Amabhulokhi akho ensimbi aqamba amanga kuwe.
Hhayi ngamabomu. Kodwa ngemva kwezinyanga eziyisithupha zokusebenzisa phansi esitolo—ukuchaphaza okupholile, ukushintsha kwezinga lokushisa phakathi kokushintsha kwasekuseni nantambama, ukuwa ngezikhathi ezithile epuletini lensimbi ecijile—lelo bhulokhi “eliyi-10mm” lingase libe yi-10.0003mm. Noma i-9.9997mm. Futhi uma usebenzisa ukubekezelelana kwama-micron ama-5, lawo maphutha amancane ahlangana abe izingxenye ezilahliwe.
Lena inkinga ethule okungekho muntu okhuluma ngayo ekusetshenzisweni kwemishini ngokunemba.
Nakhu okwenzekayo ngempela ngamageyiji ensimbi ezindaweni zokukhiqiza.
Insimbi iyagqwala. Ngisho nezinhlobo "ezingenasici" zingagqwala futhi zishiye amabala lapho zivezwa kuma-coolant, uwoyela wokusika, noma umswakama ophezulu ngokuhamba kwesikhathi. Uma ubuso obusebenzayo buqala ukugqwala okuncane kakhulu, ukuziphatha kwakho kokugoba kuyashintsha. Amabhulokhi awasaqini. Ukuphakama kuyakhukhuleka.
Insimbi iyaguga. Njalo uma usonga inqwaba yamabhulokhi egeji ndawonye, ususa inani elincane lezinto ebusweni. Ngemva kwemijikelezo eyanele—kuye ngokuthi uyisebenzisa kanjani, mhlawumbe ukwakheka kwenqwaba engamakhulu ambalwa—ukunemba kobukhulu kuyaphuma ekubekezeleleni. Isitifiketi sakho sokulinganisa seminyaka emibili edlule kungenzeka singabonisi lokho okukalayo namuhla.
Insimbi iqhuba amandla kazibuthe. Emalabhorethri e-metrology kanye nasezikhungweni zomshini we-CNC, ukuphazamiseka kwamandla kazibuthe okuvela emishinini eseduze kungathinta ngempela ukuziphatha kwe-steel gauge. Hhayi njalo, hhayi ngendlela emangalisayo—kodwa ezisetshenzisweni ezinembe kakhulu, “hhayi okuningi” kungaba yinto eningi kakhulu.
Insimbi iyakhula ngokushisa. Yebo, insimbi ine-coefficient yokwanda kokushisa eyaziwayo, futhi amalabhorethri amahle ayimbangela yalokho. Kodwa ukushintshashintsha kwezinga lokushisa okuncane njalo phakathi nosuku lokukhiqiza kudala ukungalingani okuncane kodwa kwangempela kokulinganisa.
Amathuluzi okulinganisa e-ceramic agwema zonke lezi zinkinga.
Futhi akuwona umlingo—kuwukhemistri kanye nefiziksi kuphela ezenza umsebenzi wazo.
Thatha i-zirconia ceramic. Ukuqina okungu-1200-1450 HV1, uma kuqhathaniswa mhlawumbe no-700-800 HV wensimbi eqinile. Lokho kusho ukuthi amabhlogo e-gauge enziwe nge-zirconia athola cishe ingxenye yeshumi yesilinganiso sokuguguleka. Kwiseli elilodwa lokugaya ngokunemba elibhalwe phansi, ukushintshela kumabhlogo e-gauge e-ceramic kwandise izikhawu zokulinganisa kusukela njalo ezinyangeni ezimbalwa kuya onyakeni ngamunye. Ukugqwala okwakuhlupha izinqwaba zensimbi zabo enkungwini yokupholisa kwanyamalala nje.
Isici esingeyona i-magnetic sishintsha kakhulu izinhlelo zokusebenza ezithile. I-Zirconia inokumelana nobuso okungaphezu kuka-10^14 Ω·cm—ivikela ngogesi, ayiyona i-magnetic ngokuphelele. Lokho kususa izinto ezikhangayo ezingenza imiphumela yokuhlola ishintshe. Uma ulinganisa izingxenye zebhere noma usebenza eduze kwemishini ye-magnetic chucking, lokhu kubalulekile.
Futhi ukuziphatha kokushisa kuyasebenza ngendlela emangalisayo. I-coefficient ye-Zirconia yokwandisa ukushisa ingama-1 × 10 ^ -5 / °C. Lokho kucishe kufane nensimbi, okusho ukuthi izibalo zakho zokunciphisa ukushisa azidingi ukwakhiwa kabusha okuphelele. Kodwa i-ceramic ayiqhubeki nokushisa ngendlela efanayo, ngakho-ke ama-gradients okushisa ngaphakathi kwethuluzi ngokwalo mancane. Ukufundwa okutholayo ngemva kwemizuzwana engama-30 yokuthintana kuzinzile, akusheleli njengoba ithuluzi lilingana kancane.
Manje, umbuzo wangempela: i-zirconia noma i-alumina?
I-Zirconia iyanqoba ngokuqina. Inalokho okubizwa ngokuthi “ukuqina kokuguqulwa”—uma icindezelekile, idlula ekushintsheni kwesigaba okuncane okumelana nokusabalala kwemifantu. Lokhu kuyenza ithetheleleke kakhulu uma uphonsa i-gauge block ngengozi. I-Alumina ilukhuni kodwa iyaphuka kalula; imiphumela ingabangela ukuqhekeka.
Amandla okugoba e-Zirconia angaba ngu-1100 MPa cishe aphindwe kathathu kune-alumina. Uma amathuluzi akho ephathwa kabi, i-zirconia ibekezelela kakhudlwana.
Kodwa i-alumina inendawo yayo. Ishibhile, isaqinile kakhulu (HV 1200+), futhi uma udinga ukunwetshwa kokushisa okuncane kakhulu—njenge-optical metrology—i-CTE ephansi ye-alumina ingaba yinzuzo. Ezinye izitolo ze-optical ezinembile zikhetha i-alumina ngoba ayisheleli kakhulu uma kuqhathaniswa nokushisa.
Nokho, ngezinhlelo zokusebenza eziningi zokulungisa ngokunemba, i-zirconia iyinto enhle kakhulu. Inzuzo yokuqina ingokoqobo, futhi iprimiyamu yezindleko ibuya ngokuphila isikhathi eside kwenkonzo kanye nokulinganiswa okuncane.
Lokhu kubonakala kanjani empeleni?
Ekukhiqizeni amabhereyi, amaphini e-ceramic gauge ahlola ububanzi bomjaho wangaphakathi nowangaphandle usuku lonke. Amaphini ensimbi akuleyo ndawo? Ukuvezwa kwe-coolant, ukungcola kwezinhlayiya zensimbi, ukuphathwa njalo. Amaphini e-ceramic awagqwali, awadonsi imfucumfucu yensimbi, futhi ubulukhuni obuphezulu busho ukuthi ubuso bokulinganisa buhlala bubekezelelana isikhathi eside kakhulu. Omunye umenzi wamabhereyi ubike ukuthi izinga lokufaka esikhundleni amaphini abo okuhlola lehle cishe ngo-80% ngemva kokushintshela ku-ceramic.
Ezitolo zesikhunta nezama-tooling, ama-V-blocks e-ceramic kanye nemiphetho eqondile alinganisa ukujula kwe-cavity, ubukhulu be-blade, kanye nokulungiswa kwe-fixture. Isici sokungabi nokulungiswa okukhulu lapha—akukho ukugcotshwa kwamafutha, akukho ukuhlolwa kokugqwala, akukho ukukhathazeka ngokuthi ngabe lelo plate lomphetho lishiywe ngaphandle ubusuku bonke. Lilahle, lihlanze, ulisebenzise.
Ekukhiqizweni kwezingxenye ze-optical, amathuluzi okulinganisa i-ceramic athinta amalensi nama-prism angenakuklwejwa. Ubulukhuni bomphezulu wamabhulokhi e-ceramic gauge asezingeni eliphezulu—ama-Ra ≤ 0.2 micrometer—ngeke kulimaze ingilazi ye-optical epholishiwe. Futhi ngenxa yokuthi i-ceramic ayisebenzi ngamakhemikhali, akukho bungozi bokungcoliswa kwe-ion yensimbi okuthinta ukumbozwa kwelensi noma ukudluliselwa kwe-transmissivity.
Kuma-semiconductor kanye nama-electronics, izakhiwo ezingezona eziqhuba ugesi, ezingezona ezikagesi ziqeda ukuphazamiseka kwezinhlelo zokulinganisa ezisekelwe ku-capacitive kanye ne-induction. Amathuluzi ensimbi aseduze kwezingxenye ezibucayi angabangela zonke izinhlobo zezinkinga ezicashile okunzima ukuzilandela.
Izinto ezimbalwa eziwusizo okufanele uzazi.
Ukukhetha ibanga kusebenza njengamabhulokhi e-gauge ensimbi: Ibanga 0, 1, 2, kanye ne-3, ngokwezindinganiso ze-ISO 3650. Izinhlelo eziningi zokusebenza zokulungisa ngokunemba zidinga iBanga 0 noma iBanga 1. Uma wenza umsebenzi ongadingi lelo zinga lokunemba, ungawukhokheli.
Indawo yokugcina izinto ilula kunensimbi. Akukho mafutha, akukho zimbozo ezivimbela ukugqwala, akukho ikhabethe elilawulwa umswakama elidingekayo. Gcina izinto zihlanzekile kuphela uma zifika nazo. Azibuthakathaka, kodwa ukuziphatha kunciphisa impilo yanoma yiliphi ithuluzi.
Ukulinganisa kusadingeka. I-Ceramic ayikuqedi ngokuphelele ukukhukhuleka—ihamba kancane kakhulu kunensimbi. Ukulinganisa kwaminyaka yonke kuyindinganiso yamathuluzi okusetshenziswa ekukhiqizeni; ezinye izitolo zidlulela ezinyangeni ezingu-18-24 uma ukusetshenziswa kulula.
Iprimiyamu yezindleko ingokoqobo kodwa inengqondo. Lindela ukukhokha mhlawumbe ngo-30-50% ngaphezulu kusengaphambili kunezinsimbi ezilingana nensimbi. Kodwa uma ubheka izikhawu zokulinganisa ezinde, imvamisa yokushintsha encishisiwe, kanye nokwehluleka okuhlobene nokugqwala, izindleko eziphelele zobunikazi eminyakeni emihlanu zivame ukuphuma zilingana noma zingcono.
Nasi isiqhathaniso esisheshayo esibeka lokhu endaweni efanele.
Isethi yakho yebhulokhi yegeyiji yensimbi, ukusetshenziswa komkhiqizo, izimo zephansi lesitolo:
- Ukulinganisa njalo ezinyangeni ezi-3-6 ngenxa yokuguguleka nokugqwala
- Ukushintsha amabhlogo asetshenziswa kakhulu njalo eminyakeni emi-2-3
- Amaphutha okulinganisa ngezikhathi ezithile avela ekugqwaleni noma ekuwohlokeni kwendawo
- Ukuhlanza nokugcoba ngamafutha nsuku zonke ukuze kuvinjelwe ukugqwala
Ukusetshenziswa okufanayo, amabhlogo e-ceramic gauge:
- Ukulinganisa njalo ezinyangeni ezingu-12-18
- Ukufakwa esikhundleni kuphela uma konakele ngokomzimba
- Ukuziphatha kokulinganisa okuvumelanayo nokubikezelwayo
- Sula, gcina, kuqediwe
Lowo mehluko endleleni yokusebenza ungokoqobo. Futhi esitolo esimatasa lapho ubuchwepheshe bakho be-QC buvele bunwetshiwe, ukususa i-variable eyodwa yokulungisa kulesi sibalo kubaluleke kakhulu.
Ukuthi amathuluzi okulinganisa e-ceramic anengqondo yini ekusebenzeni kwakho kuncike esimweni sakho esithile.
Uma usebenzisa ukubekezelelana okuqinile, usebenza ezindaweni ezinzima, noma uchitha isikhathi esiningi ulwa nokulungiswa kwe-gauge block, i-switch cishe ifanele ukuyihlola. Qala ngesethi eyodwa—ikhithi ye-gauge block eyisisekelo ebangeni lakho elivamile—bese ubona ukuthi isebenza kanjani uma kuqhathaniswa nomsebenzi wakho wamanje.
Izitolo eziningi ezizama i-ceramic azibuyeli emuva ensimbini.
