Yuav ua li cas xaiv txoj cai twist laum rau drilling sib txawv substrates

Xaiv cov khoom siv twist zoo yog qhov tseem ceeb rau kev ua haujlwm zoo, meej drilling hla cov substrates sib txawv. Nov yog cov lus qhia rau kev sib piv cov ntaub ntawv nrog cov tho hom:

Rau cov hlau, qhov kev xaiv hinges ntawm hardness. Cov hlau me me thiab txhuas ua haujlwm tau zoo nrog cov qauv High-Speed ​​Steel (HSS) xyaum, uas muaj qhov zoo toughness thiab nruab nrab kub tsis kam. Rau cov hlau hnyav xws li stainless hlau, cam khwb cia hlau, lossis hlau alloy, HSS-Co (HSS nrog cobalt) zoo dua. Qhov sib ntxiv ntawm cobalt txhim kho cov cua sov ua haujlwm, tso cai rau cov drilling ceev dua yam tsis muaj cua sov los yog dulling

Thaum drilling ntoo, carbon steel laum yog tus nqi - zoo rau cov ntoo mos zoo li ntoo thuv, vim lawv nyob twj ywm nrog kev sib txhuam tsawg heev. Rau cov ntoo tawv tawv xws li ntoo qhib lossis maple, HSS xyaum zoo dua -lawv cov kav ntev tiv taus hnav los ntawm cov fibers ntom ntom, ua kom lub qhov huv huv thiab lub neej ntev dua.

Rau cov yas (piv txwv li, PVC, acrylic), ntse HSS xyaum yog nyiam. Lawv cov kev sib txhuam qis txo cov cua sov tsim, tiv thaiv cov yas los ntawm melting los yog chipping. Tsis txhob siv cov ntaub ntawv nruj heev, vim tias lawv tuaj yeem tawg cov yas nkig

Abrasives zoo li fiberglass lossis composites xav tau carbide-tipped xyaum, tab sis cov no feem ntau ua ke nrog HSS shanks kom sib npaug. Carbide lub hardness withstands abrasive hais uas sai sai hnav cov qauv hlau

Cov txheej txheem (xws li TiN, TiAlN) tuaj yeem txhim kho kev ua tau zoo, tab sis cov khoom tseem ceeb tseem yog lub hauv paus. Sib piv cov khoom siv rau cov khoom siv tawv tawv thiab cov khoom sib xyaw ua kom lub neej ntev, precision, thiab txo cov cuab yeej hnav.
