Nk'igikoresho cy'ingenzi cyo gupima mu buryo bunonosoye, Granite CMM Platform (izwi kandi nka marble coordinate measurement machine table, precision granite measurement table) izwi cyane kubera uburyo ihamye kandi ikora neza. Icyitonderwa: Rimwe na rimwe ishyirwa mu byiciro bitari byo hamwe na platform za CMM z'icyuma gishongeshejwe ku isoko, ariko imiterere karemano y'amabuye y'agaciro ya granite iha inyungu zidasimburwa mu buryo bwo gupima neza cyane - itandukaniro rikomeye ku banyamwuga bashaka ibipimo byizewe byo gupima.
1. Ibisobanuro by'ingenzi n'ikoreshwa ry'ibanze
Platifomu ya CMM ya granite ni igikoresho cyo gupima neza cyakozwe mu mabuye karemano yo mu rwego rwo hejuru, cyakozwe binyuze mu gutunganya no kurangiza hakoreshejwe intoki bya CNC. Ikoreshwa ryayo ry'ibanze rikubiyemo:
- Ikora nk'urwego rw'ibanze rw'imikorere y'imashini zipima (CMM), bigatuma habaho igenzura ry'ibice by'imashini neza.
- Gushyigikira igeragezwa ry’ibikoresho by’imashini neza, kugenzura ubuziranenge bw’imiterere y’imashini (urugero: ubugari, ubugari) bw’ibikoresho by’imashini.
- Gukora isuzuma ry’ibipimo by’ubuziranenge n’isesengura ry’impinduka mu bice by’ingenzi (urugero: ibice by’indege, ibice by’imodoka by’ubuziranenge).
- Ifite ibimenyetso bitatu by’ingenzi ku buso bwayo bw’akazi, byoroshya gupima no gushyira mu mwanya wa CMM probes kugira ngo ikore neza mu gupima.
2. Ibigize amabuye y'agaciro n'akamaro k'imikorere karemano
2.1 Ibigize amabuye y'agaciro by'ingenzi
Imbuga za granite nziza cyane zigizwe ahanini na:
- Pyroxene (35-45%): Yongera ubucucike bw'imiterere n'ubudasaza.
- Plagioclase feldspar (25-35%): Ituma imiterere isa kandi ubushyuhe buke bugabanuka.
- Imyunyu ngugu (olivine, biotite, magnetite): Igira uruhare mu gutuma ibintu birushaho kuba umukara kandi bigakomeza kurwanya imbaraga za rukuruzi.
Nyuma y’imyaka amagana na miliyoni y’ubusaza karemano, imbaraga z’imbere z’iyo granite zirarekurwa byuzuye, bigatuma habaho imiterere ihamye ya kristu ikuraho imihindagurikire y’inyuma yo gutunganya—akarusho kadasanzwe ugereranyije n’ibikoresho byakozwe n’abantu.
2.2 Ibyiza bya tekiniki
Ugereranije n'ibyuma bikozwe mu cyuma cyangwa ibikoresho bivanze, ibyuma bikozwe mu cyuma cya granite CMM bitanga umusaruro udasanzwe:
- Ituze ridasanzwe: Nta stress y'imbere iterwa no gusaza karemano ituma nta guhindagurika kw'ibipimo mu gihe kirekire cyangwa mu gihe kirekire (kugeza kuri 500kg/m² ku bikoresho bisanzwe).
- Ubukomere Bukomeye no Kudashira: Ubukomere bwa Mohs bwa 6-7 (burenze icyuma cya cast 4-5), butuma ubuso bushira buhoro nubwo bwaba burengeje ukwezi kwa 10.000.
- Kurwanya kwangirika no kwangirika: Ntishobora kwangizwa na aside, alkali, n'ibintu bishongesha mu nganda; imiterere idakoresha ingufu za rukuruzi yirinda kubangamira ibikoresho bipima neza ingufu za rukuruzi.
- Kwaguka k'ubushyuhe buke: Igipimo cyo kwaguka k'umurongo cya 5.5×10⁻⁶/℃ (1/3 cy'icyuma gishongeshejwe), bigabanya ihindagurika ry'ibipimo riterwa n'ihindagurika ry'ubushyuhe bw'ikirere.
- Gusana Guke: Ubuso bworoshye kandi bunini (Ra ≤ 0.4μm) ntibusaba imiti idatera ingese cyangwa amavuta asanzwe; guhanagura byoroshye ukoresheje igitambaro kitagira umugozi bikomeza isuku.
3. Ibipimo by'Uburyo Bwiza n'Ibipimo by'Ubuhanga bwo Kwihanganira
Uburyo bwo kwihanganira ubugari bw'imbuga za granite CMM bukurikiza cyane ibipimo ngenderwaho bya GB/T 4987-2019 (bingana na ISO 8512-1) kandi bugabanyijwemo amanota ane y'ubuziranenge. Uburyo bwo kwihanganira ubugari bw'imbuga bukurikira (D = uburebure bw'ubuso bukora, muri mm; ubushyuhe bwo gupima: 21±2℃):
- Icyiciro cya 000 (Uburyo bworoshye cyane): Ubwihangane = 1 × (1 + D / 1000) μm (bikwiriye CMM zifite ubuziranenge bwinshi cyane mu bidukikije bya laboratwari).
- Icyiciro cya 00 (Ubuhanga bwo hejuru): Ubushobozi bwo kwihanganira = 2 × (1 + D / 1000) μm (ni byiza cyane ku bikoresho bya CMM byo mu rwego rw'inganda mu gukora imodoka/ikirere).
- Icyiciro cya 0 (Uburyo bwiza): Ubwihangane = 4 × (1 + D / 1000) μm (ikoreshwa mu gupima ibikoresho by'imashini rusange no kugenzura ibice byabyo).
- Icyiciro cya 1 (Isanzwe): Ubwihangane = 8×(1 + D/1000) μm (bikoreshwa mu kugenzura ubuziranenge bw'imashini).
Imbuga zose za granite ZIDASANZWE zigenzurwa n’abandi, hagatangwa raporo y’ubuziranenge bushoboka kuri buri gice—igenzura ko ubuziranenge bwubahirizwa ku rwego mpuzamahanga.
4. Ibisabwa ku buso bw'akazi n'imbogamizi
4.1 Ibipimo ngenderwaho by'ubuziranenge ku buso bw'akazi
Kugira ngo harebwe ko ibipimo ari ukuri, ubuso bw'imikorere bwa granite CMM platforms bugomba kuba budafite inenge zigira ingaruka ku mikorere, harimo:
- Umwobo w'umucanga, umwobo ugabanuka, imiturire, cyangwa ibintu biyigize (bitera ikwirakwira ry'imbaraga ritaringaniye).
- Imivurungano, gushwanyagurika, cyangwa ibizinga by'ingese (bihindura ingingo z'ibipimo).
- Ubushobozi bwo gupfundika cyangwa imiterere idahuye (bituma habaho kwangirika gutandukanye).
Ubuso budakora (urugero, impande zo ku ruhande) bwemerera gusana umwuga utudomo duto cyangwa inenge z'udusimba, mu gihe bitagize ingaruka ku miterere y'inyubako.
4.2 Inzitizi za tekiniki n'igabanya ry'ingaruka
Nubwo platifomu za granite ari nziza cyane mu buziranenge, zifite imbogamizi zihariye abahanga bagomba kuzirikana:
- Ubuhanga bwo kugabanya ingaruka: Ntishobora kwihanganira ingaruka zikomeye (urugero, ibice by'icyuma bigwa); ingaruka zishobora gutera uduce duto tw'imbobo (nubwo atari uduce duto, ibyo bikaba birinda kugira ingaruka ku buryo buboneye bwo gupima).
- Ubushuhe: Igipimo cyo kwinjiza amazi ni ~1%; igihe kirekire umuntu ahura n'ubushuhe bwinshi (>60%) bishobora gutera impinduka nke mu ngero. Kugabanya ubushuhe: Shyiraho irangi ryabugenewe rikozwe muri silicone ritaziba amazi (ritangwa ku buntu hamwe n'amabwiriza ATAGERWAHO).
5. Kuki wahitamo Platforme za Granite CMM ZIDASANZWE?
- Gushakisha ibikoresho: Dukoresha granite ya "Jinan Black" gusa (ifite ubuziranenge buri munsi ya 0.1% by'umwanda), ituma imiterere yayo ingana kandi ikagira imikorere ihamye.
- Uburyo bwo gusya neza: Uburyo bwo gusya CNC (kwihanganira ± 0.5μm) hamwe no gusya intoki (Ra ≤ 0.2μm) birengeje urugero rw'inganda.
- Guhindura: Dutanga ingano zidasanzwe (kuva kuri 300 × 300 mm kugeza kuri 3000 × 2000 mm) n'ibishushanyo byihariye (urugero: imiyoboro ya T-slot, imyobo ifite imigozi) kugira ngo bihuze na moderi yawe ya CMM.
- Inkunga nyuma yo kugurisha: garanti y'imyaka 2, kongera gusuzuma neza buri mwaka ku buntu, no kubungabunga ahantu hose (hakorerwa i Burayi, Amerika ya Ruguru, na Aziya y'Amajyepfo y'Uburasirazuba).
