Ulwazi lwe-Tungsten Carbide End Mills kanye Nezimo Zazo Zokuhluleka okungenzeka

Ingabe izigayo zokugcina zenziwe nge-carbide?

Izigayo eziningi zokugcina zenziwa kusukela ku-cobalt steel alloys - okubizwa ngokuthi i-HSS (I-High Speed ​​Steel), noma kusuka ku-tungsten carbide. Ukukhethwa kwempahla yesigayo sakho sokuphela esikhethiwe kuzoncika ebulukhunini bomsebenzi wakho kanye nesivinini esikhulu sokuphotha somshini wakho.

Isiphi isigayo esinzima kunazo zonke?

Izigayo zokugcina zeCarbide.

Izigayo zeCarbide zingenye yamathuluzi okusika anzima kakhulu atholakalayo. Eduze kwedayimane kunezinye izinto ezimbalwa eziqinile kune-carbide. Lokhu kwenza i-carbide ikwazi ukwenza cishe noma iyiphi insimbi uma yenziwe ngendlela efanele. I-Tungsten Carbide iwela phakathi kuka-8.5 no-9.0 esikalini sokuqina sika-Moh, okuyenza icishe iqine njengedayimane.

Iyiphi into engcono kakhulu yokugaya insimbi?

Ngokuyinhloko, izigayo zokuphela kwe-carbide zisebenza kangcono kakhulu ngensimbi nama-alloys ayo ngoba inokuhamba okushisayo okuningi futhi isebenza kahle ezinsimbi eziqinile. I-Carbide iphinde isebenze ngesivinini esiphezulu, okusho ukuthi isisiki sakho singakwazi ukumelana namazinga okushisa aphezulu futhi singavimbela ukuguga nokudabuka ngokweqile. Lapho uqeda izingxenye zensimbi engagqwali, ukubala okuphezulu komtshingo kanye/noma i-helix ephakeme kuyadingeka ukuze kube nemiphumela emihle kakhulu. Ukuqeda izigayo zensimbi engagqwali kuzoba ne-engeli ye-helix engaphezu kwamadigri angu-40, kanye nokubala komtshingo okungu-5 noma ngaphezulu. Ukuze uthole izindlela zamathuluzi okuqeda ezinolaka, ukubala komtshingo kungasukela kuma-flute angu-7 kuye phezulu kuye ku-14.

Yikuphi okungcono, HSS noma carbide ekupheleni Mills?

I-Solid Carbide inikeza ukuqina okungcono kune-high-speed steel (HSS). Ikwazi ukumelana nokushisa ngokwedlulele futhi isetshenziselwa ukufakwa kwesivinini esikhulu kunsimbi ewugqinsi, izinto ezingezona insimbi, amapulasitiki nezinye izinto ezisebenza kanzima emshinini. Izigayo zokuphela kwe-Carbide zinikeza ukuqina okungcono futhi zingaqhutshwa ngokushesha okungu-2-3X kune-HSS.

Kungani izigayo zokugcina zihluleka?

1. Ukuyigijima Kakhulu Noma Kancane KakhuluIngathinta Impilo Yethuluzi.

Ukusebenzisa ithuluzi ngokushesha kakhulu kungabangela usayizi we-chip ongekho olungile noma ukwehluleka kwethuluzi okuyinhlekelele. Ngokuphambene, i-RPM ephansi ingaholela ekuphambukeni, ekuqedeni okubi, noma ekwehleni kwamazinga okususwa kwensimbi.

2. Ukuyondla Kancane Kakhulu Noma Kakhulu.

Esinye isici esibalulekile sesivinini nokuphakelayo, izinga lokuphakelayo elingcono kakhulu lomsebenzi liyahlukahluka kakhulu ngohlobo lwamathuluzi nezinto zokusebenza. Uma usebenzisa ithuluzi lakho ngesilinganiso sokuphakela esinensa kakhulu, usengozini yokusika kabusha ama-chips nokusheshisa ukuguga kwamathuluzi. Uma usebenzisa ithuluzi lakho ngokushesha okukhulu kwezinga lokuphakelayo, ungabangela ukuphuka kwethuluzi. Lokhu kuyiqiniso ikakhulukazi ngokusetshenziswa kwamathuluzi amancane.

3. Ukusebenzisa I-Traditional Roughing.

Nakuba ukugoqa okungokwesiko kudingekile ngezikhathi ezithile noma kulungile, ngokuvamile kungaphansi kune-High Efficiency Milling (HEM). I-HEM iwuhlelo oluqinile olusebenzisa i-Radial Depth of Cut (RDOC) kanye ne-Axial Depth of Cut (ADOC). Lokhu kusabalalisa ukuguga ngokulinganayo kuwo wonke umkhawulo wokusika, kuqeda ukushisa, futhi kunciphisa ithuba lokuhluleka kwamathuluzi. Ngaphandle kokukhulisa ngokumangazayo impilo yamathuluzi, i-HEM ingaphinda ikhiqize isiphetho esingcono kanye nezinga eliphezulu lokususwa kwensimbi, ikwenze kube umfutho ozungezile osebenza kahle esitolo sakho.

4. Ukusebenzisa Ukubamba Ithuluzi Okungafanele kanye Nomphumela Wako Ekuphileni Kwamathuluzi.

Amapharamitha asebenzayo anomthelela omncane ezimeni zokubamba ithuluzi eliphansi. Ukuxhumeka okungalungile komshini nethuluzi kungabangela ukuphela kwethuluzi, ukuphuma, nezingxenye ezilahliwe. Ngokuvamile, amaphuzu amaningi okuxhumana umnikazi wamathuluzi aba nawo ne- too l's shank, yilapho uxhumano luvikeleke kakhulu. Izibambi zamathuluzi alingana ne-hydraulic kanye ne-shrink fit zinikeza ukusebenza okwengeziwe kunezindlela zokuqinisa imishini, njengoba kwenza izinguquko ezithile ze-shank.

5. Ukungasebenzisi i-variable Helix/Pitch Geometry.

Isici ezinhlobonhlobo zezigayo zokugcina zokusebenza okuphezulu, i-helix eguquguqukayo, noma iphimbo eliguquguqukayo, i-geometry iwushintsho olucashile ku-standard end mill geometry. Lesi sici sejiyomethri siqinisekisa ukuthi izikhawu zesikhathi phakathi koxhumene nabo onqenqemeni lomsebenzi ziyahlukahluka, kunokuba ngesikhathi esisodwa nokuzungezisa ithuluzi ngalinye.Lokhu kuhluka kunciphisa ukuxoxa ngokunciphisa i-harmonics, okwandisa impilo yamathuluzi futhi kukhiqize imiphumela ephezulu.

6. Ukukhetha I-Coating Engalungile Ungagqoka Ekuphileni Kwamathuluzi.

Naphezu kokumba eqolo kancane, ithuluzi eline-coating elungiselelwe impahla yakho yokusebenza lingenza umehluko. Izembatho eziningi zandisa ukuthambisa, zinciphisa ukugqokwa kwamathuluzi emvelo, kanti ezinye zandisa ubulukhuni nokumelana nemihuzuko. Kodwa-ke, akuwona wonke ama-coatings afaneleka kuzo zonke izinto zokwakha, futhi umehluko ubonakala kakhulu ezintweni ezinsimbi nezingenayo insimbi. Isibonelo, i-Aluminium Titanium Nitride (AlTiN) enamathelayo inyusa ubulukhuni nokumelana nezinga lokushisa ezintweni ezisansimbi, kodwa inokusondelana okuphezulu ne-aluminium, okubangela ukunamathela kwengxenye yomsebenzi ethuluzini lokusika. Ngakolunye uhlangothi, i-Titanium Diboride (TiB2) enamathelayo inobudlelwano obuphansi kakhulu ne-aluminium, futhi ivimbela ukusika ukwakheka nokupakishwa kwe-chip, futhi inweba impilo yamathuluzi.

7. Ukusebenzisa Ubude Obude Bokusika.

Nakuba ubude obude bokusika (LOC) budingeka ngempela kweminye imisebenzi, ikakhulukazi ekuqedeni imisebenzi, kunciphisa ukuqina namandla ethuluzi lokusika. Njengomthetho ojwayelekile, i-LOC yethuluzi kufanele ibe yinde kuphela njengoba idingeka ukuze kuqinisekiswe ukuthi ithuluzi ligcina ingxenye yalo yokuqala eningi ngangokunokwenzeka. Lapho i-LOC yethuluzi iba ende kulapho iba lula khona ekuphambukeni, bese kuncipha impilo yamathuluzi asebenzayo futhi kwandise ithuba lokuphuka.

8. Ukukhetha Ukubala Komtshingo Okungalungile.

Njengoba kubonakala kulula, isibalo somtshingo wethuluzi sinomthelela oqondile futhi ophawulekayo ekusebenzeni kwawo kanye namapharamitha asebenzayo. Ithuluzi elinenani eliphansi lomtshingo (2 kuya ku-3) linezigodi zomtshingo ezinkulu kanye nengqikithi encane. Njenge-LOC, i-substrate encane esele ethuluzini lokusika, iyancipha futhi iqinile kancane. Ithuluzi elinenani eliphezulu lomtshingo (5 noma ngaphezulu) ngokwemvelo linomongo omkhulu. Nokho, izinga eliphezulu lomtshingo alihlali lingcono. Izibalo zomtshingo eziphansi zivame ukusetshenziswa ku-aluminiyamu nezinto ezingezona ayoni, ngokwengxenye ngenxa yokuthi ukuthamba kwalezi zinto kuvumela ukuguquguquka okwengeziwe kwamazinga akhuphukayo okususwa kwensimbi, kodwa nangenxa yezakhiwo zama-chips azo. Izinto ezingezona ayoni ngokuvamile zikhiqiza ama-chips amade, ama-stringier kanye nenani eliphansi lomtshingo kusiza ukunciphisa ukusika kabusha kwe-chip. Amathuluzi wokubala umtshingo ophezulu ngokuvamile ayadingeka ezintweni ezisansimbi eziqinile, kokubili ngenxa yamandla azo akhulayo futhi ngenxa yokuthi ukunqanyulwa kwe-chip akuyona into ekhathazayo njengoba lezi zinto zivame ukukhiqiza amashiphu amancane kakhulu.

Uma unentshisekelo ngemikhiqizo ye-tungsten carbide futhi ufuna imininingwane eyengeziwe nemininingwane, ungaXHUMANA NATHIngocingo noma ngeposi kwesokunxele, nomaSITHUMELE IMEYILIekugcineni kwaleli khasi.
