Chipinda chanu chapamwamba chili pansi.
Ayi, sichinaganize mwadala kuti chikusocheretseni. Koma ngati ndi chitsulo chopangidwa ndi chitsulo ndipo mwakhala mukugwiritsa ntchito 5-axis m'mawa wonse ndi coolant ikupopera kulikonse, pali mwayi waukulu kuti kuwerenga komwe mukupeza sikofanana ndi momwe mukuganizira.
Izi ndi zomwe zimachitikadi: chitsulo chosungunuka chimayamwa chinyezi, chimayamwa ndi zinthu zoziziritsira zochokera m'madzi, ndipo chimayamba kuchita dzimbiri kuyambira nthawi yomwe mwasiya kuipaka mafuta. Ngakhale m'masitolo ouma, kusintha kwa kutentha kumapangitsa kuti ikule ndikuchepa nthawi zonse. Ikani gawo lolondola pa mbaleyo nthawi ya 8 koloko m'mawa pamene sitoloyo ili yozizira, kenako yang'anani gawo lomwelo nthawi ya 2 koloko masana makina akakhala akugwira ntchito kwa maola ambiri—manambalawo sangagwirizane. Ndipo ngati mukudabwa chifukwa chake CMM yanu imapitilizabe kulephera kuphunzira luso ngakhale kuti zinthu zikuwoneka zofanana, malo anu ofotokozera akhoza kukhala omwe amachititsa kuti zinthu zisamayende bwino.
Zipangizo zoyezera granite zilibe vuto ili.
Sikuti ndi zamatsenga. Koma kuchuluka kwa kutentha kwa granite kumakhala pafupifupi 4.5 × 10⁻⁶/°C—pafupifupi gawo limodzi mwa magawo atatu kuposa chitsulo chopangidwa ndi chitsulo. Pa nthawi ya 600mm, kugwedezeka kwa 5°C kumabweretsa kusintha kwa miyeso ya granite kwa 0.001mm poyerekeza ndi 0.012mm kapena kuposerapo pa chitsulo chopangidwa ndi chitsulo. Pakukonza molondola komwe mukumenyera kulekerera kwa 0.005mm, kusiyana kumeneko pakati pa kupitirira ndi kuchotsedwa.
Sitolo ina yomwe ndinamva za kusintha malo awo owunikira kuchokera ku chitsulo chopangidwa ndi granite kupita ku granite ndipo nthawi yomweyo ndinazindikira kuti kuchuluka kwa zinyalala zawo kwatsika—osati chifukwa makina awo anali bwino, koma chifukwa chakuti njira yawo yoyezera pamapeto pake inali yoona.
Chinthu chabwino kwambiri chokhudza granite, ndipo izi sizikukambidwa kwambiri, ndi momwe imachitira ndi kuwonongeka.
Kodi mwagwetsa chipika choyezera pa mbale yachitsulo chopangidwa ndi chitsulo? Mungapeze chivundikiro chokwezedwa. Kapangidwe kakang'ono kameneka kamakhala kodzitamandira ndi pamwamba pake, ndipo tsopano chidutswa chilichonse chomwe mumayang'ana pamalopo chikuyesa molakwika. Palibe chenjezo, palibe chizindikiro chowoneka—kungosonkhanitsa zolakwika mwakachetechete.
Kodi mwagunda geji yomweyo motsutsana ndi granite? Mupeza chip. Mwina dzenje laling'ono. Koma nayi nkhani—malo ena onse akadali athyathyathya. Mutha kugwiritsa ntchito malo osawonongeka motsimikiza. Cholakwikacho chili pamalo amodzi ndipo chikuwonekeratu, sichinabisike ndipo chikufalikira.
Izi ndizofunikira kwambiri kuposa momwe anthu amaganizira m'malo opangira zinthu kumene ma plates opangidwa pamwamba amawonongeka tsiku ndi tsiku.
Kutentha kwa mpweya ndiko kupha mwakachetechete pakupanga zinthu molondola.
Tangoganizirani izi: mukugwira ntchito Lolemba m'mawa. Kutentha kwa shopu ndi 18°C. Munthu wanu wokonza zinthu akuyang'ana miyeso yonse yofunika, chilichonse chikuwoneka bwino, zida zikugwira ntchito. Kenako Lachisanu masana likufika, ndipo mwadzidzidzi katswiri wa QC akuwonetsa zida zomwe zinali bwino sabata yonse. Kodi n'chiyani chinasintha? Makina sanasinthe. Ogwiritsa ntchito sanasinthe. Koma kutentha kwa mlengalenga kunasintha—mwina madigiri 4 kapena 5 pamene makina a HVAC akuvutika ndi nyengo ya kumapeto kwa sabata, kapena pamene dzuwa likusuntha ndikutentha mbali imodzi ya nyumbayo.
Mapepala achitsulo opangidwa ndi chitsulo adzakula ndi kupindika ndi ma swing awa. Granite sidzagwira ntchito.
Ichi ndichifukwa chake ma labotale apamwamba kwambiri akugwiritsa ntchito granite kwa zaka zambiri. Si mwambo—ndipo granite imakupatsani chizindikiro chomwe sichimayenderana ndi chilengedwe.
Chinthu china chomwe chimayiwalika: kuletsa vibration.
Malo opangira makina amakono amanjenjemera. Ma spindles pa 15,000 RPM, njira zoyendera mwachangu, zida zamagetsi—zonse zimapanga mphamvu yamakina yomwe imadutsa kudzera pa bedi la makina, kudutsa pansi, kupita kumalo omwe mukuyezera. Pamwamba pa chitsulo chopangidwa ndi chitsulo, kugwedezeka kumeneko kumapitirira. Singano yanu yoyikira chizindikiro imagwedezeka. Kuwerenga kwanu kwa digito kumasinthasintha. Mukuyesera kuwerenga 0.001mm pamene makina anu onse akugwedezeka.
Granite imayamwa mphamvu imeneyo. Mphamvu yake yachilengedwe yochepetsera chinyezi imakwera pafupifupi nthawi khumi kuposa chitsulo chopangidwa ndi chitsulo. Zili ngati kuyika njira yanu yoyezera pa chonyamulira kugunda kwa mtima. Manambalawo amakhazikika mwachangu, kuwerenga kumabwerezedwa, ndipo mutha kukhulupirira zomwe mukuwona.
Ngati mukudabwa za mapulogalamu enieni, nayi zomwe mwina mukukumana nazo:
Ma plates apamwamba kuti ayang'anire ndi kuyika—kuyang'ana kusalala, kufanana, ndi sikweya. Masitolo ambiri amafunikira mbale imodzi yabwino yowunikira malo awo okonzera.
Ma sikweya abwino kwambiri kuti muwone ngati CNC yanu ili yolunjika. Ngati makina anu ali ndi sikweya, gawo lililonse lomwe mumapanga lili ndi cholakwika chimenecho. Kuchita cheke cha masikweya atatu sabata iliyonse kumatenga mphindi zisanu ndipo kumabweretsa mavuto asanakhale mavuto a gawo.
Ma V-blocks ogwirira ziwalo zozungulira panthawi yowunikira. Zozungulira zimakhala zovuta kuziyeza nthawi zonse—ma V-blocks amathetsa vutoli.
Mphepete zowongoka kuti muwone momwe makina amagwirira ntchito komanso malo akuluakulu omwe simungathe kuyika mbale.
Kufanana kwa kukweza ma workpieces kuti muthe kupeza zinthu zomwe zikanabisika.
Kudziwa bwino za magiredi: ntchito zambiri zolondola zogwirira ntchito zimafuna Giredi 00. Zimenezi zimakupatsani kulekerera kwapafupifupi ma micrometer 1.5 pa mita imodzi. Giredi 0 ndi yocheperako pa ma micrometer 4—ndi yabwino poyang'anitsitsa bwino koma osati pogwira ntchito molimbika. Giredi 000 ndi chinthu chogwiritsidwa ntchito mu labotale, ma micrometer 0.5 kapena kupitirira apo, ndipo moona mtima ndi yochulukirapo pokhapokha ngati muli mu ntchito yowunikira kapena yowunikira ndege.
Lamulo limene ndimagwiritsa ntchito: zida zanu zowunikira ziyenera kukhala zolondola kwambiri kuposa magiredi amodzi kapena awiri kuposa ma tolerance omwe mukuyesera kusunga. Ngati kulekerera kwanu koyipa kwambiri ndi ±0.02mm, mbale ya Giredi 0 (kulekerera pafupifupi 0.004mm/m2) imakupatsani mwayi wabwino.
Kusamalira n'kosavuta ndipo moona mtima, granite ndi wokhululukira.
Sungani yoyera. Pukutani mutagwiritsa ntchito, makamaka ngati mwakhala mukugwiritsa ntchito madzi odulira. Gwiritsani ntchito granite yoyenera kapena chotsukira mbale pamwamba, osati mankhwala opangidwa mwachisawawa. Thandizani mbale zazikulu bwino pa malo oimikapo zinthu—chithandizo chosayenera chimapangitsa kuti m'mphepete mwa mbaleyo mupatuke ndipo chimawononga mawonekedwe anu osalala.
Pezani ziphaso zovomerezeka nthawi ndi nthawi. Kubwezeretsanso ziphaso pachaka kwa ma plate omwe amagwiritsidwa ntchito kwambiri, zaka zingapo zilizonse kwa zinthu zochepa. Sizokwera mtengo, ndipo zimakupatsani umboni wotsimikizira kuti ma reference anu akadali abwino.
Nayi poyambira kothandiza ngati mukufuna kusintha:
Dziwani malo anu ofunika kwambiri—omwe mumagwiritsa ntchito poyang'ana komaliza pazigawo zanu zolimba kwambiri. Apa ndi pomwe granite imapanga kusiyana kwakukulu.
Kenako yang'anani momwe ntchito yanu yowunikira imayendera. Kodi mukutaya nthawi kuti mukulimbana ndi mawerengedwe osasinthasintha? Kodi mukuganiza kuti pali cholakwika choyezera koma simungathe kutsimikizira? Amenewo ndi omwe mukufuna kugwiritsa ntchito zida za granite yachiwiri ndi yachitatu.
Simukuyenera kusintha chilichonse nthawi imodzi. Koma kusinthana ndi mbale imodzi kapena ziwiri za key kudzakuuzani mwachangu ngati granite ndi yoyenera kuyika ndalama mu ntchito yanu.
Masitolo ambiri omwe amasinthira sabwerera m'mbuyo.
