Kukhazikika kwa mbale ya lapping kumatha kukonzedwa kokha ndi magiya ochepetsera, kuchuluka kwake kumayendetsedwa ndi chiwonetsero chazithunzi. okonzeka ndi pafupipafupi kutembenuka galimoto, makina chida kuyamba ndi kuyimitsa ndi okhazikika, ndi abwino lapping liwiro akhoza kusankhidwa. Kapangidwe ka makina awiri pamwamba lapping ndi awiri lapping mbale, zonyamulira, anayi Motors, dzuwa gudumu, yokonza zida, etc. Poyerekeza, kapangidwe ka single pamwamba lapping makina ndi zovuta kwambiri, koma dzuwa la pawiri pamwamba lapping. makina ali pawiri pa lapper imodzi pamwamba, ngati workpiece ayenera opukutidwa mbali zonse Mfundo ntchito ya awiri / limodzi pamwamba makina lapping makina: chapamwamba ndi m'munsi mbale lapping atembenuza mbali zosiyana, ndipo workpiece amasunga kusintha ndi kasinthasintha mu chonyamulira. Kukaniza kupukuta kumakhala kochepa ndipo sikuwononga chogwiritsira ntchito, ndipo kugwira ntchito bwino kumakhala kwakukulu chifukwa cha yunifolomu yozungulira mbali zonse. Komanso, Pali grating makulidwe kulamulira dongosolo, ndi makulidwe kulolerana wa workpiece kukonzedwa akhoza kulamulidwa. Makina opukutira apawiri omwe amakhala ndi zida zomatira / zophatikizika zomangira zimagwiritsidwa ntchito popukutira mbali ziwiri za workpiece ndipo nthawi yomweyo amatha kupukutira ndikupukuta mbali ziwiri za workpiece; tiyeni tiwone njira yopangira makina opangira pawiri: 1. Kupukuta kowuma: zowonjezera zowonjezera zowonjezera zimagwiritsidwa ntchito pamwamba pa chida chopukutira panthawi yokonza. Tinthu tating'onoting'ono ta mchenga timakhazikika pa chida panthawiyi, ndipo ntchito yake imakhala yopukutira. Kuchita bwino kwa njira iyi sikwapamwamba, koma kumatha kukwaniritsa kulondola kodabwitsa komanso kamtengo kakang'ono pamwamba (Ra0.02 ~ 0.01μm). 2. Kuthira konyowa: Pakumanga, phala lapang'onopang'ono limagwiritsidwa ntchito pa chida chopukutira, ndipo chomwaza chomwazikana chimagwiritsidwa ntchito popaka. pambali pa abrasive, pali palafini, injini mafuta, oleic asidi, asidi stearic ndi zinthu zina mu lapping phala. Panthawi yopukutira, pali zonyezimira pakati pa mbale ndi chogwirira ntchito, monga momwe tawonetsera pa Chithunzi 8-12b. mu mtundu uwu wa lapping, ndi abrasive makamaka anagubuduza akupera, ndi dzuwa ndi mkulu. Kukula kwapang'onopang'ono ndi Ra0.04 ~ 0.02μm, nthawi zambiri amagwiritsidwa ntchito pokonza movutikira, ndipo pamwamba pake pamakhala imvi. 3. Kupera kofewa: Pakumanga phala, phala lomwe limagwiritsa ntchito chromium oxide monga abrasive limakutidwa pa lapping plate. Popeza abrasive ndi yofewa kuposa lapping mbale ndi workpiece, abrasive imayimitsidwa pakati workpiece ndi mbale lapping pa ndondomeko lapping. Kugwirizana kwa mankhwala pakati pa abrasive ndi pamwamba pa workpiece kumatulutsa filimu yofewa kwambiri ya okusayidi, ndipo filimuyo pamatope imawonongeka mosavuta ndi abrasive.
