Hauv lub ntiaj teb uas muaj kev siv tshuab ua haujlwm ntau, kev xaiv ntawm M35 thiab M42 cobalt high-speed steel (HSS) ncaj shank twist drills yog ntau dua li kev txiav txim siab txog kev siv tshuab - nws yog kev nqis peev zoo hauv kev tsim khoom. Raws li lub hauv paus ntawm kev ua haujlwm ua qhov thoob plaws hauv kev lag luam, cov drills no sib xyaw ua ke kev tsim kho kom zoo nrog cov metallurgy siab heev los daws cov ntaub ntawv los ntawm cov yas mos mus rau superalloys. Tsab xov xwm no txiav txim siab qhov sib txawv ntawm M35 thiab M42 cobalt drills, txhawb nqa cov tuam txhab tsim khoom kom ua tiav lawv cov tswv yim cuab yeej.
Lub cev ntawm Kev Zoo Tshaj Plaws:HSS Ncaj Qha Nkaus Twist Drills
Lub tshuab laum ncaj uas muaj qhov sib txawv ntawm qhov sib txawv yog nws qhov yooj yim thiab hloov tau yooj yim. Nws muaj lub cylindrical shank (h6 kam rau siab) rau kev clamping ruaj ntseg hauv CNC collets, laum chucks, thiab milling tshuab, cov cuab yeej no tswj hwm txoj kab uas hla ntawm 0.25mm micro-drills mus rau 80mm cov khoom siv tho qhov hnyav. Lub qhov tsim ob-kauv, nrog rau lub kaum sab xis helix txij li 25 ° txog 35 °, ua kom muaj kev tshem tawm cov chips zoo, thaum 118 ° -135 ° lub kaum sab xis sib npaug lub zog nkag thiab ntug ruaj khov.
Cobalt's Crucible: M35 vs M42 Metallurgical Showdown
Qhov kev sib ntaus sib tua ntawm M35 (HSSE) thiab M42 (HSS-Co8) cobalt drills nyob ntawm lawv cov tshuaj lom neeg thiab thermal resilience:
M35 (5% Cobalt): Ib qho hlau sib npaug uas muaj zog dua M42 8–10%, zoo tagnrho rau kev txiav thiab kev teeb tsa uas yooj yim co. Kho cua sov rau HRC 64–66, nws tiv taus qhov kub txog li 600°C.
M42 (8% Cobalt): Qhov siab tshaj plaws ntawm qhov tawv liab, khaws cia HRC 65+ ntawm 650°C. Nrog ntxiv vanadium rau kev tiv thaiv kev hnav, nws zoo heev hauv kev tho qhov ceev ceev tas mus li tab sis yuav tsum tau ua tib zoo tuav kom tiv thaiv kev tawg.
Cov kev sim txhuam los ntawm cov neeg thib peb qhia tau tias M42 lub cuab yeej siv tau ntev dua 30% hauv 304 stainless hlau ntawm 30 m/min, thaum M35 ua tau zoo dua 15% hauv kev tiv thaiv kev cuam tshuam thaum lub sijhawm drilling peck.

Zoo Tshaj Plaws Rau:
Kev khawb tsis tu ncua hauv cov hlau cam khwb cia thiab cov hlau uas muaj carbon tsawg
Cov ntaub ntawv sib xyaw (CFRP, GFRP) uas xav tau kev co damping
Cov khw muag khoom ua haujlwm nrog cov txheej txheem ua haujlwm sib xyaw
Kev Lag Luam Zoo: 20% qis dua tus nqi ib lub qhov piv rau M42 hauv cov ntawv thov uas tsis yog abrasive
M42 Cobalt Drills: Tus yeej kub siab
Dominates Hauv:
Aerospace titanium (Ti-6Al-4V) thiab Inconel drilling ntawm 40+ m/min
Kev khawb qhov tob (8xD+) nrog cov kua txias los ntawm cov cuab yeej
Kev tsim cov hlau tawv ntau (HRC 45–50)
Qhov Zoo ntawm Kev Ceev: 25% ceev dua cov nqi pub rau hauv cov hlau tsis xeb piv rau M35
Kev Yeej Tshwj Xeeb Hauv Kev Lag Luam
Tsheb: M35 lub tshuab laum cav (txhuas A380) nrog 50,000-qhov lub neej ntev; M42 kov yeej lub nres rotor cam khwb cia hlau ntawm 1,200 RPM qhuav.
Aerospace: M42's TiAlN-coated variants txiav lub sijhawm drilling hauv nickel alloys los ntawm 40% piv rau cov cuab yeej carbide.
Khoom Siv Hluav Taws Xob: M35 lub 0.3 hli micro-drillings tho qhov tooj liab-clad laminates yam tsis muaj burring.
Kev Txawj Ntse Ua Haujlwm: Ua Kom Muaj Peev Xwm Tshaj Plaws ntawm Kev Tshawb Fawb
Txoj Kev Siv Dej Txias:
