Peb feem ntau hnov los ntawm cov neeg siv khoom uas hais tias, "Kuv xav tau 6.2 hli laum me ntsis - yog dab tsi hauv tus qauv loj?"
Nws suab zoo li ib lo lus nug yooj yim, tab sis nws qhib ib qho kev tsis meej pem loj tshaj plaws hauv lub ntiaj teb drilling:vim li cas thiaj muaj ntau yam qauv sib txawv?
Cia peb muab nws ua ke.
Vim li cas thiaj muaj qhov sib txawv Drill Size Systems?
Cov lus teb nyob rau hauvkeeb kwm thiab geography [1].
Hauv Tebchaws Europe thiab feem ntau ntawm Asia, lubmetric systemdominates kev tsim khoom. Txhua yam yog ntsuas hauv millimeters. Yooj yim, logic, universal.
Nyob rau hauv sib piv, lubimperial system- siv feem ntau hauv Teb Chaws Asmeskas- cia siab raufeem ntawm ib nti(xws li 1/4", 3/8") thiabxov tooj cua ntsuas(#29, #40, thiab lwm yam), uas hnub rov qab mus rau 19th -century wire- ua qauv.
Tias yog vim li cas tib lub laum me ntsis tuaj yeem muaj peb txoj kev sib txawv ntawm kev piav qhia - nyob ntawm seb koj nyob qhov twg.
Thaum American engineers tham txog ib"standard laum", lawv feem ntau txhais tau tiasfractional -inch lossis xaim- ntsuas qhov ntau thiab tsawg.
Thaum ib tug European lossis Australian machinist hais"standard laum", lawv txhais tau tiasmetric qhov ntau thiab tsawg.
Yog li, yog tias koj ua haujlwm thoob plaws cheeb tsam - lossis cov cuab yeej siv thoob ntiaj teb - nws yooj yim pom tias muaj kev ntxhov siab li cas.
[1] Raws li Wikipedia 'Drill me ntsis qhov ntau thiab tsawg' nkag, metric, fractional ntiv tes, thiab xaim- ntsuas tshuab qhia txog cov qauv hauv cheeb tsam thiab keeb kwm kev tsim khoom.
Metric - mus rau -Standard Conversion Table (3.3 mm txog 16.5 mm)
| Metric (mm) | Closest Fractional (nti) | Tus lej ze tshaj / Tsab ntawv | Saib |
|---|---|---|---|
| 3.3mm ib | 1/8" (0.1250") | #30 (0.1285") | #30 yog kev sib tw nruj dua |
| 3.5mm ib | 9/64" (0.1406") | #29 (0.1360") | Siv #29 kom nruj dua |
| 5.2mm ib | 13/64" (0.2031") | #7 (0.2010") | #7 yog ze heev |
| 6.2mm ib | 15/64" (0.2344") | #1 (0.2280") | Me ntsis undersize yog siv #1 |
| 6.5mm ib | 1/4" (0.2500") | - | Xyaum interchangeable |
| 6.8mm ib | 17/64" (0.2656") | - | Siv yog tias kev tso cai tso cai |
| 8.5mm ib | 21/64" (0.3281") | - | Muaj nyob rau hauv metric hardware |
| 10.5 hli | 13/32" (0.4063") | - | Feem ntau siv rau tapping M12 xov |
| 16.5mm 3 | 21/32" (0.6563") | - | Hom rau loj los ntawm qhov |
Nco tseg: Kev hloov dua siab tshiab yog kwv yees li - ib txwm txheeb xyuas nrog kev ua siab ntev ua ntej tsim khoom.
Xav paub txog 4 hli kev hloov pauv thiab thaum twg koj tuaj yeem hloov pauv yam nyab xeeb? Mus saib peb tsab xov xwm dhau los, "4 hli Laum hauv Imperial - Koj Puas Xav Tau Metric Drill Bit?", qhov twg peb tshawb nrhiav qhov teeb meem tiag tiag los ntawm cov neeg tsim khoom qhov kev xav.
Yam Koj Yuav Tsum Siv - Metric lossis "Standard"?
Nov yog peb txoj cai ntawm tus ntiv tes xoo tom qab xyoo ua haujlwm nrog cov neeg xa khoom thoob ntiaj teb:
Yog hais tias koj nyob nraum txuam ib daim duab uas twb muaj lawm los yog ib feem, lo nrog lubtus qauv qub. Tsis txhob sib xyaw tshuab tshwj tsis yog koj paub tseeb.
Rau qhov dav - lub hom phiaj lossis ntawm - qhov chaw drilling, kaw imperial sib npaug (xws li 1/4 "rau 6.5 hli) feem ntau tau txais.
Rau precision sib dhos, tapping, lossis CNC machining, ib txwm siv lubraws nraim metric ntsis- qhov sib txawv me me tuaj yeem ua rau muaj teeb meem haum lossis kam rau ua tom qab.
Ib tug ntawm peb cov neeg muag khoom nyob sab Europe ib zaug tau hais rau peb tias, "Ua ntej hloov mus rau kev xyaum ua metric, peb tau nkim sij hawm rov kuaj xyuas kom haum. Tam sim no, peb tsuas yog xaj ncaj qha los ntawm millimeter."
Nws yog qhov hloov me me, tab sis nws tau cawm lawv suav tsis txheeb reworks thiab cov khoom tsis sib haum.
Qhov txawv hauv cheeb tsam: Vim li cas qhov tsis meej pem tseem nyob
HauvU.S., feem ntau thiab tus lej xyaum yog tseem mus - rau tus qauv rau kev tsim khoom thiab kho cov khw. Cov khw muag khoom kho vajtse sau 1/8", 3/16", 1/4"-tab sis tsis tshua muaj 3.3 hli lossis 6.2 hli.
Meanwhile, hauvEurope, UK, thiab Australia, metric sizing yog tag nrho standardized (ISO 235)[1]. Yog li 6.2 hli me ntsis tsuas yog… 6.2 hli.
Qhov kev tsis sib haum xeeb no ua rau "teeb meem kev txhais lus" peb pom ntau zaus hauv online - tshwj xeeb tshaj yog thaum cov engineers hauv ib lub teb chaws nyeem specs sau rau lwm tus.
[1] ISO 235 qhia cov laum qhov ntev hauv mm thiab ntiv tes rau qhov sib npaug -shank laum.Raws li ISO 235: 2016, laum qhov ntev yog tus qauv hauv ob millimeter thiab nti units, txhais cov haujlwm thiab cov stub series

Yog tias koj puas tau pom koj tus kheej xav paub seb koj qhov kev xyaum 6.2 hli sib npaug li 15/64 "los yog #1 - lo lus nug tiag tiag yuav yog:vim li cas ho tsis siv 6.2 hli me ntsis uas tau ua rau txoj haujlwm?
