Kodi Mwasankha Pang'onopang'ono Pamakina Oyenera Pamakina Obowola ndi Makina a CNC

Mitundu ya zida zobowola zomwe zingagwiritsidwe ntchitoCNC pobowola ndi makina mpherozikuphatikizapo ma twist drills, U drill, chiwawa, ndi core drills.

Ma twist drill amagwiritsidwa ntchito kwambiri pobowola mutu umodzi kuti kubowola mapanelo osavuta amodzi. Tsopano sawoneka kawirikawiri mwa opanga ma board ozungulira, ndipo kuya kwawo kobowola kumatha kufika nthawi 10 m'mimba mwake mwa kubowola.

Ngati gawo la gawo lapansi silili lalitali, kugwiritsa ntchito manja obowola kungapewe kupotoza kubowola. TheCNC pobowola makinaamagwiritsa ntchito simenti ya carbide yokhazikika ya shank kubowola, yomwe imadziwika ndi kuthekera kosintha m'malo mwake. Mkulu udindo kulondola, palibe chifukwa ntchito kubowola manja manja. Ngodya yayikulu ya helix, kuthamanga kwa chip kuchotsa, yoyenera kudula mwachangu. Mkati mwa utali wonse wa chitoliro cha chip, m'mimba mwake wa kubowola ndi koni yotembenuzidwa, ndipo kukangana ndi khoma la dzenje pobowola kumakhala kochepa, ndipo khalidwe la kubowola ndilokwera kwambiri. Wamba kubowola shank diameters ndi 3.00mm ndi 3.175mm.

Pobowola mapepala a chubu nthawi zambiri amagwiritsa ntchito simenti ya carbide, chifukwa nsalu yagalasi ya epoxy yomwe imakutidwa ndi mbale yamkuwa imavala chidacho mwachangu kwambiri. Chomwe chimatchedwa cemented carbide chimapangidwa ndi tungsten carbide powder monga matrix ndi cobalt ufa monga binder kupyolera mu kupanikizika ndi sintering. Nthawi zambiri imakhala ndi 94% tungsten carbide ndi 6% cobalt. Chifukwa cha kuuma kwake kwakukulu, ndizovuta kwambiri kuvala, zimakhala ndi mphamvu zinazake, ndipo ndizoyenera kudula mothamanga kwambiri.

Kusalimba kolimba komanso kuphulika kwambiri. Pofuna kukonza magwiridwe antchito a simenti ya carbide, ena amagwiritsa ntchito wosanjikiza wa 5-7 microns wa extra-hard titanium carbide (TIC) kapena titanium nitride (TIN) pagawo la carbide pogwiritsa ntchito nthunzi wamankhwala kuti likhale ndi kulimba Kwambiri. Ena amagwiritsa ntchito ukadaulo wa ion implantation kuyika titaniyamu, nayitrogeni, ndi kaboni mu matrix kukuya kwina kwake, zomwe sizimangowonjezera kulimba ndi mphamvu, komanso zigawo zobzalidwazi zimatha kusamukira mkati pomwe chobowolacho chabwerera. Ena amagwiritsa ntchito njira zakuthupi kuti apange filimu ya diamondi pamwamba pakubowola pang'ono, zomwe zimathandizira kwambiri kuuma komanso kuvala kukana kwa kubowola. Kuuma ndi mphamvu ya simenti ya carbide sikungokhudzana ndi chiŵerengero cha tungsten carbide ndi cobalt, komanso ndi tinthu tating'ono ta ufa.

Pa tinthu tating'onoting'ono tomwe timabowola cemented carbide, makulidwe ake amtundu wa tungsten carbide ndi pansi pa 1 micron. Kubowola kotereku sikumangokhala kuuma kwakukulu komanso kumapangitsanso kulimba mtima komanso kusinthasintha. Pofuna kupulumutsa ndalama, mabowo ambiri tsopano amagwiritsa ntchito shank yowotcherera. Kubowola koyambirira kumapangidwa ndi aloyi yolimba yonse. Tsopano shank yobowola kumbuyo imapangidwa ndi chitsulo chosapanga dzimbiri, chomwe chimachepetsa kwambiri mtengo. Komabe, chifukwa chogwiritsa ntchito zida zosiyanasiyana, kukhazikika kwamphamvu sikuli bwino ngati kulimba konse. Aloyi kubowola, makamaka ang'onoang'ono diameters.
