Magawo aukadaulo ndi miyezo ya granite mechanical base.

 

Granite yadziwika kale ngati chinthu choyambirira pamakina oyambira chifukwa cha mawonekedwe ake apadera, kuphatikiza kuchulukira kwakukulu, kulimba, komanso kukana kukula kwamafuta. Kumvetsetsa zaukadaulo ndi miyezo yolumikizidwa ndi maziko amakina a granite ndikofunikira kwa mainjiniya ndi opanga omwe amadalira kulondola komanso kulimba pakugwiritsa ntchito kwawo.

Chimodzi mwazinthu zaukadaulo zamakina amakina a granite ndi mphamvu yake yopondereza, yomwe nthawi zambiri imakhala kuyambira 100 mpaka 300 MPa. Mphamvu yopondereza iyi imatsimikizira kuti granite imatha kupirira katundu wambiri popanda kupindika, ndikupangitsa kuti ikhale yabwino kuthandizira makina olemera ndi zida. Kuphatikiza apo, miyala ya granite imawonetsa ma coefficients ocheperako otentha, nthawi zambiri pafupifupi 5 mpaka 7 x 10 ^ -6 / ° C, zomwe zimachepetsa kusintha kwa mawonekedwe chifukwa cha kusinthasintha kwa kutentha, kuwonetsetsa kuti magwiridwe antchito azichitika m'malo osiyanasiyana.

Kusalala kwapamtunda ndi mulingo wina wofunikira pamakina amakina a granite. Kulekerera kwa flatness nthawi zambiri kumatchulidwa mu micrometers, ndi ntchito zolondola kwambiri zomwe zimafuna kulolerana kolimba ngati 0.005 mm pa mita. Mlingo wolondolawu ndi wofunikira pakugwiritsa ntchito monga makina oyezera (CMMs) ndi zida zowunikira, pomwe ngakhale kupatuka pang'ono kungayambitse zolakwika zazikulu zoyezera.

Kuphatikiza apo, makulidwe a granite nthawi zambiri amachokera ku 2.63 mpaka 2.75 g/cm³, zomwe zimapangitsa kukhazikika kwake komanso kugwetsa kugwedera. Makhalidwewa ndi ofunikira pochepetsa kugwedezeka kwa kugwedezeka kwakunja, potero kumathandizira kulondola kwa zida zomwe zimayikidwa pamiyala ya granite.

Pomaliza, magawo aukadaulo ndi miyezo yamakina a granite mechanical bases amatenga gawo lofunikira pakugwiritsa ntchito kwawo m'mafakitale osiyanasiyana. Potsatira izi, opanga amatha kutsimikizira kudalirika ndi magwiridwe antchito a zida zawo, zomwe zimapangitsa kuti pakhale kuwongolera magwiridwe antchito komanso kulondola pakupanga. Pamene ukadaulo ukupita patsogolo, kufunikira kwa maziko amakina apamwamba kwambiri a granite kupitilira kukula, kutsimikizira kufunikira komvetsetsa mfundo zaukadaulozi.
