Mu zida zowongolera manambala za CNC, ngakhale granite yakhala chinthu chofunikira kwambiri chifukwa cha mawonekedwe ake apadera, zovuta zake zomwe zingakhudzenso magwiridwe antchito a zida, kukonza bwino komanso mtengo wokonza. Zotsatirazi ndikuwunika kwazomwe zimadza chifukwa cha zolakwika za granite kuchokera ku miyeso ingapo:
Choyamba, zinthuzo zimakhala zowonongeka kwambiri ndipo zimatha kusweka ndi kuwonongeka
Core drawback: Granite ndi mwala wachilengedwe ndipo ndi chinthu chophwanyika komanso chosalimba kwambiri (mtengo wamphamvu ndi pafupifupi 1-3J/cm², womwe ndi wotsika kwambiri kuposa 20-100J/cm² wazitsulo zachitsulo).
Zokhudza zida za CNC:
Kuyika ndi zowopsa zoyendetsa: Pakusonkhanitsa kapena kugwiritsira ntchito zipangizo, ngati zitagwedezeka kapena kugwa, zigawo za granite (monga maziko ndi njanji zowongolera) zimakhala zosavuta kung'amba kapena kung'ambika ngodya, zomwe zimapangitsa kuti zikhale zovuta kulondola. Mwachitsanzo, ngati nsanja ya granite yamakina atatu oyezera ikupanga ming'alu yobisika chifukwa cha kusagwira ntchito moyenera pakuyika, kungayambitse kuwonongeka kwapang'onopang'ono kwa flatness pakugwiritsa ntchito nthawi yayitali, zomwe zimakhudza zotsatira zake.
Zowopsa zobisika pakukonza: Zida za CNC zikakumana ndi kuchuluka kwadzidzidzi (monga chida chogundana ndi chogwirira ntchito), njanji zowongolera za granite kapena ma worktables amatha kusweka chifukwa chakulephera kupirira mphamvu yanthawi yomweyo, kupangitsa kuti zida zizimitsidwa kuti zikonzedwe, ndipo ngakhale kuyambitsa kulephera kwatsatanetsatane.
Chachiwiri, zovuta zowonongeka zimalepheretsa kupanga mapangidwe ovuta
Zovuta zapakati: Granite imakhala ndi kuuma kwakukulu (6-7 pa sikelo ya Mohs), ndipo imayenera kugwedezeka ndi kukonzedwa ndi zida zapadera monga mawilo a diamondi, zomwe zimapangitsa kuti ntchito ikhale yotsika kwambiri (kugwiritsa ntchito mphero ndi 1/5 mpaka 1/3 ya zipangizo zachitsulo), ndipo mtengo wokonza malo okhotakhota ndi apamwamba.
Zokhudza zida za CNC:
Zolepheretsa mapangidwe apangidwe: Pofuna kupewa zovuta zogwirira ntchito, zigawo za granite nthawi zambiri zimapangidwira m'mawonekedwe osavuta a geometric (monga mbale, njanji zowongolera zamakona anayi), zomwe zimapangitsa kuti zikhale zovuta kukwaniritsa zingwe zamkati, mbale zolimba zopepuka ndi zina zomwe zimatha kukwaniritsidwa poponya / kudula ndi zida zachitsulo. Izi zimabweretsa kuti kulemera kwa maziko a granite nthawi zambiri kumakhala kwakukulu kwambiri (10% -20% yolemera kuposa chitsulo chosungunuka kwa voliyumu yomweyi), zomwe zingapangitse katundu wonse wa zida ndi kukhudza kuyankha kwamphamvu pamayendedwe othamanga kwambiri.
Kukonza kwakukulu ndi ndalama zosinthira: Pamene kuvala kapena kuwonongeka kwa m'deralo kumachitika pazigawo za granite, zimakhala zovuta kuzikonza pogwiritsa ntchito njira monga kuwotcherera kapena kudula. Kawirikawiri, chigawo chonsecho chiyenera kusinthidwa, ndipo zigawo zatsopanozi ziyenera kukonzedwanso ndi kuyesedwa kuti zikhale zolondola, zomwe zimapangitsa kuti pakhale nthawi yayitali (kulowetsa kamodzi kungatenge masabata a 2-3), ndi kuwonjezeka kwakukulu kwa ndalama zowonongeka.
Iii. Kusatsimikizika kwa Zopangidwe Zachilengedwe ndi Zowonongeka Zamkati
Core drawback: Monga mchere wachilengedwe, granite imakhala ndi ming'alu yosalamulirika yamkati, pores kapena zonyansa zamchere, ndipo mawonekedwe amtundu wa mitsempha yosiyanasiyana amasiyana kwambiri (kusinthasintha kwa kachulukidwe kumatha kufika ± 5%, kusinthasintha kwa modulus ± 8%).
Zokhudza zida za CNC:
Chiwopsezo chokhazikika chokhazikika: Ngati malo opangira chigawocho amakhala ndi ming'alu yamkati, pakagwiritsidwe ntchito kwa nthawi yayitali, ming'alu imatha kukulirakulira chifukwa cha kupsinjika, kuchititsa kusinthika kwapaderalo komanso kukhudza kulondola kwa zida. Mwachitsanzo, ngati njanji zowongolera ma granite zamakina opera a CNC zili ndi mabowo a mpweya obisika, amatha kugwa pang'onopang'ono ndikugwedezeka kwanthawi yayitali, zomwe zimapangitsa kuti njanji zowongoka kwambiri zikhale zolakwika.
Kusiyana kwa magwiridwe antchito: Zida za granite zochokera m'magulu osiyanasiyana zimatha kukhala ndi kusinthasintha kwazizindikiro zazikulu monga kuchuluka kwa kukulitsa kwamafuta ndi magwiridwe antchito chifukwa cha kusiyana kwa kapangidwe ka mchere, komwe kumakhudza kusasinthika kwa kupanga batch ndi zida. Kwa mizere yopangira makina yomwe imafunikira kulumikizana kwa zida zingapo, kusiyana kotereku kungayambitse kufalikira kwa kulondola kwa kukonza.
Chachinayi, ndi cholemetsa, chomwe chimakhudza machitidwe amphamvu a zipangizo
Kore drawback: Granite ali ndi kachulukidwe kwambiri (2.6-3.0g/cm³), ndipo kulemera kwake ndi pafupifupi 1.2 kuwirikiza chitsulo chotayidwa ndi 2.5 kuwirikiza kwa aluminum alloy pansi pa voliyumu yomweyo.
Zokhudza zida za CNC:
Kuyankha kwaposachedwa: M'malo opangira makina othamanga kwambiri kapena makina aaxis asanu, kuchuluka kwakukulu kwa maziko a granite kumawonjezera kuchuluka kwa zomangira zamoto / kutsogolo wononga, zomwe zimapangitsa kuchedwa kwachangu pakuyankha pakuthamanga / kutsika (zomwe zitha kuwonjezera nthawi yoyimitsa ndi 5% mpaka 10%), zomwe zimakhudza magwiridwe antchito.
Kugwiritsa ntchito mphamvu zowonjezera: Kuyendetsa zigawo zolemera za granite kumafuna ma servo motors amphamvu kwambiri, omwe amakweza mphamvu zonse zogwiritsira ntchito zipangizo (miyeso yeniyeni imasonyeza kuti pansi pa ntchito zomwezo, mphamvu yogwiritsira ntchito zida za granite ndi 8% -12% kuposa zida zachitsulo). Kugwiritsa ntchito nthawi yayitali kumawonjezera ndalama zopangira.
Chachisanu, kuthekera kokana kugwedezeka kwa kutentha kumakhala kochepa
Core drawback: Ngakhale granite ili ndi coefficient yotsika yowonjezera kutentha, kutentha kwake kumakhala kosauka (ndi kutentha kwa 1.5-3.0W / (m · K), pafupifupi 1/10 ya chitsulo choponyedwa), ndipo kusintha kwadzidzidzi kutentha kwapafupi kumakhala kosavuta kutulutsa kupsinjika kwa kutentha.
Zokhudza zida za CNC:
Kutentha kusiyana nkhani m'dera processing: Ngati madzi odulira concentratatively kukokoloka m'dera la granite worktable, zingachititse kutentha gradient (monga kutentha kusiyana 5-10 ℃) pakati pa dera lino ndi dera lozungulira, kutsogolera ku mapindikidwe ang'onoang'ono matenthedwe (mapindikidwe kuchuluka angafikire 1-3μm), zomwe zimakhudza kulondola kwa giya consinding monga kulondola kwa giya losasunthika.
Chiwopsezo cha kutopa kwanthawi yayitali: M'malo ochitira msonkhano omwe amayamba ndi kutseka pafupipafupi kapena kutentha kwakukulu pakati pa usana ndi usiku, zigawo za granite zimatha kukhala ndi ma microcracks chifukwa cha kuwonjezereka kwamafuta mobwerezabwereza ndi kutsika, kufooketsa kulimba kwamapangidwe.
