Ukuphoswa kwegranite kunye neeminerali kusombulula uninzi lweengxaki zozinzo kuyilo loomatshini oluchanekileyo, kodwa kukho udidi lwesicelo apho kungekho nanye ifanelekileyo, kwaye iinjineli zifikelela kwi-ceramic yobugcisa endaweni yoko - ngokuqhelekileyo izinto ezisekwe kwi-alumina okanye kwi-zirconia.
Isizathu sibangelwa bukuqina okuthile kunye nokumelana nokuguguleka endaweni yokuziphatha kobushushu. I-granite izinzile ngokwemilinganiselo kodwa ithambile kwaye iyaphuka phantsi komthwalo ophantsi; isuntswana eliqinileyo libambeke phakathi kwe-umphezulu wegranitekwaye icandelo elihambayo linokuyikrwela okanye liyiqhekeze. Iiceramics ezichanekileyo, xa kuthelekiswa, zinobunzima obuphakathi kwe-1,200-1,500 HV — ngaphezulu kakhulu kwentsimbi yesixhobo esiqinileyo — ngelixa zigcina i-coefficient yokwanda kobushushu edla ngokuba ngaphantsi kune-granite. Loo mxube wobunzima, i-CTE ephantsi, kunye nokungangeni kweekhemikhali yingakho iiceramics zibonakala ngokukodwa kwiindawo zomatshini ezidibana noqhagamshelwano oluphindaphindwayo okanye iindawo ezixineneyo: ii-spindles ezithwala umoya, ii-guideway rails ezixhomekeke kuqhagamshelwano oluhlala lutyibilika, kunye nezixhobo ezisetyenziswa ngaphakathi kwe-vacuum okanye ii-corrosive process chambers kwimveliso ye-semiconductor.
Akukho mntu uthetha ngokwaneleyo malunga nobunzima
Izinto zeseramikhi zikwasebenza kancinci malunga ne-30-40% kunentsimbi enobunzima obulinganayo, kwaye zilula kunegranite kakhulu kwiijiyometri ezininzi. Nakweyiphi na inkqubo apho into kufuneka ikhawuleze kwaye ihle ngokuphindaphindiweyo - ingalo yokuphatha i-wafer, inqanaba le-optical eliskena ngokukhawuleza - ukunciphisa ubunzima obuhambayo ngaphandle kokunciphisa ukuqina kuguqulela ngqo kwi-throughput ephezulu kunye nomthwalo ophantsi we-servo motor. Oku kuyinxalenye yesizathu sokuba iindawo zeseramikhi ziye zaxhaphaka kwizixhobo zokukhetha nokubeka ezikhawulezayo nakwiinqanaba zokuhamba zeenkqubo ze-AOI (ukuhlolwa kwe-optical okuzenzakalelayo), apho ixesha lokujikeleza liyindleko ethe ngqo.
Ingxaki: iindleko zomatshini kunye nexesha lokuqhuba
Akukho nanye kwezi zinto ephumayo. I-ceramic echanekileyo inzima kwaye icotha ukuyifaka kumatshini - ubunzima obufanayo obuyenza ingagugi ikwenza kubize kakhulu ukuyigaya ide iqine, kwaye iijometri ezintsonkothileyo zihlala zifuna izixhobo zedayimani kunye namaxesha amade kakhulu okujikeleza kunenxalenye yesinyithi okanye yegranite efanayo. Yingakho i-ceramic idla ngokugcinelwa izinto ezithile ezifuna iipropati zayo - iindawo zokubeka iibheringi, iipleyiti zokuguguleka, izinto zegumbi - endaweni yokusetyenziswa njengezinto ezipheleleyo zebhedi yesakhiwo, apho i-granite okanye i-mineral casting ihlala ibiza kakhulu kumlinganiselo ofanayo wokuqina-kwixabiso.
Uluhlu olukhulayo lwezicelo
Indawo ecacileyo yokukhula kweeseramikhi ezichanekileyo ngoku zizixhobo zokwenza iibhetri kunye nee-semiconductor, apho amagumbi enkqubo ahlala efuna izixhobo ezingaqhubi kakuhle, ezingasebenzisi khemikhali, kwaye ezizinzileyo ngaxeshanye phantsi komjikelo wobushushu ophindaphindwayo - indibaniselwano ethintela uninzi lweentsimbi ngokupheleleyo. Njengoko imigca yokuhlolwa kwebhetri ye-lithium kunye nezixhobo zokupakisha ze-semiconductor ziqhubeka nokunyusa ukunyamezelana okuqinileyo, amaphepha eenkcukacha zezi matshini abiza kakhulu izinto zeseramikhi ngamagama endaweni yokushiya ukhetho lwezinto ezibonakalayo kwinqaku eliqhelekileyo "lezinto eziqinileyo nezizinzileyo", olu luphawu oluhle lokuba ishishini lidlulile ekuphatheni iseramikhi njengokhetho olungaqhelekanga kwaye laqala ukuyiphatha njengesixhobo esiqhelekileyo kwikhithi yenjineli yokuchaneka.
