Cov koob:Vim Li Cas Cov Khoom Siv Drill Bits Thiaj Tsis Ua Haujlwm | Tshooj 3
Cov Lus Tseem Ceeb:Qhov zoo ntawm cov laum HSS, qhov hnyav ntawm cov laum, qhov nyuaj ntawm cov laum, qhov ceev ntawm HSS, kev tshuaj xyuas qhov zoo ntawm cov laum, yuav ua li cas los soj ntsuam cov laum
Thaum cov neeg yuav khoom tshiab soj ntsuam cov qauv ntawm cov khoom siv laum, qee tus yuav ntsuas qhov hnyav ntawm cov laum. Qhov hnyav dua, qhov hlau zoo dua - lossis yog li ntawd, qhov kev xav mus.
Nws yog ib qho kev xav uas nkag siab tau. Qhov hnyav zoo li ib yam khoom siv. Tab sis thaum nws los txog rau cov khoom siv HSS, qhov hnyav yog ib qho ntawm cov cim qhia tsis zoo tshaj plaws. Qee zaum, cov khoom siv hnyav dua yog qhov cim ntawm cov khoom qis dua.
Nov yog vim li cas.
HSS Qhov Ceev Tsis Hloov Pauv Ntau Ntawm Cov Qib
Cov Hlau Ceev yog ib tsev neeg tshwj xeeb ntawm cov hlau siv ua cuab yeej uas txhais los ntawm nws cov ntsiab lus sib xyaw - tungsten, molybdenum, chromium, vanadium, thiab hauv qib cobalt, cobalt. Cov ntsiab lus no raug ntxiv rau hauv feem pua me me los tswj qhov nyuaj, kev tiv thaiv kev hnav, thiab qhov nyuaj liab.
Qhov ceev ntawm HSS thoob plaws cov qib sib xws - M2, M35, M42 - poob rau hauv qhov ntau thiab tsawg, kwv yees li 8.1 txog 8.3 g / cm³. M2 thiab M35 sib txawv hauv cov ntsiab lus cobalt (0% vs. kwv yees li 5%), tab sis cobalt qhov ceev (kwv yees li 8.9 g / cm³) yog ze txaus rau lub hauv paus hlau matrix uas sib xyaw 5% ntawm nws rau hauv cov hlau alloy hloov qhov ceev tag nrho los ntawm tsawg dua 0.1 g / cm³. Qhov sib txawv ntawd tsis pom los ntawm tes thiab tsis tseem ceeb txawm tias ntawm qhov ntsuas qhov tseeb.
Hauv cov ntsiab lus siv tau: koj siv tsis tau qhov hnyav los sib txawv M2 ntawm M35, lossis tus qauv HSS los ntawm cobalt-qib HSS.
Yog li ntawd Vim li cas qee cov laum ntsis thiaj li hnyav dua?
Yog tias ob lub qhov tho qhov uas muaj tib qhov loj me zoo li txawv ntawm qhov hnyav, qhov kev piav qhia yuav luag ib txwm yog geometry - tsis yog cov khoom siv.
Qhov hnyav ntawm lub ntsis laum yog txiav txim siab los ntawm ntau npaum li cas cov khoom siv uas nws muaj. Rau qhov ntev thiab txoj kab uas hla, qhov hloov pauv tseem ceeb yog pes tsawg hlau tau raug tshem tawm thaum lub sijhawm sib tsoo. Lub geometry ntawm lub flute - qhov tob thiab dav ntawm cov channel helical txiav rau hauv lub cev - ncaj qha tswj qhov no. Cov flutes tob dua, dav dua tshem tawm ntau cov khoom siv. Cov flutes qis dua tawm ntau dua.
Ib lub chaw tsim khoom tuaj yeem tsim cov laum hnyav dua los ntawm kev sib tsoo cov flutes uas tsis tob. Lub ntsis khaws cov khoom siv tseem ceeb ntau dua, yog li nws hnyav dua. Tab sis cov flutes uas tsis tob muaj qhov tshwm sim: kev tshem tawm cov chips ua haujlwm tsawg dua, kev sib txhuam txiav nce ntxiv, thiab cua sov nce sai dua ntawm thaj chaw txiav. Hauv cov ntaub ntawv nyuaj lossis ntawm cov khoom pub ntau dua, qhov no ua rau hnav sai dua thiab muaj kev pheej hmoo ntau dua ntawm kev ua tsis tiav ua ntej lub sijhawm.
Qhov no txhais tau tias lub laum hnyav dua tsis yog lub laum zoo dua. Tej zaum nws tsuas yog ib qho uas muaj ib lub ces kaum txiav hauv geometry - thiab tus neeg yuav khoom yuam kev qhov tsos mob rau lub cim qhia txog qhov zoo.
Qhov Hnyav Qhia Tau Li Cas Tiag
Qhov hnyav qhia txog qhov ntim ntawm cov hlau uas tseem tshuav. Qhov ntim yog tswj los ntawm kev sib tsoo. Qhov zoo ntawm kev sib tsoo yog qhov kev txiav txim siab tsim khoom.
Ib lub chaw tsim khoom uas muaj kev paub dhau los yuav zom cov flutes raws li qhov geometry uas tau teev tseg los ntawm daim ntawv thov - DIN 338 lossis cov qauv sib npaug txhais lub kaum sab xis ntawm helix, qhov tob ntawm lub flute, thiab qhov geometry ntawm cov ntsiab lus rau ib qho laj thawj. Cov qhov ntev no tau raug kho kom zoo dua thoob plaws ntau xyoo ntawm kev siv hauv kev lag luam los sib npaug ntawm kev tshem tawm cov chip, lub zog ntawm cov ntug txiav, thiab kev ua haujlwm ntawm kev khawb.
Ib lub laum uas txawv ntawm tus qauv geometry mus rau qhov hnyav dua tsis tau txhim kho qhov sib npaug ntawd. Nws tau ua rau nws puas tsuaj.
Cov Metrics Uas Tseem Ceeb Tiag
Yog tias qhov hnyav tsis yog qhov qhia tau tseeb, cov neeg yuav khoom yuav tsum saib dab tsi thaum soj ntsuam qhov zoo ntawm lub laum?
Cov hloov pauv tseem ceeb yog:
•Qhov nyuaj.Tom qab kho cua sov, qhov ntug txiav ntawm lub laum M2 HSS uas tsim tau zoo yuav tsum ncav cuag kwv yees li HRC 63–65. M35 cobalt yuav tsum ncav cuag HRC 64–66. Cov nqi hardness sab nraum cov ntau yam no qhia txog teeb meem nrog kev kho cua sov - tsis yog qhov kub dhau, tsis txaus quench rate, lossis tsis tswj hwm tempering. Hardness tuaj yeem ntsuas ncaj qha nrog Rockwell hardness tester.
•Cov khoom siv sib xyaw.Kev tshuaj xyuas Spectrometer (OES - Optical Emission Spectrometry) yog tib txoj kev ntseeg tau los xyuas seb lub laum puas muaj cov khoom sib xyaw uas tau thov. Cov ntsiab lus Cobalt, feem pua ntawm tungsten, vanadium - tsis muaj ib qho ntawm cov no pom lossis hnyav tau. Lawv xav tau kev kuaj xyuas hauv chaw kuaj mob.
•Qhov tseeb ntawm geometry.Lub kaum sab xis, lub kaum sab xis helix, lub suab flute symmetry, thiab lub xwm txheej ntawm ntug chisel txhua yam cuam tshuam rau kev ua haujlwm ntawm kev txiav. Cov no ntsuas tau nrog cov cuab yeej ntsuas optical lossis cov projectors profile.
•Kev sib xws ntawm pawg.Ib qho qauv uas dhau los tsis txaus. Cov neeg yuav khoom lag luam xav tau kev ua tau zoo uas tuav tau thoob plaws hauv ib pawg ntau lawm. Kev sib xws ntawm qhov nyuaj, geometry, thiab qhov tiav ntawm qhov chaw thoob plaws ntau pua lossis ntau txhiab daim yog ib lo lus nug txog cov txheej txheem tsim khoom, tsis yog ib lo lus nug txog kev tshuaj xyuas ib chav.
•Qhov chaw tiav.Kev sib tsoo zoo pom tseeb. Cov cim sib tsoo tsis zoo, cov nplaim tsis sib luag, lossis cov cim sib tsoo pom tseeb ntawm ntug txiav yog cov cim qhia txog teeb meem ntawm cov txheej txheem. Lub laum me me uas tau sib tsoo zoo qhia tau tias cov nplaim du thiab huv si nrog cov qauv ntug sib xws.
Qhov no txhais li cas rau kev txiav txim siab txog kev nrhiav khoom
Thaum tus neeg muag khoom xa cov qauv, tsis txhob xav txog qhov hnyav ntawm lawv. Qhov kev kuaj xyuas tseem ceeb yog thov daim ntawv pov thawj khoom siv, tshuaj xyuas geometry hauv qab magnification yog tias ua tau, thiab - rau cov xaj loj - thov cov ntaub ntawv xeem hardness lossis kev txheeb xyuas cov khoom siv ywj pheej.
Qhov hnyav tsis yog ib txoj kev luv luv. Nws yog suab nrov.
Qhov zoo ntawm lub laum HSS nyob ntawm nws cov hlau sib xyaw, nws txoj kev kho cua sov, thiab nws cov qauv av. Tsis muaj ib qho ntawm cov no pom ntawm qhov ntsuas.
Txog Cov Yeeb Yam No
Vim Li Cas Cov Khoom Siv Drill Bits Tsis Ua Haujlwm yog cov koob txheej txheem los ntawm peb pab neeg tsim khoom. Txhua tsab xov xwm tsom mus rau ib qho tseem ceeb hauv kev ua haujlwm ntawm cov khoom siv drill bit - los ntawm cov khoom siv raw mus rau kev ntim khoom. Lub hom phiaj yog yooj yim: pab cov neeg yuav khoom nkag siab txog yam lawv tab tom yuav, thiab cov lus nug twg tsim nyog nug.
