Ib tug hlau laum me ntsis tuaj yeem laum tooj dag, tab sis muaj cov kev xav tshwj xeeb thiab kev hloov kho kom zoo thiab nyab xeeb drilling.
Cov ntsiab lus tseem ceeb rau Drilling Brass
1. Drill Bit Hom: Txheem twist laum khoom siv tau, tab sis lawv feem ntau xav tau kev hloov kho. Brass nyiam lob ntawm cov npoo ntse, uas tuaj yeem ua rau lub laum me ntsis snapping lossis lub workpiece spinning poob nthav. Nws raug nquahu kom siv cov khoom siv high-speed steel (HSS) cov khoom uas tau hloov kho kom muaj lub tiaj tiaj, tshem tawm lub kaum sab xis saum toj kawg nkaus uas feem ntau tshwm sim hauv cov khoom txheem.
2. Kev Hloov Kho Geometry: Txhawm rau txhim kho kev ua haujlwm thaum drilling tooj dag:
- Txo lub Rake Angle: Hloov kho qhov txiav ntug ntawm lubxyaum me ntsiskom muaj zero rake. Qhov kev hloov kho no pab tiv thaiv kev xyaum los ntawm kev tuav lub tooj dag thiab txhim kho nti tshem tawm.
- Point thiab di ncauj Angles: Lub kaum sab xis ntawm 90 thiab 118 degrees raug pom zoo, nrog rau lub kaum sab xis ntawm 12 thiab 26 degrees. Cov kev hloov kho no pab kom sib npaug aggressiveness thiab txo binding.
3. Drilling Technique:
Ceev thiab pub tus nqi: tooj dag yuav tsum tau drilled ntawm qis speeds piv rau steel, feem ntau nyob ib ncig ntawm 90-210 m/min. Kho tus nqi pub raws li tus laum me ntsis twist tus nqi kuj tuaj yeem txhim kho kev ua tau zoo.
Clamping lub Workpiece: Kev ruaj ntseg clamping ntawm tooj dag daim yog qhov tseem ceeb los tiv thaiv kev txav thaum lub sij hawm drilling, uas tuaj yeem ua rau tsis raug lossis raug xwm txheej.
4.Cooling thiab Lubrication: Thaum drilling tooj dag, lubrication feem ntau tsis tas yuav tsum tau; Txawm li cas los xij, siv cov roj nplua nyeem tuaj yeem pab txo kev sib txhuam thiab cua sov hauv qee kis. Nws yog ib qho tseem ceeb los saib xyuas cov nti tshem tawm- tooj dag yuav tsum tsim cov chips me me dua li ntev swarf.
Los ntawm kev ua raws li cov lus qhia no, cov cuab yeej siv hlau tuaj yeem ua tau zoo tho tooj dag yam tsis muaj kev pheej hmoo ntau dhau ntawm kev puas tsuaj lossis kev raug mob.
