Yog tias koj ua tib zoo tshuaj xyuas cov khoom sib txawv, koj tuaj yeem pom tias cov grooves kauv -paub tiasflutes- tsis yog ib txwm zoo li qub. Qee cov cuab yeej laum muaj cov kab nrib pleb, thaum lwm tus zoo nkaus li flatter.
Qhov txawv no hu uahelix lub kaum sab xis, thiab nws ua lub luag haujlwm tseem ceeb hauv kev xyaum ua haujlwm li cas thaum txiav cov khoom sib txawv.
Kev nkag siab tias yog vim li cas cov cuab yeej laum siv cov kaum sab xis sib txawv tuaj yeem pab piav qhia seb cov cuab yeej drilling zoo li cas rau cov hlau, ntoo, lossis cov ntawv thov pob zeb.
Dab tsi yog Helix Angle hauv Drill Bit?
Covhelix lub kaum sab xisyog hais txog lub kaum sab xis uas tsim los ntawm cov kauv flute txheeb ze rau lub laum ntsis lub axis.
Hauv cov ntsiab lus yooj yim, nws txiav txim siab li cas aggressively lub kauv txav chips (khoom khib nyiab) tawm ntawm lub qhov thaum lub sij hawm drilling.
Hom helix lub kaum sab xis poob rau hauv peb qhov dav dav:
| Helix Angle | Kev siv yam |
|---|---|
| Tsawg helix (10℃-20 degree) | Cov ntaub ntawv nyuaj thiab cov khoom tawg yooj yim |
| Standard helix (25℃-30 degree) | General - lub hom phiaj drilling |
| Siab helix (35℃-45 degree) | Cov ntaub ntawv mos thiab sib sib zog nqus- qhov drilling |
Txhua qhov kev hloov pauv li cas lub laum me ntsis ua haujlwmnti khiav tawm, txiav quab yuam, thiab stability.
Vim li cas Helix Angle Matters hauv Drilling?
Thaum lub sijhawm drilling, ob yam yuav tsum tshwm sim tib lub sijhawm:
Cov npoo txiav tshem tawm cov khoom.
Cov flutes nqa chips tawm ntawm lub qhov.
Yog tias cov chips tsis tuaj yeem khiav tau zoo, kev sib txhuam nce, cua sov tsim, thiab drilling ua qeeb qeeb los yog ua tsis tau.
Lub kaum sab xis helix pab tswjsai npaum li cas chips txav tawm ntawm lub qhov.
Tsawg Helix Lub kaum sab xis rau cov ntaub ntawv nyuaj
Drill bits nrogqis helix kaumfeem ntau yog siv rau cov ntaub ntawv nyuaj xws li:
hardened hlau
nrum hlau
qee yam khoom siv sib xyaw
Lub kaum sab xis me me ua rau lub cev muaj zog dua thiab txo qhov nyiam ntawm qhov me me los tuav cov khoom. Qhov no txhim kho kev ruaj ntseg thaum drilling cov ntaub ntawv tawv uas tsim cov chips luv luv.
Tsawg helix designs kuj nce qhovstructural rigidity ntawm laum, ua rau lawv resistant rau breakage nyob rau hauv siab txiav quab yuam.
Standard Helix Angles rau General Drilling
Feem ntautwist laum khoom siv rau hlau drillingmuaj helix kaum ib ncig25-30 ° C.
Cov kab no muab kev sib xyaw ua ke ntawm:
kev tshem tawm nti zoo
zoo drilling stability
nruab nrab txiav quab yuam
Vim qhov sib npaug no, cov qauv helix cov ces kaum feem ntau yog siv rauGeneral -Lub hom phiaj HSS laum khoom, ua rau lawv haum rau ntau yam ntaub ntawv xws li me me hlau, txhuas, thiab yas.
High Helix Angles rau cov ntaub ntawv mos
Drill bits nrogsiab helix kaumyog tsim los rau cov ntaub ntawv softer uas tsim cov chips ntev, txuas ntxiv, suav nrog:
aluminium
tooj liab
yas
qee cov hlau mos
Ib tug steeper kauv pab txav cov chips ntev sai sai tawm ntawm lub qhov, tiv thaiv clogging.
High helix designs kuj txo cov kev sib txhuam ntawm lub laum thiab lub qhov phab ntsa, tso cai rau smoother drilling thiab txhim kho nto tiav.
Helix Angle kuj cuam tshuam rau kev txiav ceev thiab ruaj khov
Tshaj li nti nti khiav tawm, helix lub kaum sab xis kuj cuam tshuam:
Txiav efficiency
Lub kaum sab xis helix siab dua tuaj yeem ua rau kev txiav aggressiveness hauv cov ntaub ntawv softer.
cuab yeej zog
Lub kaum sab xis helix tsim muaj zog xyaum cores.
Kev vibration tswj
Optimized helix geometry tuaj yeem txo kev sib tham thiab txhim kho qhov raug.
Vim li no, laum me ntsis manufacturers ua tib zoo xaiv lub kaum sab xis helix nyob ntawm daim ntawv thov npaj.
Helix Angles nyob rau hauv Tshwj xeeb Drill Bits
Cov ntawv thov sib txawv drilling xav tau cov qauv helix sib txawv.
Piv txwv li:
Parabolic flute laum khoomsiv cov flutes sib sib zog nqus thiab hloov cov kaum sab xis rau qhov tob- qhov drilling.
Rauj laum khoom rau pob zebfeem ntau siv cov tshuab raj dav dav kom tshem tawm cov plua plav thiab cov khib nyiab sai sai.
High -kev xyaum hlau ua haujlwmtuaj yeem siv lub kaum sab xis helix sib txawv los txhim kho nti tswj.
Cov kev hloov pauv no qhia tau hais tias kev xyaum geometry zoo li cas rau cov kev sib tw tshwj xeeb.
Kev xav zaum kawg
Lub kaum sab xis ntawm lub helix yuav zoo li cov qauv tsim me me, tab sis nws muaj kev cuam tshuam loj rau kev ua haujlwm drilling.
Los ntawm kev kho lub kaum sab xis helix, laum me ntsis tus tsim qauv tuaj yeem tswj tau:
nti khiav tawm
txiav efficiency
cuab yeej zog
drilling stability
Qhov no yog vim li cas laum cov khoom tsim los rau cov khoom sib txawv feem ntau zoo sib xws thaum xub thawj siab ib muag tab sis ua tau txawv heev hauv kev xyaum.
Kev nkag siab txog cov qauv tsim no pab cov kws tshaj lij xaiv qhov kev xyaum zoo rau txoj haujlwm-thiab piav qhia tias vim li cas cov cuab yeej tshwj xeeb feem ntau ua tau zoo tshaj - lub hom phiaj.
