Cov ntaub ntawv ntawm Tungsten Carbide End Mills thiab Nws Qhov Ua Tau Tsis Ua Haujlwm

Puas yog qhov kawg mills ua los ntawm carbide?

Feem ntau cov mills kawg yog tsim los ntawm cov cobalt hlau alloys - hu ua HSS (High Speed ​​Steel), los yog los ntawm tungsten carbide. Kev xaiv ntawm cov khoom ntawm koj xaiv kawg zeb yuav nyob ntawm qhov hardness ntawm koj workpiece thiab lub siab tshaj plaws spindle ceev ntawm koj lub tshuab.

Dab tsi yog qhov toughest kawg zeb?

Carbide kawg mills.

Carbide kawg mills yog ib qho ntawm cov cuab yeej txiav nyuaj tshaj plaws. Tom ntej no rau pob zeb diamond muaj tsawg heev lwm cov ntaub ntawv nyuaj dua carbide. Qhov no ua rau carbide muaj peev xwm ntawm machining yuav luag txhua yam hlau yog tias ua tiav. Tungsten Carbide ntog ntawm 8.5 thiab 9.0 ntawm Moh lub hardness nplai, ua rau nws yuav luag nyuaj li pob zeb diamond.

Dab tsi yog qhov zoo tshaj plaws kawg zeb khoom rau steel?

Feem ntau, carbide kawg mills ua haujlwm zoo tshaj plaws rau cov hlau thiab nws cov alloys vim nws muaj thermal conductivity ntau dua thiab ua haujlwm zoo rau cov hlau tawv. Carbide kuj tseem ua haujlwm ntawm qhov nrawm dua, uas txhais tau tias koj lub tshuab txiav tuaj yeem tiv taus qhov kub thiab txias thiab tuaj yeem tiv thaiv kev hnav thiab tsim kua muag. Thaum ua tiav cov hlau tsis muaj steel, yuav tsum muaj lub suab nrov nrov thiab / lossis siab helix rau qhov zoo tshaj plaws. Qhov kawg mills rau stainless hlau yuav muaj lub kaum sab xis helix tshaj 40 degrees, thiab flute suav ntawm 5 lossis ntau dua. Rau ntau qhov kev ua tiav cov cuab yeej ua tiav, lub tshuab raj suav tuaj yeem muaj li ntawm 7 flutes mus rau siab li 14.

Qhov twg zoo dua, HSS lossis carbide kawg mills?

Khoom Carbide muab rigidity zoo dua li high-speed steel (HSS). Nws yog tsis tshua muaj kub resistant thiab siv rau kev kub ceev daim ntaub ntawv ntawm cam khwb cia hlau, nonferrous cov ntaub ntawv, yas thiab lwm yam tawv-rau-tshuab ntaub ntawv. Carbide kawg mills muab rigidity zoo dua thiab tuaj yeem khiav 2-3X sai dua HSS.

Vim li cas cov mills ua tsis tiav?

1. Khiav nws nrawm dhau lossis qeeb dhauYuav cuam tshuam Tool Lub Neej.

Kev khiav ib lub cuab yeej ceev heev tuaj yeem ua rau qhov zoo tshaj plaws nti loj lossis txawm tias cov cuab yeej puas tsuaj tsis ua haujlwm. Hloov pauv, RPM qis tuaj yeem ua rau deflection, ua tiav tsis zoo, lossis tsuas yog txo qis cov hlau tshem tawm.

2. Pub me me los yog ntau dhau.

Lwm qhov tseem ceeb ntawm kev nrawm thiab txau, qhov zoo tshaj plaws pub tus nqi rau txoj haujlwm sib txawv ntawm cov cuab yeej thiab cov khoom siv ua haujlwm. Yog tias koj khiav koj lub cuab yeej nrog qeeb qeeb ntawm tus nqi pub, koj khiav txoj kev pheej hmoo ntawm kev txiav cov chips thiab ua kom cov cuab yeej nrawm dua. Yog tias koj khiav koj lub cuab yeej nrog ceev ceev ntawm tus nqi pub, koj tuaj yeem ua rau lub cuab yeej tawg. Qhov no yog qhov tseeb tshwj xeeb nrog cov cuab yeej me me.

3. Siv cov tsoos Roughing.

Thaum cov tsoos roughing yog qee zaus tsim nyog lossis pom zoo, nws feem ntau qis dua rau High Efficiency Milling (HEM). HEM yog cov txheej txheem roughing uas siv qis Radial Depth of Cut (RDOC) thiab siab dua Axial Depth of Cut (ADOC). Qhov no kis tau tusyees nyob rau hauv lub txiav ntug, dissipates tshav kub, thiab txo lub sij hawm ntawm lub cuab tam tsis ua hauj lwm. Dhau li ntawm cov cuab yeej ua tau zoo zuj zus ntxiv, HEM kuj tseem tuaj yeem tsim qhov ua tiav zoo dua thiab siab dua cov hlau tshem tawm, ua rau nws muaj txiaj ntsig zoo rau koj lub khw.

4. Siv cov cuab yeej tuav tsis raug thiab nws cov txiaj ntsig rau lub neej cuab yeej.

Kev khiav haujlwm kom raug tsis tshua muaj kev cuam tshuam hauv cov cuab yeej tuav tau zoo. Kev sib txuas ntawm lub tshuab tsis zoo tuaj yeem ua rau cov cuab yeej khiav tawm, rub tawm, thiab cov khoom seem. Feem ntau hais lus, ntau cov ntsiab lus ntawm kev tiv tauj ib lub cuab yeej muaj nrog lub l's shank, qhov kev ruaj ntseg ntau dua. Hydraulic thiab shrink haum cov tuav tuav muaj kev ua tau zoo dua li cov txheej txheem nruj, raws li qee qhov kev hloov kho shank.

5. Tsis siv qhov sib txawv Helix/Pitch Geometry.

Ib qho tshwj xeeb ntawm ntau yam kev ua haujlwm siab kawg mills, sib txawv helix, lossis qhov sib txawv, geometry yog qhov hloov maj mam hloov mus rau tus qauv kawg zeb geometry. Qhov no geometrical feature ua kom ntseeg tau tias lub sijhawm ncua sij hawm ntawm kev sib cuag nrog cov khoom ua haujlwm sib txawv, tsis yog ib txhij nrog txhua qhov kev sib hloov.Qhov kev hloov pauv no txo ​​qis kev sib tham los ntawm kev txo qis kev sib haum xeeb, uas ua rau cov cuab yeej siv lub neej thiab ua tau zoo dua.

6. Xaiv cov txheej tsis raug tuaj yeem hnav ntawm lub neej cuab yeej.

Txawm hais tias nws kim heev, lub cuab yeej nrog cov txheej txheem zoo rau koj cov khoom siv ua haujlwm tuaj yeem ua rau txhua qhov sib txawv. Ntau cov coatings ua rau kom lubricity, ua rau cov cuab yeej ua haujlwm qeeb, thaum lwm tus ua rau muaj zog thiab ua kom puas. Txawm li cas los xij, tsis yog tag nrho cov coatings haum rau txhua yam ntaub ntawv, thiab qhov sib txawv yog qhov pom tseeb tshaj plaws hauv cov ntaub ntawv ferrous thiab non-ferrous. Piv txwv li, Aluminium Titanium Nitride (AlTiN) txheej ua rau muaj zog thiab kub tsis kam hauv cov ntaub ntawv ferrous, tab sis muaj kev sib raug zoo rau txhuas, ua rau cov khoom ua haujlwm adhesion rau cov cuab yeej txiav. Titanium Diboride (TiB2) txheej, ntawm qhov tod tes, muaj qhov tsis tshua muaj affinity rau txhuas, thiab tiv thaiv kev txiav ntug tsim thiab nti ntim, thiab txuas ntxiv lub neej ntawm cov cuab yeej.

7. Siv qhov ntev ntawm kev txiav.

Thaum lub sij hawm ntev ntawm kev txiav (LOC) yog qhov tsim nyog rau qee txoj haujlwm, tshwj xeeb tshaj yog nyob rau hauv kev ua tiav, nws txo qhov rigidity thiab lub zog ntawm cov cuab yeej txiav. Raws li txoj cai dav dav, lub cuab yeej LOC yuav tsum tsuas yog ntev npaum li qhov xav tau los xyuas kom meej tias cov cuab yeej khaws cia ntau npaum li qhov qub substrate li sai tau. Qhov ntev ntawm lub cuab yeej LOC qhov yooj yim dua rau deflection nws dhau los, ua rau nws txo qis nws lub neej zoo thiab ua rau muaj feem cuam tshuam.

8. Xaiv cov Flute suav tsis raug.

Raws li qhov yooj yim li nws zoo li, lub cuab yeej lub tshuab raj suav muaj qhov cuam tshuam ncaj qha thiab tseem ceeb ntawm nws qhov kev ua haujlwm thiab kev khiav haujlwm. Ib lub cuab yeej nrog lub tshuab raj qis (2 mus rau 3) muaj cov raj nplaim loj dua thiab cov tub ntxhais me me. Raws li nrog LOC, qhov tsawg dua substrate seem ntawm cov cuab yeej txiav, qhov tsis muaj zog thiab tsis tshua muaj zog. Ib lub cuab yeej nrog lub suab nrov nrov (5 lossis siab dua) ib txwm muaj cov tub ntxhais loj dua. Txawm li cas los xij, suav flute siab tsis yog ib txwm zoo dua. Kev suav cov flute qis feem ntau yog siv rau hauv cov khoom siv txhuas thiab cov khoom tsis-ferrous, ib feem vim tias qhov softness ntawm cov ntaub ntawv no tso cai rau ntau qhov yooj yim rau kev tshem tawm cov hlau ntau ntxiv, tab sis kuj vim yog cov khoom ntawm lawv cov chips. Cov ntaub ntawv uas tsis yog-ferrous feem ntau tsim ntev dua, stringier chips thiab qis dua flute suav pab txo cov nti recutting. Cov cuab yeej siv flute ntau dua feem ntau yog tsim nyog rau cov khoom siv ferrous nyuaj, ob qho tib si rau lawv lub zog muaj zog thiab vim tias chip recutting tsis tshua muaj kev txhawj xeeb vim cov ntaub ntawv no feem ntau tsim cov chips me me.

Yog tias koj txaus siab rau cov khoom siv tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem ua tauTiv tauj peblos ntawm xov tooj los yog xa ntawv ntawm sab laug, los yogXa ntawv rau pebnyob hauv qab ntawm nplooj ntawv no.
