Kubowola ndi gawo lofunikira la PCB kayendetsedwe kake kaukadaulo, komanso kusankha kwa kubowola ndikofunikira kwambiri. Chotsekemera cha carbide, chodziwika bwino chifukwa cholumikizana kwambiri pakati pa kubowola nsonga ndi thupi lodula, limatha kukonza mabowo ndi mawonekedwe abwino, kukhululukirana pang’ono komanso kulondola kwa malo. Chotsekera chikatsekedwa, kubowoleza korona kumatha kufikira chakudya chambiri ngati chowotcherera.

Anthu ambiri amaganiza molakwika kuti kubowola kuyenera kuchitidwa pamtengo wotsika komanso mwachangu. Izi zinali zowona, koma ma carbide amakono ndi nkhani ina. M’malo mwake, kusankha gawo loyenera kumatha kukulitsa zokolola ndikuchepetsa mtengo pabowo.

Pali mitundu inayi yayikulu yazobowoleza ndi ma carbide odulira m’mbali omwe angapezeke kwa wogwiritsa ntchito: olimba carbide, oyika indexable, maupangiri owotchera a carbide, ndi maupangiri osinthira a carbide. Iliyonse ili ndi maubwino munjira ina yake.

Zingwe zoyambirira zolimba za carbide zimagwiritsidwa ntchito m’malo opangira zida zamakono. Chopangidwa kuchokera ku carbide yoyera komanso yokutidwa ndi TIAlN ya chida chazida, zidutswa zodzipangira izi zimapereka chiwongolero chabwino kwambiri cha chip ndikuchotsa pazida zambiri zogwirira ntchito chifukwa chamakona awo odulidwa. Ma geometry odziyang’anira pawokha komanso kuwongolera kwazinthu zofunikira za carbide zimatsimikizira kuti mabowo apamwamba amapezeka popanda makina ena.

Masamba osanjika amatenga ma diameters osiyanasiyana mwakuya kuchokera ku 2XD mpaka 5XD. Thiabendazole angagwiritsidwe ntchito ntchito onse makina ndi lathes. Tinthu timeneti timagwiritsa ntchito Angle yojambulitsa yokha pazinthu zambiri zopangira zida zochepetsera kudula ndi kupereka zida zabwino za chip.

Chowotchera cholumikizira chidakonza mabowo ndikumaliza kwapamwamba, kulondola kwambiri komanso mawonekedwe olondola osamalizanso. Ndi kuzirala kudzera m’mabowo, maupangiri a welded atha kugwiritsidwa ntchito m’malo opangira zida zamagetsi, ma lathes a CNC, kapena zida zina zamakina zomwe zimakhala ndi bata lokwanira komanso liwiro lozungulira.

Fomu yomaliza imakhala ndi chodulira chachitsulo chomwe chimakhala ndi malo okhwima otchedwa korona. The kubowola amapereka mwatsatanetsatane monga pokha welded pamene kukwaniritsa zokolola apamwamba pa mtengo wotsika Machining. Mbadwo wotsatirawu wokhala ndi korona wa carbide umapatsa zowonjezerako zowoneka bwino komanso mawonekedwe aumwini omwe amangowoneka bwino.

Ganizirani mosamala za kulolerana ndi zida zama makina

Fakitole iyenera kusankha pang’ono molingana ndi kulolerana komwe kuli pamakinawo. Mabowo ang’onoang’ono m’mimba mwake nthawi zambiri amakhala ndi kulolerana kolimba. Chifukwa chake, opanga pang’ono amagawira zidutswa pofotokoza kutseguka mwadzina komanso kulolerana kwapamwamba. Mwa mitundu yonse ya kubowola, cholimba cha carbide chimakhala ndi kulolerana kolimba. Izi zimawapangitsa kukhala chisankho chabwino pobowola mabowo okhala ndi kulolerana kolimba. Fakitole imatha kubowola ndi 10mm m’mimba wolimba wa carbide pang’ono ndi kulolerana kuyambira 0 mpaka + 0.03mm.

Kumbali imodzi, ma waya otsekedwa kapena ma batire apamwamba okhala ndi korona wosinthika wa carbide amatha kubowoleza kulolerana kuyambira 0 mpaka + 0.07mm. Ma bits awa nthawi zambiri amakhala osankha bwino pobowola.Tsamba lowoneka bwino ndi ntchito yolemetsa m’makampani. Ngakhale mtengo wawo wakutsogolo umakhala wocheperako kuposa mabatani ena, amakhalanso ndi kulolerana kwakukulu, kuyambira 0 mpaka + 0.3mm kutengera makulidwe akuya mpaka dzenje. Izi zikutanthauza kuti wogwiritsa ntchito kumapeto angagwiritse ntchito tsamba lokhala ndi indexable pamene kulolerana kuli kwakukulu, apo ayi ayenera kukhala okonzeka kumaliza dzenje ndi chodulira chosasangalatsa. Pamodzi ndi kulolerana kwa mabowo, fakitaleyo imayenera kuganizira kukhazikika kwa chida chamakina posankha. Chifukwa kukhazikika kuti zitsimikizire moyo wazida komanso kubowola molondola. Fakitoleyo iyenera kutsimikizira momwe makina opangira makina, zolumikizira ndi zida zina zimathandizira. Ayeneranso kulingalira za kukhazikika kwa pang’ono. Mwachitsanzo, monolithic carbide bits imapereka mulingo woyenera kwambiri, womwe umalola kulondola kwakukulu.

Kumbali inayi, timasamba ta masamba osakhazikika timayamba kutembenuka. Tinthu timeneti tili ndi timasamba tiwiri – tsamba lamkati mkatikati ndi tsamba lotambalala panja kuchokera mkati mpaka kumapeto – ndipo tsamba limodzi lokha limatenga gawo locheka. Izi zimapanga mkhalidwe wosakhazikika womwe umapangitsa kuti thupi linyalanyaze. Ndipo kwakukulu kupatuka pang’ono kwa mwezi. Chifukwa chake, mukamagwiritsa ntchito 4XD ndi timitengo tosavuta, masambawo ayenera kulingalira zochepetsa chakudya cha mm woyamba ndikuwonjezera chakudyacho kukhala chabwinobwino. Chotsekemera ndi chopindika cha korona chosandulika chimapangidwa ngati zigawo ziwiri zocheperako zomwe zimapanga Angle yokhazikika. Kukhazikika kotereku kumalola pang’ono kulowa pa workpiece mwachangu. Chokhacho ndi pamene chidacho sichimangoyang’ana pamwamba chomwe chimapangidwa. Tikulimbikitsidwa kuti muchepetse chakudya ndi 30% mpaka 50% panthawi yodulidwa ndi kudula.

Thupi lachitsulo limalola kupatuka pang’ono, ndikupangitsa kuti lizigwiritsidwa ntchito bwino pamakina. Cholimba cha carbide cholimba chimatha kusweka mosavuta, makamaka ngati chopangidwacho sichikhala bwino. Osanyalanyaza tchipisi mafakitale ambiri ali ndi mavuto ndi kuchotsedwa kwa chip. M’malo mwake, kuchotsedwa kwa chip koyipa ndi vuto lomwe limafala kwambiri pobowola, makamaka mukamapanga zitsulo zochepa. Ndipo zilibe kanthu kuti mumagwiritsa ntchito kubowola kotani. Mafakitole nthawi zambiri amagwiritsa ntchito kuzirala kwakunja kuti athetse vutoli, koma kuzama kozama kochepera 1XD komanso kuchepa kwa magawo. Kupanda kutero, ayenera kugwiritsa ntchito chozizira choyenera kuti chifanane ndi kuthamanga ndi kuthamanga kwa kabowo. Pazida zama makina zomwe zilibe malo ozizira ozizira, fakitole iyenera kugwiritsa ntchito choziziritsira kuti chizigwiritsa ntchito. Kumbukirani kuti, dzenje likakhala lozama, kumakhala kovuta kwambiri kuchotsa tchipisi komanso kupsinjika kozizira kumafunikira. Nthawi zonse yang’anani mlingo woyenera woziziritsa wopangira wopanga. Potsika pang’ono, chakudya chochepetsedwa chitha kukhala chofunikira. Kuwona mayendedwe amoyo kukolola kapena mtengo pa bowo ndichimodzi mwazinthu zazikulu kwambiri zomwe zimakhudza kuboola lero. Izi zikutanthauza kuti opanga pang’ono ayenera kupeza njira zophatikizira njira zina ndikupanga ma bits omwe amatha kukhala ndi chakudya chambiri komanso makina othamanga kwambiri.

Ma bits aposachedwa omwe ali ndi maupangiri olimba a carbide amapereka chuma chambiri. M’malo mochotsa thupi lonse, wogwiritsa ntchito wotsiriza amangogula mutu wa carbide womwe umakhala wofanana ndikulembanso pang’ono kapena pang’ono. Koronayu amatha kusinthidwa mosavuta komanso molondola, kulola kuti fakitale igwiritse ntchito zisoti zingapo pathupi limodzi kuti kuboole mabowo osiyanasiyana. Makina osinthira awa amachepetsa mitengo yazinthu zazing’ono ndi mamilimita kuyambira 12mm mpaka 20mm.

Kuphatikiza apo, zimathetsa mtengo wokhala ndi zosunga zobwezeretsera pang’ono pomwe pang’ono kapena yolimba ya carbide ikabwereranso. Fakitaleyo iyeneranso kuganizira za chida chamoyo chonse pounikira mtengo pa phando. Nthawi zambiri, carbide imodzi yokha imatha kuzungulanso kasanu mpaka kasanu mufakitole, pomwe chidutswa chowotchera chimatha kubwereranso katatu kapena kanayi. Mabowolo a korona, komano, ali ndi thupi lodulira lachitsulo lomwe limatha kusintha korona osachepera 20 mpaka 30 kwinaku akupanga chitsulo.

Palinso funso lokolola. Zitsulo zotayidwa kapena zolimba za carbide ziyenera kuzungulira; Chifukwa chake, mafakitole amachepetsa kuthamanga kuti apewe zomata. Komabe, chosinthidwacho sichiyenera kuyambiranso, kotero fakitole imatha kukonza ndi chakudya chokwanira komanso kuthamanga popanda kuda nkhawa ndi simenti ya carbide chip.
