Muri CNC ibikoresho byo kugenzura imibare, nubwo imiterere yumubiri ya granite itanga urufatiro rwo gutunganya neza-neza, inenge zayo zishobora kugira ingaruka zitandukanye muburyo bwo gutunganya neza, bigaragarira muburyo bukurikira:
1. Ubuso bwubuso mugutunganya buterwa n'uburiganya bwibintu
Imiterere yoroheje ya granite (imbaraga zo kwikuramo cyane ariko imbaraga zidasanzwe, mubisanzwe imbaraga zihindagurika ni 1/10 kugeza 1/20 cyingufu zo kwikuramo) ituma ikunda guhura nibibazo nko gutobora inkombe hamwe na microcrake zo hejuru mugihe cyo gutunganya.
Inenge ya Microscopique igira ingaruka ku ihererekanyabubasha: Iyo ikora neza cyane yo gusya cyangwa gusya, uduce duto ku gikoresho cyo guhuza ibikoresho dushobora gukora ubuso budasanzwe, bigatuma amakosa agororotse yibice byingenzi nka gari ya moshi ziyobora hamwe nakazi ko kwaguka (urugero, uburinganire bwangirika kuva kuri ± 1μm / m kugeza kuri ± 3 ~ 5μm / m). Izi nenge za microscopique zizahita zoherezwa mubice bitunganijwe, cyane cyane mugutunganya ibintu nkibikoresho bya optique hamwe na semiconductor wafer itwara ibintu, bishobora gutuma habaho kwiyongera kwubuso bwibikorwa byakazi (agaciro ka Ra kiyongera kuva kuri 0.1 mm kugeza kuri 0.5μm), bikagira ingaruka kumikorere ya optique cyangwa imikorere yibikoresho.
Ibyago bitavunika bitunguranye mugutunganya imbaraga: Mubihe byo kugabanya umuvuduko mwinshi (nkumuvuduko wa spindle> 15,000 r / min) cyangwa igipimo cyo kugaburira> 20m / min, ibice bya granite birashobora guhura nibice byaho bitewe ningaruka zingaruka zako kanya. Kurugero, iyo ubuyobozi bwa gari ya moshi ihindura icyerekezo byihuse, guturika kumpande birashobora gutuma inzira igenda itandukana ninzira nyigisho, bikaviramo kugabanuka gutunguranye muburyo bwo guhagarara neza (ikosa ryimyanya ryagutse riva kuri ± 2μm rirenga ± 10μm), ndetse biganisha kubikoresho byo kugongana no gusiba.
Icya kabiri, gutakaza imbaraga kwukuri guterwa no kwivuguruza hagati yuburemere no gukomera
Umutungo mwinshi wa granite (ufite ubucucike bwa hafi 2,6 kugeza 3.0g / cm³) urashobora guhagarika kunyeganyega, ariko kandi bizana ibibazo bikurikira:
Imbaraga zidafite imbaraga zitera servo gusubiza inyuma: Imbaraga zidafite imbaraga zatewe nigitanda kiremereye cya granite (nkibitanda binini bya mashini ya gantry bishobora gupima toni icumi) mugihe cyo kwihuta no kwihuta bihatira moteri ya servo gusohora umuriro mwinshi, bikaviramo kwiyongera kwikosa ryikurikiranwa ryikurikirana. Kurugero, muri sisitemu yihuta itwarwa na moteri yumurongo, kuri buri 10% kwiyongera muburemere, imyanya ihagaze irashobora kugabanuka 5% kugeza 8%. By'umwihariko muri nanoscale yo gutunganya ibintu, uku gutinda gushobora gukurura amakosa yo gutunganya ibintu (nk'ikosa ryo kuzenguruka ryiyongera kuva kuri 50nm rikagera kuri 200nm mugihe cya interpolation).
Ubukomezi budahagije butera kunyeganyega gake: Nubwo granite ifite igabanuka ryinshi ryihariye, modulus yayo ya elastike (hafi 60 kugeza 120GPa) iri munsi yicyuma. Iyo uhuye n'imizigo isimburana (nk'imihindagurikire yo gukata imbaraga mugihe cyo gutunganya byinshi-axis ihuza), kwirundanya kwa mikoro bishobora kubaho. Kurugero, mugice cya swing umutwe wibice bitanu-bitunganyirizwamo imashini, ihindagurika rito rya elastike ya granite shingiro irashobora gutuma impande zifatika zifatika zifatika (nkikosa ryerekana ko ryagutse kuva kuri ± 5 "kugeza kuri ± 15"), bikagira ingaruka kumikorere yubuso bugoramye.
Iii. Imipaka yubushyuhe bwumuriro hamwe nubukangurambaga bwibidukikije
Nubwo coefficente yo kwagura ubushyuhe bwa granite (hafi 5 kugeza 9 × 10⁻⁶ / ℃) iri munsi yicyuma cyuma, irashobora gutera amakosa mugutunganya neza:
Ubushyuhe bwa gradients butera ihinduka ryimiterere: Iyo ibikoresho bikora ubudahwema igihe kirekire, amasoko yubushyuhe nka moteri nyamukuru ya shaft hamwe na sisitemu yo gusiga amavuta ya gari ya moshi arashobora gutera ubushyuhe bwikintu mubice bya granite. Kurugero, mugihe itandukaniro ryubushyuhe hagati yubuso bwo hejuru no hepfo yumurimo wakazi ari 2 ℃, birashobora gutera ihinduka hagati ya convex cyangwa hagati ya convex (deflection irashobora kugera kuri 10 kugeza kuri 20 mm), biganisha ku kunanirwa kurwego rwibikorwa byakazi bikomatanya kandi bikagira ingaruka kuri parallelism yo gusya cyangwa gusya (nko kwihanganira ubunini bwibice bya plaque irenga 20 mm).
Ubushuhe bw’ibidukikije butera kwaguka gake: Nubwo igipimo cy’amazi ya granite (0.1% kugeza 0.5%) kiri hasi, iyo gikoreshejwe igihe kinini ahantu hafite ubuhehere bwinshi, urugero rwinshi rwinjira mu mazi rushobora gutuma habaho kwaguka kwa latike, ari nako bitera impinduka muburyo bwiza bwo guhuza gari ya moshi. Kurugero, iyo ubuhehere buzamutse buva kuri 40% RH bukagera kuri 70% RH, urugero rwumurongo wa gari ya moshi ya granite rushobora kwiyongera kuri 0.005 kugeza 0.01mm / m, bigatuma habaho kugabanuka kwubworoherane bwurugendo rwa gari ya moshi igenda no kubaho kwa "gukurura", bigira ingaruka kumirire ya micron.
Iv. Ingaruka zo Gutunganya no Gutunganya Amakosa
Ingorane zo gutunganya granite ni nyinshi (bisaba ibikoresho bya diyama bidasanzwe, kandi gutunganya neza ni 1/3 kugeza 1/2 cyibikoresho byibyuma), bishobora gutuma habaho gutakaza ukuri mubikorwa byo guterana:
Gutunganya ikosa ryo kohereza hejuru yubusabane: Niba haribintu bitandukanijwe (nkuburinganire> 5μm, ikosa ryo gutandukanya umwobo> 10μm) mubice byingenzi nkibiyobora gari ya moshi iyobora hamwe nuyobozo wifashisha imiyoboro, bizatera kugoreka umurongo wa gari ya moshi uyobora nyuma yo kwishyiriraho, kubanziriza imipira yumupira, hanyuma amaherezo biganisha ku kwangirika kwimikorere. Kurugero, mugihe cyo guhuza imirongo itatu-axis, ikosa rya verticalité ryatewe no kugoreka gari ya moshi iyobora irashobora kwagura ikosa ryuburebure bwa diagonal kuva kuri μ 10μm kugeza kuri 50μm.
Ikinyuranyo cyimiterere yimiterere yagabanijwe: Granite yibikoresho binini akenshi ikoresha tekinike yo gutera (nko guteramo ibice byinshi). Niba hari amakosa mato mato (> 10 ") cyangwa hejuru yubuso> Ra0.8μm hejuru yikubitiro, kwibanda kumaganya cyangwa icyuho gishobora kubaho nyuma yo guterana. Munsi yumutwaro muremure, birashobora gutuma habaho kuruhuka muburyo kandi bigatera kugabanuka neza (nko kugabanuka kwa 2 kugeza kuri 5 mm muburyo buri mwaka).
Incamake no guhangana na inspirations
Ingaruka za granite zigira ingaruka zihishe, ziteranya kandi zangiza ibidukikije ku bijyanye n’ibikoresho bya CNC, kandi bigomba gukemurwa mu buryo bwa gahunda binyuze mu guhindura ibintu (nko gutera inda kugira ngo byongere ubukana), kuzamura imiterere (nk'icyuma cya granite ikomatanya), ikoranabuhanga ryo kugenzura ubushyuhe (nko gukonjesha amazi ya mikorobe), hamwe no kwishyurwa kwa lazeri. Mu rwego rwo gutunganya neza nanoscale, birakenewe cyane gukora igenzura ryuzuye riva mubintu byatoranijwe, tekinoroji yo gutunganya kugeza kuri sisitemu yimashini yose kugirango dukoreshe neza ibyiza bya granite mugihe twirinze inenge yabyo.
