Hom Drill Bits

Lub laum me ntsis yog ib yam khoom siv rau kev ua haujlwm drilling, thiab daim ntawv thov ntawm cov laum me ntsis hauv kev ua pwm yog qhov tshwj xeeb;ib tug zoo xyaum me ntsis kuj muaj feem xyuam rau tus nqi ntawm cov pwm.Yog li dab tsi yog hom kev xyaum xyaum hauv peb cov pwm ua??

Ua ntej ntawm tag nrho cov, nws muab faib raws li cov khoom ntawm lub laum ntsis, uas feem ntau yog muab faib ua:

High-speed steel xyaum (feem ntau yog siv rau cov ntaub ntawv softer thiab ntxhib drilling)

Cobalt-muaj cov khoom siv laum (feem ntau yog siv rau kev ua haujlwm ntxhib ntawm cov ntaub ntawv nyuaj xws li stainless hlau thiab titanium alloys)

Tungsten steel / tungsten carbide xyaum (rau kev kub ceev, siab hardness, high-precision qhov ua)

Raws li lub laum ntsis system, feem ntau:

Ncaj shank twist xyaum (qhov feem ntau xyaum xyaum)

Micro-inch drills (tshwj xeeb xyaum rau me me diameters, cov hniav txoj kab uas hla yog feem ntau ntawm 0.3-3mm)

Kauj ruam laum (tsim rau ib-kauj ruam tsim ntawm ntau-kauj ruam qhov, txhim kho kev ua hauj lwm efficiency thiab txo nqi ua)

Raws li txoj kev txias, nws muab faib ua:

Direct txias laum (sab nraud pouring ntawm coolant, feem ntau drills yog ncaj qha txias xyaum)

Internal txias laum (lub laum muaj 1-2 cua txias los ntawm lub qhov, thiab lub coolant dhau los ntawm lub qhov txias txias, uas zoo heev txo cov cua sov ntawm lub laum thiab lub workpiece, haum rau high-hard cov ntaub ntawv thiab xov)
