Dore ikibazo nkunda kubaza abayobozi b'amaduka atunganya ubuziranenge: ni ryari waherukaga kwizera plaque yawe y'ubuso?
Ntabwo ari “bisa neza.” Ntabwo ari “byanyuze mu igenzura ryinjira.” Ndashaka kuvuga kwizerana — ubwoko bw’ukwizera aho ushyira igice gishya cyakozweho imashini, ugapima ibipimo byawe, kandi ukamenya ko imibare usoma ivuga ku gice, atari ku isahani igenda munsi yacyo.
Abantu benshi barashidikanya. Bamwe bahindura ikiganiro. Bamwe bemeza ko nta cyo bazi, kuko batigeze bagenzura.
Niho iki kiganiro cyose gitangiriye.
Impamvu amasahani yo hejuru agifite agaciro kurusha uko abaguzi benshi babitekereza
Tubayeho mu gihe cy’ibikoresho bipima imirasire ya laser, sisitemu yo kubona, n’ibikoresho byo gukoraho bishobora gupima ibintu bito mu masegonda make. Biroroshye gufata igice cyo hejuru nk'ikintu cy'ibanze - ibuye riremereye (cyangwa igice kinini cy'icyuma gishongeshejwe) kiri mu mfuruka y'icyumba cyo kugenzura ntacyo gikora.
Uretse ko ikora hafi ya byose.
Igishushanyo cy'ubuso ni urwego rw'icyerekezo aho ibipimo byinshi bikorerwa n'intoki n'ibipimo bya kabiri. Buri gipimo cya mikorometero ufata ukoresheje igipimo cy'uburebure, buri gipimo cy'ikizamini, buri kugereranya hagati y'igikoresho cyakozwe n'imashini n'icyitegererezo - byose binyura mu buso igice kirimo. Niba ubwo buso budahamye kandi budashobora gusobanurwa neza mu bushyuhe, buri gipimo cyo hepfo gifite ikosa ritagereranywa.
Ukuri gushimishije ni uko amaduka menshi akoresha igenzura ry’ubuziranenge ku rufatiro rw’ibikoresho bitarigeze bikemangwa mu myaka myinshi ishize. Hari n’igihe mu myaka yashize.
Ibyuma bishongeshejwe vs. Granite: Igereranya nyakuri ntawe ubikora neza
Injira mu nganda icumi zikora ibikoresho by’ikoranabuhanga, uzasangamo ibice bigera kuri 50/50 hagati y’ibyuma bikozwe mu cyuma n’ibikozwe mu cyuma cya granite. Baza abaguzi impamvu bahisemo ibyo bahisemo, kandi inyinshi muri zo zizaguha igisubizo gisa n’icyumvikana ariko kidasubirwaho.
“Nahisemo icyuma gikozwe mu cyuma kuko ari gakondo.”
“Nahisemo granite kuko ihamye kurushaho.”
Ibyo bisubizo byombi ntabwo byuzuye. Dore uko gahunda nyayo y'ibyemezo imeze:
Ibikoresho by'icyuma gikozwe mu cyuma gikozwe mu cyumaBimaze imyaka irenga ijana ari byo bisanzwe mu nganda, kandi kubera impamvu zumvikana. Bifite imiterere myiza yo guhumeka - bikurura imitingito kurusha granite, ikenewe cyane mu mikorere ikomeye. Biroroshye kandi kongera kugaragara iyo byambaye. Umufundi w'umuhanga ashobora gukurura isahani y'icyuma cyashaje ku gipimo cyayo vuba cyane, bigatuma kuyisana byoroha.
Impinduka ni uburyo ubushyuhe bushobora guhindagurika. Ibyuma bishongeshejwe birakura kandi bigatandukana neza bitewe n’impinduka z’ubushyuhe. Isahani y’icyuma ishongeshejwe mu iduka ridafite ubushyuhe mu gihe cy’itumba ikora mu buryo butandukanye n’isahani imwe mu mpeshyi. Ku kazi gasaba ubuziranenge bwa mikoroni mu bipimo binini, ubu buryo bwo kuzenguruka kw’ubushyuhe si ikintu cyoroshye.
Amasahani yo hejuru ya graniteMukemure ikibazo cy'ubushyuhe neza. Granite y'umukara ifite ubushobozi bwo kwaguka kw'ubushyuhe buke cyane kandi ifite ubushobozi bwo kudahinduka mu bushyuhe busanzwe. Isahani ya granite ntikenera uburyo bwo kugenzura ikirere kugira ngo ikomeze imiterere yayo nk'uko icyuma gishongeshejwe kibikora. Nanone ntiyongera ubushyuhe, ntigira ingese, kandi ntisaba amavuta.
Itandukaniro ni uko isanwa ryaba rishoboka. Iyo ubuso bwa granite bushaje cyangwa bwangiritse, ntushobora kubusubirana nk'uko wabishobora ukoresheje icyuma gishongeshejwe. Urimo kureba kongera gukoresha (bihenze kandi bitwara igihe kinini) cyangwa gusimbuza. Niyo mpamvu ubwiza bw'ibikoresho bya mbere n'ubuhanga mu gukora ari ingenzi cyane kuri granite - uba wiyemeje igihe kirekire mu gihe cyo kugura.
Icy'ingenzi mu by'ukuri: ku bikorwa byinshi byo kugenzura ahantu hagenzurwa, ubushyuhe bwa granite butuma irushaho kuba nziza. Ku bijyanye no gukora imashini nini no guteranya ibintu byinshi aho gutigita no gusana ari ingenzi, icyuma gishongeshejwe kiracyahabwa umwanya wacyo.
Uburyo bwo Gutanga Amanota bwasobanuwe: Icyo Mu by'ukuri Urimo Ugura
Ibipimo byinshi by’ibipimo bya plate yo hejuru y’ubutaka byerekeza ku bipimo nka DIN 876, ASME GGGP-463C, cyangwa ISO 8512. Ibipimo bigena amanota y’ubuziranenge — ubusanzwe Icyiciro cya 00, Icyiciro cya 0, Icyiciro cya 1, n’Igice cya 2 — bishingiye ku kwihanganira ubugari.
Dore icyo ayo manota asobanura mu bikorwa, dukoresheje icyitegererezo cya DIN 876 nk'icyitegererezo:
Icyiciro cya 00 cyemerera hafi mikoroni 2.3 zo kunyuranaho hejuru ya mm 1.000. Icyiciro cya 0 cyemerera hafi mikoroni 4.6. Icyiciro cya 1 cyemerera hafi mikoroni 9.2. Icyiciro cya 2 cyemerera hafi mikoroni 18.5.
Iyo miterere yo gukuba kabiri ntabwo ari ikintu gisanzwe - buri ntambwe yo kumanuka mu cyiciro igaragaza gukuba kabiri kw'ikosa ryemewe. Kandi iyo ngengo y'imari y'ikosa ntigomba gutwikira gusa ukwihanganira ubushobozi bwo gukora, ahubwo no kwangirika kw'isahani mu gihe cyo kuyikoresha.
Ku bijyanye n'ibikubiye muri iyi nyandiko: niba upima ibice byakozwe mu mashini kuri mikoroni ± 2, icyuma cyo hejuru cya Grade 1 (mikoroni 9.2 z'ubusumbane bwemewe) kiba kimaze gukoresha hafi 20% by'umubare wose w'ubuhanga bwo kwihanganira ibintu — mbere yo gutekereza ku yindi soko iyo ari yo yose yo gupima idasobanutse. Uwo ni umubare ukwiye kwitabwaho.
Niyo mpamvu laboratwari zikomeye zo gupima ibintu hamwe na sisitemu z’ubuziranenge bw’ikirere hafi ya hose zigena Icyiciro cya 00. Igiciro cy’inyongera cy’icyapa cyo hejuru ni gito ugereranyije n’igiciro cy’ikosa ryo gupima ritabonetse rijya mu gice cy’ibice bidahuye n’imiterere yabyo.
Ni iki cyahitanye isahani yawe ya nyuma (n'ibyo byiza birinda)
Amasahani yo hejuru ntabwo acika intege cyane. Aratemba. Afata ubushuhe. Akora ibyangiritse munsi y'ubutaka bivuye ku bikoresho byaguye. Akora imiterere yo kwambara mu gace runaka bitewe no gukorana kenshi n'ibipimo bimwe.
Uburyo bukunze kugaragara ku byuma bicukurwa mu duce dutose ni uguhinduka kw'ibipimo bitewe n'ubushuhe. Nubwo byashyirwamo amavuta neza, icyuma gicukurwa kiba gifite imyenge ihagije yo kwinjiza umwuka w'amazi uko igihe kigenda gihita, cyane cyane mu bigo bidafite uburyo bwo kugenzura ikirere. Ingaruka ni ukubura buhoro buhoro kw'ubugari bw'amazi, bitagaragara ku cyemezo cyo gupima ariko bikagaragara buri gihe ugerageje kwihanganira ubushuhe.
Amasahani ya granite arangirika mu buryo butandukanye. Ikibazo gikunze kugaragara si ikibazo cy’ubwiza bwa granite - ni ikibazo cy’ihungabana ry’ubushyuhe. Isahani ya granite iri mu bubiko bukonje hanyuma ikajyanwa mu cyumba gishyushye kandi gishyushye cyo kugenzura ishobora kugira ikibazo cyo mu gace runaka kigatera imiyoboro mito mu butaka. Ibi ntibibaho iyo umuntu amenyereye kumenyera neza, ariko mu buzima busanzwe, ibintu byihuta.
Ubundi buryo bwo gucika intege ku bikoresho byombi ni ukwangirika kw'inkurikizi. Imashini ikora mu cyuma cyaguye, ishyirwa ry'agace gakomeye k'icyuma gipima uburebure ritari ryitezwe - ibi bitera uduce duto cyangwa ibimenyetso by'udupira duto biba ibintu bigabanya stress hamwe n'amakosa yo kureba imiterere y'ikirere. Amasafuriya meza yo hejuru aza afite ibikoresho birinda imikorere cyane cyane kugira ngo birinde ibi, kandi abakoresha benshi birengagiza inama kugeza igihe bateze ikibazo.
Urusobe rw'ibinyabuzima nta muntu uvugaho
Isahani yo hejuru iri ku gitereko kitaringaniye ni isahani yo hejuru yangiritse. Igitereko, uburyo bwo kuyishyiraho, n'ibidukikije byose bigira uruhare mu gutuma isahani ikora neza.
Ku byuma bikozwe mu cyuma, uburyo busanzwe ni ugushyiraho akabati gafite ibirenge bingana bishobora guhindurwa. Igitekerezo ni ukugera ku isahani mu minota mike uvuye ku rwego, hanyuma ukareka uburemere bwayo bugakwirakwiza ibisigazwa byose. Ibi bikora neza, ariko bifata ko hasi hakomeye kandi ko idahindagurika iyo hari umutwaro.
Ku masahani ya granite, cyane cyane amasahani manini, imiterere ikomeye kandi ifite inkingi imwe ifite akamaro kurushaho. Granite irakomeye ariko irakomera - ntishobora kwifata neza kugira ngo ifate ubusumbane buke nk'uko icyuma gishongeshejwe kibigenza. Isahani ya granite ishyigikiwe ku musingi utaringaniye izagira ikibazo gitandukanye gishobora gutera gucika, cyane cyane iyo hari ubushyuhe bukabije.
Ibikoresho by'ingenzi mu by'ukuri: ibikoresho byo gutwara ibikoresho byo mu rugo bikoreshwa mu kwirinda kwangirika kw'inkurikizi, ibipfundikizo bikingira imyanda n'ubwandu ku buso bwo gupima, hamwe n'ibyemezo byo gupima buri gihe bivuye muri laboratwari yemewe. Icyapa kidafite icyemezo cyo gupima ubu kirimo gusezeranya ko kidashobora gukomeza.
Gushaka isoko ku mukozi nyawe ugereranije n'umucuruzi wa katalogi
Ibi ni ingenzi cyane kurusha uko abaguzi benshi babibona.
Iyo uguze plaque yo hejuru ku mucuruzi ucuruza ibintu ubikuye mu nganda nyinshi, akenshi ubona ibicuruzwa bifite urupapuro rubigaragaza ariko nta mateka nyayo byakozwemo. Ntuzi uwabikoze, ibikoresho fatizo byakoreshejwe, cyangwa niba uwakoze plaque ya nyuma yari afite uburambe bw'imyaka itatu cyangwa mirongo itatu.
Itandukaniro rigaragara mu miterere y'inkombe, imiterere y'ubuso, no kugumana ubugari bw'igihe kirekire. Isahani y'ubuso iturutse ku ruganda rukora neza rufite uburambe bw'imyaka myinshi mu gukurura intoki izamara igihe kirekire kuko ubuso bwa mbere bwakozwe neza cyane. Isahani iturutse ku mucuruzi w'ibicuruzwa ishobora kuba yujuje ibisabwa mu gihe cyo kuyitanga - ariko nyuma y'amezi atandatu, mu ruganda nyarwo, icyuho kiri hagati yabyo kirapimwa.
Baza umutanga serivisi wawe uti: Ni nde wabikoze? Ni hehe? Nshobora gusura ikigo? Abakora mu biro byawe bafite uburambe bw'imyaka ingahe mu gukata? Ni ubuhe buryo bwo gukurikirana ibintu mu by'ukuri butuma urunigi rwawe rukurikirana ibintu?
Abatanga ibicuruzwa banga gusubiza ibyo bibazo baba bakubwira ikintu.
Guhitamo neza ku busabe bwawe
Icyemezo ntabwo ari icyuma gishongeshejwe cyangwa granite. Ni uguhuza ibikoresho n'urwego n'ibyo ukeneye by'ukuri.
Niba urimo gukoresha laboratwari yo gupima ibidukikije ifite amabwiriza akomeye yo kugenzura ibidukikije n'ibisabwa mu rwego rwa mikoroni: garagaza granite yo mu cyiciro cya 00, ifite ubushobozi bwo gukurikirana ikigo cy'igihugu gishinzwe ibipimo, hamwe n'urugero rw'ubushyuhe n'ubushuhe byanditse.
Niba urimo gukora ahantu hakorerwa imashini zikora ibikoresho biremereye kandi hasi hameze neza: icyuma gikozwe mu cyuma gishyigikiwe neza gifite uburyo bwo kugabanya imihindagurikire gishobora kuba cyiza kurusha granite, kuko uburyo bwo kugabanya imihindagurikire bufite akamaro kanini kuruta ubushyuhe buhamye muri urwo rwego.
Niba uri mu karere k’Amajyepfo y’Uburasirazuba bwa Aziya udafite icyuma gikonjesha mu gace kakorerwamo: kwirinda ubushuhe bwa granite si amahitamo. Ni itandukaniro riri hagati y’isahani ifite imiterere yayo umwaka wose n’iy’imvura igenda ihindagurika buri gihembwe cy’imvura.
Niba uguze sisitemu y’ubuvuzi cyangwa iy’ikirere: saba inyandiko zuzuye zo gukurikirana ibintu, ibyemezo byemewe byo gupima, n’uruganda rufite uburambe muri izo nzego zigenzurwa. Ibipimo by’itangwa ry’amasoko bifite akamaro kimwe n’ibipimo by’ibicuruzwa.
Ibikurikiraho nyuma y'isahani
Dore ikintu abaguzi benshi ba plaque zo hejuru batajya batekerezaho kugeza igihe bigeze: plaque yo hejuru ikora neza nk'uko sisitemu iyikikije ibikora.
Igipimo cy'uburebure bwawe kigomba gupimwa. Ibipimo byawe by'ibizamini bigomba kuba biri mu buryo bwiza bwa mekanike. Imbonerahamwe y'ubushyuhe n'ubushuhe bwawe igomba kuba ijyanye n'igihe. Abatekinisiye bawe bagomba gusobanukirwa uburyo bwo gupima kwaguka k'ubushyuhe mu gihe bapima ibice biri ku bushyuhe butandukanye n'ubwa plaque.
Isahani y'ubuso bwa granite yo mu cyiciro cya 00 ntabwo iguha ibisubizo byo gupima byo mu cyiciro cya 00 mu buryo bwikora. Iguha urwego rw'icyitegererezo rwizewe. Ibindi bice by'urunigi rwo gupima nabyo bigomba kuba byubatswe neza.
Ibyo birakwiye kwibuka ubutaha umuntu azakubaza niba wizeye plaque yawe. Igisubizo gishobora kuba "atari cyo rwose" - kandi igisubizo gishobora gutangirira ku kureba sisitemu yose, atari plaque ubwayo gusa.
Ariko nta gushidikanya ko bitangirana no kugura isahani ikwiye mbere na mbere.
