Ezweni lobunjiniyela obunembile kakhulu, ukuphishekela i-micron eyodwa kungasho umehluko phakathi kokuthuthuka nokwehluleka. Sekungamashumi eminyaka, umgogodla wamathuluzi omshini wawuyinsimbi ecijile ngokungenakuphikwa. Kodwa-ke, njengoba izimboni ezifana nokukhiqiza ama-semiconductor, i-aerospace metrology, kanye ne-micro-electronics zicindezela imingcele "yesilinganiso se-nano," ukulinganiselwa kwamafreyimu ensimbi kuye kwabonakala kakhulu. Namuhla,isisekelo somshini we-granite oqondilesekuvele njengendinganiso yegolide kulabo abangenakukwazi ukuyekethisa ekuzinzeni.
Ukukhetha izinto zokwakha ezifanele zohlaka lomshini akuyona nje indaba yezindleko; kuyindaba yefiziksi. Onjiniyela kwa-ZHHIMG bachithe iminyaka behlaziya ukuthi kungani izingxenye zegranite zisebenza kahle kakhulu kunensimbi evamile ezindaweni ezinembe kakhulu.
Ukuzinza Okulinganiselwe Nokucindezeleka Kwangaphakathi: Umbulali Oqondile Othule
Enye yezinzuzo ezibaluleke kakhulu ze-granite ngaphezu kwensimbi ephonswe yizimo zayo eziyisisekelo. Insimbi ephonswe, njengezinto zensimbi, ibhekana nokucindezeleka okukhulu kwangaphakathi ngesikhathi senqubo yokuphonswa nokupholisa. Ngisho nangemva "kokunambitha" noma ukwelashwa ngokushisa, lokhu kucindezeleka kungakhululwa kancane kancane ezinyangeni noma eminyakeni, okuholela ekugobeni okuncane kakhulu. Ku-aisisekelo se-CMM se-granite esinembile, ukukhathazeka okunjalo cishe akukho nhlobo.
I-Granite iyidwala lemvelo eliyi-igneous eliye laguga iminyaka eyizigidi ngaphansi komhlaba. Isakhiwo salo sama-molecule "sikhululekile" ngokwemvelo. Lapho i-ZHHIMG icubungula i-granite eluhlaza ibe uhlaka lomshini, sisebenza ngezinto esezifinyelele isimo sayo sokugcina sokulingana. Kumshini Wokulinganisa Ohlanganisiwe (i-CMM), lokhu kusho ukuthi i-reference plane ihlala iqondile futhi iyiqiniso eminyakeni eminingi yenkonzo, okuqinisekisa ukuthi izilinganiso ezithathwe namuhla zihambisana ngokuphelele nalezo ezithathwe eminyakeni ezayo.
Ukuqonda Indawo Eshisayo
Ukwanda kokushisa kuyisitha sokunemba. Esikhungweni sokukhiqiza esivamile, ukuguquguquka kokushisa akunakugwenywa. Insimbi ephothiwe ine-coefficient ephezulu yokwanda kokushisa (CTE), okusho ukuthi ikhula futhi inciphe kakhulu ngokushintsha kokushisa.
Nokho, i-granite ine-CTE ephansi kakhulu - cishe ingxenye eyodwa kwezintathu kuneyensimbi ephonswe ngensimbi. Uma umshini usebenzisa isisekelo somshini we-granite esinembile, uba buthakathaka kakhulu ekushintsheni kokushisa kwemvelo. Lesi sici sinciphisa isidingo sokuvuselelwa kokushisa okusekelwe kusofthiwe futhi siqinisekisa ukuthi i-geometry yomshini ihlala ingashintshi. Emikhakheni efana nokuhlolwa kwe-semiconductor, lapho izingxenye zizwela ngisho nasekushintsheni okungu-0.1°C, i-granite inikeza "i-inertia" yokushisa insimbi engenakukwazi ukuyifanisa.
Ukudambisa Ukudlidliza: Isihluthulelo Sobuqotho Bomphezulu
Ukunemba akukhona nje ukuhlala unganyakazi; kumayelana nendlela umshini ophatha ngayo ukunyakaza. Yonke injini, i-spindle, kanye ne-actuator kudala ukudlidliza. Uma uhlaka lomshini lungakwazi ukumunca lokhu kudlidliza, kubuyiselwa emuva kuthuluzi noma ku-sensor, okuholela ekuqedweni okungekuhle kwendawo noma umsindo wokulinganisa.
I-granite idlula konke ekucindezeleni ukudlidliza. Isakhiwo sayo sangaphakathi sisebenza kahle kakhulu ekuqedeni amandla e-kinetic kunensimbi ephonswe ngensimbi. Ucwaningo lubonisa ukuthi i-granite inganciphisa ukudlidliza okufika ku-10 ngokushesha kunezinhlaka zensimbi. Ngokusebenzisa isakhiwo se-granite, abakhiqizi bangafinyelela isivinini esiphezulu se-spindle kanye namazinga okuskena okusheshayo kuma-CMM ngaphandle kokulahla ubuqotho bedatha. Isebenza njengesiponji esithule, imunca "umsindo" wenqubo yokukhiqiza.
Ukumelana Nokugqwala Nokuphila Isikhathi Eside
Ezindaweni eziningi zezimboni, umswakama, izinto zokupholisa, kanye nomhwamuko wamakhemikhali kuyizinto ezihlala zisongela imishini. Insimbi ephothiwe idinga ukulungiswa njalo, ukupenda, kanye nokugcoba ngamafutha ukuze kuvinjelwe ukugqwala. Uma ukugqwala kuqala endaweni enembile, ukunemba kuyaphazamiseka unomphela.
I-granite ayiboli ngokwemvelo futhi imelana ne-asidi. Ayigqwali, ayivuthisi, noma isabelane namakhemikhali avamile ezimboni. Lokhu kwenzaisisekelo se-CMM se-granite esinembileilungele amakamelo okuhlanza kanye nezindawo zelebhu lapho inhlanzeko kanye nokuhlanzeka kwezinto kubaluleke kakhulu. Ngaphezu kwalokho, i-granite ayisebenzisi i-magnetic, iqinisekisa ukuthi akukho ukuphazamiseka kwezinzwa ze-elekthronikhi ezizwelayo noma izinto zokusebenza ze-magnetic.
Ukuzibophezela kwe-ZHHIMG ekwenzeni kahle kakhulu
Kwa-ZHHIMG, asigcini nje ngokuthola itshe; sinjiniyela ukunemba. Ukuguquka kusuka ebhulokini eliluhlaza le-gabbro emnyama kuya engxenyeni yomshini ebekezelela kakhulu kuhilela inhlanganisela yomshini we-CNC wesimanje kanye nobuciko basendulo bokugoqa ngesandla. Nakuba imishini ingasisondeza, i-micron yokugcina yokuthamba kwethuizisekelo zomshini we-granite oqondilekuvame ukufezwa ngezandla eziqinile zochwepheshe bethu abangochwepheshe.
Inqubo yethu yokulawula ikhwalithi isebenzisa ama-interferometer e-laser ukuqinisekisa ukuthi yonke imilimitha yesikwele yobuso ihlangabezana nebanga elibekiwe. Kungakhathaliseki ukuthi sikhiqiza isisekelo esikhulu samamitha ayi-6 sesistimu ye-gantry noma ingxenye ekhethekile yebhentshi le-optical, ifilosofi yethu ihlala ifana: isisekelo siyingxenye ebaluleke kakhulu yomshini.
Isiphetho: Ukwakha Ikusasa Nge-Granite
Njengoba isimo sokukhiqiza somhlaba wonke sishintshela ekuzenzekeleni nasekuqondeni okuphezulu, isidingo sezisekelo zemishini ezizinzile, ezithembekile, nezingenakulungiswa sizokhula kuphela. Ngenkathi insimbi ephonswe iyohlala inendawo ekusetshenzisweni kwemishini okunzima, okunomthelela omkhulu, ikusasa le-metrology yobuchwepheshe obuphezulu kanye ne-micro-machining lingelama-granite.
I-ZHHIMG iyaqhubeka nokuhola lolu shintsho, inikeza imakethe yomhlaba wonke izixazululo ze-granite ezichaza umkhawulo ophambili wokuzinza. Ngokukhetha i-granite, onjiniyela abakhethi nje kuphela izinto; bakhetha ifa lokunemba elimelana nokuhlolwa kwesikhathi kanye nokushisa.
