Izinhlobo zomtshingo:
Imitshingo ifaka imisele noma izigodi ezisikwe emzimbeni wethuluzi.Inombolo ephezulu yemitshingo inyusa amandla ethuluzi futhi inciphisa isikhala noma ukugeleza kwe-chip.Izigayo zokugcina ezinemitshingo emincane onqenqemeni lokusika zizoba nesikhala se-chip esengeziwe, kuyilapho izigayo ezinemitshingo eminingi zizokwazi ukusetshenziswa ezintweni zokusika eziqinile.
Umtshingo Wodwaimiklamo isetshenziselwa umshini wejubane eliphezulu kanye nokususwa kwempahla yevolumu ephezulu.
Imitshingo Emine/Eminingiimiklamo ivumela amazinga okuphakelayo asheshayo, kodwa ngenxa yesikhala somtshingo esincishisiwe, ukususwa kwe-chip kungase kube inkinga.Bakhiqiza isiphetho esihle kakhulu kunamathuluzi omtshingo amabili nantathu.Ilungele ukugaya nokuqeda.
Imitshingo Emibiliimiklamo inenani elikhulu lesikhala somtshingo.Avumela umthamo owengeziwe wokuthwala ama-chip futhi asetshenziswa ngokuyinhloko ekufakeni nasekufakeni ephaketheni izinto ezingashisi.
Umtshingo Ezintathuimiklamo inesikhala somtshingo esifanayo njengemitshingo emibili, kodwa futhi ibe nengxenye enkulu yesiphambano ukuze ibe namandla amakhulu.Asetshenziselwa ukufaka ephaketheni nasekufakeni izinto ezisansimbi nezingenayo i-ferrous.
Izinto Zethuluzi Lokusika:
I-High Speed Steel (HSS)inikeza ukumelana okuhle kokugqoka futhi kubiza kancane kune-cobalt noma i-carbide end Mills.I-HSS isetshenziselwa ukugaya inhloso evamile yakho kokubili okokusebenza okuyinsimbi nokungeyona insimbi.
I-Vanadium High Speed Steel (HSSE)yenziwe ngesivinini esikhulu sensimbi, ikhabhoni, i-vanadium carbide namanye ama-alloys aklanyelwe ukukhulisa ukumelana nokugqokwa kwe-abrasive kanye nokuqina.Ivamise ukusetshenziselwa ukusetshenziswa okujwayelekile ezinsimbini ezingagqwali nama-silicon aluminium aphezulu.
I-Cobalt (M-42: 8% Cobalt):Inikeza ukumelana nokugqokwa okungcono, ubulukhuni bokushisa obuphakeme kanye nokuqina kunensimbi yesivinini esikhulu (HSS).Kuncane kakhulu ukucutshungulwa noma ukucwiliswa okuncane ngaphansi kwezimo ezinzima zokusika, okuvumela ithuluzi ukuthi lisebenze ngokushesha ngo-10% kune-HSS, okuholela kumazinga amahle kakhulu okususwa kwensimbi kanye nokuqedwa okuhle.Kuyimpahla engabizi kakhulu elungele ukwenziwa kwensimbi eyinsimbi, insimbi ne-titanium alloys.
I-Powdered Metal (PM)iqinile futhi ibiza kakhulu kune-carbide eqinile.Iqinile futhi ayijwayele ukuphuka.I-PM yenza kahle ezintweni ezisetshenziswayo <30RC futhi isetshenziswa ezintweni ezishaqisayo nezigcwele isitokwe esifana ne-roughing.
I-Carbide eqinileinikeza ukuqina okungcono kune-high-speed steel (HSS).Ikwazi ukumelana nokushisa ngokwedlulele futhi isetshenziselwa izinhlelo zokusebenza zejubane eliphezulu 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.Kodwa-ke, amanani okuphakelayo asindayo afaneleka kakhulu kumathuluzi we-HSS kanye ne-cobalt.
Carbide-Amathiphuziboshwe onqenqemeni lwemizimba yamathuluzi ensimbi.Zisika ngokushesha kunensimbi enesivinini esikhulu futhi zivame ukusetshenziswa ezintweni ezisansimbi nezingenayo insimbi okuhlanganisa insimbi ekhonjiwe, insimbi kanye nama-alloys ensimbi.Amathuluzi anetiphu ye-Carbide ayinketho engabizi kakhulu yamathuluzi amakhulu obubanzi.
I-Polycrystalline Diamond (PCD)iyidayimane lokwenziwa elingashaqisi futhi elingagugi elivumela ukusika ngesivinini esikhulu ezintweni ezinganansimbi, amapulasitiki, nama-alloys omshini onzima kakhulu.
Ama-Standard Coatings/Finishes:
I-Titanium Nitride (TiN)iwukunamathela okuyinhloso evamile okunikeza ukuthambisa okuphezulu futhi okwandisa ukugeleza kwe-chip ezintweni ezithambile.Ukumelana nokushisa nobulukhuni kuvumela ithuluzi ukuthi lisebenze ngesivinini esiphezulu esingu-25% kuya ku-30% ngesivinini somshini ngokumelene namathuluzi angamboziwe.
I-Titanium Carbonitride (TiCN)iqinile futhi imelana kakhulu ne-Titanium Nitride (TiN).Ivame ukusetshenziswa ensimbi engagqwali, insimbi eyinsimbi kanye ne-aluminium alloys.I-TiCN inganikeza amandla okusebenzisa izinhlelo zokusebenza ngesivinini esiphezulu sokuphotha.Qaphela ezintweni ezingenayo i-ferrous ngenxa yokuthambekela kwenyongo.Idinga ukukhuphuka okungu-75-100% kuzivinini zomshini uma kuqhathaniswa namathuluzi angamboziwe.
I-Titanium Aluminium Nitride (TiAlN)inobulukhuni obuphezulu kanye nezinga lokushisa kwe-oxidation ngokumelene ne-Titanium Nitride (TiN) ne-Titanium Carbonitride (TiCN).Ilungele insimbi engagqwali, ama-alloy carbon steels aphezulu, ama-alloys asekelwe ku-nickel okushisa okuphezulu nama-titanium alloys.Sebenzisa ukuqapha ezintweni ezingenayo insimbi ngenxa yokuthambekela kwenyongo.Idinga ukukhuphuka okungu-75% kuya ku-100% kuzivinini zomshini uma kuqhathaniswa namathuluzi angamboziwe.
I-Aluminium Titanium Nitride (AlTiN)ingenye yezingubo ezimelana nokuqhunyiswa futhi ezinzima kakhulu.Ivamise ukusetshenziselwa ukwenza imishini yezindiza kanye nezinto zokwakha zasemkhathini, ingxubevange ye-nickel, insimbi engagqwali, i-titanium, i-cast iron ne-carbon steel.
I-Zirconium Nitride (ZrN)ifana ne-Titanium Nitride (TiN), kodwa inezinga lokushisa eliphakeme le-oxidation futhi imelana nokunamathela futhi ivimbela ukwakheka komphetho.Ivame ukusetshenziswa ezintweni ezingenayo insimbi ezihlanganisa i-aluminium, ithusi, ithusi ne-titanium.
Amathuluzi angagqokileungafaki ukwelashwa okusekelayo onqenqemeni lokusika.Asetshenziswa ngesivinini esincishisiwe sezinhlelo zokusebenza ezijwayelekile ezinsimbi ezingenayo insimbi.
