Pwm polishing ntsig txog kev paub cov ntsiab lus

Polishing nyob rau hauv pwm ua yog txawv heev los ntawm polishing nto yuav tsum tau nyob rau hauv lwm yam lag luam. Nto polishing feem ntau tsuas yog yuav tsum tau txais lub ntsej muag ci, thaum pwm polishing, nruj me ntsis hais lus, yuav tsum hu ua daim iav ua. Tsis tsuas yog polishing nws tus kheej muaj cov kev xav tau siab, tab sis nws kuj muaj cov qauv siab rau qhov chaw flatness, smoothness, thiab geometric raug.

Cov txheej txheem tshwj xeeb ntawm daim iav polishing ntawm pwm

Cov txheej txheem ntawm pwm daim iav polishing yog tsuas yog los txo qhov roughness ntawm workpiece nto. Txawv pwm polishing phiaj yog muab rau txawv pwm polishing. Muaj ntau ntau txoj hauv kev rau pwm polishing:

(1) Mechanical polishing. Txoj kev no tsuas yog tso siab rau kev txiav lossis yas deformation ntawm cov khoom nto kom tshem tawm cov convex ntawm qhov chaw kom tau txais qhov chaw du. Cov cuab yeej xws li oilstone strips, wool wheels, thiab sandpaper feem ntau yog siv, thiab phau ntawv ua haujlwm yog txoj hauv kev tseem ceeb. Rau cov pwm uas muaj qhov zoo dua qhov yuav tsum tau ua, cov txheej txheem ultra-precision polishing tuaj yeem siv. Txoj kev no tuaj yeem siv cov cuab yeej tshwj xeeb abrasive thiab polishing kua uas muaj cov abrasives kom ua tiav qhov roughness siab heev.

(2) Tshuaj polishing. Tshuaj polishing yuav tsum muab cov pwm tso rau hauv cov tshuaj nruab nrab, siv cov tshuaj ua haujlwm kom nyiam ua kom cov pob zeb tawg rau ntawm qhov chaw, ua rau lub ntsej muag du. Txoj kev no tsis tas yuav tsum muaj cov cuab yeej siv, tuaj yeem polish workpieces nrog cov duab nyuaj, thiab ua ntau yam haujlwm tib lub sijhawm, tab sis qhov roughness feem ntau tuaj yeem ncav cuag li 10 μm.

(3) Electrolytic polishing. Lub hauv paus ntsiab lus ntawm electropolishing yog zoo ib yam li tshuaj polishing, polishing nto los ntawm kev xaiv dissolving me me protrusions rau saum npoo ntawm pwm. Txoj kev no tuaj yeem tshem tawm cov tshuaj tiv thaiv cathode thiab tau txais cov nyhuv polishing zoo dua.

(4) Ultrasonic polishing. Lub workpiece yog muab tso rau hauv lub abrasive ncua kev kawm ntawv thiab muab tso rau hauv lub ultrasonic teb, thiab oscillation ntawm ultrasonic tsis yog siv los zom thiab polish lub nto ntawm workpiece. Txoj kev no muaj me me macroscopic quab yuam thiab yuav tsis ua rau deformation ntawm lub workpiece, tab sis kev tsim khoom thiab kev teeb tsa ntawm cov cuab yeej nyuaj dua.

(5) Cov kua dej polishing. Txoj kev no tso siab rau cov kua dej ceev ceev thiab cov khoom abrasive nws nqa los ntxuav tawm ntawm qhov chaw ua haujlwm kom ua tiav cov nyhuv polishing. Xws li abrasive dav hlau machining, kua dav hlau machining, kua fais fab sib tsoo, thiab lwm yam.

(6) Sib nqus sib tsoo thiab polishing. Sib nqus abrasives yog siv los tsim cov txhuam txhuam hauv qab qhov kev ua ntawm cov hlau nplaum kom zom cov khoom ua haujlwm.

Txhua txoj hauv kev no muaj nws tus yam ntxwv thiab tsim nyog rau ntau hom pwm thiab qhov sib txawv ntawm qhov zoo. Txoj kev xaiv twg yog nyob ntawm yam xws li cov txheej txheem tshwj xeeb, cov khoom siv, thiab kev lag luam. Feem ntau, feem ntau cov pwm polishing txoj kev yog thawj peb txoj kev.

Cov txiaj ntsig ntawm pwm polishing

(1) Tom qab polishing, cov pwm kab noj hniav yuav smoother, ua kom yooj yim rau demould thaum lub sij hawm tsim khoom, txhim kho kev tsim khoom, txo cov voj voog ntau lawm, thiab ua tiav cov nqi txo.

(2) Cov pwm polished muaj qis roughness, siab dua flatness thiab smoothness, yog li cov khoom tsim muaj ib tug ntau majestic thiab zoo nkauj tsos, yog ntau txaus, thiab tau yooj yim qhib lub lag luam.

(3) Kuv ntseeg tias ntau tus neeg paub tias nws kim npaum li cas los qhib cov pwm pwm, yog li tom qab ntau cov pwm polished, cov neeg siv khoom yuav ua electroplating. Tom qab electroplating, cov pwm yog hnav-resistant thiab corrosion-resistant, uas zoo heev rau kev siv cov pwm. lub neej.

(4) Tom qab pwm polishing, qhov tseeb ntawm cov pwm sib txuam saum npoo tuaj yeem txhim kho kom tsis txhob muaj burrs los ntawm kev cuam tshuam rau kev tsim khoom.

Cov txheej txheem yooj yim rau kev tuav polishing

Txhawm rau kom tau txais cov txiaj ntsig zoo polishing, nws yog ib qho tseem ceeb uas yuav tsum muaj cov cuab yeej polishing zoo thiab cov khoom siv, xws li oilstones, sandpaper, pob zeb diamond abrasive muab tshuaj txhuam, thiab lwm yam, thiab tom qab ntawd ua phau ntawv (tes) polishing. Kuj tseem muaj qhov chaw ua haujlwm polishing uas yuav tsum muaj kev cob qhia tsis muaj plua plav. Kev xaiv ntawm txoj kev polishing nyob ntawm qhov chaw tom qab ua ntej, xws li machining, hluav taws xob tawm machining, sib tsoo, thiab lwm yam.

Cov teeb meem dab tsi yuav tsum tau them sai sai rau thaum tuav polishing?

Tsis txhob ua kom puas cov qauv ntawm lub workpiece; tsis txhob ua puas lub kaum sab xis ntawm lub workpiece, thiab tsis txhob ua puas lub rationality ntawm lub kaum sab xis; xyuam xim rau qhov kev txiav txim ntawm kev siv cov cuab yeej polishing; xyuam xim rau qhov siv ntawm polishing.

Thaum sanding nrog sandpaper, koj yuav tsum xyuam xim rau cov ntsiab lus hauv qab no:

(1) Siv cork los yog xyoob sticks thiab xuab zeb lawv nrog sandpaper. Thaum polishing ib puag ncig lossis spherical nto, siv lub cork tuaj yeem ua kom zoo dua qhov curvature ntawm puag ncig thiab kheej kheej. Cov ntoo tawv, xws li cherry, zoo dua rau polished tiaj tus. Txiav qhov kawg ntawm cov ntoo strips kom lawv ua raws li cov duab ntawm cov hlau qhov chaw kom tiv thaiv cov kaum ntse ntse ntawm cov ntoo strips (los yog xyoob strips) los ntawm kev sib cuag ntawm qhov chaw ntawm cov hlau thiab ua rau khawb tob.

(2) Thaum siv cov ntawv xuab zeb sib txawv, cov kev sib tsoo yuav tsum hloov ntawm 45 ° thiab 90 °, thiab cov kab txaij thiab cov duab ntxoov ntxoo sab laug los ntawm cov ntawv xuab zeb yav dhau los yuav tsum txawv. Ua ntej hloov mus rau lwm hom ntawv xuab zeb, polishing nto yuav tsum tau ua tib zoo wiped nrog ntxuav cov kua, vim me me gravel seem nyob rau saum npoo yuav cuam tshuam tag nrho cov txheej txheem polishing. Cov txheej txheem ntxuav no kuj tseem ceeb thaum hloov ntawm cov ntawv xuab zeb polishing rau pob zeb diamond abrasive paste polishing. Tag nrho cov hais thiab kerosene yuav tsum tau muab tshem tawm ua ntej polishing ntxiv.

(3) Txhawm rau kom tsis txhob khawb thiab hlawv ntawm qhov chaw ua haujlwm, yuav tsum tau saib xyuas tshwj xeeb thaum xuab zeb nrog # 1200 thiab # 1500 daim ntawv xuab zeb. Yog li thauj khoom me me thiab siv ob-kauj ruam polishing txoj kev los txhuam qhov saum npoo. Thaum xuab zeb nrog txhua hom ntawv xuab zeb, koj yuav tsum xuab zeb ob zaug hauv ob txoj kev sib txawv, tig 45-90 degrees ntawm ob qho kev qhia txhua zaus.
