Indlela yokuqinisekisa ukuba iGranite Surface Plate Flatness

U-odole ipleyiti yomphezulu wegranite yebanga le-00. Umthengisi uthi iqinisekisiwe. Ibhokisi iyafika. Usayina irisithi yokuhanjiswa.

Emva kweenyanga ezintandathu, umhloli wakho womgangatho wenza uvavanyo oluzenzekelayo aze aqaphele ukuba ipleyiti ayisekho kwimeko yokunganyamezelani. Uvula ibango. Umthengisi ukhomba utyikityo olukwirisithi yakho yokuhanjiswa.

Le meko yenzeka rhoqo kunokuba kufanele. Ayikuko ukuba abathengi abakhathali — kodwa kungenxa yokuba uninzi lwabathengi abazi ukuba mabajonge ntoni ngaphambi kokuba loo peni ifike ephepheni.

Esi sikhokelo sikunika iindlela zokwenyani. Akukho ngxaki. Ungayithatha le nto uye nayo kwindawo yakho yokujonga ngomso.

TL;DR

Amanqanaba okuthamba (Ibanga 00: ≤0.5μm/m, Ibanga 0: ≤1μm/m, Ibanga 1: ≤2μm/m) amele ubungakanani bokulinganisa bokwenyani, hayi iileyibhile zokuthengisa. Ngaphambi kokusayina nayiphi na irisithi yokuhanjiswa: sebenzisa uvavanyo lwephepha njengesango lokuqala lokupasa (imizuzu emi-5-10), emva koko wenze umlinganiselo wegridi ye-autocollimator efanelekileyo (imizuzu engama-45-90). Ipleyiti nganye yomphezulu ye-ZHHIMG® ithunyelwa ngoqinisekiso lwe-German Mahr 0.5μm, uqinisekiso lwenqanaba le-elektroniki laseSwitzerland WYLER, kunye nokuhlolwa kwe-interferometer ye-Renishaw laser - konke oku kulandelelwa kwi-national metrology institutions. Ukuba uhlolo lwakho olungenayo lufumana ingxaki, yibhale ngoko nangoko ngedatha yakho yokulinganisa ngaphambi kokuba usayine.

Kutheni ama-70% abathengi baphesheya bengayihloli ipleyiti yabo yeGranite xa befika

Makhe ndikuxelele ukuba kwenzeka ntoni ngokwenene kwicala elifumanayo.

Uninzi lwabathengi bamanye amazwe bayasithemba isatifiketi sokulinganisa somthengisi. Bacinga ukuba ilebhu yomntu wesithathu okanye isiqinisekiso sangaphakathi somenzi silungile ngokwaneleyo. Bayasayina, baqhubeke.

Ingxaki: eso satifikethi senziwe kwiintsuku okanye iiveki ngaphambi kokuba ipleyiti ifike kumgangatho wakho. Ngexesha lokuhamba - ingakumbi ukuthunyelwa kweekhonteyina kwiindlela zolwandle - iipleyiti zomphezulu wegranite zinokufumana ukutshayiswa kobushushu, uxinzelelo lokungcangcazela, kunye nempembelelo yomzimba. Ipleyiti eshiye umzi-mveliso ingafikeleleka ngokulula kwisakhiwo sakho.

Ndibabonile abathengi befumanisa oku xa ekugqibeleni beqhuba itshekhi yabo ye-autocollimator ngexesha lokuhlolwa kwesakhiwo. Ngelo xesha, isithuba sokuthumela sivaliwe, isithuba sokufaka ibango siphelelwe lixesha, kwaye baphethe ipleyiti ye-$15,000 yeBanga 00 abangenakuyisebenzisa kumsebenzi weBanga 00.

Isisombululo asikokuxakeka. Yinkqubo yokuhlola yemizuzu engama-20 onokuyiqhuba usebenzisa izixhobo ezisisiseko.

Ukuqonda iBanga 00, iBanga 0, kunye neBanga 1: Oko Kuthethwa Ngamanani KwiiMicrons

Ngaphambi kokuba uqinisekise ukuba iflethi ithambile, kufuneka wazi ukuba ufuna ntoni.

Amanqanaba okuthambeka achazwa kwimigangatho eyahlukeneyo yamazwe ngamazwe — DIN876, ASME B89, JIS, GB/T — kwaye onke ahambelana ngokweenkcazo ezifanayo ezisisiseko. Nantsi into ethethwa ngala manqanaba:

Mandiguqulele oku kube ngamanani okwenyani.

Kwipleyiti eqhelekileyo eyi-1000 × 630 mm (ubukhulu obuqhelekileyo bokuthunyelwa ngaphandle), iBanga 00 livumela ukuphambuka okupheleleyo okuthe tyaba okumalunga ne-1.5 μm kulo lonke umphezulu. Oko kumalunga ne-1/50th yobubanzi beseli ebomvu yegazi yomntu. IBanga 0 liphinda kabini elo ukuya kwi-3 μm. IBanga 1 limalunga ne-6 μm.

Nantsi into abathengi abaninzi abayiphosi: inkcazo yimitha nganye yobude bomphezulu, hayi ukuphambuka kweplate iyonke.

Ukuba uthenga ipleyiti engama-2000 × 1000 mm, ukunyamezelana kwenqanaba kusebenza ngokwahlukileyo kwimitha nganye ethe tyaba yomphezulu. Ukuphambuka kwakho okuphezulu okuvumelekileyo kubalwa ngokusekelwe kubukhulu obude. Kwipleyiti engama-2000 mm, ujonge malunga ne-2.5 μm kwiBanga 00, i-5 μm kwiBanga 0, kunye ne-10 μm kwiBanga 1.

La ngamanani onokuwalinganisa ngokwenene. Ukuba umntu ukuxelela ukuba ipleyiti yakhe ye-2000 mm Grade 00 "ine-3 microns yokwahluka" - oko kungaphakathi kwengcaciso. Ukuba bathi "malunga ne-8 microns" - loo nto yintsimi yeBanga loku-1, hayi iBanga 00.

Cacisa amanani ngaphambi kokuba utyikitye nantoni na.

Uvavanyo lwePhepha: Indlela ekhawulezayo ekufuneka wonke umntu ochwephesha ayazi

Uvavanyo lwephepha aluloukulinganisa ngokuchanekileyoKodwa yindlela ekhawulezayo yokubamba iingxaki ezicacileyo ngaphambi kokuba uchithe ixesha useta i-autocollimator.

Nantsi indlela esebenza ngayo.

Uza kuyidinga: iphepha leprinta eliqhelekileyo (i-70-80 gsm isebenza kakuhle), umphezulu wepleyiti ococekileyo, kunye nezandla ezizinzileyo.

1. Coca umphezulu wepleyiti kakuhle nge-isopropyl alcohol. Naluphi na uthuli luya kudala unxibelelwano olungeyonyani.

2. Sika imicu yephepha enobubanzi obuyi-20 mm kunye nobude obuyi-50-80 mm.

3. Beka imicu kwiindawo ezibalulekileyo kumphezulu wepleyiti — kwiikona, embindini, nakuma-diagonals.

4. Zama ukutyibiliza igeyiji yokufefa eyi-0.5 mm phantsi komcu wephepha phantsi kobunzima bayo.

Oko ukuvavanyayo ngokwenene: Ukuba umcu wephepha uyatyibilika phantsi kobunzima bawo, kukho indawo evulekileyo — oko kuthetha ukuba umphezulu wepleyiti uxinzekile ngelo xesha xa kuthelekiswa nendawo ejikelezileyo. Oku kubonisa ukuxinana okanye ukuntywila kwindawo ethile.

Umda: Olu vavanyo alunakukwazi ukulinganisa ukuphambuka okuthe tyaba. Lukuxelela kuphela ukuba umphezulu wepleyiti uyadibana na nephepha kububanzi balo bonke. Ipleyiti ingaphumelela olu vavanyo kodwa ingabi namlinganiselo weBanga 0.

Uvavanyo lwephepha luluncedo njengesango lokuqala lokupasa. Ukuba aluphumelelanga, unesizathu esikhawulezileyo sokwala okanye sokulibazisa ukuhanjiswa. Ukuba luyaphumelela, yiya kwi-autocollimator ukuze uqinisekiswe ngokwenene.

Indlela ye-Autocollimator: Indlela iingcali ezilinganisa ngayo i-Sub-Micron Flatness

Kulapho ukuqinisekiswa kuba yinto enzulu khona.

I-autocollimator ilinganisa ukuphambuka kwe-angular kumphezulu obonakalisa ukukhanya ngokuveza umqadi wokukhanya odibeneyo kunye nokulinganisa i-engile ebonakalisiweyo. Ingasombuluka iye kwi-0.1 arc-second - eguqulela kwi-0.5 μm/m kumphezulu wegranite.

Izixhobo oza kuzidinga:

• · I-optical autocollimator (i-Taylor-Hobson, i-Mahr, okanye i-Dietzgen ziimpawu eziqhelekileyo zobungcali)
• · Isibonisi esichanekileyo okanye isincamathelisi sesipili
• · Isitendi sokuxhoma esizinzileyo
• · Ulawulo lokusingqongileyo (okungakumbi malunga noku ngezantsi)

Iprotokholi yokulinganisa:

1. Vumela ipleyiti izinze kubushushu begumbi ubuncinane iiyure ezi-4 emva kokuziswa. Igranite iphendula kutshintsho lobushushu malunga ne-0.001 mm/°C. Ukuba ipleyiti ifike ibanda kwaye ivenkile yakho ishushu, linda.

2. Coca umphezulu ngokupheleleyo.

3. Misela i-autocollimator kwi-tripod ezinzileyo kwelinye icala lepleyiti.

4. Chaza igridi yakho yokulinganisa. Kwipleyiti ye-1000 × 630 mm, igridi ye-5 × 5 (amanqaku okulinganisa angama-25) iyinto eqhelekileyo. Iipleyiti ezinkulu zisebenzisa igridi elinganayo.

5. Thatha ufundo kwindawo nganye yokunqumlana kwegridi, uhambisa isibonisi phakathi kwamanqaku.

6. Bhala phantsi zonke izifundo. Bala inani elipheleleyo lezifundo ezibonisiweyo (TIR) ​​kuzo zonke iindawo.

Kwipleyiti ye-Grade 00 eyi-1000 × 630 mm, i-TIR yakho iyonke akufuneki idlule malunga ne-1.5 μm.

Iimpazamo eziqhelekileyo ezenziwa ngabathengi:

• · Ukulinganisa kwangoko emva kokuba ipleyiti ifikile (ukuhamba kobushushu)
• · Ukusebenzisa i-autocollimator yedijithali engabizi kakhulu ngaphandle kokulinganiswa okuqinisekisiweyo
• · Ukuthatha ukufundwa okungu-3-4 kuphela endaweni yegridi efanelekileyo
• · Ukungayinaki indawo yomphetho — eminye imigangatho ivumela ukunyamezelana okukhululekileyo ngaphakathi kwe-12 mm yomphetho wepleyiti, kodwa kufuneka uyibhale phantsi le nto

Ukuba ukufundwa kwe-autocollimator yakho kudlula inkcazo yenqanaba, unobungqina obubhaliweyo bebango. Musa ukusayina irisithi yokuhanjiswa.

Ukufunda iSatifikethi soLungiso oluza nayo yonke iPlate yomphezulu yeZHHIMG®

Yonke ipleyiti yomphezulu ye-ZHHIMG® ithunyelwa nesatifikethi sokulinganisa. Nantsi indlela yokuyifunda ngokuchanekileyo.

Oko kufanele kubonakale kwisatifikethi:

• · Ubungakanani bepleyiti kunye nophawu lwenqanaba

Isatifikethi sokulinganisa sidwelisa izixhobo ezithile ezisetyenzisiweyo kunye nenombolo yaso yokuqinisekisa elandelelwayo.

Iinkcukacha Ezintathu Abathengi Abazikhumbulayo Ngokufuthi - Kwaye Iindleko Zazo Xa Bezikhumbula

Emva kweminyaka yokusebenza nabathengi malunga nokwamkelwa kwepleyiti yomphezulu, ndibone ukuba ukungaziphathi kakuhle okuthathu kubangela iingxaki ezibiza kakhulu.

1. Ukungayinaki imfuneko yokuzinzisa ubushushu

I-granite inomoya ophantsi wokushisa kodwa inokwandiswa kobushushu okulinganisekayo. Ipleyiti elinganiswe kuma-20°C kumzi-mveliso efika kwindawo yokugcina impahla kuma-15°C iya kuba itshintshile. Ukuba usayina ngaphandle kokulinda ukulingana kobushushu, wamkela ipleyiti ekwimeko engaziwayo.

Ixabiso lokungayinaki: Ipleyiti yeBanga 00 kwi-thermal differential ye-5°C inokushukuma nge-5 μm/m — ngokuphindwe kalishumi kunokunyamezela kweBanga 00.

2. Ukungabhalisi ukuphambuka kwendawo yomda

Uninzi lwemigangatho (DIN876, ASME B89) ichaza ukuba tyaba phezu "kwendawo eluncedo" yepleyiti, idla ngokukhupha umda we-12 mm ukusuka emaphethelweni. Ukuba ipleyiti inemiphetho ye-chamfers okanye imicu yokunciphisa, oku kuba nzima.

Ixabiso lokungayinaki: Wamkela ipleyiti engaphumeleliyo kwi-flatness spec kwindawo esembindini esebenzisekayo, nangona isatifiketi (esilinganise iindawo zomphetho) sibonakala siphumelela.

3. Ukwamkela "ngokunyamezelana" ngaphandle kwemilinganiselo yokwenyani

Isatifikethi esithi “Ibanga 00 — PASS” ngaphandle kokubhala ukuphambuka okulinganisiweyo asiphelelanga. Ipleyiti ekwi-0.48 μm/m yiBanga 00. Ipleyiti ekwi-0.49 μm/m nayo yiBanga 00 — kodwa enye ikufutshane kakhulu nomda wokunyamezelana kunenye.

Ixabiso lokungayinaki: Awunaso isiseko sokulandelela ukushukuma ngokuhamba kwexesha. Ukuba ipleyiti ishukuma iye kwi-0.52 μm/m emva kweenyanga ezintandathu, awazi ukuba ishukume kangakanani na.

Oko Kwenziwa yiZHHIMG® Ngaphambi Kokuthunyelwa Ngakunye: Iprotokholi Yethu Yangaphakathi ye-QC

Ufanele wazi ukuba kwenzeka ntoni ngaphambi kokuba ipleyiti yakho ifike edokini lakho.

I-ZHHIMG® isebenzisa amaziko amabini okuvelisa angama-200,000 m², kunye neyadi yamatye engama-20,000 m². Ipleyiti nganye ihlolwa ngamanyathelo amaninzi ngaphambi kokuba ithunyelwe:

1. Ukulinganisa kusetyenziswa izixhobo zesisombululo seGerman Mahr eziyi-0.5 μm — umgangatho ofanayo osetyenziswa yi-PTB kunye neelabhoratri zemetrology zesizwe

2. Uqinisekiso lwesibini kusetyenziswa amanqanaba e-elektroniki e-Swiss WYLER ukuqinisekisa ukuphambuka kwe-angular

3. I-autocollimator grid scan epheleleyo — ubuncinci igridi eyi-5 × 5 kwiipleyiti ezingaphantsi kwe-1500 mm; iigridi ezinkulu kwiipleyiti ezinkulu kakhulu

4. Ukuqinisekiswa kwe-interferometer ye-laser ye-Renishaw yase-UK kuzo zonke iipleyiti zeBanga 00 — kubonelela ngovavanyo oluzimeleyo lwedatha yokusicaba

5. Ukuqinisekiswa kozinzo lobushushu — iipleyiti zilinganiswa emva kozinzo lobushushu oluphantsi kweeyure ezingama-24 kwindawo elawulwayo

6. Ukuveliswa kwesatifikethi sokulinganisa esinazo zonke ixabiso elilinganisiweyo, idatha yokusingqongileyo, kunye nezixhobo ezinokulandelelwa kumaziko esizwe e-metrology

Lo asingomgangatho weshishini. Uninzi lwababoneleli lubonelela ngomlinganiselo omnye ngaphandle kokuqinisekiswa okunqamlezileyo. I-ZHHIMG® isebenzisa ukuqinisekiswa okuphindwe kabini kwipleyiti nganye yeBanga 00 kuba "ishishini elichanekileyo alinakuba nzima kakhulu" ayisosilogeni nje - yiyo loo nto abathengi abanjengo-GE, uBosch, kunye noRexroth beqhubeka noku-odola kuthi.

Itheyibhile yokuthelekisa: Iindlela zokulinganisa ubucaba

Kubathengi abaninzi abafumana ipleyiti eqhelekileyo ye-1000 × 630 mm, ukuqinisekiswa kwe-autocollimator ngegridi eyi-5 × 5 efanelekileyo kubonelela ngokuchaneka okwaneleyo kunye notyalo-mali olufanelekileyo ngexesha elifanelekileyo.

Imibuzo ebuzwa qho

Ingakanani ithe tyaba ipleyiti yomphezulu wegranite yeBakala 00 ngamanani okwenyani?

Ibanga 00 lichaza ukuphambuka okuphezulu kokuthe tyaba kwe-≤0.5 μm/m. Kwipleyiti ye-1000 × 630 mm, oku kuvumela ukuphambuka okupheleleyo kwe-1.5 μm kumphezulu. Kwipleyiti ye-2000 mm, kuvumela malunga ne-2.5 μm. Ezi zizilinganiso ze-sub-micron ezifuna izixhobo ezifanelekileyo zokuqinisekisa.

Ndingasebenzisa umgangatho wengcali yoomatshini engabizi ukujonga ipleyiti yomphezulu wegranite?

Inqanaba lomenzi wemishini lilinganisa ukuthambeka kwe-angular, hayi ukuba tyaba. Alinakubona ukuxinana okanye amaqhuma kwindawo ethile kumphezulu weplate — kuphela ukuthambeka ngokubanzi. Musa ukusebenzisa inqanaba lomenzi wemishini njengesixhobo sokuqinisekisa ukuba tyaba. Liluncedo ekujongeni ukuba ipleyiti yakho yomphezulu ithambekile na, hayi ukuba ithe tyaba na.

Ndingenza ntoni ukuba ipleyiti ehanjisiweyo ayisebenzi ngokwemigaqo yokuthamba?

Musa ukusayina irisithi yokuhanjiswa. Bhala phantsi ukusilela ngedatha yakho yokulinganisa (ukufundwa kwe-autocollimator, iifoto, iimeko zokusingqongileyo). Nxibelelana ne-ZHHIMG® ngobungqina obubhaliweyo. Siphatha onke amabango ngokuthe ngqo ngokulungiswa kwakhona okanye ukutshintshwa phantsi kwesiqinisekiso sethu somgangatho.

Ithatha ixesha elingakanani i-autocollimator umlinganiselo ofanelekileyo kwipleyiti ye-1000 × 630 mm?

Cwangcisa imizuzu engama-45-90. Oku kuquka imizuzu engama-20-30 yokuqinisekisa ukuzinza kobushushu, imizuzu eli-15-30 yokucoca nokuseta umphezulu, kunye nemizuzu eli-15-30 yokulinganisa ngokoqobo kwigridi ye-5 × 5. Ukukhawulezisa inkqubo kuzisa impazamo.

Yintoni i-thermal drift kwaye iyichaphazela njani indlela endilinganisa ngayo?

Ukushukuma kobushushu kukutshintsha kobukhulu bepleyiti okubangelwa kukutshintsha kobushushu. Igranite ikhula malunga ne-0.001 mm nge-degree Celsius ngemitha nganye. Ukuba ipleyiti yakho yayilinganiswe kwi-22°C kodwa indawo yakho yokujonga ikwi-19°C, ubukhulu be-1000 mm butshintsha nge-3 μm — ngokuphindwe kathandathu kunokunyamezelana kweGrade 00. Soloko uvumela iiyure ezi-4+ zokulinganisa ubushushu ngaphambi kokulinganisa.

I-ZHHIMG® ijongana njani namabango ukuba ipleyiti ifunyenwe inganyamezelani?
