Umbuzo Wokufaka Esikhundleni—Ingabe Amapulatifomu Okubona Ngokucophelela Kwe-Polymer Angathatha Indawo Ye-Granite Ku-Small-Scale Metrology?

Umnotho Wamanga Wokushintshaniswa Kwezinto Ezibonakalayo

Ezweni lokukhiqiza ngokunemba, ukufuna izixazululo ezingabizi kakhulu kuhlala njalo. Ezindaweni zokuhlola ezincane noma eziteshini zokuhlola zasendaweni, umbuzo uvame ukuvela: Ingabe iPlatform yesimanje yePolymer (Plastic) Precision ingayithatha indawo yePlatform yeGranite Precision yendabuko, futhi ingabe ukunemba kwayo kuzohlangabezana nezindinganiso ze-metrology ezidingakalayo?

Kwa-ZHHIMG®, singochwepheshe ezisekelweni ezinembile kakhulu futhi siyaqonda ukuncintisana kobunjiniyela. Nakuba izinto ze-polymer zinikeza izinzuzo ezingenakuphikwa ngesisindo nezindleko, ukuhlaziywa kwethu kuphetha ngokuthi kunoma yiluphi uhlelo lokusebenza oludinga ukuzinza okuqinisekisiwe, okunesilinganiso sesikhathi eside noma ukuthamba kwe-nanometer, ipulasitiki ayikwazi ukuthatha indawo ye-granite enobukhulu obuphezulu.

Ukuzinza Okuyinhloko: Lapho i-Polymer Yehluleka khona Ukuhlolwa Kokunemba

Umehluko phakathi kwe-granite ne-polymer awukona nje ubuningi noma ukubukeka; ulele ezicini zomzimba eziyisisekelo ezingenakuxoxiswana ngazo ukuze kutholakale ukunemba kwebanga le-metrology:

1. Ukwanda Kokushisa (CTE): Lobu ubuthakathaka obukhulu kakhulu bezinto ze-polymer. Amapulasitiki ane-Coefficient of Thermal Expansion (CTE) evame ukuba phezulu ngokuphindwe kayishumi kune-granite. Ngisho nokushintshashintsha okuncane ekushiseni kwegumbi, okuvamile ngaphandle kwamagumbi okuhlanza asezingeni lezempi, kubangela izinguquko ezinkulu, ezisheshayo kupulasitiki. Isibonelo, i-ZHHIMG® Black Granite igcina ukuzinza okumangalisayo, kanti ipulatifomu yepulasitiki izohlala "iphefumula" ngokushintsha kwezinga lokushisa, okwenza izilinganiso ze-sub-micron noma ze-nanometer eziqinisekisiwe zingathembeki.
2. Ukuqhekeka Kwesikhathi Eside (Ukuguga): Ngokungafani ne-granite, efinyelela ukuzinza kokucindezeleka ngenqubo yokuguga yemvelo yenyanga, ama-polymers abonakala sengathi ayacwebezela ngokwemvelo. Abonisa ukuqhekeka okukhulu, okusho ukuthi aguquguquka kancane kancane futhi unomphela ngaphansi kwemithwalo eqhubekayo (ngisho nesisindo senzwa yokukhanya noma i-fixture). Lokhu kuguqulwa okuhlala njalo kuphazamisa ukuthamba kokuqala okuqinisekisiwe emavikini noma ezinyangeni zokusetshenziswa, okudinga ukulinganiswa kabusha okuvamile nokubizayo.
3. Ukudambisa Ukudlidliza: Nakuba amanye amapulasitiki aklanywe ngendlela enikeza izakhiwo ezinhle zokudambisa, ngokuvamile awanakho ukuzinza okukhulu kwe-inertial kanye nokungqubuzana okuphezulu kwangaphakathi kwe-granite enobukhulu obuphezulu. Ukuze kulinganiswe noma kuhlolwe eduze kwemithombo yokudlidliza, ubukhulu be-granite buhlinzeka ngokumuncwa okungcono kokudlidliza kanye nendiza yokubhekisela ethule.

Usayizi Omncane, Izidingo Ezinkulu

Impikiswano yokuthi ipulatifomu "encane" ayithinteki kakhulu kulezi zinkinga inephutha elikhulu. Ekuhlolweni kwezinga elincane, isidingo sokunemba okuhlobene sivame ukuba phezulu. Isigaba esincane sokuhlola singase sinikezelwe ekuhlolweni kwe-microchip noma kuma-optics amahle kakhulu, lapho ibhendi yokubekezelelana iqine kakhulu.

Uma kudingeka ipulatifomu engu-300mm×300mm ukuze kugcinwe ukuthamba kwe-±1 micron, izinto kumele zibe ne-CTE ephansi kakhulu kanye nesilinganiso sokuqhekeka. Yingakho i-Precision Granite ihlala iyisinqumo esiqondile, kungakhathaliseki ukuthi usayizi ungakanani.

Isinqumo se-ZHHIMG®: Khetha Ukuqina Okuqinisekisiwe

Ngemisebenzi engacacile kahle (isb., ukuhlanganiswa okuyisisekelo noma ukuhlolwa komshini okungahleliwe), amapulatifomu e-polymer anganikeza indawo yesikhashana nengabizi kakhulu.

Noma kunjalo, kunoma yiluphi uhlelo lokusebenza lapho:

• Izindinganiso ze-ASME noma ze-DIN kumele zihlangatshezwe.
• Ukubekezelelana kungaphansi kwama-micron angu-5.
• Ukuzinza kobukhulu besikhathi eside akunakuxoxiswana ngakho (isb., umbono womshini, ukuhlelwa kwe-CMM, ukuhlolwa kokubona).

...ukutshalwa kwezimali epulatifomu ye-ZHHIMG® Black Granite kuwukutshalwa kwezimali ekuqinisekiseni ukunemba okulandelekayo. Sikhuthaza onjiniyela ukuthi bakhethe izinto ezisekelwe ekuzinzeni nasekuthembekeni, hhayi nje ekulondolozeni izindleko zokuqala. Inqubo yethu yokukhiqiza eneziQinisekiso Ezine iqinisekisa ukuthi uthola isisekelo esizinzile kakhulu esitholakala emhlabeni jikelele.
