Precision motion mechanisms ua lub luag haujlwm tseem ceeb hauv cov txheej txheem tshuaj xyuas semiconductor, linear motor XY worktables, laser ua cov cuab yeej thiab tswj cov tshuab ntsuas. Txhawm rau ua tiav micron lossis txawm nanometer- theem rov ua haujlwm thiab siab - nrawm nrawm nrawm rau kev ua tiav cov txheej txheem, nws tsis txaus los tso siab rau kev ua tau zoo ntawm cov lus qhia, gratings thiab tsav modules. Lub rigidity ntawm lub hauv paus nqa tag nrho cov lus tsa suab yog lub hauv paus ntsiab lus uas txiav txim siab lub siab txwv ntawm qhov tseeb dynamic. High-rigidity precision granite Cheebtsam ua raws li qhov tseem ceeb ntawm cov kabmob substrates rau cov txheej txheem kev ua haujlwm zoo li no, xa cov kev txhawb nqa ruaj khov thiab txhim khu kev qha rau siab - nrawm thiab siab - zaus reciprocating motion.
Rigidity yog hais txog lub peev xwm ntawm cov qauv los tiv thaiv deformation. Thaum cov hlau hauv paus pib sai sai- nres thiab thim rov qab ceev ceev hauv siab - nrawm nrawm, me elastic deflection yuav tshwm sim vim tsis txaus rigidity. Xws li instantaneous deformation yog pom tsis tau ntawm qhov muag liab qab, tsis tau nws ncaj qha amplifies positioning yuam kev. Tshwj xeeb tshaj yog nyob rau hauv ntev - mus txawv tebchaws thiab siab - zaus dynamic motion scenarios, lub tsub zuj zuj ntawm rov deformation ua rau raug drift thiab tsis muaj zog qhov rov qab positioning stability ntawm cov khoom. In contrast, high-rigidity granite substrates feature dense crystals and a uniform internal structure with excellent elastic modulus. Lub deformation nyob rau hauv sab nraud load yog tsawg heev. Thaum linear motors thiab qhia rail sliders reciprocate ntawm kev kub ceev ntawm lub worktable, lub hauv paus granite muaj peev xwm tswj tau instantaneous dabtsi yog khoov thiab torsional deformation, kom ntseeg tau tias cov ncaj ntawm cov kev taw qhia rail benchmark tseem unchanged thaum lub sij hawm mechanism txav.
Sib nrug los ntawm cov kabmob static rigidity, siab rigidity ntawm granite ua haujlwm ua ke nrog nws cov khoom damping. Thaum lub sij hawm acceleration thiab deceleration, precision motion mechanisms tsim kev vibration thiab resonance nyiam. Ordinary hlau puag yog nquag resonance nrog qeeb vibration attenuation. Cov neeg ua haujlwm yuav tsum tau tos ntev rau kev ruaj khov, txo cov khoom siv lub voj voog ua haujlwm. Lub siab -rigidity granite matrix los nrog superior sab hauv damping. Nws sai sai absorbs cuam tshuam kev co uas tsim los ntawm cov lus tsa suab mechanisms thiab shortens lub vibration lwj lub sij hawm. Tom qab lub tshuab ua tiav qhov chaw, qhov chaw ua haujlwm tuaj yeem rov qab mus rau lub xeev ruaj khov yam tsis muaj lub sijhawm tos ntev rau kev vibration dissipation. Qhov no txhim kho cov cuab yeej kev khiav hauj lwm zoo thiab kev ntsuas qhov tseeb, zoo kawg nkaus txuam siab -xav tau kev siv dynamic xws li femtosecond laser ua, semiconductor wafer tshuaj xyuas thiab perovskite txheej.
Rau qhov ntev ntev - mus txawv tebchaws precision motion khoom, qhov zoo ntawm siab - rigidity integrated granite Cheebtsam ua qhov tseem ceeb. Loj -span motion platforms txais yuav cov hlau spliced lossis me me phua hauv paus raug kev txom nyem tsis muaj zog ntawm cov pob qij txha thiab cov khoom thauj tsis sib xws, uas yooj yim ua rau cov txheej txheem deformation thaum txav mus los. Integrated granite txaj tuaj yeem tsim tau raws li cov khoom loj monolithic yam tsis muaj qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Cov txheej txheem ua tiav ntawm cov lus qhia thiab cov kab hluav taws xob cov kab hluav taws xob tau sib sau ua ke ncaj qha rau ntawm qhov sib xyaw granite siv nto, yog li cov khoom thauj tuaj yeem sib npaug mus rau tag nrho lub hauv paus thiab kev sib txawv ntawm qhov tshwm sim los ntawm ib nrab tsis txaus rigidity tuaj yeem zam tau. Meanwhile, mounting siv qhov chaw rau kev taw qhia rails, huab cua passages, T-slots thiab positioning qhov yuav tsum tau prefabricated raws li tus tsim yuav tsum tau ntawm cov lus tsa suab mechanisms, kom ntseeg tau tias sib xws ntawm mounting benchmarks thiab cov lus tsa suab benchmarks.
Lub sijhawm ntev - qhov tseeb ntawm qhov siab -rigidity granite bases kuj lav ruaj khov ntev - lub sijhawm ua haujlwm ntawm precision motion mechanisms. Nyob rau hauv cyclic loads coj los ntawm kev nruam reciprocating tsab ntawv tsa suab, qee cov ntaub ntawv yuav nkag mus thiab ua rau qeeb tus qauv offset. Kev ntxhov siab tag nrho-relieved granite substrates khav theeb muaj zog creep tsis kam. Lawv cov qauv thiab cov ntaub ntawv saum npoo yuav tsis deform maj mam nyob rau hauv ntev - lub sij hawm cyclic loads. Ua ke nrog nanoscale lapping thev naus laus zis, qhov siv qhov chaw tuaj yeem tswj tau qhov tiaj tus rau lub sijhawm ntev thiab txo qhov zaus ntawm kev rov ua dua tshiab rau cov txheej txheem kev txav. Tsis tas li ntawd, cov khoom siv tsis yog{10}} sib nqus thiab tiv taus cov roj me me thiab cov dej noo hauv cov chaw ua haujlwm. Nws cov rigidity thiab benchmark precision yuav nyob ruaj khov rau ib ntev lub sij hawm nyob rau hauv complex ib puag ncig xws li semiconductor cleanrooms thiab precision optical ntau lawm kab.
Txawm li cas los xij, siab rigidity tsis txhais hais tias tiv thaiv kev ua phem. Granite kuj nkig. Thaum lub sij hawm hoisting thiab sib sau ua ke ntawm cov lus tsa suab, cov ntsiab lus txhawb nqa yuav tsum tau npaj kom tsim nyog thiab bolt preload yuav tsum tau tswj kom tsis txhob muaj pob zeb puas los ntawm cov khoom siv hauv zos. Yog tias ua haujlwm raws li cov lus qhia tshwj xeeb ntawm kev sib dhos, qhov siab -rigidity zoo ntawm granite hauv paus tuaj yeem ua haujlwm siab los txhawb nqa tag nrho cov lus tsa suab.
Lub dynamic qhov tseeb ntawm precision motion mechanisms pib los ntawm rigidity kev ua tau zoo ntawm lub hauv paus. Featuring siab elastic modulus, zoo heev deformation kuj, ntuj vibration damping thiab qis creep, siab -rigidity precision granite Cheebtsam zoo tswj deflection thiab vibration induced los ntawm siab - ceev txav thiab ua kom cov kev taw qhia rail benchmark ruaj khov. Lawv tsim lub hauv paus txhawb zog rau ntau yam ntev - mus txawv tebchaws, siab -acceleration precision motion platforms thiab pab ultra- cov cuab yeej precision ua tiav ruaj khov thiab siab -precision dynamic ua haujlwm.
