Nantsi umbuzo endithanda ukuwubuza abaphathi beevenkile ezichanekileyo: ugqibele nini ukuyithemba ipleyiti yakho yomphezulu?
Hayi “ibonakala ithambile.” Hayi “idlule ekuhlolweni okufikayo.” Ndithetha ukuthembakala — uhlobo lokuthemba apho ubeka khona inxalenye entsha ematshinini kuyo, usebenzise imilinganiselo yakho, uze wazi ukuba amanani owafundayo amalunga nenxalenye, kungekhona ipleyiti eshukuma phantsi kwayo.
Uninzi lwabantu luyathandabuza. Abanye bayawutshintsha umxholo. Abanye bayavuma ukuba abanalo ulwazi, kuba abazange bahlole.
Yiyo leyo indawo yokuqala yale ngxoxo yonke.
Kutheni iiPlate zoMphezulu Zisabalulekile Ngaphezu Kokuba Abathengi Abaninzi Bacinga
Siphila kwixesha le-laser interferometers, iinkqubo zokubona, kunye nee-touch probes ezinokulinganisa iimpawu ezincinci ngemizuzwana. Kulula ukuphatha ipleyiti yomphezulu njengentsalela - ilitye elisicaba elinzima (okanye iqhekeza elinzima lesinyithi esisicaba) elihlala kwikona yegumbi lokuhlola elingenzi nto phantse.
Ngaphandle kokuba yenza phantse yonke into.
Ipleyiti yomphezulu yindawo yokubhekisa apho kwenziwa khona uninzi lweemilinganiselo zesandla kunye neze-semi-manual. Ukufundwa kwe-micrometer nganye oyithathayo nge-height gauge, yonke indlela yokuseta isalathisi sovavanyo, yonke into ethelekiswayo phakathi kwesixhobo somsebenzi esenziwe ngomatshini kunye nomgangatho wokubhekisa — konke kuhamba kumphezulu indawo ehleli kuwo. Ukuba loo mphezulu awuzinzanga ngokwejometri kwaye awuqikeleleki ngokobushushu, yonke imilinganiselo esezantsi komlambo inempazamo ethile engalinganiswanga.
Inyaniso engathandekiyo kukuba uninzi lweevenkile lusebenzisa ulawulo lomgangatho kwiziseko ezingakhange zibuzwe kangangeminyaka. Ngamanye amaxesha amashumi eminyaka.
I-Cast Iron vs. Granite: Uthelekiso Lokwenyani Akukho mntu Wenza Ngokufanelekileyo
Ngena kwiindawo ezilishumi zokwenza izinto ngobuchule kwaye uza kufumana umahluko omalunga ne-50/50 phakathi kweepleyiti zesinyithi esityhidiweyo kunye negranite surface. Buza abathengi ukuba kutheni bekhethe into abayikhethileyo, kwaye uninzi lwabo luya kukunika impendulo evakala inengqondo kodwa engenakuphononongwa.
"Ndikhethe isinyithi esityhidiweyo kuba sesemveli."
"Ndikhethe igranite kuba izinzile ngakumbi."
Zombini ezo mpendulo aziphelelanga. Nantsi indlela ebonakala ngayo inkqubo yokwenyani yesigqibo:
Iipleyiti zesinyithi eziphosiweyoibingumgangatho wemizi-mveliso kangangeminyaka engaphezu kwekhulu, kwaye ngezizathu ezilungileyo. Zineempawu ezintle zokudambisa — zifunxa ukungcangcazela ngcono kunegranite, nto leyo ebalulekileyo kwiindawo ezinzima zoomatshini. Kulula kwakhona ukuziphinda zivele xa zinxitywa. Ingcali yoomatshini inokuyikrwela ipleyiti yomphezulu wesinyithi esidala ibuyele kwimimiselo ngokukhawuleza, nto leyo eyenza ukulungiswa kube lula.
Ingxaki kukuba i-thermal sensitivity iyakhula kwaye inciphe ngokuphawulekayo xa kutshintshwe ubushushu. I-cast iron plate kwivenkile engafudunyezwanga ebusika iziphatha ngendlela eyahlukileyo ngokwejometri kune-plate efanayo ehlotyeni. Kumsebenzi ofuna ukuchaneka kwe-micron kwimilinganiselo emikhulu, olu tshintsho lobushushu alunamsebenzi.
Iipleyiti zomphezulu wegraniteSombulula ingxaki yobushushu ngobuhle. I-granite emnyama ine-coefficient yokwandisa ubushushu ephantsi kakhulu kunye nozinzo olukhethekileyo kumanqanaba obushushu aqhelekileyo okusebenza. Ipleyiti ye-granite ayidingi lawulo lwemozulu ukuze ibambe i-geometry yayo ngendlela intsimbi ephosiweyo eyenzayo. Ayinakubanda, ayigqwali, kwaye ayifuni ioyile.
Ingxaki kukuba i-granite iyalungiseka. Xa umphezulu we-granite ubola okanye wonakele, awunakuyikrwela ngendlela onokuyenza ngayo ngentsimbi ephoswe ngentsimbi. Ujonge ukuphinda uyifake (ibiza kakhulu kwaye ithatha ixesha) okanye ukuyitshintsha. Yingakho umgangatho wokuqala wezinto kunye nokuchaneka kokwenziwa kwento kubaluleke kakhulu kwi-granite - wenza isibophelelo sexesha elide xa uthenga.
Eyona nto ibalulekileyo kweli candelo: kwiindlela ezininzi zokuhlola kwiindawo ezilawulwayo, ukuzinza kobushushu begranite kuyinika umda olinganisekayo. Kwimishini enzima kunye nokuhlanganiswa okukhulu apho ukungcangcazela kunye nokulungiswa kubalulekile, isinyithi esityhidiweyo sisafumana indawo yaso.
Inkcazo yeNkqubo yamaBanga: Oko Ukuthengayo
Uninzi lweenkcazo zepleyiti yomphezulu zibhekisa kwimigangatho efana ne-DIN 876, ASME GGGP-463C, okanye i-ISO 8512. Le migangatho ichaza amanqanaba okuchaneka — ngesiqhelo kwiBanga 00, kwiBanga 0, kwiBanga 1, nakwiBanga 2 — ngokusekelwe ekunyamezeleni ukuthamba.
Nantsi into ethethwa ngala mabanga xa usebenza, usebenzisa umgangatho we-DIN 876 njengesalathiso:
Ibanga 00 livumela malunga ne-2.3 microns yokuphambuka okuthe tyaba ngaphezulu kwe-1,000mm. Ibanga 0 livumela malunga ne-4.6 microns. Ibanga 1 livumela malunga ne-9.2 microns. Ibanga 2 livumela malunga ne-18.5 microns.
Loo ndlela yokuphinda-phinda ayisiyonto ingaqhelekanga — inyathelo ngalinye elisezantsi kwinqanaba limele ukuphinda-phinda kwempazamo evumelekileyo. Kwaye loo mali yempazamo ayifanele igubungele nje kuphela ukunyamezelana kokwenziwa, kodwa nokonakala kwepleyiti ngexesha lokusebenza kwayo.
Kwimeko: ukuba ulinganisa izinto ezisetyenzisiweyo kwi-±2 microns, ipleyiti yomphezulu yeBanga loku-1 (ii-9.2 microns zokuphambuka okuvumelekileyo kokuthe tyaba) sele itya phantse i-20% yebhendi yakho yokunyamezelana iyonke — ngaphambi kokuba ucinge nangayiphi na enye indlela yokulinganisa ukungaqiniseki. Elo linani elifanelekileyo lokuhlala nalo.
Yingakho iilebhu zemetrology ezinzulu kunye neenkqubo zomgangatho weenqwelo moya ziphantse zichaze iBanga 00 ngokubanzi. Ixabiso elongezelelweyo lepleyiti yomgangatho ophezulu lincinci xa lithelekiswa nexabiso lempazamo yokulinganisa engabonwanga ewela kwiqela leendawo ezingahambelaniyo.
Yintoni Ebulele Ipleyiti Yakho Yokugqibela Yomphezulu (Kwaye Ezilungileyo Ziyakuthintela)
Iipleyiti zomphezulu aziphazami kakhulu. Ziyashukuma. Zifunxa umswakama. Ziqokelela umonakalo ongaphantsi komhlaba ovela kwiimpahla zokusebenza eziwileyo. Ziphuhlisa iipateni zokuguguleka ezikwindawo ethile ngokudibana okuphindaphindiweyo neendawo ezifanayo zokulinganisa.
Eyona ndlela ixhaphakileyo yokusilela kwiipleyiti zesinyithi eziphothiweyo kwiindawo ezifumileyo kukutshintsha kobukhulu obubangelwa kukufuma. Nokuba i-oyile isetyenziswa ngokufanelekileyo, isinyithi esiphothiweyo sinemingxuma eyaneleyo yokufunxa umphunga wamanzi ngokuhamba kwexesha, ingakumbi kwiindawo ezingenalawulo lwemozulu. Isiphumo kukulahlekelwa kancinci, okuhambayo kokusicaba okungabonakali kwisatifikethi sokulinganisa kodwa kubonakala ngalo lonke ixesha uzama ukubamba ukunyamezelana okuqinileyo.
Iipleyiti zegranite ziyasilela ngokwahlukileyo. Eyona ngxaki ixhaphakileyo asikokuba yingxaki yomgangatho wegranite — yingxaki yokutshayiswa bubushushu. Ipleyiti yomphezulu wegranite ebihleli kwindawo yokugcina izinto ebandayo yaze yafuduselwa kwigumbi lokuhlola elifudumeleyo nelifumileyo inokufumana uxinzelelo lwendawo ethile oludala imifantu emincinci kumphezulu ongaphantsi komhlaba. Oku akwenzeki ngokuqhelana ngokufanelekileyo, kodwa kwihlabathi lokwenyani, izinto ziyashukuma ngokukhawuleza.
Enye indlela yokusilela kwezi zinto zombini kukonakala kwempembelelo. Isiqwenga somsebenzi sentsimbi esiwileyo, ukubekwa ngokungakhathali kwebhloko enzima yegeyiji - ezi zenza ii-dents zasekuhlaleni okanye iimpawu ze-chip eziba zi-stress concentrators kunye neempazamo ze-geometric reference. Iipleyiti ezilungileyo zomphezulu ziza nee-protective workpiece carriers ngokukodwa ukuthintela oku, kwaye uninzi lwabasebenzi aluyinaki ingcebiso de babe sele bedale ingxaki.
Inkqubo Yezinto Ezingenamsebenzi Ekungekho Mntu Uthetha Ngayo
Ipleyiti yomphezulu ehleli kwisitendi esingalinganiyo kakuhle yipleyiti yomphezulu eyonakeleyo. Isitendi, indlela yokusifaka, kunye nokusingqongileyo konke oku kunegalelo ekusebenzeni kakuhle kwepleyiti.
Kwiipleyiti zesinyithi ezibunjiweyo, indlela yendabuko kukubeka ikhabhinethi eneenyawo ezilungelelanisiweyo. Ingcinga kukufaka ipleyiti kwimizuzu embalwa ukusuka kwinqanaba, uze uvumele ubunzima bepleyiti busasaze naluphi na ukungalingani okushiyekileyo. Oku kusebenza kakuhle, kodwa kuthatha ukuba umgangatho uqinile kwaye awuguquguquki phantsi komthwalo.
Kwiipleyiti zegranite, ingakumbi iipleyiti ezinkulu, isakhiwo esiqinileyo nesixhasayo se-monolithic sibaluleke ngakumbi. Igranite iqinile kodwa iyaphuka - ayiguquguquki ukuze ivumelane nokungalingani kwesiseko okuncinci ngendlela isinyithi esibunjiweyo esenza ngayo. Ipleyiti yegranite exhaswe kwisiseko esingalinganiyo iya kuba noxinzelelo olwahlukileyo olunokubangela ukuqhekeka, ingakumbi ukuba kukho imijikelo yobushushu ebandakanyekayo.
Izixhobo ezibalulekileyo ngokwenene: izithwali ezifanelekileyo zomsebenzi ukuthintela umonakalo obangelwa yimpembelelo, izigqubuthelo zesiciko ukugcina inkunkuma kunye nongcoliseko lungangeni kumphezulu wokulinganisa, kunye neesatifikethi zokulinganisa rhoqo ezivela kwilabhoratri evunyiweyo. Ipleyiti engenasatifikethi sokulinganisa sangoku yenza izithembiso zokuba ayinakuze ikwazi ukuxhasa.
Ukufumana Izinto Ezivela Kumenzi Wokwenene vs. Umthengisi Wekhathalogu
Oku kubaluleke ngaphezu kokuba uninzi lwabathengi luqonda.
Xa uthenga ipleyiti yomphezulu kumsasazi othenga kwiifektri ezininzi, uhlala ufumana imveliso enephepha elichazayo kodwa ingenambali yokwenyani yokwenziwa kwayo. Awazi ukuba ngubani owayenzayo, zeziphi izinto ezisetyenzisiweyo, okanye ukuba umntu owakrwela umphezulu wokugqibela wayenamava eminyaka emithathu okanye amashumi amathathu.
Umahluko ubonakala kwindlela esebenza ngayo imiphetho, ukuhambelana kobume bomphezulu, kunye nokugcinwa kokuthamba kwexesha elide. Ipleyiti yomphezulu evela kumenzi ochanekileyo onamava okukrwela ngesandla amashumi eminyaka iya kuyigcina ixesha elide ijiyometri yayo kuba umphezulu wokuqala wenziwe ngononophelo ngakumbi. Ipleyiti evela kumthengisi wempahla inokuhlangabezana nenkcazo yokuthamba xa ihanjiswa - kodwa emva kweenyanga ezintandathu, kwindawo yokwenyani yefektri, umsantsa phakathi kwazo ulinganiswa.
Buza umthengisi wakho ngokuthe ngqo: Ngubani owenze oku? Phi? Ndingatyelela indawo? Bangaphi iminyaka yamava okukrwela abaqhubi bakho? Ingaba ikhonkco lakho lokulinganisa libonelela ngokulandelela okungakanani?
Ababoneleli abangavumiyo ukuphendula loo mibuzo bakuxelela into ethile.
Ukwenza Ukhetho Oluchanekileyo kwiSicelo Sakho
Isigqibo asikokuba intsimbi ephosiweyo okanye igranite ifaneleke ngokwenene. Simalunga nokufanisa izinto kunye nomgangatho wazo ngokweemfuno zakho zokwenyani.
Ukuba usebenzisa ilebhu yokulinganisa enemithetho engqongqo yokusingqongileyo kunye neemfuno zokunyamezelana kwenqanaba le-micron: chaza i-granite yeBanga le-00, enokulandelela ukulinganiswa kwe-calibration kwiziko le-metrology likazwelonke, kunye noluhlu olubhaliweyo lokusebenza kobushushu kunye nokufuma.
Ukuba usebenzisa indawo yoomatshini bokuvelisa enezixhobo ezinzima kunye nokungcangcazela okukhulu komgangatho: ipleyiti yesinyithi esixhaswe kakuhle ene-vibration damping efanelekileyo inokwenza ngcono kune-granite, kuba ukufunxwa kokungcangcazela kubaluleke ngaphezu kozinzo lobushushu kuloo meko.
Ukuba ukwimeko yemozulu yaseMzantsi-mpuma Asia engenamoya opholileyo kwindawo yemveliso: ukumelana nokufuma kwegranite akunyanzelekanga. Ngumahluko phakathi kwepleyiti egcina ijiyometri yayo unyaka wonke kunye neleyo ishukuma rhoqo ngexesha lemvula.
Ukuba uthenga inkqubo yezonyango okanye yomgangatho wenqwelomoya: funa amaxwebhu apheleleyo okulandeleka, izatifikethi zokulinganisa ezivunyiweyo, kunye nomvelisi onamava abhaliweyo kuloo macandelo alawulwayo. Iinkcukacha zokuthengwa zibaluleke kakhulu njengeenkcukacha zemveliso.
Yintoni Elandelayo Emva Kwesi Sitya
Nantsi into uninzi lwabathengi beepleyiti ze-surface abangayicingiyo de kube sekwephuzile: ipleyiti ye-surface ithembeke kuphela njengenkqubo eyijikelezileyo.
Igeyiji yakho yokuphakama kufuneka ilinganiswe. Izalathi zakho zovavanyo kufuneka zibe kwimeko entle yoomatshini. Ukujonga kwakho ubushushu kunye nokufuma kufuneka kube kwangoku. Iingcali zakho kufuneka ziqonde indlela yokuqwalasela ukwanda kobushushu xa zilinganisa izinto ezikubushushu obahlukileyo kunepleyiti.
Ipleyiti yomphezulu wegranite yeBanga 00 ayikuniki ngokuzenzekelayo iziphumo zokulinganisa zeBanga 00. Ikunika ireferensi ethembekileyo. Ezinye izinto eziseleyo zetsheyini yokulinganisa nazo kufuneka zakhiwe ngokuchanekileyo.
Oko kufanelekile ukukhumbula kwixesha elizayo xa umntu ekubuza ukuba uyayithemba na ipleyiti yakho yomphezulu. Impendulo mhlawumbi ithi “ayiyiyo ngokupheleleyo” — kwaye isisombululo mhlawumbi siqala ngokujonga yonke inkqubo, kungekuphela nje ipleyiti ngokwayo.
Kodwa ngokuqinisekileyo kuqala ngokuthenga ipleyiti efanelekileyo kwasekuqaleni.
