (bacwile) phakathi kwezinto, kuyilapho abanye bengakwazi. Lokhu kungenxa yokuthi amazinyo abanye abasiki awahambi yonke indlela eya enkabeni yobuso bokuphela. Nokho, laba basiki bangakwazi ukusika baye phansi nge-engeli engu-45 degrees noma ngaphezulu.
• Ukuhlukumeza noma ukuqeda:Izinhlobo ezahlukene zokusika ziyatholakala ukuze zisike inani elikhulu lezinto ezibonakalayo, zishiye isiphetho esingesihle (ukuhwashalaza), noma ukususa inani elincane lempahla, kodwa kushiye isiphetho esihle (ukuqeda).Umsiki onolakaingase ibe namazinyo amise okwephuka ama-chips ezinto zibe izingcezu ezincane. La mazinyo ashiya indawo emagebhugebhu ngemuva. Umsiki wokuqeda angase abe nenombolo enkulu (amazinyo amane noma ngaphezulu) okukhipha izinto ngokucophelela. Kodwa-ke, inani elikhulu lemitshingo lishiya indawo encane yokukhipha ama-swarf ngokuphumelelayo, ngakho-ke awafaneleki kakhulu ukususa inani elikhulu lezinto.
• Izigqoko:Izembatho zamathuluzi ezifanele zingaba nomthelela omkhulu enqubweni yokusika ngokwandisa isivinini sokusika kanye nempilo yamathuluzi, nokuthuthukisa ukuphela kwendawo. Idayimane ye-Polycrystalline (PCD) iyinalethi eqinile esetshenziswa kuyoabasikiokufanele imelane nokuguga okuphezulu. Ithuluzi elinamekwe nge-PCD lingahlala isikhathi esifika ku-100 kunethuluzi elingamboziwe. Kodwa-ke, ukugqoka akukwazi ukusetshenziswa emazingeni okushisa angaphezu kuka-600 degrees C, noma ezinsimbi ezinsimbi. Amathuluzi wokwenza i-aluminium ngezinye izikhathi anikezwa ukumbozwa kwe-TiAlN. I-Aluminium iyinsimbi enamathela ngokuqhathaniswa, futhi ikwazi ukuzishisela emazinyweni amathuluzi, iwabangele abonakale ebuthuntu. Kodwa-ke, ijwayele ukunganamatheli ku-TiAlN, ivumela ithuluzi ukuthi lisetshenziswe isikhathi eside ku-aluminium.
• I-Shank:I-shank ingxenye ye-cylindrical (non-fluted) yethuluzi esetshenziselwa ukubamba nokuyibeka endaweni yokuphatha ithuluzi. I-shank ingase ibe yindilinga ngokuphelele, futhi ibanjwe ukungqubuzana, noma ingaba ne-Weldon Flat, lapho isikulufu esisethiwe, esaziwa nangokuthi isikulufu se-grub, sithintana ne-torque eyengeziwe ngaphandle kokushelela kwethuluzi. Ububanzi bungase buhluke kububanzi bengxenye yokusika yethuluzi, ukuze bubanjwe umnikazi wamathuluzi ojwayelekile.§ Ubude be-shank bungase butholakale ngosayizi abahlukene, ngamashanki amafushane ngokuqhathaniswa (cishe 1.5x ububanzi) okuthiwa “i-stub”, yinde (ububanzi obuyi-5x), ubude obungeziwe (ububanzi obuyi-8x) nobude obengeziwe (ububanzi obuyi-12x).
