1. Tustus kaisZoo tsis zoo
Cov ntaub ntawv tseem ceeb, kev tsim kho tshuab, kev kho cua sov, kev hloov pauv tau yooj yim lossis qhov loj me, thiab nws yog qhov yooj yim los ua kom tawg thaum siv cov kev siv. Kev hloov pauv ntawm kev sib tshuam ntawm Shank thiab cov hniav dhau ntawm kev hloov pauv ntawm Weld, ua rau muaj kev ntxhov siab loj, uas ua rau tus kais kom tawg thaum siv thaum siv. Piv txwv li, cov txheej txheem kho cua sov ua kom sov. Thaum tus kais yog cov kho cua sov, yog tias nws tsis yog preheated ua ntej quenching thiab ntau dua tawg, tsis yog txias, nws yuav ua rau cov kab mob tawg. Rau ib qho loj, qhov no tseem yog ib qho laj thawj tseem ceeb vim li cas thiaj ua tau kev ua tau zoo ntawm cov kaus mom hauv tsev tsis zoo li cov kais dej txawv.
Countermekasures: Xaiv cov kais dej zoo thiab txhim khu kev qha
2. Kev xaiv tsis raug cai ntawmtus kais dej
Rau tapping seem nrog ntau dhau hardness, cov taps zoo yuav tsum tau siv, xws li cobalt-muajHigh-ceev steel taps, carbide taps, coated taps, etc. Ntxiv rau, tus kais tsim qauv tau siv nyob rau cov xwm txheej sib txawv. Piv txwv li, tus lej, loj, kaum, thiab lwm yam ntawm lub taub hau flute ntawm tus kais dej ntawm tus neeg muaj kev cuam tshuam rau kev tshem tawm nti.
Rau cov ntaub ntawv nyuaj-rau-tshuab xws li cov nag lossis daus los nrog lub zog nyuaj thiab tsis txaus ntseeg thiab tsis tuaj yeem tiv thaiv cov kev ua qauv tapping.
Ib qho ntxiv, qhov teeb meem ntawm cov tsis sib xws ntawm tus kais thiab cov khoom ua tau them ntau dua thiab ntau dua rau xyoo tsis ntev los no. Yav dhau los, cov chaw tsim khoom hauv tsev ib txwm xav tias cov khoom lag luam txawv teb tau zoo dua thiab kim dua, tab sis lawv tau tsim nyog. Nrog kev nce ntxiv ntawm cov ntaub ntawv tshiab thiab kev ua nyuaj, txhawm rau kom tau raws li kev thov no, ntau yam cuab yeej siv tau nce ntxiv. Qhov no yuav tsum xaiv cov khoom siv kais tsim nyog ua ntej tapping.
Countermekasures: Siv cov kais dej high-zog cov khoom siv (xws li hmoov cov hmoov kub siab ultrasonic, thiab lwm yam) los txhim kho lub zog ntawm tus kais nws tus kheej; Nyob rau tib lub sijhawm, txhim kho cov txheej saum npoo ntawm cov kais kom txhim kho cov npoo tawv tawv ntawm cov xov; Nyob rau hauv cov neeg mob hnyav, txawm tias phau ntawv tapping tej zaum yuav ua tau.
3. Kev hnav ntau dhau ntawm covtus kais
Tom qab cov kais ua tiav ntau lub qhov ua rau muaj ntau lub qhov, cov kev txiav tawm tsam vim qhov hnav ntau dhau ntawm cov kais dej, uas ua rau tus kais tawg.
Countermekasures: Kev siv cov khoom siv zoo tapping lubricating kuj tseem ua tau zoo rau kev hnav tus kais; Tsis tas li ntawd, kev siv cov xov Xov (T / Z) yooj yim txiav txim rau cov kais dej.
4. Nyuaj rau hauv nti tawg thiab nti tshem tawm
Rau qhov muag tsis pom tapping, ib kauv zuaj zeem muag lub nraub qaum lwj feem ntau siv. Yog tias cov hlau hlau qhwv tau qhwv ib ncig ntawm cov kais thiab tsis tuaj yeem tawm tsam du, thiab cov hlau loj (xws li cov hlau thiab stainless thiab lwm yam. Machining yog feem ntau nyuaj rau tawg chips.
Countermekasures: Thawj kev xav hloov lub Helix kaum sab xis ntawm cov kais dej (feem ntau muaj ntau qhov sib txawv helix ces kaum sib txawv los ntawm), sim ua kom cov mlom filings tau tshem tawm txoj kev nruj heev; Nyob rau tib lub sijhawm, kho cov kev txiav tsis tsim nyog, lub hom phiaj yog ua kom ntseeg tau tias cov ntawv lim hlau tuaj yeem tshem tawm yooj yim; Yog tias tsim nyog nce mus sib txawv helix lub npov tau raug xaiv kom ntseeg tau tias du tawm ntawm cov ntawv pov tseg hlau.
