Indlela Yokukhetha Ibhulokhi Elifanele Lokulinganisa Ukulinganisa Okuphezulu

Amabhulokhi egeyiji (avame ukubizwa ngokuthi amabhulokhi e-Jo) asebenza njengendinganiso eyinhloko yomzimba ye-dimensional metrology emhlabeni wonke. Ukulinganiswa ngakunye kwe-micrometer, i-height gauge zeroing, kanyeumshini wokulinganisa ohlanganisayoUkuhlolwa kwe-axis (CMM) kulandelela uhlu lwayo lobukhulu emuva kuqoqo olugoqekayo lwamabhulokhi e-gauge aqinisekiswe ngokumelene nama-interferometer e-laser.

Ukukhetha izinto ezingalungile noma ibanga lokunemba kuletha amaphutha amancane okushisa, ukwehluleka kokusonta, kanye nokuguguleka okungadingekile. Isethi yokulinganisa yeBanga K eyenzelwe ilebhu yokulawula imvelo izowohloka ngokushesha uma ifakwa phansi esitolo esinamafutha, kuyilapho isethi yensimbi engabizi esetshenziselwa ukusethwa kwe-comparator enokunemba okuphezulu iletha ukungaqiniseki okungamukeleki.

Ukuqonda amamaki okunemba, i-physics yezinto ezibonakalayo, kanye ne-wringing dynamics kuqinisekisa ukuthi ukusethwa kwekhwalithi yakho kugcina uchungechunge olungapheli lokulandelela kwe-metrological.

1. Ukukhetha Ibanga Lokunemba Elifanele (ISO 3650 / ASME B89.1.9)

Izindinganiso zomhlaba wonke zihlukanisa amabhlogo e-gauge abe amamaki amane ayisisekelo ngokusekelwe ekuphambukeni kobude kanye nokubekezelelana kokuthamba:

+-------------------+- ...

Ibanga K (Ibanga Lokulinganisa)

Amabhulokhi eBanga K athwala ubude obuqinile kanye nokubekezelelana okufana, kodwa awasetshenziswa ekulinganisweni kwansuku zonke okuvamile. Umsebenzi wawo kuphela ukulinganisa amabhulokhi okulinganisa okusebenza (iBanga 0 noma 1). Amalabhorethri asebenzisa amasethi eBanga K adinga ama-interferometer ebanga eliphezulu noma ama-comparator omshini ukuze abambe ukuhlukahluka kwama-intshi amancane.

Ibanga 0 kanye nebanga 1

Ibanga 0 lisebenza njengendinganiso yokusebenza ngaphakathi kwamakamelo okuhlola alawulwa yisimo sezulu ukuze kulinganiswe ama-micrometer, amasongo okusetha, kanye nama-probe kagesi. Amabhulokhi ebanga 1 aphatha ukuhlolwa okunembile okuvamile phansi kwesitolo lapho ukuguquguquka kwezinga lokushisa kuhlala ngaphakathi kwemingcele ephakathi.

2. Ukukhethwa Kwezinto: Insimbi vs. I-Carbide vs. I-Ceramic

Ukukhetha izinto ezifanele kudinga ukulinganisela ukuhambisana nokukhula kokushisa, ukumelana nokuguguleka, kanye nokuzivikela kokugqwala.

+------------------------------+-----------------------------------+-----------------------------------+ | Impahla Yezinto Eziphathekayo | Insimbi (I-alloy) | I-Tungsten Carbide | I-Ceramic (i-Zirconia) | +- ... +- ...+

Insimbi

Insimbi isalokhu iyisinqumo sendabuko nesingambi eqolo. I-coefficient yayo yokwandisa ukushisa ifana kakhulu nezingxenye zemishini yensimbi evamile, inciphisa amaphutha okukhulisa umehluko ngesikhathi sokuhlolwa kwesitolo. Kodwa-ke, insimbi idinga ukugcotshwa ngowoyela njalo ukuze kuvinjelwe ukugqwala nokuklwebheka kalula lapho ivezwa enhlabathini.

I-Tungsten Carbide

I-Carbide inikeza ukumelana nokuguguleka okuphindwe kayishumi kunensimbi yamathuluzi. Ukuqina kwayo okuphezulu kanye nokumelana nokuklwebheka kwenza kube kuhle kakhulu eziteshini zokuhlola ezinomthamo ophezulu. Kodwa-ke, i-coefficient yayo yokwandisa ukushisa okuphansi (~ 4.5 × 10⁻⁶/C) idinga izici zokulungisa ukushisa ngokucophelela lapho ilinganisa izingxenye zensimbi emazingeni okushisa akude no-20℃.

I-Zirconia Ceramic

I-Zirconia ceramic isibe yinto ethandwayo kuma-laboratory asezingeni eliphezulu anamuhla. Amabhlogo e-ceramic awagqwali ngokuphelele, awasebenzi ku-magnetic, futhi awangenwa yi-micro-burrs. Ukuwisa ibhlogo le-ceramic ngeke kuphakamise i-edge burr; imane iqhekeze kahle ngaphandle kokuphazamisa izindiza ezizungezile ezisicaba. Ngaphezu kwalokho, izinga layo lokukhula kokushisa (~ 9.8 × 10⁻⁶/C) lihambisana kakhulu nensimbi, okwenza kube lula ukubala isinxephezelo sokushisa.

3. Isenzakalo Esisontekile kanye Nekhwalithi Yomphezulu

Ukusonta—inqubo yokushelela amabhlogo amabili ahlanzekile, ayisicaba ndawonye ngaphansi kwengcindezi encane ukuze anamathele ngaphandle kwezibambo zangaphandle—kuncike ekuthinteni kwama-molecule ayisicaba kakhulu kanye nokukhangwa kwama-molecule kumafilimu amancane aketshezi.

INDLELA YOKUQHUMA Ibhulokhi A (Phezulu) [===============================]=" ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ <-- Ifilimu kawoyela elincanyana kakhulu (isikali se-nanometer) Ibhulokhi B (Ngezansi) [=================================]=" --> Ukukhanga kwama-molecule + ingcindezi yomoya kuhlanganisa amabhulokhi ndawonye ngokuqinile.

Ukusonta okuphumelelayo kudinga i-topography ehlanzekile ebusweni. Uma isisekelo se-gauge block noma ubuso bokulinganisa bunama-scratch burrs, uthuli oluphuma emoyeni, noma ukwakheka kwefilimu kawoyela, igebe lokusonta liyakhula ngama-nanometer angamakhulu amaningana, okwenza ukulinganisa kwe-Grade 0 kungavumelekile.

Esikhungweni sethu sokukhiqiza saseJinan, ukugcina ukunemba kokulinganisa kwezindinganiso zokulinganisa zangaphakathi kuncike ekuhlanganiseni amabhlogo e-ceramic kanye ne-gauge yensimbi namapuleti obuso be-granite amnyama e-ZHHIMG® (≈ 3100 kg/m³). Ngenxa yokuthi i-granite enobuningi obuphezulu inikeza isisekelo esingasebenzi, esingenamagnetic, esinama-micro-lapped ngaphakathi kwama-workshop ethu okushisa okungaguquki angu-10,000 m², ochwepheshe bangagoqa futhi baqinisekise amabhlogo ngaphandle kokuphazamiseka kokudlidliza komhlaba okushintsha ukufundwa kobude.

4. Ukulandelela Ukulinganisa kanye Nokulawulwa Kwemvelo

Ukuthenga amabhlogo asezingeni eliphezulu akusho lutho uma indawo yakho yokulinganisa ingenakho ukuzinza kwemvelo kanye nokulandelela kwe-metrological.

1. Ukucwilisa Izinga Lokushisa: Ngaphambi kokulinganisa noma ukusonta, vumela amabhlogo nezinto zokusebenza ukuthi zicwilise elabhorethri elilawulwa yisimo sezulu (20 ℃) ​​okungenani amahora ama-2 kuya kwangama-4. Ukuphatha amabhlogo ngqo ngezandla ezingenalutho kudlulisa ukushisa komzimba ngokushesha, kwandise ibhlogo elingu-100 mm nge-micron egcwele ngemizuzwana. Sebenzisa njalo izinti ezivalekile noma amagilavu ​​​​ekotini.

2. Ukulandelela Kwelabhorethri Kazwelonke: Qinisekisa ukuthi izitifiketi zokulinganisa zivela ezindaweni ezigunyaziwe ezilandelelwa emuva ezikhungweni zikazwelonke zokulinganisa (i-NIM, i-PTB, i-NPL, noma i-NIST). Zonke izindinganiso zedivayisi ezisetshenziswa e-ZHHIMG zinokuqinisekiswa kokulinganisa okukhishwe yizikhungo ezigunyaziwe zokulinganisa zesifundazwe nezesizwe.

3. Izindlela Zokuhlanza: Hlanza amabhlogo ngaphambi nangemva kokusebenzisa usebenzisa ama-wipes angenamanzi acwebezelayo kanye nama-wipes angena-lint. Amasethi ensimbi kumele ambozwe kancane nge-petrolatum engena-acid ngaphambi kokugcinwa.

Uhlu Lokuhlola Lokusebenza Lonjiniyela Bekhwalithi

Uma ukhetha amabhlogo okulinganisa esikhungo sakho:

• Qondanisa izinto ezihlanganisiwe nezinto zakho zokusebenza: Khetha i-ceramic yokuhlola insimbi ejwayelekile kanye nokusetshenziswa kwegumbi lokuhlanza; khetha i-carbide yezindawo zokusebenzela ezigqokwa kakhulu.

• Gcina amabhlogo eBanga K kanye neBanga 0 ngokuqinile ngaphakathi kwamakamelo okulinganisa alawulwa yisimo sezulu (20°C ± 0.5°C).

• Ungalokothi ugcine amabhlogo ahlanganiswe ndawonye ubusuku bonke. Ukushisela okubandayo kanye nomswakama womoya kuzohlukanisa ubuso obuthintanayo unomphela.

• Qinisekisa ukuthi ipuleti lakho elingaphezulu eliyisithenjwa lisicaba (DIN 876 Grade 00) ngaphambi kokusetha izitendi zokuqhathanisa ukuze ugweme amaphutha okuphambuka kwesisekelo.

Ngokufanisa ibanga, izinto zokwakha, kanye nenqubo yokuphatha nendawo yakho yokulinganisa ethile, ilebhu yakho igcina isisekelo sokubhekisela esiqinile sayo yonke imikhiqizo ephuma efektri yakho.
