Qhov zoo ntawm scraping thiab sib tsoo ntawm lub platform txiav txim siab nws qhov tseeb. Lub npe hu ua "scraping and grinding" yog hais txog kev sib xyaw ua ke ntawm kev sib tsoo thiab kev sib tsoo. Ntawd yog, tiaj tus scraping thiab sib tsoo zaub, ces tiaj scraping thiab sib tsoo zaub, thiab lwm yam, alternating voj voog, ua haujlwm tas li. Thaum lub sij hawm tag nrho cov txheej txheem scraping thiab sib tsoo ntawm cam khwb cia hlau platforms, lawv feem ntau mus txog peb theem: ntxhib scraping, nplua scraping, thiab nplua scraping. Hauv qab no yog cov ncauj lus kom ntxaws qhia txog lub cam khwb cia hlau platform:
1. Scratching: Scratching muaj ob txoj haujlwm: thawj zaug, nws yog qhov zoo nkauj, thiab qhov thib ob, nws muaj cov haujlwm ntawm cov roj lubricating. Cov qauv uas muaj xws li cov qauv kab pheeb ces kaum, nqos cov qauv, thiab cov qauv ntses nplai. Tsis tas li ntawd, qhov degree ntawm hnav tom qab ua haujlwm tiaj tus tuaj yeem txiav txim siab los ntawm kev saib xyuas kev ncaj ncees thiab ploj ntawm tus qauv qub.
2. Rough scraping: Yog hais tias qhov chaw ntawm lub workpiece yog ntxhib, lub machining marks yog sib sib zog nqus, los yog cov nto yog rusted heev, tsis sib xws, los yog twisted, thiab lub scraping nyiaj siab tshaj 0.005mm, ntxhib scraping yuav tsum ua ntej. Cov yam ntxwv ntawm kev ntxhib los mos yog siv cov scraper ntev nrog lub stroke ntev (nruab nrab ntawm 10mm thiab 15mm), cov hniav dav (10mm), thiab cov cim scraper nyob rau tib qho kev taw qhia thiab tsis txhob rov ua dua. Tom qab tshem tawm cov riam los ntawm kev siv tshuab, koj tuaj yeem zom lawv thiab txhuam lawv raws li cov ntsiab lus siab pom. Thaum muaj 4-6 cov ntsiab lus ntawm 25 ㎡ x 25 ㎡ ntawm qhov chaw ua haujlwm thiab muaj cov npoo rau kev nplua nplua, kev nplua nplua tuaj yeem pib.
3. Fine scraping: Fine scraping * yog txheej txheem ntawm scraping tawm cov ntsiab lus siab tom qab ntxhib scraping. Nws cov yam ntxwv yog siv cov txheej txheem luv luv (nrog rau rab riam dav txog 6 hli thiab ntev ntawm 5mm ~ 10mm), uas disperses cov ntsiab lus sib tsoo sai. Thaum zoo scraping, nws yog ib qho tsim nyog yuav tau khawb hauv ib qho kev taw qhia. Tom qab khawb ib zaug, lub mesh yuav tsum tau muab khawb ntawm 45 degree lossis 60 degree lub kaum sab xis thaum khawb ob zaug. Thaum qhov nruab nrab qhov kev tshawb fawb taw tes yog 10-14 cov ntsiab lus ntawm 25 ㎡ x 25 ㎡, kev nplua nplua tuaj yeem xaus.
4. Fine scraping: Fine scraping yog ua los ntawm kev nplua nplua, siv cov scrapers me me lossis precision scrapers nrog arcs. Cov riam cim dav yog li 4 hli, thiab qhov nruab nrab sib tsoo yuav tsum yog 20-25 cov ntsiab lus ntawm 25 ㎡ × 25 ㎡. Cam khwb cia hlau platforms feem ntau yog siv rau scraping soj ntsuam cov cuab yeej, precision guides, thiab ceev cov cuab yeej tiv tauj nto.
