Ibyiza byo gukoresha ibyuma bipima neza bya granite mu mashini eshatu.

Mu rwego rw'inganda, imashini ipima ibice bitatu (CMM) ni igikoresho cy'ingenzi cyo kugera ku igenzura ryimbitse ry'ibipimo n'isuzuma ry'uburyo ihagaze n'aho iherereye, kandi ukuri kwayo mu gupima bigira ingaruka ku ireme ry'ibicuruzwa. Imbuga za granite zipima neza, hamwe n'imikorere yazo myiza, zabaye amahitamo meza ku mashini zipima ibice bitatu, zitanga garanti yizewe yo kumenya neza.
1. Ubuhanga n'ubudahangarwa byo hejuru cyane
Platifomu za granite zifite ubushobozi bwo kudahinduka mu buryo butangaje kandi zifite ubushobozi bwo kwaguka mu buryo buciriritse cyane, ari na (4-8) × 10⁻⁶/℃ gusa. Mu nganda zigoye kandi zihindagurika, nubwo ubushyuhe bwahinduka, impinduka mu buryo bukabije mu buryo busanzwe ni nto cyane, birinda amakosa yo gupima aterwa no guhinduka k'ubushyuhe. Hagati aho, imiterere y'imbere ya granite ni nini cyane. Nyuma y'imyaka miriyari y'ibikorwa bya geologi, stress y'imbere yakuweho mu buryo busanzwe, kandi nta guhinduka k'ubusaza kuzabaho. Ibi byemeza ko ikigereranyo cyo gupima kizakomeza kurangwa no kudahinduka mu buryo burambye kandi bigakomeza kuba ubushishozi mu gushyiramo no gusubiramo ubushishozi mu gushyiraho imashini ipima ibintu bitatu ku rwego rwo hejuru igihe cyose.

Icya kabiri, imikorere myiza yo kurwanya kunyeganyega no kudakomeza
Gutemba kw'ibikoresho by'imashini no gutangira no guhagarara kw'ibikoresho mu icupa ry'umusaruro bishobora kubangamira uburyo bwo kumenya neza imashini ipima ibintu bitatu. Granite ifite ubushobozi bwiza bwo gutemba, ifite igipimo cyo gutemba kingana na 0.05-0.1, gishobora kugabanya vuba ingufu z'intege nke zo hanze. Iyo intege nke zoherejwe kuri platform, granite ishobora guhagarika intege nke mu gihe gito, ikagabanya ingaruka zo gutemba mu gihe cyo gupima, ikemeza ko hagati y'icyuma gipima n'ubuso bw'aho bikora ibintu bihurira, kandi bigatuma amakuru yo gupima aba nyayo kandi yizewe.
Itatu. Ubukomere bwinshi no kudashira kw'ingufu
Granite ifite ubukana bwa 6 kugeza kuri 7 ku gipimo cya Mohs, ubucucike buri hagati ya 2.7 na 3.1g / cm³, kandi irwanya kwangirika kw'ubuso neza. Mu gihe kirekire ikoreshwa n'imashini ipima ibice bitatu, gupakira no gupakurura ibikoresho byo gukoraho kenshi no kugenda kw'ibikoresho byo gupima ntibikunze gutera kwangirika ku buso bw'urukuta rwa granite. Nubwo nyuma y'imyaka myinshi ikoreshwa, ubuso bw'urukuta bushobora kugumana ubugari bwiza kandi bunoze, bikanongera ubuzima bwiza bwo gukora neza bw'imashini ipima ibice bitatu no kugabanya ikiguzi cyo kubungabunga ibikoresho.
Icya kane, ubuziranenge bukomeye bw'ibinyabutabire
Mu nganda zikora ibintu bitandukanye, akenshi hari ibintu bya shimi nk'ibica amazi n'amavuta yo kwisiga, kandi bimwe bishobora no kuba biherekezwa n'imyuka yangiza. Granite ifite imiterere ihamye ya shimi, ifite ubushobozi bwo kwihanganira pH (1-14), ishobora kurwanya kwangirika kw'ibintu bisanzwe bya shimi, kandi ntikunda kwangirika cyangwa kwangirika. Iyi miterere ntirinda gusa urubuga ubwarwo ahubwo inatuma icyuma gipima ibintu bitatu gikorera ahantu heza, ikarinda ko ibikoresho bipimwa neza kandi ubuzima bwabyo bugaterwa n'umwanda wa shimi.
Imbuga za granite zipima neza, zifite ibyiza byo gukora neza cyane, kudahindagurika cyane, kudahindagurika cyane, kudashira no kudahindagurika mu mikorere y’ibinyabutabire, zitanga ishingiro rikomeye ryo kumenya neza imashini zipima ibintu bitatu kandi zigira uruhare rudasimburwa mu kugenzura ubuziranenge bw’inganda zigezweho zipima neza.
