Pib siv tshuab, nyob twj ywm, thiab tsuas yog nqa cov kua yog tias cov khoom siv thiab daim ntawv cog lus tuaj yeem ua tau.
Dab tsi "Dirty" Tiag tiag
Chaw thau khoom: packed swarf, resin, los yog xim sau cov kwj ntawm cov nplej.
Glazing: qhov chaw tig ci ntsa iab thiab slick; nws swb es tsis txhob txiav.
Embedded Smears: mos hlau los yog yas welded rau grit los ntawm tshav kub.
Cov teeb meem no ua rau abrasives txiav kub thiab qeeb. Feem ntau "nroj tsuag" abrasives yeej tsuas yog loaded.
Paub Koj Abrasive Ua ntej koj ntxuav
Coated Abrasives: paper/cloth/film-paper sandpaper, siv, thiab discs. Zoo heev rau ntoo, yas, thiab hlau mos. Backings tsis nyiam soaking.
Bonded Abrasives: vitrified los yog resin log thiab pob zeb. Ntxuav los ntawm kev hnav khaub ncaws kom nthuav tawm cov npoo tshiab.
Superabrasives: pob zeb diamond thiab CBN log. Xav tau lub teeb, kev hnav khaub ncaws tshwj xeeb kom tshem tawm daim ntawv cog lus, tsis txhob zom cov pob zeb diamond.
Khoom tseem ceeb heev:
Ntoo nrog suab (pine, cedar) thauj ceev.
Cov hlau mos (aluminium, tooj dag) smear.
Plastics yaj thaum tshav kub kub thiab smear yooj yim.
Hardened steel loads tsawg tab sis tuaj yeem hlawv yog tias glazed.
Cov ntsiab cai tseem ceeb uas tswj txhua txoj hauv kev
Qhuav ua ntej, ntub kawg: sim kho tshuab ua ntej cov kuab tshuaj los yog dej.
Match Hardness: Lub tshuab ntxhua khaub ncaws yuav tsum softer dua li cov abrasive tab sis ruaj txaus nqa cov residue.
Tswj cua sov thiab ceev: siab RPM ci resin thiab yas rau hauv grit.
Tsiv mus, Tsis txhob nyob: luv, txawm hla; tsis muaj grooving los yog stalling.
Nres Thaum Cov Qauv Tsis Txaus: frayed backing, ploj lawm grit Islands, los yog tawg txhais tau tias hloov.
Field-Tested Methods los ntawm Abrasive Type
Sanding Belts thiab Discs:
Siv lub crepe/rubber tu stick tiv thaiv txoj siv tawv/disc. Lub teeb siab, luv dhau. Qhov no lifts resin thiab plua plav tsis muaj tearing grit.
Tsis stick? Lub crepe huv si- cov khau khau pob taws lossis cov roj hmab ntuj ua haujlwm hauv ib lub pinch.
Tsis txhob txhuam cov hlau; lawv shear grit thiab polish lub nto du.
Daim Ntawv Sandpaper:
Coj mus rhaub daim ntawv rau ntawm ntug ruaj khov kom tshem cov plua plav.
Txhuam nrog tawv nylon. Compressed cua ntawm lub kaum sab xis nyob rau hauv luv luv bursts pab.
Rau lub suab tawv tawv, rub nrog crepe block maj mam. Tsis txhob ntub cov ntawv thaub qab.
Sib tsoo log (Aluminium Oxide, Silicon Carbide; Vitrified / Resin):
Hnav khaub ncaws nrog lub hnub qub- lub log hnav khaub ncaws lossis hnav khaub ncaws. Lub teeb, ruaj khov traverse hla lub ntsej muag.
Re- muaj tseeb lub log thiab qhib cov qauv; tsis txhob carve grooves.
Nco ntsoov lub nplhaib- kuaj lub log ua ntej siv; ceev ceev; hnav khaub ncaws qhuav nrog lub teeb txias tsuas yog pom zoo los ntawm tus tsim lub log.
Pob zeb diamond thiab CBN Log:
Siv ib qho txhuas oxide lossis silicon carbide hnav khaub ncaws nrog lub teeb siab heev.
Koj lub hom phiaj: dislodge loading nyob rau hauv daim ntawv cog lus, tsis txiav lub pob zeb diamond. Coolant yog tias daim ntawv cog lus tso cai.
Pob zeb dej thiab roj pob zeb:
Lp rau ntawm lub phaj flattening los yog 220-400 grit ntub / qhuav ntawm iav nrog dej.
Rau cov pob zeb roj, degrease nrog cov ntxhia dab, txhuam, ces rov- roj me ntsis.
Thaum Yuav Siv Liquid (Ua zoo)
Pitch / Resin los ntawm Ntoo: citrus-raws li cov tshuaj ntxuav tes los yog cov dej ntxhia ntawm txoj siv tawv / discs nrog cov nraub qaum ntev; so, tsis txhob so.
Hlau Smears ntawm Log/Plates: kerosene los yog nplooj siab degreaser, siv sparingly, ces qhuav kom huv si.
Cov yas: zam cov kuab tshuaj hnyav; qis dua thiab kev tu txhua yam muaj kev nyab xeeb dua.
Qhuav Txhua Yam Tag Nrho: noo noo ua rau cov ntaub ntawv rov qab tsis muaj zog, thiab cov kuab tshuaj ntim tau tuaj yeem ua rau cov ntawv cog lus muag.
Kev Nyab Xeeb Uas Txuag Koj Lub Sijhawm
Qhov muag thiab lub ntsws tiv thaiv: Cov hmoov av zoo yoov thaum ntxuav.
Cov cuab yeej tswj: tiv thaiv, ruaj khov, tsis muaj lub tes tsho xoob ze ntawm txoj siv tawv / discs.
Log Integrity: nplhaib- kuaj, sib npaug, thiab nres yog tias kev vibration loj tuaj.
Qhov cua los yog plua plav Extraction: Tsawg plua plav txhais tau tias tsis thauj khoom tom qab.
Pros and Cons of Common Cleaning Approaches
Crepe / Rubber Belt Cleaners:
Pros: ceev ceev, pheej yig, khaws cia grit, ua haujlwm ntawm txoj siv tawv / discs / ntawv.
Cons: tsis zoo rau hnyav hlau smears; tuaj yeem overheat yog tias nias nyuaj dhau.
Nylon Txhuam thiab Compressed Cua:
Pros: maj mam, dav muaj, tsis tshua muaj kev pheej hmoo rau grit.
