Kubowola ndi njira yofala kwambiri yopangira popanga.Pogula zobowola, zobowola zimabwera muzinthu zosiyanasiyana ndi mitundu yosiyanasiyana.Ndiye kodi mitundu yosiyanasiyana ya mabowo amathandizira bwanji?Kodi mtundu uli ndi chochita ndi mtundu wa kubowola?Ndi mtundu uti wa kubowola womwe uli bwino kugula?
Choyamba, tiyenera kufotokoza momveka bwino kuti khalidwe la kubowola silingayesedwe ndi mtundu wake.Palibe mgwirizano wolunjika ndi wosapeŵeka pakati pa mtundu ndi khalidwe.Mitundu yosiyanasiyana ya mabowobowola makamaka chifukwa cha njira zosiyanasiyana zopangira.Zachidziwikire, titha kupanga chigamulo chaukali potengera mtundu, koma zobowola zamasiku ano zobowola bwino zithanso kupanga mitundu yawoyawo kuti ziwonekere zobowola zapamwamba kwambiri.
Ndiye pali kusiyana kotani pakati pa mabowo amitundu yosiyanasiyana?
Zitsulo zobowola zitsulo zothamanga kwambiri zapamwamba kwambiri nthawi zambiri zimapezeka zoyera.Zachidziwikire, chobowolacho chimatha kuyeretsedwanso pogaya bwalo lakunja.Zomwe zimawapangitsa kukhala apamwamba kwambiri sizinthu zokhazokha, komanso kuwongolera khalidwe panthawi yopera.Ndizovuta kwambiri ndipo sipadzakhala zopsereza pamwamba pa chida.Zakuda ndi zitsulo za Nitride.Ndi njira yamankhwala yomwe imayika chida chomalizidwa mu chisakanizo cha ammonia ndi nthunzi yamadzi ndikuchita chithandizo chotetezera kutentha pa 540 ~ 560C ° kuti chikhale cholimba cha chidacho.Zambiri mwazitsulo zakuda zobowola pakali pano pamsika zimakhala zakuda zokha (pofuna kubisa zoyaka kapena khungu lakuda pamwamba pa chida), koma kugwiritsa ntchito kwenikweni sikunasinthidwe bwino.
Pali njira zitatu zopangira ma drill bits.Kugudubuzika kwakuda ndiye koyipa kwambiri.Zoyera zili ndi m'mbali zowoneka bwino komanso zopukutidwa.Popeza makutidwe ndi okosijeni wotentha kwambiri sikofunikira, kapangidwe ka chitsulocho sichidzawonongeka, chitha kugwiritsidwa ntchito pobowola zida zogwirira ntchito zolimba pang'ono.Zobowola zachikasu zofiirira zimakhala ndi cobalt, lomwe ndi lamulo losanenedwa mumakampani obowola.Ma diamondi okhala ndi cobalt amakhala oyera, koma kenako amasinthidwa kukhala achikasu-bulauni (omwe amadziwika kuti amber).Iwo ndi ena mwa abwino kwambiri omwe akufalitsidwa.M35 (Co 5%) ilinso ndi mtundu wa golide wotchedwa titaniyamu-plated drill bit, yomwe imagawidwa muzopaka zokongoletsera ndi zokutira mafakitale.Kukongoletsa kokongoletsera sikuli bwino, kumangowoneka kokongola.Zotsatira za electroplating ya mafakitale ndizabwino kwambiri.Kuuma kumatha kufikira HRC78, komwe ndikwapamwamba kuposa kulimba kwa kubowola kwa cobalt (HRC54 °).
Momwe mungasankhire pobowola
Popeza mtundu si muyeso woyezera mtundu wa kubowola pang'ono, momwe mungasankhire pobowola?
Malinga ndi zomwe wakumana nazo, zobowola zoyera nthawi zambiri zimakhala zobowola zitsulo zothamanga kwambiri ndipo ziyenera kukhala zabwino kwambiri.Zagolide zili ndi zokutira za titaniyamu nitride ndipo nthawi zambiri zimakhala zabwino kwambiri kapena zoyipa kwambiri ndipo zimatha kupusitsa anthu.Ubwino wakuda umasiyananso.Ena amagwiritsa ntchito chitsulo chotsika kwambiri cha carbon, chomwe ndi chosavuta kuchiza ndi kuchita dzimbiri, choncho chiyenera kudetsedwa.
Pa shank ya kubowola, pali zizindikiro za chizindikiro ndi m'mimba mwake, zomwe nthawi zambiri zimakhala zomveka bwino, ndipo ubwino wa laser ndi electro-etching sikuyenera kukhala woipa kwambiri.Ngati zilembo zowumbidwa zili ndi m'mphepete mwa ma convex, zikuwonetsa kuti chobowolacho ndi chosawoneka bwino, chifukwa mawonekedwe amtundu wa otchulidwawo apangitsa kuti kubowola kulephera kukwaniritsa zofunikira.Mphepete mwa mawuwo imagwirizanitsidwa bwino ndi cylindrical pamwamba pa workpiece, ndi kubowola pang'ono ndi m'mphepete momveka bwino mawu ndi khalidwe labwino.Muyenera kuyang'ana kabowo kakang'ono kokhala ndi nsonga yabwino pansonga.Kubowola pansi kokwanira kumakhala ndi m'mphepete mwabwino kwambiri ndipo kumakwaniritsa zofunikira pa malo a helix, pomwe zobowola bwino zimakhala ndi malo osavomerezeka bwino.
