Laum Ntev Taper Shank Laum Ntev Twist Laum HSS6542
Lub tshuab laum hlau ceev ceev yog lub cuab yeej rau kev laum cov qhov puag ncig ntawm ib txoj haujlwm daim los ntawm kev tig thiab txiav piv rau ib txoj kab ruaj khov. Nws tau muab lub npe vim yog cov duab ntawm cov flutes chip, uas zoo li twists. Spiral grooves muaj 2 grooves, 3 grooves lossis ntau dua, tab sis 2 grooves yog qhov feem ntau. Twist drills tuaj yeem clamped ntawm tes thiab hluav taws xob tes tuav drilling cuab yeej lossis drilling tshuab, milling tshuab, lathes thiab txawm tias machining chaw. Cov khoom siv ntawm high-speed steel twist drill yog high-speed steel (HSS).
Tsim cov khoom siv hluav taws xob sib xyaw ua ke, tsim cov khoom siv hluav taws xob sib xyaw, yooj yim txiav, tsis yooj yim lo rau riam, kom ua tiav cov txheej txheem ua haujlwm siab. daim muaj qhov tseeb dua thiab ci ntsa iab.
Muaj zog kho cua sov, hnav tsis kam thiab ua haujlwm ntev, siv dav
Txo qhov kev sib txhuam coefficient ntawm kev khawb, qhov tseeb siab, phab ntsa du
