Hom drills rau hlau - uas xyaum xyaum xaiv?
Txheem
Kev lees paub ntawm lub qhov ua tau zoo hauv cov hlau yog ib qho kev xyaum xaiv zoo. Nyob ntawm cov khoom siv raw thiab cov cuab yeej clamping, ntau hom kev ua haujlwm txuas tau raug xaiv hauv cov cuab yeej txiav. Dab tsi xyaum ua rau hlau tuaj yeem paub qhov txawv? Dab tsi yog qhov zoo tshaj plaws rau hom haujlwm no?
Zoo hlau xyaum - yuav ua li cas paub lawv?
Lub parameter uas txawv qhov piav qhia los ntawm cov uas npaj rau lwm yam ntaub ntawv yog lub kaum sab xis ntawm inclination ntawm laum, i.e. txoj hauj lwm ntawm cov hniav txiav nyob rau hauv kev sib raug zoo rau ib leeg. Kev kub ceev steel txiav cov cuab yeej muaj tus nqi angular ntawm 118 degrees. Ua tsaug rau nws, kev ua haujlwm siab tshaj plaws ntawm cov khoom ua tiav tiav.
Lwm qhov tseem ceeb parameter yog cov khoom siv los ntawm kev xyaum ua. Ib qho ntawm lawv yog HSS steel hais los saum toj no, nrog rau cov hlau tsis huv ntawm cobalt thiab titanium. Qee cov ntsiab lus txiav yog ua los ntawm vanadium-molybdenum lossis chrome-vanadium hlau. Tus yuam sij rau kev xaiv yog txiav txim siab qhov hardness ntawm cov khoom thiab txoj kab uas hla ntawm lub qhov yuav tsum tau ua.
Drills rau hlau - yam ntxwv ntawm tus kheej hom
Hauv qab no yog cov neeg sawv cev tseem ceeb ntawm kev xyaum xyaum, uas yog cov nyiam tshaj plaws ntawm kev ua lag luam. Nws yog cov khoom siv raw los ntawm lawv tau tsim los txiav txim siab txog hom khoom siv uas tuaj yeem drilled nrog lawv yam tsis muaj kev ntshai ntawm kev puas tsuaj.
Heev ruaj titanium hlau xyaum
Nyiam titanium xyaum xyaum lawv muaj txiaj ntsig tshwj xeeb thaum tuav cov khoom hnyav. Ua tsaug rau kev siv titanium nitride uas lawv tau coated, muaj kev tiv thaiv siab heev rau kev puas tsuaj thiab kub kub. Qhov no ua rau lawv nyiam los ntawm cov neeg txawj ntse thiab kev lag luam uas kev ntseeg siab yog tus yuam sij rau kev ua haujlwm tau zoo. Ntawm cov qauv uas muaj rau kev siv txhua hnub, txoj cai tho HSS - TI hom N sawv tawm.
Titanium cov khoom tsim nyog rau kev txiav cov hlau (tshwj tsis yog aluminium alloy thiab caij nplooj ntoos hlav steel) thiab acrylic iav, feem ntau hu ua plexiglass. Cov neeg tsim khoom pom zoo kom siv cov cua txias thaum ua haujlwm nrog lub laum, uas, nyob ntawm cov khoom siv, tuaj yeem yog dej (yas) lossis emulsions thiab lubricants (hlau).
Cobalt Precision Drills
siab zoo cobalt xyaum Lawv yog siv, tshwj xeeb tshaj yog thaum ua qhov nyob rau hauv tshav kub-resistant, corrosion-resistant thiab stainless hlau. Tsis zoo li titanium drills, feem ntau txiav hniav lub kaum sab xis yog 135 degrees. Ua tsaug rau qhov no, tsis tas yuav tho qhov qhov ua ntej ua ntej siv cov qauv piav qhia.
Lub xub ntiag ntawm cobalt impurity ua rau qhov tseeb tias cov khoom siv txiav tau txais kev tiv thaiv ntau dua rau qhov kub thiab txias thiab muaj qhov ua kom muaj kev pab cuam lub neej ntau dua piv rau cov hlau ntshiab siab ceev. Self-centering zog pab tshem tawm qhov tshwm sim ntawm zawv zawg qhov xyaum ntawm qhov chaw ntawm cov khoom ua tiav. Titanium thiab cobalt xyaum xyaum tsim los ua haujlwm nrog cov khoom siv, yog li lawv feem ntau xaiv los ntawm cov kws tshaj lij.
Universal xyaum rau cov ntaub ntawv mos.
Ib hom tshwj xeeb ntawm kev xyaum hlau rau kev siv ib nrab yog HSS accessories. Lawv tsis tshua muaj peev xwm ua haujlwm kub txog 400 degrees Celsius. Rau cov neeg uas txiav cov hlau ib ntus lossis tsuas yog siv cov xyaum ua haujlwm kho tsev, cov no yog cov khoom siv zoo. Lawv lub kaum sab xis yog 118 degrees, uas txhais tau hais tias kom ua tiav qhov tsim nyog qhov ntev thiab qhov nruab nrab ntawm lub qhov, nws tsim nyog ua ntej tho nws nrog lub cuab yeej me.
Kev kub ceev steel HSS yam tsis muaj kev sib xyaw ntawm lwm cov khoom siv raw pab txo tus nqi ntawm cov khoom kawg. Yog li ntawd, lub siab xav yuav zoo laum khoom rau hlau tsis siv nyiaj ntau, nws tsim nyog xav txog cov hom khoom siv no.
Lwm hom kev xyaum hlau
Nrov hom kev xyaum muaj xws li xyaum xyaum nrog tig mounting kov. Cov no yog HSS steel ntsia hlau accessories uas tuaj yeem siv rau hauv cov tho me me. Lawv zoo heev rau kev ua qhov loj hauv cov hlau nrog cov txheej txheem txiav.
Lwm tus qauv conical laum rau hlau. Nws kuj yog qee zaum hu ua tsob ntoo Christmas, theem lossis ntau theem. Lub npe nomenclature los ntawm nws cov yam ntxwv zoo, uas tso cai rau lub qhov ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv cov ntawv hlau thiab cov kav dej. Vim nws tus kheej-centering zog ntawm lub laum, nws yog siv tsis tau pre-drilling cov khoom. Lub xub ntiag ntawm cov hniav qis thiab ob sab hniav ua kom muaj qhov chaw xyaum ruaj khov txawm tias thaum ua cov kav hlau oval.
Countersinks yog zoo tagnrho rau reaming qhov nyob rau hauv nyuaj hlau xws li hlau, cam khwb cia hlau thiab yas. Vim yog kev txiav cov ntaub ntawv nyuaj, lawv feem ntau yog ua los ntawm HSS-Ti steel. Lawv yog cov heev resistant rau huab cua kub thiab puas. Lawv zom zoo heev thiab tob zuj zus ua ntej ua qhov.
Txoj kev fastening xyaum rau hlau
Dab tsi xyaum rau hlau xaiv rau ib qho khoom siv tshwj xeeb? Yeej, muaj 4 hom cuab yeej txuas hauv lub cuab yeej. Cov no yog cov cwj mem:
- morse,
- ceev mount,
- SDS-MAX,
- SDS-PLUS.
Morse taper chuck yog ib feem ntawm kev xyaum thiab reamers uas tau nruab rau hauv cov cuab yeej siv tshuab. Cov txheej txheem ntawm fastening xws li fittings nyob rau hauv pab kiag li lawm pab rau kev hloov ntawm lub sij hawm loj loj nrog kev pab los ntawm ib tug tshwj xeeb ntsia tuav nyob rau hauv daim ntawv ntawm ib tug ncej.
Thaum laum khoom rau hlau rau cov cuab yeej nrog tus kheej-locking chuck, lawv yog nyob rau hauv daim ntawv ntawm ib tug pas nrig nrog tib txoj kab uas hla. Lawv yog cov cuab yeej siv dav tshaj plaws rau kev siv lub hom phiaj dav dav.
Qhov xwm txheej txawv nrog SDS tus tuav. Lawv feem ntau yog siv nyob rau hauv teb rauj thiab yog siv los tuav tshwj xeeb tsim laum khoom. SDS-PLUS yog siv hauv cov ntawv thov tsawg dua thiab hnav, thaum SDS-MAX tuaj yeem ua kom haum rau cov tho qhov loj dua 18mm.
Thaum nrhiav kev xyaum zoo rau cov hlau, nws tsim nyog teb cov lus nug ntawm lawv daim ntawv thov yuav ua li cas. Yog tias koj ua qhov nrog cov diameters rov ua dua thiab tsis muaj ntau dhau lawm, koj tuaj yeem ua qhov teeb tsa koj tus kheej. Txwv tsis pub nws yuav los ua ke txheej laum khoom rau hlau
