Dab tsi yog cov cuab yeej txiav feem ntau siv rau kev ua hlau cam khwb cia?
1, Hom thiab ua cov yam ntxwv ntawm cam khwb cia hlau
Cam khwb cia hlau tuaj yeem muab faib ua:; Grey cam khwb cia hlau, dawb cam khwb cia hlau, malleable cam khwb cia hlau, ductile hlau, ductile hlau, alloy cam khwb cia hlau, thiab hais txog. Grey cam khwb cia hlau yog dav siv nyob rau hauv kev lag luam automotive, uas kuj yog ib qho kev thov loj rau CNC txiav cov cuab yeej, yog li cov chaw ua haujlwm feem ntau muaj kev thov rau grey cam khwb cia hlau ua.
2, Dab tsi txiav cov cuab yeej siv rau kev ua cov hlau cam khwb cia zoo tib yam
Feem ntau cov cam khwb cia hlau raug xa mus rau hauv tsab xov xwm no yog grey cam khwb cia hlau, hlau hlau, thiab austenitic cam khwb cia hlau. Grey cam khwb cia hlau muaj kev ua tau zoo, xws li nyuaj alloy milling cutters coated nrog txhuas oxide, uas feem ntau muaj peev xwm txiav grey cam khwb cia hlau. Vim muaj kev cuam tshuam ntawm graphite cov ntsiab lus ntawm kev ua haujlwm ntawm cov khoom siv hlau, feem ntau siv tau cov khoom siv nyuaj alloy pas nrig kev lag luam coated alloy milling cutters.
Ordinary cam khwb cia hlau ua cov cuab yeej thiab kev lag luam tungsten steel milling cutters tuaj yeem tuav nws. Thib ob, cobalt uas muaj cov cuab yeej siv high-speed steel tuaj yeem siv tau.
3, Dab tsi txiav cov cuab yeej siv rau qhov nyuaj rau tshuab cam khwb cia hlau
Txog tam sim no, peb tsuas yog muab piv txwv ntawm cov hlau cam khwb cia txias. Txias nyuaj cam khwb cia hlau yog ib hom hnav-resistant cam khwb cia hlau, uas yog tsim los ntawm accelerating qhov txias ntawm lub saum npoo ntawm cov cam khwb cia hlau thaum lub sij hawm casting, tso cai rau kom tau ib tug zoo cam khwb cia hlau qauv nyob rau saum npoo, ua rau siab hardness thiab hnav. tsis kam. Cold hard cam khwb cia hlau tuaj yeem muab faib ua cov hlau cam khwb cia txias, npib tsib xee chromium txias cam khwb cia hlau, siab chromium dawb cam khwb cia hlau, thiab chromium vanadium dawb cam khwb cia hlau.
1) Cov yam ntxwv ua haujlwm ntawm cov hlau cam khwb cia txias
Txias nyuaj cam khwb cia hlau muaj siab hardness, zoo brittleness, thiab ib tug loj chav tsev txiav quab yuam. Ntxiv mus, nws cov chips yog nyob rau hauv ib tug fragmented zoo, thiab txiav quab yuam thiab txiav kub yog concentrated nyob ze ntawm lub txiav vim hais tias ntawm luv luv kev sib cuag ntawm lub cuab tam thiab txiav, uas yooj yim ua rau cov cuab yeej hnav thiab puas. Cov txheej txheem txheej txheem ntawm cov hlau cam khwb cia txias feem ntau yog khoob, nrog cov nyiaj loj thiab tsis sib xws, uas ua rau muaj qhov nyuaj ntawm kev ua cov hlau cam khwb cia. Tau kawg, tam sim no muaj cov kev daws teeb meem zoo rau cam khwb cia hlau machining cov cuab yeej, cam khwb cia hlau milling cutters, thiab lwm yam.
2) Kev xaiv cov cuab yeej txiav rau Cold Hardened Cast Iron Processing
Nws yog qhov zoo tshaj plaws los xaiv cov cuab yeej cuab tam nrog cov hardness siab, hnav tsis kam, thiab qee lub zog thaum ua cov hlau cam khwb cia txias. Feem ntau, YG hom tawv alloy lossis alumina ceramic txiav cov cuab yeej nrog coated nplua lossis ultra-nplua nplej yog siv.
3) Kev txiav tsis ua haujlwm rau kev ua haujlwm txias cam khwb cia hlau milling cutters
Hard alloy tej cuab yeej; Tsawg ceev loj pub. V{{0}}kwv yees li 9m/min, thiab tus nqi pub yog feem ntau xaiv raws li lub ntsiab sib txawv lub kaum sab xis thiab rov qab txiav nyiaj. Rau kev ua haujlwm ntxhib ntawm cov cam khwb cia hlau, xaiv 0.5mm/r, thiab rau kev ua haujlwm zoo ntawm cam khwb cia hlau, xaiv 0.1-0.4mm/r.
Ceramic tej cuab yeej; Feem ntau, kev kub ceev milling raug xaiv, nrog ntxhib thiab semi precision machining ntawm cam khwb cia hlau V=50-80m/min, thiab precision machining V=80-120m/min.
Cam khwb cia hlau ua cov cuab yeej, xws li txiav hais, yuav siv tau rau ntxhib, semi precision, thiab precision machining. Yog hais tias koj tseem tsis paub dab tsi milling cutter siv rau cam khwb cia hlau, ntawm chav kawm, YG hom hard alloy tej cuab yeej yuav tsum tau xaiv rau kev ua cam khwb cia hlau milling cutters.
