Dab tsi yog vim li cas thiaj yooj yim tawg thaum Drilling nrog Carbide Laum khoom?

Laum breakage yog ib qho tshwm sim tsis tuaj yeem, thiab txhawm rau tiv thaiv nws qhov tshwm sim tsis tu ncua, qhov zoo tshaj plaws uas peb tuaj yeem ua tau yog nkag siab txog qhov ua rau kev sib tsoo tawg, daws cov teeb meem, thiab xaiv cov kev sib tw zoo dua rau kev ua haujlwm drilling. Yog li, dab tsi yog qhov laj thawj tseem ceeb tom qab twist laum breakage?
Hard hlau laum khoom yuav tsum tau ua tib zoo xav txog cov khoom sib xws hauv cov txheej txheem txiav. Qhov no txhais tau hais tias seb cov khoom siv ntawm qhov sib tw yog tsim nyog rau machining cov khoom ntawm lub workpiece. Piv txwv li, siv cov qib siab zoo ib yam li 6542 lossis 4241 los ua cov khoom siv hlau tsis zoo xws li 303 lossis 304 yog qhov tseem ceeb tsis muaj txiaj ntsig- nws zoo li pov qe tawm tsam phab ntsa pob zeb. Thaum cov khoom siv laum tsis tuaj yeem kov yeej cov khoom siv ua haujlwm, txuas ntxiv drilling nyob rau hauv kev cuam tshuam yuav inevitably rhuav tshem qhov sib tw. Qhov no yog ib qho taw qhia: tsis ua hauj lwm rau nkag mus thiab tsis tu ncua drilling ua rau yooj yim tawg.
Qhov thib ob tshwm sim tuaj yeem raug ntaus nqi rau cov khoom xaiv ntawm covtwist xyaumua tsis zoo rau machining ib puag ncig thiab cov khoom siv. Hard alloy yog cov khoom siv raw khoom siv rau kev sib tw twist. Raws li paub zoo, alloy twist xyaum ua kom muaj zog thiab hnav tsis kam tab sis tsis muaj zog, ua rau lawv tsis haum rau tes - tuav cov khoom siv drilling. Txawm li cas los xij, txawm tias cov cuab yeej siv tshuab drilling tuaj yeem muaj kev tawg. Muaj ob lub laj thawj tseem ceeb: ua ntej, cov khoom siv ua haujlwm feem ntau muaj cov impurities, qee qhov muaj cov ntsiab lus siab noo noo, ua rau tawg thiab tawg ntawm cov hlau laum me ntsis. Thib ob, tus thawj hard alloy twist xyaum muaj ntau heev hardness, uas yog incompatible nrog cov khoom ua tiav. Lwm qhov tseem ceeb cuam tshuam nrog kev ruaj ntseg ntawm cov cuab yeej- tsis yog cov cuab yeej siv ceev ceev tuaj yeem siv tau zoo nrog siab - zoo alloy twist drills, tab sis theej tswj kom ruaj khov runout thiab concentricity ntawm cov cuab yeej.
Txhawm rau ua kom tau zoo drilling nrog carbide laum khoom, xaiv qhov tsim nyog yog qhov tseem ceeb. Tsis tas yuav blindly xaiv qhov kev xaiv kim tshaj plaws; hloov, nws yuav tsum ua raws li cov xwm txheej tiag tiag. Thaum xaiv ib qho kev sib tw twist, xav txog peb yam: cov khoom ua tiav, cov khoom siv, thiab qhov tseeb lub qhov taub thiab qhov tob.
