Yuav ua li cas xaiv lub milling cutter thiab siv cov ntsiab lus
Txoj cai xaiv ntawm milling cutter:
Txhawm rau xaiv cov khoom siv hluav taws xob zoo thiab siv tau zoo, lub tshuab txiav milling uas tsim nyog tshaj plaws yuav tsum raug xaiv raws li cov duab ntawm cov khoom yuav raug txiav, machining raug, thiab lwm yam. Yog li ntawd, cov ntsiab lus tseem ceeb xws li txoj kab uas hla ntawm lub milling cutter, tus lej. ntawm cov npoo, qhov ntev ntawm ntug, lub kaum sab xis helix, thiab cov khoom siv yuav tsum tau txiav txim siab.
Khoom siv:
Thaum txiav cov hlau, cov hlau tsis muaj hlau, thiab cov khoom siv hlau cam ntawm cov qauv, cov hlau ceev ceev (sib npaug rau SKH59) cov milling cutters uas muaj 8% cobalt yuav tsum tau siv, uas tuaj yeem ua haujlwm zoo dua.
Rau kev ua haujlwm zoo dua thiab siv tau ntev dua, coated milling cutters, hmoov HSS milling cutters, thiab carbide milling cutters tuaj yeem xaiv.
Tus naj npawb ntawm flutes: ib qho tseem ceeb cuam tshuam rau kev ua haujlwm ntawm milling cutters.
Ob chav-edged riam: lub nti zawj yog qhov loj, yog li nws yooj yim rau kev tso tawm ntawm cov hlau chips, tab sis qhov chaw hla ntawm cov cuab yeej yog me me, uas txo cov rigidity, yog li nws feem ntau yog siv rau kev txiav cov zawj.
Quadruple txiav ntug: Lub hnab ntim khoom me me, lub peev xwm tawm ntawm cov hlau chips yog tsawg, tab sis qhov chaw hla ntawm lub cuab yeej nqaim, yog li qhov nce rigidity feem ntau yog siv rau sab txiav.
Hniav ntev:
Thaum machining, yog tias qhov ntev ntawm kev txiav ntug raug txo, kev pab cuam lub neej ntawm lub cuab yeej tuaj yeem txuas ntxiv.
Lub protruding ntev ntawm lub milling cutter ncaj qha cuam tshuam lub rigidity ntawm lub milling cutter, yog li kev saib xyuas yuav tsum tsis txhob ua nws ntev heev.
Helix kaum sab xis:
• Lub kaum sab xis me me (15 degrees): tsim nyog rau keyway milling cutters
• Lub kaum sab xis nruab nrab (30 degrees): dav siv
• Lub kaum sab xis loj (50 degrees): siab helix lub kaum sab xis cutters rau kev siv tshwj xeeb
Kev tu cov khoom siv thiab cov cuab yeej siv
Kev vibration yog txo qis thiab nws nruj txaus los ua ntawm nws lub peev xwm tag nrho nrog cov cuab yeej zoo.
