Indlela Yokuqinisekisa Ukuthamba Kwepuleti Lomphezulu Wegranite

U-ode ipuleti lobuso le-granite lebanga le-00. Umhlinzeki uthi liqinisekisiwe. Ibhokisi liyafika. Usayina irisidi lokulethwa.

Ngemva kwezinyanga eziyisithupha, umhloli wakho wekhwalithi wenza ukuhlolwa okuvamile kwe-autocollimator futhi uqaphela ukuthi ipuleti seliphumile ngaphandle kokubekezelelana. Uvula isimangalo. Umhlinzeki ukhomba isiginesha esiserisidini lakho lokulethwa.

Lesi simo senzeka kaningi kunalokho okufanele. Hhayi ngoba abathengi abanaki — kodwa ngoba iningi labathengi abazi ukuthi yini okufanele bayihlole ngaphambi kokuba lelo peni lifike ephepheni.

Lo mhlahlandlela ukunika izindlela zangempela. Akukho lutho oluyinkimbinkimbi. Ungakuthatha lokhu uye endaweni yakho yokuhlola kusasa.

TL;DR

Amabanga okusicaba (Ibanga 00: ≤0.5μm/m, Ibanga 0: ≤1μm/m, Ibanga 1: ≤2μm/m) amelela inani langempela lokulinganisa, hhayi amalebula okumaketha. Ngaphambi kokusayina noma yiliphi irisidi lokulethwa: sebenzisa isivivinyo somucu wephepha njengesango lokuqala lokudlula (imizuzu emi-5-10), bese wenza isilinganiso segridi ye-autocollimator esifanele (imizuzu engama-45-90). Ipuleti ngalinye le-ZHHIMG® lithunyelwa nokuqinisekiswa kwe-German Mahr 0.5μm, ukuqinisekiswa kwezinga le-elekthronikhi laseSwitzerland WYLER, kanye nokuhlolwa kwe-cross-check ye-Renishaw laser interferometer — konke kulandelelwa ezikhungweni ze-metrology zikazwelonke. Uma ukuhlolwa kwakho okungenayo kuthola inkinga, yibhale phansi ngokushesha ngedatha yakho yokulinganisa ngaphambi kokusayina.

Kungani Abathengi Baphesheya Abangama-70% Bengayihloli Ipuleti Labo Lomphezulu Wegranite Lapho Befika

Ake ngikutshele ukuthi kwenzekani ngempela lapho umuntu ethola usizo.

Iningi labathengi baphesheya liyasithemba isitifiketi sokulinganisa somhlinzeki. Bacabanga ukuthi ilebhu yangaphandle noma isitifiketi sangaphakathi somkhiqizi sihle ngokwanele. Bayasayina, baqhubeke.

Inkinga: leso sitifiketi sakhiqizwa ezinsukwini noma amasonto ngaphambi kokuba ipuleti lifike phansi kwakho. Ngesikhathi sokuthutha — ikakhulukazi ukuthunyelwa kwezitsha emizileni yolwandle — amapuleti ongaphezulu kwe-granite angaba nokushaqeka kokushisa, ukucindezeleka kokudlidliza, kanye nokuthinteka ngokomzimba. Ipuleti elishiye ifektri lingakwazi ukubekezelela lingafika endaweni yakho ngaphandle kwesidingo.

Ngibone abathengi bethola lokhu lapho ekugcineni besebenzisa ukuhlolwa kwabo kwe-autocollimator ngesikhathi sokuhlolwa kwesikhungo. Ngaleso sikhathi, iwindi lokuthumela selivaliwe, iwindi lokufaka isimangalo seliphelelwe yisikhathi, futhi baphethe ipuleti lika-$15,000 leBanga 00 abangakwazi ukulisebenzisa emsebenzini weBanga 00.

Isixazululo akusona i-paranoia. Kuyinqubo yokuhlola yemizuzu engama-20 ongayisebenzisa ngemishini eyisisekelo.

Ukuqonda iBanga 00, iBanga 0, kanye neBanga 1: Lokho Okushiwo Yilawo Manombolo Ngempela Kuma-Micron

Ngaphambi kokuthi uqinisekise ukuthi i-flat iqondile, udinga ukwazi ukuthi ufunani.

Amabanga okusicaba achazwa ezindinganisweni eziningana zamazwe ngamazwe — DIN876, ASME B89, JIS, GB/T — futhi wonke ahlangana ngencazelo efanayo eyisisekelo. Nakhu okushiwo amabanga empeleni:

Ake ngihumushe lokhu kube izinombolo zangempela.

Kupuleti elijwayelekile elingu-1000 × 630 mm (usayizi ovame kakhulu wokuthumela ngaphandle), iBanga 00 livumela ukuphambuka okuphelele kokusicaba okungaba ngu-1.5 μm kulo lonke ubuso. Lokho cishe kungama-1/50th ububanzi beseli elibomvu legazi lomuntu. IBanga 0 liphinda kabili lokho kube cishe ama-3 μm. IBanga 1 lihlala cishe kuma-6 μm.

Nakhu-ke abathengi abaningi abakuphuthelwa: incazelo imayelana nemitha ngayinye yobude bomphezulu, hhayi ukuphambuka kwepuleti eliphelele.

Uma uthenga ipuleti elingu-2000 × 1000 mm, ukubekezelelana kwebanga kusebenza ngokwehlukana kuyo yonke imitha eqondile ebusweni. Ukuphambuka kwakho okuphezulu okuvunyelwe kubalwa ngokusekelwe kubukhulu obude. Ngepuleti elingu-2000 mm, ubheka cishe u-2.5 μm weBanga 00, u-5 μm weBanga 0, kanye no-10 μm weBanga 1.

Lezi izinombolo ongazilinganisa ngempela. Uma othile ekutshela ukuthi ipuleti lakhe le-Grade 00 elingu-2000 mm “linezinhlobo ezingaba ngu-3 zama-micron” — lokho kungaphakathi kwencazelo. Uma bethi “cishe ama-micron angu-8” — lokho kuyindawo ye-Grade 1, hhayi i-Grade 00.

Cacisa izinombolo ngaphambi kokusayina noma yini.

Ukuhlolwa Kwephepha: Indlela Esheshayo Yomsebenzi Wonke Ochwepheshe Okufanele Ayazi

Ukuhlolwa komcu wephepha akuyona intoukulinganisa ngokunembaKodwa kuyindlela esheshayo yokubamba izinkinga ezisobala ngaphambi kokuba uchithe isikhathi usetha i-autocollimator.

Nansi indlela esebenza ngayo.

Uzodinga: iphepha lokuphrinta elijwayelekile (70-80 gsm lisebenza kahle), indawo ehlanzekile yepuleti, kanye nezandla eziqinile.

1. Hlanza kahle indawo yepuleti nge-isopropyl alcohol. Noma yimuphi udoti uzodala ukuxhumana okungamanga.

2. Sika imichilo yephepha cishe ibe ngu-20 mm ububanzi kanye no-50-80 mm ubude.

3. Beka imichilo ezindaweni eziqondile ngaphesheya kobuso bepuleti — emakhoneni, maphakathi, kanye nakuma-diagonal.

4. Zama ukushelela igeyiji yokuzwa engu-0.5 mm ngaphansi komcu wephepha ngaphansi kwesisindo sayo.

Lokho okuvivinyayo ngempela: Uma umcu wephepha ushelela ngaphansi kwesisindo sawo, kukhona ukuvuleka — okusho ukuthi ubuso bepuleti buphansi ngaleso sikhathi uma kuqhathaniswa nendawo ezungezile. Lokhu kubonisa ukugoba noma ukucwila kwendawo.

Umkhawulo: Lokhu kuhlolwa akukwazi ukulinganisa ukuphambuka kokuba yisicaba. Kukutshela kuphela ukuthi ubuso bepuleti buthintana nephepha ububanzi balo bonke. Ipuleti lingadlula kulesi sivivinyo kodwa libe ngaphandle kokubekezelelana kwebanga 0.

Ukuhlolwa kwephepha elinomucu kuwusizo njengesango lokuqala lokudlula. Uma kwehluleka, unesizathu esisheshayo sokwenqaba noma sokubamba ukulethwa. Uma kuphumelela, thuthela ku-autocollimator ukuze uqinisekise ngempela.

Indlela Yokuqongelela I-Autocollimator: Indlela Ochwepheshe Abalinganisa Ngayo Ukuthamba Kwe-Sub-Micron

Yilapho ukuqinisekiswa kuba yinto engathi sína khona.

I-autocollimator ilinganisa ukuphambuka kwe-angular kwendawo ekhanyayo ngokubonisa umsebe wokukhanya ohlanganisiwe bese ilinganisa i-engeli ekhanyayo. Ingaxazululeka ifike ku-0.1 arc-second — okuhunyushwa cishe ku-0.5 μm/m endaweni ye-granite.

Imishini oyodingayo:

• · I-optical autocollimator (i-Taylor-Hobson, i-Mahr, noma i-Dietzgen yimikhiqizo evamile yobungcweti)
• · Isibuko esibonakalayo noma okunamathiselwe kwesibuko
• · Isitendi sokufaka esizinzile
• · Ukulawulwa kwemvelo (okunye ngalokhu ngezansi)

Iphrothokholi yokulinganisa:

1. Vumela ipuleti ukuthi lizinze ekushiseni kwegumbi okungenani amahora ama-4 ngemva kokulethwa. I-Granite isabela ekushintsheni kokushisa cishe ku-0.001 mm/°C. Uma ipuleti lifike libanda futhi isitolo sakho sifudumele, linda.

2. Hlanza indawo yonke ngokuphelele.

3. Setha i-autocollimator ku-tripod ezinzile ekugcineni kwepuleti.

4. Chaza igridi yakho yokulinganisa. Ngepuleti elingu-1000 × 630 mm, igridi engu-5 × 5 (amaphuzu okulinganisa angu-25) iyinto ejwayelekile. Amapuleti amakhulu asebenzisa igridi elinganayo.

5. Thatha ukufundwa endaweni ngayinye yokuhlangana kwegridi, uhambisa isibonisi phakathi kwamaphuzu.

6. Qopha konke ukufundwa. Bala inani eliphelele lokufundwa okubonisiwe (TIR) ​​kuwo wonke amaphuzu.

Ngepuleti le-Grade 00 elingu-1000 × 630 mm, i-TIR yakho iyonke akufanele idlule cishe u-1.5 μm.

Amaphutha avamile awenziwa ngabathengi:

• · Ukulinganisa ngokushesha ngemva kokufika kwepuleti (ukushisa)
• · Ukusebenzisa i-autocollimator yedijithali eshibhile ngaphandle kokulinganiswa okuqinisekisiwe
• · Ukuthatha ukufundwa okungu-3-4 kuphela esikhundleni segridi efanele
