Iibhloko zakho zentsimbi ziyakukhohlisa.
Hayi ngabom. Kodwa emva kweenyanga ezintandathu zokusetyenziswa komgangatho evenkileni—ukutshiza kwe-coolant, ubushushu butshintshatshintsha phakathi kokutshintsha kwasekuseni nasemva kwemini, ukuwa ngamanye amaxesha kwipleyiti yesinyithi—elo bhloko “li-10mm” lisenokuba yi-10.0003mm. Okanye i-9.9997mm. Kwaye ukuba usebenzisa i-5-micron tolerances, ezo mpazamo zincinci zihlangana zibe ziindawo ezikrazukileyo.
Le yingxaki ethuleyo ekungekho mntu uthetha ngayo xa kusenziwa umatshini ngokuchanekileyo.
Nantsi into eyenzekayo ngeegeyiji zentsimbi kwiindawo zemveliso.
Intsimbi iyabola. Kwanee-grades "ezingenasici" zinokubola kwaye zitshise xa zichatshazelwe zizinto ezipholileyo, ii-oyile zokusika, okanye ukufuma okuphezulu ngokuhamba kwexesha. Nje ukuba ubuso obusebenzayo buvelise ukubola okuncinci, indlela oziphatha ngayo iyatshintsha. Iibhloko azisabikho. Ukuphakama kuyashukuma.
Intsimbi iyaguga. Ngalo lonke ixesha usonga i-gauge block stack, ususa izinto ezincinci ebusweni. Emva kwemijikelo eyaneleyo—kuxhomekeke kwindlela oyisebenzisa ngayo, mhlawumbi amakhulu ambalwa okwakha i-stack—ukuchaneka kobukhulu kuyaphela ngenxa yokunyamezelana. Isatifikethi sakho sokulinganisa seminyaka emibini eyadlulayo sisenokungabonisi oko ukulinganisayo namhlanje.
Intsimbi iqhuba imagnetism. Kwiilebhu zemetrology nakwiindawo zoomatshini be-CNC, ukuphazamiseka kwemagnethi kwizixhobo ezikufutshane kunokuchaphazela indlela esebenza ngayo i-steel gauge. Akunjalo rhoqo, kungekhona kakhulu—kodwa kwizicelo ezichanekileyo, “akukho okuninzi” kunokuba kuninzi kakhulu.
Intsimbi iyakhula ngokweqondo lobushushu. Ewe, intsimbi ine-coefficient yokwandisa ubushushu eyaziwayo, kwaye iilabhoratri ezilungileyo ziyimbangela yoko. Kodwa ukuguquguquka okuncinci rhoqo kobushushu kuyo yonke imihla yemveliso kudala ukungangqinelani okuncinci kodwa okwenyani kokulinganisa.
Izixhobo zokulinganisa zeseramikhi ziyaziphepha zonke ezi ngxaki.
Kwaye ayilomlingo—yikhemistri nefiziksi kuphela ezenza umsebenzi wazo.
Thatha i-zirconia ceramic. Ubunzima be-1200-1450 HV1, xa kuthelekiswa mhlawumbi ne-700-800 HV kwintsimbi eqinileyo. Oko kuthetha ukuba iibhloko zeegeyiji ezenziwe nge-zirconia zifumana amava amalunga ne-1/10 yesantya sokuguguleka. Kwiseli enye yokusila ebhalwe phantsi, ukutshintshela kwiibhloko zeegeyiji ze-ceramic kwandise amaxesha okulinganisa ukusuka kwiinyanga ezimbalwa ukuya kunyaka ngamnye. Ukugqwala okwakuchaphazela ii-stacks zentsimbi kwi-coolant mist kwaphela nje.
Ipropati engeyomagnethi itshintsha umdlalo kwiindlela ezithile zokusebenza. I-Zirconia inokumelana nomphezulu ongaphezulu kwe-10^14 Ω·cm—ikhusela ngombane, ayisebenzisi magnethi ngokupheleleyo. Oko kususa izinto ezinomtsalane wemagnethi ezinokutshintsha iziphumo zovavanyo. Ukuba ulinganisa izinto zebheringi okanye usebenza kufutshane nezixhobo ze-magnetic chucking, oku kubalulekile.
Kwaye indlela esebenza ngayo i-thermal iyasebenza ngendlela emangalisayo. I-coefficient ye-Zirconia yokwandisa i-thermal imalunga ne-1×10^-5/°C. Oko kufana kakhulu nentsimbi, oko kuthetha ukubala kwakho i-thermal recompension akudingi uyilo olutsha olupheleleyo. Kodwa i-ceramic ayiqhubi ubushushu ngendlela efanayo, ngoko ke i-gradients yobushushu ngaphakathi kwesixhobo ngokwayo incinci. Ukufundwa okufumanayo emva kwemizuzwana engama-30 yokunxibelelana kuzinzile, akushukumi njengoko isixhobo sihamba kancinci.
Ngoku, umbuzo wokwenyani: i-zirconia okanye i-alumina?
I-Zirconia iyaphumelela xa iqinile. Inento ebizwa ngokuba yi-"transformation toughening"—xa ixinezelekile, itshintsha kancinci isigaba esimelana nokwanda kweentanda. Oku kuyenza ixoleleke ngakumbi ukuba uwise ibhloko ye-gauge ngengozi. I-Alumina inzima kodwa ibuthathaka ngakumbi; iimpembelelo zinokubangela ukuqhekeka.
Amandla okugoba eZirconia angama-1100 MPa aphantse aphindwe kathathu kunalawo e-alumina. Ukuba izixhobo zakho ziphathwa gadalala, i-zirconia ilungile ngakumbi.
Kodwa i-alumina inendawo yayo. Ixabiso layo liphantsi, isaqinile kakhulu (HV 1200+), kwaye kwiindlela apho ufuna khona ukwandiswa kobushushu obuphantsi—njenge-optical metrology—i-alumina's CTE ephantsi inokuba luncedo. Ezinye iivenkile ze-precision optical zikhetha i-alumina kuba ayitshisi kakhulu xa ithelekiswa nobushushu.
Nangona kunjalo, kwiindlela ezininzi zokusebenzisa umatshini ngokuchanekileyo, i-zirconia yeyona ilungileyo. Inzuzo yokuqina iyinyani, kwaye ixabiso libuya ngobomi benkonzo ende kunye nokulinganiswa okuncinci.
Ibonakala njani le nto xa isenziwa?
Kwimveliso yeebheringi, iiphini ze-ceramic gauge zijonga ububanzi bomdyarho wangaphakathi nowangaphandle imini yonke. Iiphini zentsimbi zikwimeko enjalo? Ukuvezwa kwe-coolant, ungcoliseko lwamasuntswana esinyithi, ukuphathwa rhoqo. Iiphini ze-ceramic azidli, azitsali inkunkuma yesinyithi, kwaye ubunzima obuphezulu buthetha ukuba ubuso bokulinganisa buhlala bunyamezelekile ixesha elide. Omnye umenzi weebheringi uxele ukuba izinga labo lokutshintshwa kweephini zokuhlola lehle malunga nama-80% emva kokutshintshela kwi-ceramic.
Kwiivenkile zokubumba nezixhobo, ii-V-blocks zeseramikhi kunye nemiphetho ethe tye zilinganisa ubunzulu bemiqolo, ubukhulu beebhleyidi, kunye nokulungelelaniswa kwezinto. Umba wokungabikho kokugcinwa ukhulu apha—akukho mafutha, akukho kuhlolwa kokugqwala, akukho xhala malunga nokuba loo pleyiti yomphetho ishiywe ngaphandle ngobusuku obunye. Yilahle, uyicoce, uyisebenzise.
Kwimveliso yezinto ezibonakalayo, izixhobo zokulinganisa zeseramikhi zichukumisa iilensi kunye neeprism ezingenako ukukrwelwa. Uburhabaxa bomphezulu weebhloko zeseramikhi ezisemgangathweni—iRa ≤ 0.2 micrometers—ayiyi konakalisa iglasi yeseramikhi epholisiweyo. Kwaye ngenxa yokuba iseramikhi ayisebenzi ngokweekhemikhali, akukho mngcipheko wokungcola kwe-ion yesinyithi okuchaphazela ukugqunywa kweelensi okanye ukusasazeka kwe-transmissivity.
Kwi-semiconductor nakwi-elektroniki, iipropati ezingezizo eziqhuba umbane, ezingezizo ezitsala umbane zisusa ukuphazamiseka kwiinkqubo zokulinganisa ezisekwe kwi-capacitive kunye ne-induction. Izixhobo zentsimbi ezikufutshane nezinto ezibuthathaka zinokubangela zonke iintlobo zeengxaki ezingabonakaliyo ekunzima ukuzilandela.
Izinto ezimbalwa eziluncedo ekufuneka uzazi.
Ukukhetha amanqaku kusebenza njengeebhloko zentsimbi: Udidi 0, 1, 2, kunye no-3, ngokwemigangatho ye-ISO 3650. Uninzi lwezicelo zoomatshini bokuchwetheza ngokuchanekileyo zifuna Udidi 0 okanye Udidi 1. Ukuba wenza umsebenzi ongadingi loo mgangatho wokuchwetheza, musa ukuwuhlawulela.
Ukugcina izinto kulula kunentsimbi. Akukho oyile, akukho zigqubuthelo ezithintela umhlwa, akukho khabhathi ilawulwa ngumswakama ifunekayo. Gcina izinto zicocekile xa ziza nazo. Azibuthathaka, kodwa ukuzilungisa kunciphisa ubomi bezixhobo.
Ukulinganisa kusafuneka. I-ceramic ayikususi ngokupheleleyo ukutyibilika—icotha kakhulu kunentsimbi. Ukulinganisa ngonyaka kuyinto eqhelekileyo kwizixhobo ezisetyenziswa kwimveliso; ezinye iivenkile zithatha iinyanga ezili-18-24 ukuba ukusetyenziswa kuncinci.
Iprimiyamu yexabiso iyinyani kodwa ifanelekile. Lindela ukuhlawula mhlawumbi i-30-50% ngaphezulu kwangaphambili kunee-equivalents zentsimbi. Kodwa xa ujonga amaxesha okwandiswa kokulinganisa, ukuncipha kokuphindaphinda kokutshintshwa, kunye nokungaphumeleli okunxulumene nokugqwala, iindleko zizonke zobunini kwiminyaka emihlanu zihlala ziphuma zilungile okanye zingcono.
Nantsi intelekelelo ekhawulezileyo ebeka oku kwindawo efanelekileyo.
Iseti yakho yebhloko yegeyiji yentsimbi, ukusetyenziswa kwemveliso, iimeko zomgangatho wevenkile:
- Ukulinganisa rhoqo emva kweenyanga ezi-3-6 ngenxa yokuguguleka nokugqwala
- Ukutshintshwa kweebhloko ezisetyenziswa kakhulu rhoqo emva kweminyaka emi-2-3
- Iimpazamo zokulinganisa ngamanye amaxesha ezivela ekugqwaleni okanye ekuwohlokeni komphezulu
- Ukucoca imihla ngemihla kunye nokuthambisa ngeoyile ukuthintela ukugqwala
Ukusetyenziswa okufanayo, iibhloko ze-ceramic gauge:
- Ukulinganisa rhoqo emva kweenyanga ezili-12-18
- Ukutshintshwa kuphela xa yonakele ngokwasemzimbeni
- Ukuziphatha kokulinganisa okuqhubekekayo nokuqikelelwayo
- Sula, gcina, ugqibile
Loo mahluko kwindlela yokusebenza uyinyani. Kwaye kwivenkile exakekileyo apho i-QC tech yakho sele ilula, ukususa i-variable enye yokulungisa kwi-equation kubaluleke kakhulu.
Ukuba izixhobo zokulinganisa zeseramikhi ziyavakala na kumsebenzi wakho kuxhomekeke kwimeko yakho ethile.
Ukuba usebenzisa amandla okunyamezelana, usebenza kwiindawo ezinzima, okanye uchitha ixesha elininzi ulwa nokulungiswa kweebhloko zegauge, mhlawumbi iswitshi ifanelekile ukuyihlola. Qala ngeseti enye—ikhithi yebhloko yegauge esisiseko kuluhlu lwakho oluqhelekileyo—kwaye ubone ukuba isebenza njani xa ithelekiswa nomsebenzi wakho wangoku.
Uninzi lweevenkile ezizama i-ceramic azibuyeli kwintsimbi.
