Umbuzo Wokuthatha Indawo—Ingabe Izingxenyekazi Ze-Polymer Precision Precision Ingathatha Indawo YeGranite ku-Small-Scale Metrology?

Umnotho Wamanga Wokushintsha Okubalulekile

Emhlabeni wokukhiqiza okunembayo, ukufuna izisombululo ezibizayo kuhlala njalo. Emabhentshini okuhlola asezingeni elincane noma iziteshi zokuhlola zendawo, umbuzo uvame ukuvela: Ingabe i-Polymer (Plastiki) Precision Platform yesimanje ingathatha indawo ye-Granite Precision Platform yendabuko, futhi ingabe ukunemba kwayo kuzohlangabezana nezindinganiso ezidingekayo ze-metrology?

Kwa-ZHHIMG®, sisebenza ngokukhethekile ezisekelweni ezinembe kakhulu futhi siyaqonda ukuhwebelana kobunjiniyela. Nakuba izinto ze-polymer zinikeza izinzuzo ezingenakuphikwa ngesisindo nezindleko, ukuhlaziya kwethu kuphetha ngokuthi kunoma yisiphi isicelo esidinga ukuqina kobukhulu obuqinisekisiwe, besikhathi eside noma i-nanometer flatness, ipulasitiki ayikwazi ukufaka esikhundleni se-granite ephezulu.

Ukuzinza Okubalulekile: Lapho I-Polymer Yehluleka Ukuhlola Ukunemba

Umehluko phakathi kwe-granite ne-polymer awukona nje ukuminyana noma ukubukeka; ilele ezicini zomzimba ezibalulekile okungaxoxiswana ngazo ngokunemba kwebanga le-metrology:

1. Ukunwetshwa kweThermal (CTE): Lobu ubuthakathaka obubodwa obukhulu bezinto ze-polymer. Amapulastiki ane-Coefficient of Thermal Expansion (CTE) ngokuvamile ephakeme ngokuphindwe kashumi kune-granite. Ngisho nokushintshashintsha okuncane kwezinga lokushisa lasekamelweni, okuvamile ngaphandle kwezindlu ezihlanzekile ezisezingeni lezempi, kubangela izinguquko ezinkulu, ezisheshayo kupulasitiki. Isibonelo, i-ZHHIMG® Black Granite igcina ukuzinza okukhethekile, kuyilapho inkundla yepulasitiki izohlala "iphefumula" ngokushintsha kwezinga lokushisa, okwenza izilinganiso ze-sub-micron noma i-nanometer zingathembeki.
2. I-Long-Term Creep (Ukuguga): Ngokungafani ne-granite, efinyelela ukuzinza kwengcindezi ngenqubo yokuguga yemvelo yezinyanga ezinde, ama-polymers ngokwemvelo ane-viscoelastic. Zibonisa ukunyakaza okubalulekile, okusho ukuthi ziwohloka kancane futhi unomphela ngaphansi kwemithwalo eqhubekayo (ngisho nesisindo senzwa yokubona noma i-fixture). Lokhu kuguga unomphela kulimaza ukucaba okuqinisekisiwe kokuqala phakathi namaviki noma izinyanga zokusetshenziswa, okudinga ukulinganisa kabusha okuvamile nokubizayo.
3. I-Vibration Damping: Ngenkathi amanye amapulasitiki anjiniyela enikeza izakhiwo ezinhle zokudambisa, ngokuvamile awanakho ukuzinza okukhulu kwe-inertial kanye nokungqubuzana okuphezulu kwangaphakathi kwegwadle elinobukhulu obuphezulu. Ngokulinganisa okuguquguqukayo noma ukuhlola eduze nemithombo yokudlidliza, ubuningi begwadle buhlinzeka ngokumuncwa kokudlidliza okuphakeme kanye nendiza eyireferensi ethule.

Usayizi Omncane, Izidingo Ezinkulu

Impikiswano yokuthi inkundla "yosayizi omncane" ayingenwa kalula yilezi zinkinga inamaphutha. Ekuhlolweni kwezinga elincane, imfuneko yokunemba okuhlobene ivamise ukuba phezulu. Isiteji sokuhlola esincane singase sinikezelwe ekuhlolweni kwe-microchip noma ku-ultra-fine optics, lapho ibhendi yokubekezelelana iqine kakhulu.

Uma iplathifomu engu-300mm×300mm idingeka ukuze kugcinwe ukucaba okungu-±1 micron, okokusebenza kufanele kube ne-CTE ephansi kakhulu kanye nezinga lokukhuphuka. Yingakho nje i-Precision Granite ihlala iyinketho eqinisekile, kungakhathaliseki ukuthi ungakanani.

Isinqumo se-ZHHIMG®: Khetha Ukuzinza Okuqinisekisiwe

Ngemisebenzi enembayo ephansi (isb., ukuhlanganisa okuyisisekelo noma ukuhlola komshini), izinkundla ze-polymer zinganikezela ngokuthatha indawo yesikhashana, nengabizi.

Nokho, kunoma yisiphi isicelo lapho:

• Amazinga e-ASME noma e-DIN kufanele ahlangatshezwe.
• Ukubekezelelana kungaphansi kwama-microns angu-5.
• Ukuzinza kwe-dimensional yesikhathi eside akuxoxiswana (isb, ukubona komshini, isiteji se-CMM, ukuhlolwa kokubona).

…ukutshalwa kwezimali kuplathifomu ye-ZHHIMG® Black Granite kuwutshalomali ekunembeni okuqinisekisiwe, okulandelekayo. Sikhuthaza onjiniyela ukuba bakhethe izinto ezisekelwe ekuzinzeni nasekuthembekeni, hhayi nje ukonga izindleko kwasekuqaleni. Inqubo yethu yokukhiqiza ene-Quad-Certified iqinisekisa ukuthi uthola isisekelo esizinzile esitholakala emhlabeni wonke.
