Polishing yog txheej txheem uas txhua qhov impurities thiab irregularities raug tshem tawm ntawm qhov chaw ntawm cov hlau thiab nws rov ua nws cov lus qub qub.

Txoj Kev Ua Haujlwm

Tam sim no, muaj ntau hom kev sib tsoo ntawm cov hlau nto:

  • thawj thiab feem ntau yooj yim thiab ntau txoj kev yog tes polishing. Feem ntau, txoj kev no yog siv thaum ua haujlwm kho ntawm qhov chaw.
  • Txoj kev tom ntej no yog kev tshaj lij thiab hu ua semi-mechanical sib tsoo. Txoj kev no yog ua los ntawm kev siv lub tshuab polishing, uas tshwj xeeb polishing log tau muab tso rau.
  • Txoj kev thib peb yog tshuab. Nws yog siv hauv kev lag luam loj loj. Txhua qhov kev sib tsoo rau cov khoom siv hlau yog ua los ntawm cov tshuab hauv hom tsis siv neeg.
  • hom kawg yog waterjet sib tsoo, nqa tawm ntawm cov tshuab tshwj xeeb. Txoj kev no tsuas yog siv yog tias qhov ntim ntawm cov khoom hlau uas yuav tsum tau ua tiav yog qhov loj heev. Nws yuav tsum tau ntxiv cov ntshav plasma, nrog rau cov tshuaj-mechanical uaua raws li tib txoj cai.

Cov cuab yeej thiab txoj kev polishing

Cov txheej txheem polishing yog ib qho kev txiav txim uas yuav tsum muaj qee yam cuab yeej. Ntxiv mus, nyob ntawm tus txheej txheem ntawm kev ua haujlwm no, cov khoom muag siv kuj hloov pauv. Cov cuab yeej siv feem ntau yog:

  • tshuab polishing;
  • sib;
  • hluav taws xob ntse;
  • drills nrog latch.

Nws yog ib qho tsim nyog hais txog cov txheej txheem ntawm kev kho deg, vim nws muaj ntau qhov zoo. Thawj qhov tseem ceeb tshaj plaws yog qhov muaj peev xwm tswj tau qhov ceev ntawm lub tshuab lub voj voog. Qhov no muaj txiaj ntsig zoo rau tag nrho cov txheej txheem kev kho hlau saum npoo. Polishing yog cov txheej txheem ilv heev, thiab yog li ntawd, piv txwv li, polishing tshuab tuaj yeem nruab nrog ntau hom nozzles. Cov khoom siv los ntawm cov ntsiab lus ntxiv no tuaj yeem yog ntaub plaub, tawv, ntaub.

Txoj kev ua tshwj xeeb

Nto polishing tuaj yeem ua tiav los ntawm kev sib xyaw ua ke. Kev sib xyaw ua ke ntawm ntau txoj kev ua haujlwm feem ntau yuav tsum tau ua thaum cov hlau nto tsis tau npaj rau kev ua haujlwm, thiab tseem muaj qhov muaj qhov ntxhib ntawm qhov chaw. Nrog rau cov kev tsis txaus no, feem ntau, ua ntej pib nrog polishing nws tus kheej, kev npaj electrolytic-plasma ntev yog nqa tawm. Thaum lub sij hawm no, cov hlau loj heev raug tshem tawm.

Nws yog ib qho tsim nyog sau cia tias txoj kev tshwj xeeb ntawm kev ua cov khoom siv no yog siv rau hauv cov xwm txheej hnyav tshaj plaws, thaum nws tsim nyog los kho cov luster ntawm cov hlau txheej hauv lub sijhawm luv luv. Qhov tsis zoo ntawm cov txheej txheem kev ua haujlwm tshwj xeeb no suav nrog qhov tseeb tias cov nqi hluav taws xob ntawm thawj theem yog 100% siab dua thaum ua los ntawm lwm txoj kev. Nws tuaj yeem ntxiv tau tias polishing tshwm sim nyob rau hauv ob theem: thawj zaug, qhov saum npoo yog degreased, tab sis qhov thib ob, kev sib tsoo nws tus kheej pib.

Tes polished

Hnub no, muaj ntau yam khoom siv polishing uas yuav pab kho qhov qub luster ntawm cov hlau nto yam tsis tas siv cov tshuab tshwj xeeb. Muaj peb pawg ntawm cov khoom no.

Thawj suav nrog dej tshuaj. Cov tshuaj no tsis muaj cov rog hauv lawv cov muaj pes tsawg leeg, tab sis tib lub sijhawm lawv muaj peev xwm ua kom huv si ntawm cov hlau los ntawm kev sib kis.

Pab pawg thib ob yog cov tshuaj organic. Cov muaj pes tsawg leeg ntawm cov pastes no suav nrog paraffin, nrog rau ntau cov roj sib txawv. Tsis tas li ntawd, cov khoom zoo li no tau diluted nrog lwm hom roj lossis fatty acids ua ntej siv.

Pab pawg thib peb yog pob zeb diamond pastes, uas suav tias yog kev hloov pauv hloov pauv tam sim no. Cov khoom lag luam los ntawm pawg no muaj peev xwm sai thiab zoo ntxuav txhua qhov chaw hlau los ntawm kev sib kis.

Polishing nrog pob zeb diamond muab tshuaj txhuam

Pob zeb diamond muab tshuaj txhuam zoo heev, piv txwv li, rau polishing tsheb. Rauua tiav cov haujlwm tiav, koj yuav tsum muaj lappings thiab ob peb lub raj ntawm muab tshuaj txhuam. Txhawm rau pib ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau muab tshuaj txhuam rau hauv ib txheej txawm ntawm ib daim ntaub lossis lwm qhov chaw ua haujlwm ntawm cov khoom uas yuav polished. Thaum lub sij hawm qhov kev ntsuam xyuas, nws tau pom tias kom ua tau zoo dua polishing efficiency nrog pob zeb diamond muab tshuaj txhuam, nws tsim nyog ntxiv txiv roj roj los yog castor roj rau nws. Thaum lub sij hawm tib cov kev ntsuam xyuas, nws tau pom tias qhov zoo tshaj plaws piv ntawm muab tshuaj txhuam thiab roj yuav yog 40 thiab 60%, feem. Tom qab qhov sib tov tau thinned, nws yuav tsum tam sim ntawd siv rau saum npoo kom polished. Cov lus pom zoo los ntawm cov kws tshaj lij qhia tias nws yog qhov zoo tshaj plaws los pib nrog cov nplej loj, thiab maj mam txav mus rau cov khoom siv abrasive.

Sanding lossis polishing?

Tam sim no, thaum tib neeg hais tias "sib tsoo" thiab "polishing", lawv txhais tau tib yam. Txawm li cas los xij, ob txoj haujlwm no muaj lub hom phiaj sib txawv me ntsis, txhais tau tias lawv tsis txhais hais tias tib yam.

Thaum tham txog kev sib tsoo cov hlau, nws txhais tau hais tias qhov kev huv huv ntawm qhov chaw thiab nws qhov ci ntsa iab yuav ua tiav los ntawm kev tshem tawm cov txheej nyias ntawm cov hlau. Rau qhov no, txoj kev sib tsoo ntxhib feem ntau yog siv. Ib lub ntsiab lus raug rau txoj kev tu no yuav huv si tiag tiag, tab sis nws yuav tsis pom qhov kev xav hauv nws, piv txwv li.

Cov txheej txheem polishing tshem tawm tshaj plawsme me nto irregularities, ua rau nws txig du. Nyob rau hauv tus txheej txheem ntawm kev ua hauj lwm zoo li no, ib tug me me ntawm cov hlau raug tshem tawm. Qhov tshwm sim uas zoo polishing yuav muab yuav ci ntsa iab heev uas nws yuav luag tsis tuaj yeem qhia qhov txawv ntawm nws thiab siv lapping.

tshuaj polishing

Kev siv tshuaj polishing ntawm qhov chaw yog ua los ntawm kev txiav txim ntawm cov tshuaj ntawm cov hlau. Nyob ntawd nws yog ua ke nrog galvanic vapors, uas tsim ib tug passivating oxide zaj duab xis nyob rau saum npoo ntawm cov khoom. Raws li qhov tshwm sim ntawm kev siv txoj kev no, koj tuaj yeem tshem tawm qhov me me ntawm microroughnesses ntawm qhov chaw ntawm cov hlau, muab nws ci. Qhov no tshwm sim tib lub sijhawm thaum cov txheej txheem saum toj kawg nkaus dissolves.

Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov ntawm no tias qhov zoo ntawm polishing nrog txoj kev no yog nyob ntawm seb cov zaj duab xis tau tsim sai npaum li cas thiab sai npaum li cas nws yaj hauv dej. Qhov zoo tshaj plaws tshwm sim, piv txwv li qhov zoo tshaj plaws gloss ntawm cov hlau nto, tuaj yeem ua tiav yog tias qhov tsawg kawg nkaus zaj duab xis thickness ncav cuag, thiab qhov no yuav tsum txaus los tiv thaiv etching ntawm cov hlau. Txhawm rau ua tiav qhov txiaj ntsig no, nws yog ib qho tsim nyog yuav tsum sib npaug ntawm tus nqi tsim thiab ntxuav tawm ntawm oxide nto.

Electrochemical method

Electrochemical polishing yog txheej txheem uas txo qhov roughness ntawm cov hlau thiab muab daim iav tiav. Txhawm rau ua kom cov txheej txheem no muaj tseeb,Nws yog ib qho tsim nyog los tso ib feem, uas yog lub anode nyob rau hauv qhov teeb meem no, nyob rau hauv ib da dej nrog ib tug tshuaj hu ua electrolyte. Ib qho anode yog ib qho electrode uas txuas nrog tus ncej zoo ntawm qhov tam sim no. Txij li cov electrode thib ob yuav tsum tau siv rau cov txheej txheem polishing, cathodes ua los ntawm tooj liab yog siv los ua cov khoom siv no.
