Isiseko soMatshini weGranite vs. Isiseko seMetal: Kutheni Uzinzo lwezinto lubalulekile kwiZixhobo ezichanekileyo

Nantsi imibuzo abakhi boomatshini abayivayo kubathengi ngalo lonke ixesha:"Ukuba i-linear motor yam ine-nanometer-scale feedback, i-encoder yam ichanekile kwi-sub-micron kwaye i-interferometer yam inokulinganisa nantoni na - kutheni isiseko somatshini sibalulekile?"Impendulo kukuba zonke ezo zinto zichanekileyo zibhekisele kwisiseko. I-linear motor ivelisa amandla obushushu kunye nemagnethi; izikali ze-encoder zifakelwe kwizakhiwo ezikhula kwaye zinciphe; inkqubo yokulinganisa ibika intshukumo enxulumene nesakhelo, hayi "inyaniso". Ukubaisiseko somatshini ochanekileyoiyashukuma, iyangcangcazela okanye iphumle ngaphakathi, i-metrology engcono kakhulu ehlabathini irekhoda nje loo ntshukumo ngokuchanekileyo okukhulu. Isiseko sesona sixhobo somatshini sichaphazela yonke enye — yiyo loo nto ukukhetha izinto kusisigqibo sobunjineli, kungekhona umgca weendleko.

Uzinzo lobushushu

Impazamo yobushushu iseyeyona mthombo mkhulu wempazamo yejiyometri kwiimashini ezichanekileyo, ngokuqhelekileyo ibandakanya i-40–70% yebhajethi iyonke yempazamo kwizixhobo zokulungisa ngokuchanekileyo kunye ne-metrology. I-coefficient yokwandisa ubushushu beGranite imalunga ne-5–6 × 10⁻⁶/°C — malunga nesiqingatha sentsimbi — kwaye, okubaluleke ngokufanayo, igranite ine-conductivity ephantsi yobushushu, ngoko ke utshintsho lobushushu lusasazeka kancinci kwaye i-gradients yakheka kancinci kancinci endaweni yokuba yenzeke ngoko nangoko. Iziseko zentsimbi kunye nezesinyithi eziphosiweyo ziphendula ngokukhawuleza kwi-ambient swings: ukuvulwa kocango lweworkshop, umgca we-coolant, ilanga ngefestile. Oku akuthethi ukuba iziseko zesinyithi azinakusetyenziswa — isiseko sentsimbi esiyilwe kakuhle esinesakhiwo esilinganayo kunye nokupholisa okusebenzayo sinokwenza kakuhle kakhulu — kodwa umakhi womatshini kufuneka alawule ngokukhutheleyo oko igranite ikumelana nako ngokungakhathaliyo.

Ukudambisa ukungcangcazela

Ulwakhiwo lwangaphakathi lwe-crystalline ye-granite luchitha amandla okungcangcazela ngokukhawuleza ngokuphindwe kalishumi kunentsimbi. Kwizixhobo ezinee-linear motors, ii-high-speed scanning probes okanye i-femtosecond laser optics, ukudambisa kumisela ukuba ukuphazamiseka kuyabola kwi-milliseconds okanye kuyaqhubeka njengemiphetho engacacanga kunye nokulinganisa okungxolayo. Isinyithi esibunjiweyo sinokwakhiwa ngeembambo kunye nemingxuma egcwalisiweyo ukuze ifume kakuhle, kodwa ukusebenza kwayo kuxhomekeke kwisakhono soyilo kunye nobukhulu bodonga.isiseko somatshini wegraniteinika ukufuma okuphezulu ngokwendalo yezinto ezibonakalayo, ngaphandle kwejometri — inzuzo ebalulekileyo xa isakhiwo kufuneka sivuleke, sincinci okanye sifakwe nzulu ukuze sihambise iintambo kunye nokuhamba eqongeni.

Uzinzo Lwemilinganiselo Ngokuhamba Kwexesha

Ii-cast iron cast castings kunye neefreyimu zentsimbi ezidityanisiweyo zithwala uxinzelelo olushiyekileyo oluvela kwi-cast, i-welding kunye ne-machining enzima. Kwiinyanga neminyaka, olu xinzelelo luyaphumla kwaye isakhiwo siyashukuma - ngokuqhelekileyo ii-micrometer ezimbalwa, ngamanye amaxesha ngaphezulu emva kokuthutha okurhabaxa okanye ukutshayiswa kobushushu. Yiyo loo nto iziseko zesinyithi zifuna unyango lobushushu olunciphisa uxinzelelo kwaye zihlala ixesha "lokuzinza" ngaphambi kokulinganiswa kokugqibela. I-Granite, eyenziwe kwiminyaka engamakhulu ezigidi kwaye yambiwa kwiibhloko ezinkulu, ayinaxinzelelo olushiyekileyo olubangelwa kukwenziwa ukuze iphumle: yakuba idibene, i-geometry yayo iyahlala.izinto zegraniteezilinganisiweyo namhlanje ziqinisekiswa kwakhona rhoqo emva kweminyaka embalwa kakhulu kunendlela ezazinyamezele ngayo ekuqaleni.

Ukumelana nokugqwala kunye nokuziphatha kweMagnetic

I-Granite ayibolisi: inkungu epholisayo, ulwelo olusikiweyo kunye nomoya ofumileyo ayizichaphazeli, ngoko ke akufuneki zigqubuthelo zokukhusela okanye iifilimu zeoyile - inzuzo yokwenyani kumagumbi okucoca e-semiconductor apho ukuphuma kwegesi kunye nokuveliswa kwamasuntswana kulawulwa ngokuqinileyo. I-Granite ikwabo ...

Uthelekiso olusecaleni

Imbono Enyanisekileyo Yobunjineli: I-Metal Isasebenza Nini?

I-Granite ayisosimpendulo sichanekileyo ngokuzenzekelayo, kwaye umthengisi othembekileyo ngobuchwephesha uya kutsho njalo. Isinyithi siyaphumelela xa isiseko kufuneka sibe sikhulu kakhulu kodwa sibe sikhaphukhaphu, xa kufuneka iimilo ezintsonkothileyo ezenziweyo okanye iindonga ezibhityileyo, okanye xa uxinzelelo lweendleko luphezulu kwaye imfuneko yokuchaneka incinci. Uyilo lwe-hybrid luqheleke kakhulu kwaye ludla ngokuba lolona lungelelwaniso lubalaseleyo lobunjineli: isakhelo sentsimbi esitshisiweyo esiphethe umphezulu wereferensi ye-granite echanekileyo, izakhiwo ze-mineral-cast ezibotshelelwe kwiireyile ze-granite, okanye iintsika ze-granite ezibotshelelwe kwiifreyimu zentsimbi ezimanzi. Umbuzo ochanekileyo awungowokuba "i-granite okanye isinyithi?" kodwa"yeyiphi ipropati - ubushushu, ukufuma, uzinzo - ethintela ukuchaneka kwalo matshini, kwaye yeyiphi impahla ewuzisa ngobunzima obamkelekileyo kunye nexabiso elifanelekileyo?"

Oko Ubuchule Bokwakheka Okukhulu Bukwenza Kube nokwenzeka

Ithiyori yezinto ezibonakalayo iba yinyani kuphela xa umenzi ekwazi ukuvelisa isiseko esifunekayo kumatshini wakho. Ukwenziwa kwegranite echanekileyo kwinqanaba lemizi-mveliso kuchazwa ziindlela ezimbalwa zokulinganisa: umatshini wokugaya i-singleiziseko zegraniteukuya kuthi ga kwiitoni ezili-100, ubude bomatshini bufikelela kwi-20 m, ububanzi bufikelela kwi-4000 mm kunye nobukhulu bufikelela kwi-1000 mm, kunye nobukhulu bomphezulu obukhulu obufikelela kwi-6000 mm. Le mida imisela ukuba isiseko se-lithography-stage, itafile ye-CMM epheleleyo okanye isiseko se-laser-gantry singenziwa njenge-monolith enye engenaxinzelelo — endaweni yokudibanisa kwiziqwenga ezincinci ezinamalungu aba ngamaqondo ashushu kwaye athomalalisa ubuthathaka. Xa uvavanya nayiphi naumthengisi wegranite ochanekileyo, cela i-envelope yokwenyani yesixhobo somatshini kunye nokungaqiniseki kokuhlolwa kwesixhobo sabo esikhulu sokugaya, kungekuphela nje ukunyamezelana kwencwadana kwipleyiti ye-500 mm.

Isiphelo: Uzinzo lusisiseko somatshini wonke

Iimoto ezizii-linear motors, ii-encoders kunye nee-interferometers zilinganisa kwaye zibuyisela — kodwa zinokubuyisela kuphela iimpazamo ezaziwa yinkqubo yolawulo, ezibhekisele kwisiseko esihlala sihleli. Uzinzo lobushushu lweGranite, ukuxinana kwangaphakathi, ukhuseleko lokugqwala kunye nokukhululeka kuxinzelelo olushiyekileyo kwenza ukuba ibe zizinto ezibhekisa kwiziseko zoomatshini abachanekileyo kwi-metrology, semiconductor kunye nezixhobo ze-laser; izakhiwo zesinyithi kunye ne-hybrid ezenziwe ngokufanelekileyo zihlala zisebenza apho ubunzima, imo okanye ixabiso lilawula khona. Ukuphumelela kobunjineli kuvela ekuhambelaniseni iipropati zezinto kunye nohlahlo lwabiwo-mali lweempazamo zomatshini — kunye nokukhetha umenzi onobuchule obukhulu obuqinisekisiweyo bokuhambisa ezo zinto ngobukhulu obufunekayo kumatshini wakho.
