Thaum cov kws ua choj thiab cov neeg yuav khoom teev cov cuab yeej siv DIN 333, ib qho ntawm cov lus nug feem ntau uas peb tau txais yog: "Qhov txawv ntawm Hom A thiab Hom B yog dab tsi - thiab kuv xav tau qhov twg tiag?"
Nws yog ib lo lus nug ncaj ncees. Ob hom no muaj tib lub kaum sab xis 60°, ua raws li tus qauv DIN 333 tib yam, thiab muaj cov ntaub ntawv zoo ib yam. Tab sis muaj qhov sib txawv ntawm geometric ntawm lawv - ib qho uas muaj feem cuam tshuam ncaj qha rau qhov koj lub qhov nruab nrab tuav tau zoo li cas los ntawm cov txheej txheem machining.
Phau ntawv qhia no piav qhia txog qhov sib txawv kom meej meej, nrog rau DIN 333 cov lus qhia rau ob hom.
Lub DIN 333 Center Drill yog dab tsi?
Lub tshuab laum nruab nrab — tseem hu ua lub tshuab laum sib xyaw thiab lub tshuab countersink — yog siv los tsim lub qhov conical 60° kom raug ntawm qhov kawg ntawm ib qho workpiece ua ntej tig ntawm cov chaw nruab nrab ntawm lub tshuab lathe. Lub qhov nruab nrab muab qhov chaw zaum ruaj khov rau lub chaw nruab nrab ntawm lub tailstock, kom ntseeg tau tias muaj concentricity thiab qhov tseeb ntawm qhov chaw thoob plaws kev tig, kev sib tsoo, lossis kev sib tsoo tom qab.
DIN 333 yog tus qauv German (Deutsches Institut für Normung) uas tswj hwm cov geometry, qhov ntev, thiab kev kam rau ntawm 60 ° center drills. Nws txhais peb hom: Hom A, Hom B, thiab Hom R. Tsab xov xwm no tsom mus rau ob hom feem ntau teev tseg: A thiab B.
Qhov Sib Txawv Ntawm Lub Core: Ib Chamfer vs. Ob
Cov Lus Qhia Ceev: Hom A piv rau Hom B

Cov Kev Xaiv Khoom Siv: M2 vs. M35
Ob qho tib si Hom A thiab Hom B lub tshuab laum nruab nrab muaj ob qib HSS. Kev xaiv cov khoom siv tsis yog nyob ntawm hom - nws nyob ntawm cov khoom siv ua haujlwm thiab qhov ntau lawm.
M2 HSS — Qib Txheem
M2 (HS6-5-2) yog qib HSS uas siv dav tshaj plaws thoob ntiaj teb. Nws muaj kev tawv zoo, tiv taus kev hnav, thiab kev ua haujlwm zoo sib xws thoob plaws ntau yam khoom siv ua haujlwm - hlau tsis muaj zog, txhuas, hlau cam khwb cia, tooj liab, thiab feem ntau cov hlau uas tsis yog hlau. M2 center drills yog qhov kev xaiv txheem rau cov chaw ua haujlwm dav dav.
M35 HSS-Co — Cobalt Qib rau Cov Ntawv Thov Uas Xav Tau Ntau
M35 (HS6-5-2-5, tseem hu ua HSSCo5) ntxiv 5% cobalt rau hauv paus M2. Qhov no ua rau qhov tiv taus cua sov mus txog li 630–650°C thiab ua rau qhov nyuaj mus txog 63–66 HRC. M35 yog qib nyiam dua thaum muab cov hlau tsis xeb, hlau sib xyaw, lossis lwm yam khoom siv uas nyuaj rau tshuab, lossis hauv kev tsim khoom ntau qhov twg lub neej cuab yeej yog qhov tseem ceeb.
Cov Kev Xaiv Ua Kom Tiav Nto
Yuav Xaiv Li Cas: Phau Ntawv Qhia Txog Kev Txiav Txim Siab Uas Siv Tau Zoo
Yog tias koj tab tom teeb tsa qhov chaw ua haujlwm uas yuav tig tam sim ntawd hauv tib qho kev teeb tsa, Hom A yog qhov kev xaiv zoo. Nws yooj yim dua, luv dua me ntsis, thiab npog feem ntau ntawm cov ntawv thov teeb tsa qhov chaw tshuab dhos.
Yog tias koj txoj kev ua haujlwm muaj ib qho ntawm cov hauv qab no, qhia hom B:
• Cov khoom ua haujlwm txav mus los ntawm cov tshuab lossis hloov pauv ntawm kev ua haujlwm
• Cov khoom raug khaws cia lossis tuav tom qab nruab nrab thiab ua ntej tig zaum kawg
• Koj qhov kev kam rau siab xav tau qhov geometry ntawm qhov chaw nruab nrab uas sib xws, rov ua dua tau thoob plaws hauv kev tsim khoom
• Koj ua haujlwm nrog cov shafts uas qhov runout ntawm lub qhov chaw nruab nrab puas lawm tsis raug lees txais
Thaum tsis paub meej, Hom B yog qhov kev qhia tshwj xeeb uas muaj kev nyab xeeb dua. Lub chamfer tiv thaiv ntxiv tsis ntxiv qhov nyuaj rau kev ua haujlwm drilling nws tus kheej - nws tsuas yog ua kom ntseeg tau tias qhov chaw zaum tseem zoo.
