Xa abathengi besibuza ngee-HSS drill bits, omnye wemibuzo eqhelekileyo ngulo: "Yintoni umahluko phakathi kwe-M42, i-M35, i-M2 — kwaye kuthekani nge-4341?
Ngumbuzo ofanelekileyo. Zonke zizinto zentsimbi ekhawulezayo (HSS), kwaye phezu kwayo, zifana kakhulu. Kodwa uhlobo olukhethayo lunefuthe lokwenyani ekubeni i-drill yakho ihlala ixesha elingakanani, isebenza njani xa ishushu, kwaye ingaba ifanelekile na kwizinto ozisikayo.
Nantsi indlela ecacileyo yokuchaza.
Yintoni i-HSS, kwaye kutheni iBanga libalulekile?
I-HSS imele i-High-Speed Steel — i-alloy yentsimbi yesixhobo eyenzelwe ukusika isinyithi ngesantya esiphezulu ngaphandle kokulahlekelwa bubunzima bayo. Ngokungafaniyo nentsimbi yekhabhoni, i-HSS igcina umda wayo ophambili nokuba ishushu ngexesha lokugrumba.
Kodwa ayizizo zonke ii-HSS ezifanayo. Udidi — M42, M35, M2, 4341, kunye nezinye — lubhekisa kulwakhiwo oluthile lwe-alloy. Umahluko omncinci kwizinto ezifana ne-tungsten, i-molybdenum, i-vanadium, kunye ne-cobalt ukhokelela kumahluko amakhulu ekusebenzeni.
Qaphela: I-M42 isebenzisa indlela eyahlukileyo kune-M35 — isebenzisa umxholo ophezulu kakhulu we-molybdenum endaweni ye-tungsten enzima, nto leyo eyinika ubulukhuni obushushu obuphezulu ngexabiso eliphantsi le-alloy.
I-HRC ephezulu ithetha ukuba iyakwazi ukumelana nokuguguleka okungcono — kodwa ikwanokubuthathaka kancinci. I-M42 yeyona inzima, kodwa ifuna ukuseta okuzinzileyo nokuqinileyo ukuze iphephe ukuqhekeka. I-4341 yeyona ithambileyo neyomeleleyo, nto leyo eyenza ukuba ikwazi ukuxolela xa isetyenziswa ngokubanzi.
I-M42 — Umgangatho oPhezulu wokusebenza kwee-alloys ezinzima
I-M42 iphezulu kuluhlu lwe-HSS. Ine-cobalt eyi-8% kunye nomxholo ophezulu kakhulu we-molybdenum (HS2-9-1-8, ekwaziwa ngokuba yi-HSSCo8, SKH59, P2M9K8, okanye i-S500), yenzelwe izixhobo eziya kukhawuleza ziguge i-HSS drill eqhelekileyo.
Sithetha ngee-alloys ze-nickel, i-titanium, iintsimbi eziqinileyo, ii-superalloys ezingatshisi ubushushu — izinto ezixhomekeke kuzo i-aerospace, ukhuselo, kunye nemveliso ephucukileyo. I-M42 iyazisingatha ezi kuba inokumelana namaqondo obushushu angaphaya kwama-680°C ngelixa igcina umphetho obukhali nocolekileyo.
Ingxaki kukuba i-M42 ibuthathaka ngakumbi kunee-grades ezingaphantsi kwayo. Isebenza kakuhle kwiindawo eziqinileyo nezilawulwayo apho ukungcangcazela kuncitshiswa khona. Ikwabiza kakhulu — kodwa xa isetyenziswa ngokufanelekileyo, ixesha elide lesixhobo liyayithethelela loo nto.
M35 — Xa Ugrumba Izinto Eziqinileyo
I-M35 yongeza i-5% ye-cobalt kwisiseko se-M2 (yiyo loo nto igama layo litshintshiweyo yi-HSSCo5 okanye i-HS6-5-2-5). Loo mxholo we-cobalt uphakamisa ukumelana nobushushu kwe-drill ngokubonakalayo - ukuya kuthi ga kwi-630–650°C - kwaye utyhala ubunzima ukuya kwi-63–66 HRC.
Kwabasasazi ababonelela ngeenkonzo kumashishini afana neemoto, i-HVAC, okanye ukwenziwa kwezinto ezilula — apho umsebenzi wentsimbi engagqwaliyo uxhaphakileyo — i-M35 yindlela yokuphucula ekrelekrele kune-M2. Inzima, ayigugi, kwaye inika ubomi obude bezixhobo kwiimeko ezinzima ngaphandle kwenkxalabo yokuba buthathaka njenge-M42.
Cinga nge-M35 njengendawo entle: ingcono kakhulu kune-HSS eqhelekileyo, kodwa isasebenza kwaye ithembekile kwiindawo ezahlukeneyo zokusebenzela.
I-M2 — Umgangatho Osebenza Kwimisebenzi Emininzi
I-M2 yeyona nqanaba le-HSS esetyenziswa kakhulu kwihlabathi liphela. Igama layo elipheleleyo yi-HS6-5-2 (ekwaziwa ngokuba yi-SKH51 okanye i-P6M5), ebonisa ukwakheka kwayo: i-6% ye-tungsten, i-5% ye-molybdenum, i-2% ye-vanadium — akukho cobalt.
Yinto efanelekileyo yokugrumba ngokubanzi kwiintlobo ngeentlobo zeentsimbi — intsimbi ethambileyo, i-aluminium, ubhedu, isinyithi esityhidiweyo, nokunye. Ii-M2 drills zigayiwe ngokupheleleyo, zihlala zifana, kwaye zingabizi kakhulu. Kwiimeko ezininzi zeworkshop kunye nemveliso, i-M2 yeyona nto uyifunayo.
Ukuba umthengi akachazi ibakala, i-M2 phantse isoloko iyinto ayifumanayo — kwaye kwiizicelo ezininzi, oko kulungile ngokugqibeleleyo.
4341 — Ukhetho Olunzima NoluneMilinganiselo Ehlukeneyo Lokungena Kwinqanaba
I-4341 (ekwabhalwe njenge-W4Mo3Cr4VSi) yi-tungsten-molybdenum HSS grade esezantsi kancinci kune-M2 ngokusebenza, kodwa inika ukuqina okugqwesileyo kunye nokumelana nempembelelo. Ithandwa kakhulu kwiimarike apho ukusebenza kakuhle kweendleko kuyeyona nto iphambili.
Xa kuthelekiswa ne-M2, i-4341 inobunzima obuphantsi kunye nobunzima obuphantsi bobushushu — oko kuthetha ukuba ayizukukwazi ukumelana kakuhle kubushushu obuphezulu. Kodwa ekubholeni iintsimbi ezithambileyo okanye kwiindawo apho ukubhola kutshintshwa rhoqo endaweni yokugcinwa, yenza umsebenzi ube ngothembekileyo nangendlela engabiziyo.
I-4341 lukhetho oluqhelekileyo kwiiseti zeebhithi zokubhola ezipakishiweyo ezithengiswa ngokuthengisa kunye neendlela zehardware, apho ixabiso libaluleke ngaphezu kokusebenza okuphezulu. Ayisosixhobo silungileyo see-alloys ezinzima — kodwa kwimisebenzi yemihla ngemihla elula, ifumana indawo yayo.
