Kwihlabathi le-metrology yemizi-mveliso, ii-granite surface plates zihlala zitsala indawo yokuqaqamba kwazo okumangalisayo kunye nokuzinza kobushushu kwiindawo zelebhu ezilawulwayo. Nangona kunjalo, xa siphuma kwindawo ecocekileyo yelebhu yokulawula umgangatho size singene kumgangatho oqinileyo noguquguqukayo wesityalo esikhulu sokwenza imveliso, iimfuno zesixhobo sokubhekisa ngokuchanekileyo zitshintsha kakhulu. Kulapho ii-cast iron surface plates (ezidla ngokubizwa ngokuba luhlolo lwe-cast iron okanye amaqonga ovavanyo) zingqina khona ixabiso lazo. Nangona zisenokungahambelani rhoqo nokunyamezelana okuncinci kakhulu kwe-granite yelebhu, indibaniselwano yazo eyahlukileyo yokuqina, ukuxinana kokungcangcazela, kunye nomthamo wokuthwala umthwalo kuzenza zibe lolona khetho lubalaseleyo lokuhlolwa kwemizi-mveliso okunzima.
Ukudambisa ukungcangcazela okungenakuthelekiswa nanto kwiindawo eziguquguqukayo
Esinye sezizathu ezibalulekileyo zokukhetha ipleyiti yomphezulu wesinyithi kwindawo yemizi-mveliso kukwazi kwayo ukudambisa ukungcangcazela. Kwiworkshop exakekileyo egcwele iiforklifts, ii-stamping presses, kunye noomatshini be-CNC, ukungcangcazela okujikeleze umhlaba yinto ehlala isenzeka enokubangela umonakalo kwiimilinganiselo ezinobuzaza.
Isinyithi esixonxiweyo, ngakumbi isinyithi esingwevu esinamandla kakhulu (esidla ngokuba ngama-HT200 ukuya kwi-HT300), sinolwakhiwo olukhethekileyo olune-graphite ye-flake. Olu lwakhiwo lwangaphakathi lunika isinyithi esixonxiweyo i-coefficient yokufuma ephindwe ka-6 ukuya kwi-10 kuneyentsimbi. Ngokusisiseko, izinto zisebenza njengesixhobo sokufunxa uthuselo lwendalo, zichitha ngokukhawuleza amandla avela kwiintshukumo zangaphandle okanye kwiimpembelelo zangaphakathi. Kubahloli abalinganisa izinto ezinkulu, ezinzima okanye izixhobo zokuvavanya ezisebenza ngamandla, ipleyiti yesinyithi esixonxiweyo inika isiseko "esithuleyo," esizinzileyo esiqinisekisa ukuba ukufundwa komlinganiselo kuhlala kuchanekile nokuba kwindawo yeworkshop enengxolo.
Amandla kunye noBulukhuni obuPhezulu bokuthwala imithwalo
Ukuhlolwa okunzima kudla ngokubandakanya ukubeka izinto ezinkulu zokusebenza—ezifana neebhloko zeenjini, ii-turbine housings, okanye iifreyimu ezinkulu ezidityanisiweyo—kumphezulu wesalathiso. Kulapho iimpawu zoomatshini zesinyithi esityhidiweyo zikhanya khona ngokwenene.
Iipleyiti zomphezulu wesinyithi zenziwe ngendlela yokuba zibe namandla amakhulu. Njengoko amandla oxinzelelo afikelela kwi-200-300 MPa kunye nobunzima bomphezulu obuqhelekileyo phakathi kwe-HB170 kunye ne-HB240, zinokuxhasa ngokulula imithwalo eqala kwiitoni ezininzi ukuya kwiitoni ezininzi ngaphandle kokuguquka. Abavelisi badla ngokuphucula obu buchule ngokuyila iipleyiti ngesakhiwo esifana nebhokisi esiqiniswe yigridi yeembambo zangaphakathi (ezihlala zilungiswa kusetyenziswa uhlalutyo lwezinto ezilinganiselweyo). Olu yilo lukhulisa ukuqina ngelixa lugcina ubunzima bulawuleka, luqinisekisa ukuba umphezulu uhlala uthe tyaba nokuba uphantsi koxinzelelo oluqatha, oluxineneyo.
Ngaphezu koko, ngokungafaniyo negranite, enokuba buthathaka kwaye ithambekele ekuqhekekeni okanye ekuqhekekeni xa ibethwe yinxalenye yesinyithi esinzima, isinyithi esityhidiweyo siqinile kakhulu kwaye asichaphazeleki. Singakwazi ukumelana nokuqhekeka okungenakuphepheka, ukuwa, kunye nokutshayiswa kumgangatho wemveliso ngaphandle kokulimala kakhulu. Ukongeza, isinyithi esityhidiweyo simelana kakhulu nokuguguleka. Inkqubo yokukrwela ngesandla esetyenziselwa ukugqiba iipleyiti zesinyithi ezichanekileyo kakhulu idala iipokotho ezincinci kumphezulu ezinokubamba inani elincinci leoyile, zibonelela ngokuthambisa kwendalo kwaye ziqinisekise ukuba ipleyiti igcina ukuchaneka kwayo kwiminyaka emininzi yokutyibilika kwiindawo ezinzima kuyo.
Ukuguquguquka kwezinto ezisetyenziswa xa kudityaniswa izinto kunye nokuhlanganiswa kwazo
Kwimizi-mveliso enzima, ukuhlolwa akubikho nje ekubekeni inxalenye etafileni ethe tyaba. Kudla ngokubandakanya ukuseta okuntsonkothileyo, ukubotshwa, kunye nokuqinisekiswa kwendibano. Iipleyiti zomphezulu wesinyithi ezibunjiweyo zibonelela ngomgangatho wokuguquguquka okusebenzayo okungenakulinganiswa nelitye eliqinileyo okanye iipleyiti zesinyithi.
Umphezulu wepleyiti yesinyithi esityhidiweyo unokulungiswa ngokulula ukuze uquke ii-T-slots, ii-U-slots, okanye imingxunya enemisonto. Ezi mpawu zivumela abahloli kunye neengcali zokuhlanganisa ukuba basebenzise ii-T-bolts kunye nee-clamps ukuze babophe ngokukhuselekileyo izinto zokusebenza, izixhobo, okanye nezixhobo zokuvavanya ngqo kwipleyiti. Olu buchule "bokulungisa i-datum plus" lubaluleke kakhulu. Luthintela iindawo ezinzima okanye ezimile ngendlela engaqhelekanga ukuba zingatshintshi ngexesha lokulinganisa, luphucula kakhulu ukhuseleko kunye nokusebenza kakuhle. Nokuba kukulungelelanisa ibhokisi enkulu yegiya, ukuseta injini yokuvavanya ukusebenza, okanye ukusebenza njengesixokelelwano sokuwelda esizinzileyo, ipleyiti yesinyithi esityhidiweyo iguquka ukusuka kwisixhobo sokulinganisa esilula ukuya kwibhentshi yokusebenza yemizi-mveliso enemisebenzi emininzi.
Uzinzo Lwexesha Elide Ngokwenziwa Kwemveliso Okungqongqo
Ingcamango ephosakeleyo eqhelekileyo kukuba isinyithi esityhidiweyo sithambekele ekugobeni. Nangona kunjalo, iipleyiti zesinyithi ezisemgangathweni ophezulu zoshishino zidlula kwiinkqubo zokuvelisa ezingqongqo ezenzelwe ngokukodwa ukuphelisa le ngozi.
Ukuqinisekisa uzinzo lwejometri ixesha elide, abavelisi abaziwayo babeka ezi castings phantsi konyango olungqongqo lokwaluphala. Oku kudla ngokubandakanya indibaniselwano yokwaluphala okwenziwayo (ukutsalwa kumaqondo obushushu aphakathi kwama-600°C nama-700°C) kunye nokwaluphala kwendalo (okuvumela ukuba i-castings iphumle ngaphandle iminyaka emi-2 ukuya kwemi-3). Ezi nkqubo zinciphisa ngaphezulu kwama-90% oxinzelelo lwangaphakathi oluvela ngexesha lenkqubo yokubumba. Ngenxa yoko, ipleyiti yesinyithi ephekwe ngokufanelekileyo iyamelana kakhulu nokuguquguquka ngokuhamba kwexesha, igcina ukuchaneka kwayo amashumi eminyaka.
Enye inzuzo ecacileyo yesinyithi esityhidiweyo kukulungiswa kwaso. Ukuba ipleyiti yegranite yonakele, kudla ngokuba nzima okanye akunakwenzeka ukuyilungisa. Ngokwahlukileyo koko, umphezulu wesinyithi ogugileyo okanye owonakele kancinci unokubuyiselwa kwimo yawo yokuqala yomzi-mveliso ngenkqubo ebizwa ngokuba yi-re-scraping. Olu buchule bokuhlaziya umphezulu buyandisa kakhulu ubomi besixhobo, nto leyo eyenza ukuba sibe lutyalo-mali olungabizi kakhulu kuyo nayiphi na indawo yemizi-mveliso.
Isiphelo: Ukuthelekisa isixhobo nomsebenzi
Ukukhetha ipleyiti yomphezulu efanelekileyo kuthetha ukufanisa iimpawu zezinto ezisetyenzisiweyo nendawo yakho yokusebenza. Ukuba umsebenzi wakho uxhomekeke kwilebhu ye-metrology elawulwa bubushushu efuna ukuchaneka kwe-sub-micron kwiindawo ezibuthathaka, i-granite iselukhetho oluhle kakhulu.
Nangona kunjalo, xa imisebenzi yakho yokuhlola isiya kumgangatho wemizi-mveliso onzima—apho ukungcangcazela kuhlala kuhleli, izinto zokusebenza zinobunzima obuziitoni, kunokwenzeka ukuba kubekho iimpembelelo, kwaye kufuneka izinto ezintsonkothileyo—iipleyiti zomphezulu wesinyithi eziphosweyo zezona zintshatsheli zingenakuphikiswa. Umthamo wazo oqinileyo wokuthwala umthwalo, ukudambisa ukungcangcazela okugqwesileyo, ulungelelwaniso oluguquguqukayo lwe-T-slot, kunye nokuqina okumangalisayo kuzenza zibe “ligxalaba lesinyithi” elifanelekileyo kushishino olunzima. Ngokutyala imali kwiqonga lokuhlola isinyithi esiphosweyo elikumgangatho ophezulu, uqinisekisa isiseko esizinzileyo, esithembekileyo, nesihlala ixesha elide semingeni yakho yokuvelisa nokuvavanya enzima kakhulu.
