Machining S690Q steel xav tau kev coj ua tshwj xeeb vim nws lub zog siab thiab hardness (feem ntau 240-300 HBW). Ua raws li cov lus qhia kom raug yog qhov tseem ceeb kom ua tiav cov txiaj ntsig zoo, tswj lub neej ntawm cov cuab yeej, thiab zam kev ua haujlwm nyuaj lossis kev puas tsuaj rau cov khoom siv.
1. Kev xaiv cov cuab yeej
Khoom siv: Siv cov khoom siv ua haujlwm siab - xws li Carbide (C2 / C3 qib) lossis Cermet. Rau hnyav roughing, coated carbides lossis txawm Ceramic inserts (rau kev txiav txuas ntxiv) tuaj yeem txiav txim siab.
Geometry: Cov cuab yeej yuav tsum muaj lub kaum sab xis zoo, cov npoo ntse ntse, thiab cov duab geometry muaj zog kom txo tau txiav quab yuam thiab tsim hluav taws xob.
Rigidity: Tag nrho cov teeb tsa (tshuab, workpiece, cuab yeej) yuav tsum nruj heev kom txo tau kev co thiab sib tham.
2. Kev Txiav Txim (Cov Lus Qhia dav dav)
Txiav ceev (Vc): Nruab nrab mus rau qis. Feem ntau hauv thaj tsam ntawm 80 - 150 m/min rau cov cuab yeej carbide. Pib ntawm qis kawg thiab kho raws li cov cuab yeej ua haujlwm.
Feed Rate (fn): Siv tus nqi pub kom txaus los tiv thaiv kev sib tsoo ntau dhau thiab ua haujlwm tawv. Lub teeb ci dhau lawm tuaj yeem ua rau lub ntsej muag ci thiab ua kom cov cuab yeej hnav.
Qhov tob ntawm Kev Txiav (ap): Siv qhov tob txaus ntawm kev txiav kom paub meej tias qhov kev txiav yog ua hauv qab ib qho kev ua haujlwm- txheej tawv tawv los ntawm kev hla dhau los.
3. Txheej txheem-Cov lus qhia tshwj xeeb
Tig: Xyuas kom ruaj ntseg clamping. Siv cov dej txias kom zoo. Chip breakers yog ib qho tseem ceeb vim tias cov khoom tuaj yeem tsim cov tawv tawv, txuas ntxiv mus.
Milling: Nyiam nce milling (down{0}}milling) dua li cov milling los txhim kho lub neej ntawm cov cuab yeej thiab qhov chaw tiav. Siv cov cuab yeej nrog txo tus naj npawb ntawm flutes kom zoo dua nti khiav tawm.
Drilling & Tapping:
Drilling: Siv siab - zoo carbide xyaum nrog cov duab geometry. Peck drilling yog pom zoo rau qhov tob tob kom tshem cov chips thiab txias cov cuab yeej.
Tapping: Nws yog kev ua haujlwm nyuaj. Siv cov kais dej tshwj xeeb tsim los rau siab - tensile steels, xyuas kom meej kev sib raug zoo, thiab xav txog xov milling yog lwm txoj hauv kev zoo rau kev tswj hwm thiab lub neej zoo.
4. Coolant thiab lubrication
Qhov tseem ceeb: Siv lub siab - zoo, dej- cov kua dej ua kua dej ntawm qhov tseeb.
Muaj nuj nqi: Nws yog ib qho tseem ceeb rau cov cua kub dissipation, nti khiav tawm, thiab txo qhov ua tau - nce ntug. Kev ua kom dej nyab yog feem ntau nyiam.
5. Workpiece Npaj & Clamping
Tshem tawm cov nplais lossis decarburized nto txheej ntawm lub phaj (feem ntau tam sim no raws li - khoom xa tuaj) ua ntej machining, vim nws yog abrasive thiab tuaj yeem ua rau cov cuab yeej siv ntxov ntxov.
Kev ruaj ntseg clamping yog qhov tseem ceeb heev kom tiv taus siab txiav quab yuam yam tsis muaj kev vibration.
