Mukaona chiwonetsero cha malonda a zida zamakina, mudzamva mawu akuti "mineral casting" akuponyedwa pafupifupi nthawi zambiri monga "granite" masiku ano, ndipo mawu awiriwa amasokonezeka nthawi zonse. Ndi ofanana koma si chinthu chomwecho, ndipo kusiyana kwake ndikofunikira ngati mukufuna kudziwa komwe makinawo ali.
Zigawo za granite zachikhalidwe zimadulidwa ndi kuphwanyidwa kuchokera ku chipika chimodzi chogwetsedwa. Kukhetsa mchere, komwe nthawi zina kumatchedwa konkireti ya polymer kapena granite ya epoxy, ndi granite yophwanyidwa kapena basalt aggregate yolumikizidwa pamodzi ndi epoxy resin, kutsanulira mu nkhungu, ndikutsukidwa. Ili pafupi kwambiri ndi konkireti kuposa miyala, kupatulapo aggregate imasankhidwa chifukwa cha mphamvu zake zamagetsi ndipo resin matrix imapangidwa mwaluso osati mwangozi.
Chifukwa chiyani wina angasankhe mwala wolimba kuposa wopangidwa ndi zinthu zina
Yankho lodziwikiratu ndi la geometry. Chipilala cha granite chogwetsedwa chimachepetsedwa ndi zomwe chilengedwe chimapanga komanso zomwe soka lingathe kudula. Kupangira mchere kumatha kutsanulidwa m'mawonekedwe ovuta - nthiti zamkati, njira zoziziritsira, mabowo oyika - mu sitepe imodzi, zomwe zimakhala zovuta kapena zosatheka kuzipanga kukhala granite yolimba popanda zinyalala zambiri.opanga opanga maziko a makinakuchuluka kwake, ndi phindu lenileni komanso nthawi yoti zinthu ziyende bwino.
Nkhani ya kunyowetsa nthaka ndi yabwino kwambiri pakupangira miyala kuposa granite yolimba. Matrix a resin amayamwa kugwedezeka bwino kwambiri kuposa kapangidwe ka miyala ya kristalo yokha, zomwe ndi chimodzi mwa zifukwa zomwe kupangira miyala kumaonekera nthawi zambiri m'mabedi a zida zamakina a CNC ndi mafelemu a makina opukutira komwe kuletsa phokoso panthawi yodula kumakhala vuto lalikulu kuposa kukhazikika kwathunthu kwa kutentha.
Kumene granite yolimba imapambanabe
Komabe, kuyika mchere sikusintha kokhwima. Granite yolimba yomwe yagwetsedwa nthawi zambiri imakhala ndi coefficient yotsika komanso yodziwikiratu ya kukula kwa kutentha, ndipo chifukwa ilibe gawo la polima, ilibe mawonekedwe ofanana ndi omwe amachotsa mpweya kwa nthawi yayitali kapena kuyamwa chinyezi monga momwe ma epoxy resins angasonyezere. Pazinthu monga mabenchi optical, ma laser interferometry platforms, kapena zida zoyezera malo oyeretsa komwe kukhazikika kwa miyeso kwa zaka zambiri kumakhala kofunikira kuposa kunyowetsa panthawi yodula, granite yolimba nthawi zambiri imakhalabe chinthu chomwe chimakondedwa.
Ichi ndichifukwa chake opanga zida zodziwika bwino amagwiritsa ntchito zonse ziwiri, zogwirizana ndi ntchito m'malo mosankha chinthu chimodzi ngati muyezo wamba: kuponyera mchere pamafelemu a zida zamakina ndi maziko omangira omwe amafunika kupangidwa m'mawonekedwe ovuta ndikuyamwa kugwedezeka kodula, granite yolimba yoyezera nsanja, malo okhala ndi mpweya, ndi mapulaneti ofotokozera komwe ma microns amasunthika kwa zaka khumi ndi chinthu chomwe mukuyesera kupewa.
Chidziwitso chothandiza kwa ogula
Ngati wogulitsa atchula mawu akuti "granite" popanda kutchula ngati ndi miyala yosweka kapena miyala yopangidwa ndi mineral, ndikofunikira kufunsa mwachindunji - kusiyana kwa mitengo, mawonekedwe omwe angatheke, ndi mawonekedwe okhazikika kwa nthawi yayitali ndizosiyana mokwanira kotero kuti kusiyana kuyenera kukhala gawo la pepala lililonse laukadaulo, osati lingaliro lomaliza. Pa ntchito yolondola kwambiri ya metrology, kufunsa kuchuluka kwenikweni, CTE (coefficient of thermal expansion), ndi kulekerera kwa flatness komwe kumachitika - m'malo modalira dzina la zinthu zokha - ndiyo njira yokhayo yodalirika yofananizira mawu ochokera kwa opanga osiyanasiyana.
