Mu guhitamo ibikoresho by'ubwubatsi bya mashini ikora neza cyane, amahitamo ntabwo ari ukukomera gusa. Ni ukudahindagurika k'ubushyuhe, kudahindagurika kw'ingufu, ubuziranenge bw'igihe kirekire, n'igiciro cyose cyo gutunga. Ibikoresho bitatu byiganjemo ibi: granite karemano, ibumba ryakozwe mu buryo bwa tekiniki, no gucukura amabuye y'agaciro. Buri kimwe gifite umwanya wacyo. Ariko gusobanukirwa aho buri kimwe gihebuje - n'aho kidakomeye - ni itandukaniro riri hagati y'imashini ifite kimwe cya cumi cya mikoroni n'imashini igenda itakaza agaciro mu mwaka umwe.
Ikibazo cy'ubushyuhe buhamye
Ubushyuhe bukabije ni bwo buryo bwo kwica ubuziranenge bucecetse. Imashini yagutse cyangwa igabanye ndetse na mikoroni nke kuri metero imwe kuri dogere selisiyusi bishobora gutuma CMM y'amadolari 500.000 itagira icyo imaze mu kazi gakomeye ko kwihanganira ibintu.
Granite karemano itanga kimwe mu bipimo byo hasi cyane kandi byitezwe by’ubwiyongere bw’ubushyuhe (CTE) mu bikoresho by’ubwubatsi—ubusanzwe iri hagati ya 4.6 na 9 × 10⁻⁶/°C. Ubushyuhe bwayo bukabije ni ubw’akataraboneka: granite ni ibikoresho "bitinda" bihangana gato n’impinduka z’ubushyuhe bw’ikirere, bigatuma iba icyitegererezo cya zahabu kuriimashini zipima hamwen'ibikoresho byo gupima. Muri ZHHIMG®, granite yacu y'umukara ya ZHHIMG® ifite ubucucike bwa ≈3100 kg/m³—iruta granite nyinshi z'umukara zo mu Burayi no muri Amerika—ibi bikaba byongera ubushyuhe n'ingufu zayo.
Ibumba ryakozwe mu buryo bwa tekiniki, cyane cyane silikoni karubide (SiC) na aluminiyumu okiside (Al₂O₃), ritanga agaciro ka CTE kari hasi cyane (3–5 × 10⁻⁶/°C) ndetse n'ubushobozi bwo gutwara ubushyuhe bwinshi (10–30 W/mK ugereranyije na granite ya 1–3 W/mK). Ibi bivuze ko ibumba rishobora gusohora ubushyuhe vuba, ariko biragoye cyane kubikora mu mashini kandi bihenze cyane kubitunganya mu bunini bunini.
Gucukura amabuye y'agaciro (rimwe na rimwe byitwa sima ya polymer cyangwa granite ya epoxy) bifite CTE iri hagati ya 8–12 × 10⁻⁶/°C—iruta granite karemano kandi ntabwo ishoboka bitewe n’ingano ya epoxy resin. Ariko, gucukura amabuye y'agaciro bitanga ubushyuhe bwinshi, birwanya ihindagurika ryihuse ry’ubushyuhe kandi bigatanga ibidukikije bihamye byo gukora CNC mu buryo bukomeye aho moteri zitanga ubushyuhe bwinshi。
Ikintu Gituma Umuntu Agwa
Gutigita ni umwanzi w’irangira ry’ubuso n’uburyo bwo gupima neza. Mu gusya kwa CNC kwihuta cyane, bitera urusaku. Mu igenzura rya semiconductor, ndetse no gutigita kwa mikorosikopi bishobora gutera amakosa yo gupima. Granite karemano ikuraho imitingito inshuro 5-10 neza kurusha icyuma gishongeshejwe. Imiterere yayo ya kristale itanga ubushuhe busanzwe bugabanya urusaku rw’imashini kandi bukongera mu buryo butaziguye irangira ry’ubuso n’ubuzima bw’ibikoresho. Ariko, gutwika amabuye y’agaciro bifata indi ntambwe. Epoxy resin matrix mu gutwika amabuye y’agaciro ifata imitingito neza kurusha imiterere y’amabuye y’agaciro gusa. Hari amakuru avuga ko ubushuhe buruta inshuro 5 kugeza 10 granite karemano, bitewe n’ikigereranyo cya resin-to-aggregate.
Ibinyuranye n'ibyo, ibumba rifite ubushobozi buke bwo kumena amazi—ubusanzwe ikigereranyo cyo kumena amazi kiri hagati ya 0.01 na 0.02 gusa, ugereranije n'ikigereranyo cya granite kiri hagati ya 0.03 na 0.05 na 0.04 na 0.08 cya mineral casting.
Isomo rifatika: Niba ukoresha ibikoresho byinshi byihuta cyane—nk'imashini ikoresha moteri ya PCB cyangwa semiconductor bonder—gukoresha amabuye y'agaciro bishobora kuba amahitamo meza yo kugabanya igihe cyo guhagarara. Niba urimo kubaka ibikoresho bya laboratwari, CMM, cyangwa ibyuma bipima neza aho imiterere y'ibipimo mu myaka myinshi iruta kurenza gutonyanga mu gihe cyo gukata, granite ikomeye ikomeza kuba ibikoresho bikunzwe cyane.
Guhindura imiterere n'imikorere y'inganda
Aha niho ibikoresho bitatu bitandukanye cyane.
Granite iracukurwa hanyuma igasigwa kugira ngo imere neza. Nubwo igera ku burebure bushoboka—ZHHIMG® itunganya granite kugeza ku burebure bungana na nanometero—biragoye gushyiramo ibintu bigoye imbere. Kongeramo imiyoboro cyangwa imiyoboro ikora neza bisaba gucukura no gufatanya cyane. Ubushobozi bwacu bwo gutunganya ibice bimwe bifite uburebure bwa metero 20, ubugari bwa mm 4000, na mm 1000—dukoresheje imashini enye nini cyane za Nantec, buri imwe igura arenga $500.000 USD—bigaragaza ingano ishoboka iyo granite karemano igezweho igezweho.
Gucukura amabuye y'agaciro ni inzira yo gucukura. Ibi bituma habaho "igishushanyo mbonera gihujwe": imiyoboro, imiyoboro, n'imiyoboro y'insinga bishobora gutabwa mu buryo butaziguye mu nyubako. Abashushanya bashobora gukora inyubako zidafite aho ziboshye cyangwa insinga zifatanye n'imigozi zidashoboka gucukura mu ibuye rikomeye. Gucukura ibice byinshi mu gice kimwe cy'ibanze, bigabanya umubare w'imigozi ifatanye—birushaho kunoza ubukomere bw'imashini muri rusange.
Ibumba ritanga ubukana bwinshi cyane (Mohs 8–9.5) kandi rigakomeza kwangirika, ariko gukora bisaba gusya diyama byihariye no gushyushya ubushyuhe buri hejuru ya 1200°C. Ibice bya bumba bisanzwe bifite ubunini buke kandi bihenze cyane.
Umwanzuro
Nta gisubizo kimwe gikwiriye byose. Abakora ibikoresho bikomeye bakunda gukoresha ibikoresho byose uko ari bitatu, bihuye n'ibyo bakoresha aho guhitamo kimwe nk'igipimo ngenderwaho:
- Hitamo granite karemano yo gukoresha kuri platforms za metrology, CMM bases, ubuso butanga umwuka, n'intebe z'urumuri aho mikoroni zo mu kirere mu myaka icumi ari cyo kintu ugerageza gukumira.
- Hitamo gucukura amabuye y'agaciro ku miterere y'ibikoresho by'imashini n'ishingiro by'imiterere bigomba gucukurwa mu buryo bugoye kandi bigafata imivuduko yo gukata.
- Hitamo ibumba rikoreshwa mu gukoresha risaba gukomera cyane, kudasaza, cyangwa gukwirakwira vuba k'ubushyuhe mu buryo buto.
Muri ZHHIMG®, dukora ibintu bitatu byose—granite igezweho, ceramic igezweho, n'ibice bicukura amabuye y'agaciro—kuko tutemera igisubizo cy'ingano imwe. Granite yacu y'umukara ya ZHHIMG®, ifite ubucucike bwa 3100 kg/m³ n'imiterere yayo ihanitse, ikomeje kuba igipimo cy'ikoreshwa aho kudahindagurika cyane bidashoboka kuganirwaho. Ariko kandi twemera ko mineral casting na ceramic bifite umwanya wabyo mu buryo bunoze. Ikintu cy'ingenzi ni ukumenya ibikoresho bikemura ikibazo cyawe cyihariye.
