Magadzirirwo ehunyanzvi uye mwero wechigadziko chegranite mechanical.

 

Granite yagara ichizivikanwa sechinhu chakakosha pakugadzira mabhesi emakanika nekuda kwehunhu hwayo hwakasiyana, kusanganisira kuwanda kwesimbi, kuomarara, uye kuramba kupisa kwakanyanya. Kunzwisisa hunyanzvi hwemagadziko emakanika egranite kwakakosha kune mainjiniya nevagadziri vanovimba nekunyatsorongeka uye kugara kwenguva refu mukushandiswa kwavo.

Chimwe chezvinhu zvikuru zvekushandisa granite mechanical bases isimba rayo rekudzvanya, iro rinowanzova pakati pe100 ne300 MPa. Simba iri rekudzvanya rinoita kuti granite ikwanise kutsungirira mitoro yakakura isina kuchinja, zvichiita kuti ive yakakodzera kutsigira michina nemidziyo inorema. Pamusoro pezvo, granite inoratidza thermal expansion coefficients yakaderera, kazhinji inenge iri pakati pe5 ne7 x 10^-6 /°C, izvo zvinoderedza shanduko dzehukuru nekuda kwekuchinja kwetembiricha, zvichiita kuti ishande zvakanaka munzvimbo dzakasiyana-siyana.

Kusatsetseka kwepamusoro ndeimwe nzira yakakosha yekuisa mabhesi egranite. Kushivirira kusatsetseka kunowanzo tsanangurwa muma micrometer, nemashandisirwo akanyatsojeka anoda kuti kushivirira kwakasimba se 0.005 mm pa mita. Kunyatsojeka uku kwakakosha kumashandisirwo akadai semichina yekuyera (CMMs) nemidziyo yemaziso, uko kunyangwe kutsauka kudiki kunogona kukonzera zvikanganiso zvakakura pakuyera.

Uyezve, huwandu hwegranite hunowanzova pakati pe2.63 ne2.75 g/cm³, zvichibatsira kuti igare yakasimba uye inoderedza kudedera. Hunhu uhwu hwakakosha mukuderedza kukanganiswa kwekutedera kwekunze, nokudaro zvichiwedzera kururama kwezvishandiso zvinonzwa zviri pamatombo egranite.

Mukupedzisa, zviyero zvehunyanzvi uye mwero wezvigadziko zvegranite mechanical zvinoita basa guru mukushandiswa kwazvo mumaindasitiri akasiyana-siyana. Nekutevedzera zvinodiwa izvi, vagadziri vanogona kuve nechokwadi chekuvimbika uye kushanda kwemidziyo yavo, zvichizoguma nekuvandudza kushanda zvakanaka uye kururama mumabasa ekugadzira. Sezvo tekinoroji ichifambira mberi, kudiwa kwezvigadziko zvegranite mechanical zvemhando yepamusoro kucharamba kuchikura, zvichisimbisa kukosha kwekunzwisisa zviyero izvi zvehunyanzvi.
