Munyika ye metrology yekuyera zvinhu nemazvo, chishandiso chekuyera granite hachisi dombo rinorema chete; ndicho chiyero chakakosha chinoyerwa zvimwe zviyero zvese. Kururama kwekupedzisira—kwakawanikwa mu micron ne sub-micron—kunotanga kare kare maitiro ekupedzisira ekukweva nekukweva. Asi ndeapi maitiro ekutanga akagadzira nzira yekunyatsojeka kwakadaro? Inotanga nematanho maviri akakosha, ekutanga: kusarudzwa kwakasimba kwezvinhu zvegranite zvisina kugadzirwa uye maitiro ekucheka akanyanya kushandiswa kuigadzira.
Unyanzvi neSainzi yeKusarudza Zvinhu
Haasi magranite ese akaenzana, kunyanya kana chigadzirwa chekupedzisira chichifanira kushanda sechishandiso chekuyera chakasimba, chemhando yepamusoro senge plate yepamusoro, tri-square, kana straight edge. Maitiro ekusarudza ndeesainzi, achitarisa pane hunhu hwepanyama hunovimbisa kugadzikana kwehukuru kwemakumi emakore.
Tinotsvaga mhando dzegranite nhema dzine huwandu hwakanyanya. Ruvara rwunoratidza huwandu hwakawanda hwezvicherwa zvakasviba, zvakaita sehornblende, uye chimiro chezviyo zvakapfava. Musanganiswa uyu haugone kutaurwa nezvawo kuti pave nekushanda kwakarurama nekuda kwezvikonzero zvakawanda zvakakosha. Chekutanga, Low Porosity uye High Density zvakakosha: chimiro chakasimba, chine ganda rakapfava chinoderedza maburi emukati uye chinowedzera huwandu, izvo zvinoshandura zvakananga kune hunhu hwepamusoro hwekunyorovesa mukati. Kugona uku kwakanyanya kwekunyorovesa kwakakosha kuti muchina utore nekukurumidza kutenderera, kuve nechokwadi chekuti nzvimbo yekuyera inoramba yakagadzikana zvachose. Chechipiri, chinhu ichi chinofanira kuratidza Low Coefficient of Thermal Expansion (COE) zvakanyanya. Hunhu uhwu hwakakosha, sezvo hunoderedza kuwedzera kana kudzikira nekuchinja-chinja kwekushisa kwakajairika munzvimbo yekudzora mhando, zvichivimbisa kuti chishandiso chinochengetedza divi rayo rakasimba. Chekupedzisira, granite yakasarudzwa inofanira kuva nesimba rekudzvanya uye Uniform Mineral Distribution. Kufanana uku kunoita kuti chinhu ichi chipindure nenzira inofanotaurwa panguva yekucheka kunotevera uye, zvakanyanya kukosha, chikamu chakakosha chekubata nemaoko, zvichitibvumira kuwana uye kuchengetedza kushivirira kwedu kwakasimba kwekutsamira.
Maitiro Ekucheka Akanyatsonaka
Kana bhuroko rakakodzera rabviswa kubva mugomba, danho rekutanga rekuumba—kucheka—ibasa remaindasitiri rakagadzirirwa kuderedza kushushikana kwezvinhu uye kugadzira nzira yekupedzisa nemazvo. Nzira dzekucheka masonry dzakajairwa hadzina kukwana; granite chaiyo inoda maturusi akasarudzika.
Nzira yemazuva ano yekucheka mabhuroko makuru egranite ndiyo Diamond Wire Saw. Nzira iyi inotsiva maburi ekare akatenderera netambo yesimbi yakasimba ine madhaimani eindasitiri. Kushandiswa kwenzira iyi kune zvakanakira zvakasiyana: inoita kuti pave neKudzikira Kwepfungwa Nekupisa nekuti dhaimani yewaya inoshanda nenzira inoramba ichienderera mberi, ichifamba-famba, iyo inogovera masimba ekucheka zvakaenzana pakati pezvinhu. Izvi zvinoderedza njodzi yekuunza kushushikana kwakasara kana kutsemuka kudiki mugranite—njodzi inowanzoitwa nenzira dzekucheka dzine simba guru. Chinonyanya kukosha ndechekuti, maitiro acho anowanzo kunyorova, achishandisa mvura inoyerera nguva dzose kutonhodza waya uye kubvisa guruva regranite, nokudaro kudzivirira kukuvara kwekupisa kwenzvimbo kunogona kukanganisa kugadzikana kwenguva refu kwechinhu chacho. Nzira iyi inobvumirawo Kushanda Nesimba, zvichigonesa kuumbwa kwakarurama kwemabhuroko makuru—anodiwa pamapureti makuru egranite kana mabhesi emuchina—nekudzora kusati kwamboitika, zvichipa geometry chaiyo yekutanga iyo inoderedza zvakanyanya nguva nekurasikirwa kwezvinhu zvinosanganisirwa muzvikamu zvinotevera zvekukuya zvisina kunaka.
Nekutarisa nguva dzose pakusarudza zvinhu zvakanakisa zvakakora uye zvakagadzikana uye kushandisa matekiniki ekucheka epamusoro-soro, anoderedza kushushikana, tinova nechokwadi chekuti chishandiso chega chega cheZHHIMG granite chekuyera chakagadzirwa nehunhu hwechisikigo hunodiwa pakuyera kwakanyatsojeka kwepasi rose. Kubatanidza kwakanyatsojeka kunotevera ingori chiitiko chekupedzisira mukugadzirwa kwakagadzirwa zvakanaka.
