Dab tsi yog qhov milling cutter siv rau? Hnav ntawm milling cutter thaum siv
Thaum lub sij hawm milling txheej txheem, milling cutter nws tus kheej yuav hnav thiab npub thaum txiav chips. Tom qab lub milling cutter yog blunt rau qee qhov, yog tias nws tseem siv tau, nws yuav ua rau muaj kev nce ntxiv hauv milling quab yuam thiab txiav qhov kub thiab txias, thiab tus nqi ntawm cov milling cutter tseem yuav nce sai, yog li cuam tshuam rau kev ua haujlwm. Qhov tseeb thiab qhov zoo ntawm qhov chaw thiab kev siv tus nqi ntawm cov milling cutter.
Qhov chaw ntawm cov cuab yeej hnav tshwm sim feem ntau nyob rau pem hauv ntej thiab nraub qaum ntawm qhov txiav ntug thiab nws qhov chaw nyob ib puag ncig. Kev hnav ntawm milling cutter feem ntau yog hnav ntawm lub nraub qaum thiab ntug ntawm cov hniav.
1. Ua rau milling cutter hnav
Lub ntsiab yog vim li cas rau milling cutter hnav yog txhua yam hnav thiab thermal hnav.
1. Mechanical wear: Mechanical wear tseem hu ua abrasive wear. Vim yog cov ntsiab lus nyuaj me me ntawm qhov sib txhuam ntawm cov chips lossis cov khoom ua haujlwm, xws li carbides, oxides, nitrides thiab cov npoo ua ke, cov cim ntawm qhov sib txawv ntawm qhov tob yog carved ntawm lub cuab yeej, ua rau cov khoom siv. Qhov nyuaj ntawm cov khoom siv ua haujlwm, ntau dua qhov muaj peev xwm ntawm cov khoom tawv tawv kom khawb qhov saum npoo ntawm lub cuab yeej. Hom kev hnav no tau pom tseeb cuam tshuam rau cov cuab yeej siv siab ceev steel. Txhim kho qhov kev sib tsoo zoo ntawm lub tshuab txiav milling thiab txo qhov roughness ntawm tus nqi ntawm lub hauv ntej, nram qab thiab txiav npoo, uas tuaj yeem ua kom qeeb ntawm cov khoom siv ntawm lub tshuab txiav.
2. Thermal hnav: Thaum lub sij hawm milling, qhov kub nce siab vim yog lub cim ntawm kev txiav cov cua sov. Lub hardness ntawm cov cuab yeej siv yog txo vim lub sij hawm hloov pauv los ntawm qhov kub thiab txias, thiab cov khoom siv yog adhered rau lub nti thiab lub workpiece thiab raug tshem tawm los ntawm adhesion, uas ua rau kev sib khi hnav; nyob rau hauv qhov kev txiav txim ntawm qhov kub thiab txias, cov ntsiab lus alloy ntawm cov khoom siv thiab cov khoom siv ua haujlwm sib txawv thiab hloov ib leeg. , cov khoom siv kho tshuab ntawm cov cuab yeej raug txo, thiab diffusion hnav tshwm sim nyob rau hauv qhov kev txiav txim ntawm kev sib txhuam. Cov hnav ntawm milling cutters tshwm sim los ntawm kev txiav cov cua sov thiab qhov kub thiab txias yog sib sau ua ke hu ua thermal hnav.
Thib ob, kev hnav cov txheej txheem ntawm milling cutter
Ib yam li lwm cov cuab yeej txiav, hnav cov milling cutters maj mam txhim kho nrog lub sijhawm txiav. Cov txheej txheem hnav tuaj yeem muab faib ua peb theem:
1. Thawj theem hnav: Cov theem no hnav sai sai, feem ntau yog vim cov pob txha pob txha uas tsim los ntawm cov khoom sib tsoo ntawm qhov chaw sib tsoo thiab cov burrs ntawm cov hniav yog sai sai hauv av nyob rau lub sij hawm luv luv tom qab lub milling cutter yog sharpened. Yog tias qhov burr loj heev, qhov hnav yuav loj heev. Txhim kho qhov zoo ntawm lub tshuab txiav milling, thiab siv kev sib tsoo los yog whetstone polishing txiav ntug thiab pem hauv ntej thiab nram qab, uas tuaj yeem txo qhov hnav ntawm thawj theem.
2. Ib txwm hnav theem: Nyob rau theem no, qhov hnav kuj qeeb, thiab tus nqi hnav nce tusyees thiab stably nrog lub sijhawm txiav.
3. Kev hnav sai sai: Tom qab siv lub tshuab txiav milling rau lub sijhawm ntev, cov hniav yuav blunt, lub zog milling nce, txiav qhov kub thiab txias, cov milling tej yam kev mob yuav tsis zoo, milling cutter hnav tus nqi nce sharply, tus nqi hnav nce. sharply, thiab lub cuab tam sai poob ntawm tej peev xwm. Thaum siv lub tshuab txiav milling, nws yuav tsum zam kom lub milling cutter hnav mus rau theem no.
3. Cov txheej txheem dullness ntawm milling cutter
Hauv kev ua haujlwm tiag tiag, yog tias lub tshuab txiav milling muaj ib qho ntawm cov xwm txheej hauv qab no, nws txhais tau hais tias lub milling cutter yog blunt: qhov roughness tus nqi ntawm lub tshuab nto yog qhov loj dua qhov qub, thiab cov pob qij txha thiab cov nplais tshwm rau ntawm qhov chaw; qhov txiav kub yog nce ntxiv, thiab cov chips Cov xim hloov; qhov txiav quab yuam nce, thiab txawm tias kev vibration tshwm sim; lub nraub qaum nyob ze ntawm ntug txiav yog pom tseeb hnav, thiab txawm tias lub suab txawv txav tshwm sim. Lub sijhawm no, lub milling cutter yuav tsum tau muab tshem tawm kom zoo dua qub, thiab milling tsis tuaj yeem txuas ntxiv mus, kom tsis txhob hnav hnyav lossis txawm tias puas tsuaj rau lub tshuab txiav.
