Uma abathengi besibuza ngama-drill bits e-HSS, omunye wemibuzo evame kakhulu uthi: "Uyini umehluko phakathi kwe-M42, i-M35, i-M2 — futhi kuthiwani nge-4341?
Umbuzo ulungile. Zonke ziyizinto zensimbi ezisheshayo (i-HSS), futhi ebusweni, zibukeka zifana kakhulu. Kodwa izinga olikhethayo linomthelela omkhulu ekutheni i-drill yakho ihlala isikhathi esingakanani, ukuthi isebenza kanjani ngaphansi kokushisa, nokuthi ifanele yini into oyisikayo.
Nansi incazelo ecacile.
Iyini i-HSS, futhi kungani ibanga libalulekile?
I-HSS imele i-High-Speed Steel — i-alloy yensimbi yamathuluzi eyenzelwe ukusika insimbi ngesivinini esiphezulu ngaphandle kokulahlekelwa ubulukhuni bayo. Ngokungafani nensimbi yekhabhoni, i-HSS igcina umkhawulo wayo wokusika ngisho noma ishisa ngesikhathi sokubhoboza.
Kodwa akuzona zonke i-HSS ezifanayo. Ibanga — i-M42, i-M35, i-M2, i-4341, nabanye — libhekisela ekwakhiweni kwe-alloy ethile. Umehluko omncane ezintweni ezifana ne-tungsten, i-molybdenum, i-vanadium, ne-cobalt uholela ekwehlukeni okukhulu ekusebenzeni.
Qaphela: I-M42 ithatha indlela ehlukile kune-M35 — isebenzisa okuqukethwe okuphezulu kakhulu kwe-molybdenum esikhundleni se-tungsten esindayo, okwenza ibe lukhuni kakhulu ngokushisa ngentengo ye-alloy encane.
I-HRC ephezulu isho ukumelana nokuguguleka okungcono — kodwa futhi nokuqhekeka kancane. I-M42 inzima kakhulu, kodwa idinga ukusethwa okuzinzile nokuqinile ukuze igweme ukuqhekeka. I-4341 ithambile kakhulu futhi iqine kakhulu, okwenza ikwazi ukubekezelela ukusetshenziswa okuvamile.
I-M42 — Izinga Lokusebenza Eliphezulu Lama-Alloys Anzima
I-M42 iphezulu kakhulu kuhlu lwe-HSS. Njengoba ine-cobalt engu-8% kanye nokuqukethwe okuphezulu kakhulu kwe-molybdenum (HS2-9-1-8, eyaziwa nangokuthi i-HSSCo8, SKH59, P2M9K8, noma i-S500), yenzelwe izinto ezingaguga ngokushesha i-HSS drill ejwayelekile.
Sikhuluma ngama-alloy e-nickel, i-titanium, izinsimbi eziqinile, ama-superalloy angashisi ukushisa — izinto ezisetshenziswa yizindiza, ezokuvikela, kanye nokukhiqiza okuthuthukile. I-M42 iphatha lokhu ngoba ingamelana namazinga okushisa angaphezu kuka-680°C ngenkathi igcina umkhawulo omuhle nobukhali.
Impikiswano ukuthi i-M42 ibuthakathaka kakhulu kunezinhlobo ezingaphansi kwayo. Isebenza kahle kakhulu ekusethweni okuqinile, okulawulwayo lapho ukudlidliza kuncishiswa khona. Iphinde ibe nezindleko eziphakeme — kodwa ukuze kusetshenziswe kahle, isikhathi eside sokusebenza kwamathuluzi siyakuvumela lokho.
M35 — Uma Ubhoboza Izinto Eziqinile
I-M35 inezela i-cobalt engu-5% esisekelweni se-M2 (yingakho igama elihlukile libizwa ngokuthi i-HSSCo5 noma i-HS6-5-2-5). Lokho okuqukethwe yi-cobalt kuphakamisa ukumelana nokushisa kwe-drill ngokuphawulekayo — kuze kufike cishe ku-630–650°C — futhi kusunduza ubulukhuni ku-63–66 HRC.
Kwabasabalalisi abahlinzeka ngezimboni ezifana nezimoto, i-HVAC, noma ukwenziwa okulula — lapho umsebenzi wensimbi engagqwali uvame khona — i-M35 iwukuthuthukiswa okuhlakaniphile kune-M2. Inzima, ayigugi kakhulu, futhi inikeza impilo yamathuluzi ende ezimweni ezinzima ngaphandle kokukhathazeka kobuthakathaka be-M42.
Cabanga nge-M35 njengendawo enhle: ingcono kakhulu kune-HSS ejwayelekile, kodwa isasebenza futhi ithembekile ezindaweni eziningi zokusebenzela.
I-M2 — Indinganiso Esebenzela Imisebenzi Eminingi
I-M2 iyibanga le-HSS elisetshenziswa kakhulu emhlabeni. Igama layo eliphelele yi-HS6-5-2 (eyaziwa nangokuthi i-SKH51 noma i-P6M5), okubonisa ukwakheka kwayo: i-tungsten engu-6%, i-molybdenum engu-5%, i-vanadium engu-2% — ayikho i-cobalt.
Yinto esetshenziswa kakhulu ekubholeni ngezinhloso ezijwayelekile kuzo zonke izinhlobo zezinsimbi — insimbi ethambile, i-aluminium, ithusi, insimbi ephonswe, nokuningi. Ama-drill e-M2 agcwele umhlabathi, ahlala njalo, futhi ayabiza kahle. Ezindaweni eziningi zokusebenzela ezijwayelekile kanye nezindawo zokukhiqiza, i-M2 yilokho kanye okudingayo.
Uma umthengi engashongo ibanga, i-M2 cishe njalo yilokho akutholayo — futhi ezinhlelweni eziningi, lokho kulungile impela.
4341 — Inketho Yokungena Esezingeni Eliqinile Neliguquguqukayo
I-4341 (ebhalwe futhi ngokuthi i-W4Mo3Cr4VSi) iyi-tungsten-molybdenum HSS grade ephansi kwe-M2 ngokusebenza, kodwa inikeza ukuqina okuhle kakhulu kanye nokumelana nomthelela. Ithandwa kakhulu ezimakethe lapho ukusebenza kahle kwezindleko kuyinto eza kuqala.
Uma kuqhathaniswa ne-M2, i-4341 inobulukhuni obuphansi kanye nobunzima obushisayo obuncishisiwe — okusho ukuthi ngeke ikwazi ukumelana kahle emazingeni okushisa aphezulu. Kodwa ekubholeni izinsimbi ezithambile noma ezisetshenziswayo lapho ukubhoboza kuvame ukushintshwa khona kunokunakekelwa, yenza umsebenzi wenziwe ngendlela ethembekile nengabizi.
I-4341 iyindlela evamile yokukhetha ama-bit drill apakishiwe athengiswa ngeziteshi zokuthengisa nezehadiwe, lapho intengo ibaluleke kakhulu kunokusebenza okuphezulu. Akuyona ithuluzi elihle kakhulu lama-alloy aqinile — kodwa emsebenzini olula wansuku zonke, ithola indawo yayo.
