Mapureti eGranite vs. Cast Iron Surface: Ndeipi Yakanakira Metrology Lab Yako?

Zvinhu zvose izvi zvave zvichishanda muindasitiri yekugadzira zvinhu kwemakore anopfuura zana, uye zvese zvine zvakanakira zvakasiyana zvinoita kuti zvive zvepamusoro mukushandiswa kwazvo. Kunyange zvazvo granite ichiwanzorumbidzwa semambo wekugadzikana uye kururama, simbi yakakandwa inoramba iri simbi inoshanda pasi peindasitiri. Kunzwisisa hunhu hwe "Granite vs. Cast Iron" kwakakosha pakuona kuti rabhoritari yako ine chishandiso chakakodzera chebasa racho, ichienzanisa kudiwa kwekururama kwemazinga e nanometer nekushanda kwakaoma kwekuongorora kwakasimba.

Mapureti epamusoro egranite, anowanzogadzirwa negranite nhema yepamusoro kana diabase, ave ndiwo mwero wepamusoro wemarabhoritari emazuva ano emetrology. Chinonyanya kukwezva granite chiri munhoroondo yayo ye geology. Matombo aya anoumbwa kwemamiriyoni emakore, achikura zvechisikigo izvo zvinobvisa zvinonetsa mukati. Kana mugadziri akacheka nekupukuta bhuroko regranite, anenge achishanda nezvinhu zvatove nemamiriro ezvinhu akafanana. Kugadzikana kwechisikigo uku kunoreva kuti granite plate inodzivirira zvikuru kutenderedza kana kumonyoroka nekufamba kwenguva, chero bedzi ikatsigirwa nemazvo.

Chimwe chezvakanakira zvikuru zvegranite murabhoritari kugadzikana kwayo mukupisa. Panyaya yekuyera nemazvo, tembiricha ndiyo muvengi. Simbi dzinokura uye dzinodzika nekupisa, uye kunyangwe kuchinja kudiki kwetembiricha yerabhoritari kunogona kukonzera kuti ndiro yesimbi ikure zvakakwana kuti ibvise zviyero zvinonzwisisika. Granite ine coefficient yakaderera yekuwedzera kwekupisa—yakaderera zvakanyanya pane yesimbi yakakandwa. Izvi zvinoreva kuti kana tembiricha iri munzvimbo yako ikachinja-chinja nemadhigirii mashoma, ndiro yegranite icharamba isina kuchinja, ichichengetedza kururama kwekuverenga kwako. Hunhu uhwu hunoita kuti granite ive sarudzo yakakodzera kune nzvimbo uko kuchengetedza tembiricha yakakwana (nguva dzose) kwakaoma kana kuti kunodhura.

Uyezve, granite ichinhu chisina simbi, icho chinounza mabhenefiti maviri akasiyana: haina magineti uye haiparadzwe nengura. Munzvimbo yekurabhoritari umo zvinhu zvemagetsi kana magineti zvinoshandiswa, ndiro yesimbi inogona kukonzera kukanganiswa. Granite, sezvo isina makemikari, haizombofi yakaita ngura. Izvi zvinobvisa kudiwa kwekushandisa mafuta anodzivirira nguva dzose anodiwa pamapuleti esimbi. Plate yegranite inogona kuchengetwa yakachena uye yakaoma, zvichideredza njodzi yekusvibisa zvikamu zviri kuyerwa. Kana mvura ikadururwa paplate yegranite, inogona kupukutwa pasina kutya ngura, nepo kudururwa kumwe chete paplate yesimbi kunogona kukonzera maburi uye kukuvara zvachose kana ikasagadziriswa nekukasika.

Kupera kwepamusoro kweplate yegranite ndeimwe nzvimbo kwainobudirira. Kuburikidza nemaitiro epamusoro ekukwesha nekupukuta, granite inogona kuwana kupera kwakafanana negirazi kwakapfava zvinoshamisa. Kutsetseka uku kunoderedza kukweshana kwezvishandiso zvekuyera zvinotsvedza uye kunoita kuti pasave nemisoro midiki nemipata yekubata ivhu kana marara. Kana pamusoro pegranite pakarohwa kana kukuvara—semuenzaniso, kana chikamu chinorema chikadonhedzwa netsaona—chinhu chacho chinowanzo pwanyika kana kuumba depression. Chinonyanya kukosha ndechekuti, hachiumbi "burr" kana mupendero wakasimudzwa wakakomberedza nzvimbo yakaroverwa. Mu metrology, depression yakasimudzwa inotyisa nekuti inosimudza mudziyo wekuyera, zvichikonzera kuverenga kwenhema pamusoro pese. Depression iri mugranite iri nyore kupatsanura uye kazhinji haina simba rakawanda pakusatsetseka kwenzvimbo yakapoteredza.

Kunyange zvazvo granite iri panzvimbo yekurabhoritari yakanyatsogadzirwa, mapurati esimbi akaumbwa anoramba akasimba munzvimbo dzekuongorora maindasitiri, dzimba dzezvishandiso, uye munzvimbo dzekugadzira zvinhu zvinorema. Pfungwa huru yesimbi yakaumbwa ndeyekuti yakasimba sei. Simbi yakaumbwa isimbi yakaumbwa isingasviki kana ichienzaniswa nematombo asina kusimba. Inogona kutsungirira kuvhunduka kukuru uye kupwanyika pasina kuputsika. Muworkshop ine vanhu vakawanda umo zvinhu zvinorema, weldments, kana zvikamu zvesimbi zvinowanzoiswa patafura yekuongorora, granite plate inogona kutsemuka pasi pekumanikidzwa. Zvisinei, ndiro yesimbi yakaumbwa ichatora kuvhunduka.

Kugadziriswa kwesimbi yakakandwa kunowanzo nzwisiswa zvisirizvo. Kunyange zvazvo chiri chokwadi kuti simbi inoda kudzivirirwa kubva kungura, ndiro yesimbi yakakandwa inochengetwa zvakanaka inogona kugara kwemakumi emakore. Nzira yechinyakare yekuchengetedza ndiro idzi inosanganisira kuchengetedza firimu rakatetepa remafuta pamusoro. Mafuta aya haangodziviriri ngura chete asiwo anoshanda semafuta ekuisa zvikamu zvinotsvedza. Pamusoro pezvo, pamusoro pendiro yesimbi yakakandwa inowanzo "kwerwa" nemaoko. Maitiro aya emaoko anogadzira maitiro ehomwe diki pamusoro. Homwe idzi hadzina kukanganisa; dzinoshanda. Dzinoshanda senzvimbo dzekuchengetera mafuta uye dzinobata chero guruva kana swarf ingave iripo, dzichidzivirira kuti isakanganise kuyerwa. Chiito ichi "chekukwiza" chinobvumira mhando chaiyo yemhinduro yekubata iyo vazhinji vekare vemachina nevaongorori vanosarudza.

Chimwe chinhu chakanaka chesimbi yakakandwa ndechekuti inogona kugadziriswa. Kana ndiro yesimbi yakakandwa ikasakara kana kukuvara, inogona kukweshwa kana kukuyiwa zvakare kuti idzorere kururama kwayo kwepakutanga. Iri ibasa rehunyanzvi, asi rinobvumira ndiro yakakandwa kuti idzoke kuhupenyu, zvichireva kuti ichagadzirisa hupenyu hwayo hwekushanda. Kusiyana neizvi, kunyange zvazvo granite ichigona kukwidzwazve, maitiro acho akasiyana uye kazhinji anoda michina yakasarudzika kuti idzokezve dombo. Kune vazhinji vanoshandisa maindasitiri, kugona kungokwesha ndiro kuti idzokere pakadzikama mumba kana munharaunda ibasa guru rekushandisa.

Mutengo wacho unokoshawo zvikuru. Kazhinji, mapurati esimbi akaumbwa nesimbi haadhure zvakanyanya kugadzira kupfuura mamwe mapurati esimbi akaumbwa nesimbi, kunyanya kana akaumbwa nesimbi dzakakura. Kunyange zvazvo mabhuroko makuru esimbi akaumbwa nesimbi aripo, mari yekuwana nekugadzira matombo makuru asina kana mhosva inogona kuva yakawanda. Simbi yakaumbwa nesimbi inogona kuumbwa muchimiro chakakura, chakaoma kunzwisisa, kusanganisira chine T-slots, icho chakakosha pakubatanidza midziyo mikuru. Kuchinja-chinja uku kunoita kuti simbi yakaumbwa ive sarudzo inofarirwa pakugadzira nekubatanidza simbi, uko simbi yacho inoshanda sebhenji rebasa pamwe chete nechishandiso chekuyera.

Pakusarudza pakati pegranite nesimbi yakakandwa murabhoritari yako yemetrology, unofanirwa kutarisa kupfuura zvinhu zvacho wofunga nezvekushandiswa kwazvo. Kana chinhu chako chikuru chiri kunyatsojeka zvakanyanya—senge murabhoritari yekuongorora, imba yeCMM, kana nzvimbo yekuongorora yemaziso—granite ndiyo inonyanya kusarudzwa. Kusagadzikana kwayo nekuchinja kwetembiricha, kushaya kupindira kwemagineti, uye zvinodiwa zvishoma zvekugadzirisa zvinogadzira nzvimbo yakagadzikana yemidziyo inobatwa neganda. Chokwadi chekuti haina ngura zvinoreva kuti unogona kushanda munzvimbo yakachena yekamuri usinganetseki nezvemafuta kana ngura zvinosvibisa zvigadzirwa zvako.

Zvisinei, kana "rabhoritari" yako iri nzvimbo yekuongorora pasi mukati mechitoro chemichina, kana kuti uri kuongorora zvinhu zvinorema, simbi yakakandwa inogona kunge iri mhinduro inoshanda. Njodzi yekudonhedza chikamu chesimbi inorema pagranite plate idambudziko iro vatariri vezvitoro vazhinji vanosarudza kudzivirira. Kugara kwenguva refu kwesimbi, pamwe chete nemutengo wayo wakaderera wekutanga uye kugona kuigadzirisa kuburikidza nekukwesha, kunoita kuti ive chinhu chakasimba munzvimbo yakaoma. Uyezve, kana maitiro ako ekuongorora achisanganisira zvikamu zvinorema zvakawanda zvinotsvedza kana kuti achida kushandisa maclamps ne fixtures, hunhu hwekuzvizora hwesimbi yakakweshwa uye kuwanikwa kweT-slots zvinopa mabhenefiti anoshanda ayo matombo asingakwanise kuenzana nawo.

Zvakakoshawo kuziva nezvenzira ye "hybrid". Nzvimbo dzakawanda dzepamusoro dzinoshandisa zvese zviri zviviri. Dzinogona kushandisa tafura hombe yesimbi yakakandwa pakugadzirisa kwekutanga uye kurongedza zvikamu zvinorema, uye dzobva dzaendesa chikamu chacho kuplate yegranite yakatsaurirwa kuti chiyereswe neunyanzvi hwekupedzisira. Kushanda uku kunowedzera simba rezvinhu zvese zviri zviviri: kusimba kwesimbi pakushanda zvakaoma, uye kugadzikana kwegranite pakushanda zvakanaka.

Pakupedzisira, gakava rekuti "Granite vs. Cast Iron" harisi rekuti ndechipi chinhu chiri nani, asi kuti ndechipi chiri nani kuneiweGranite inopa kugadzikana, kururama, uye nyore kugadzirisa, zvichiita kuti ive shasha isingapokane yerabhoritari yemazuva ano inodzorwa nemamiriro ekunze. Simbi yakakandwa inopa kusimba, kushanduka-shanduka, uye kushanda zvakanaka kwemari, ichichengetedza nzvimbo yayo semusana wakasimba wekuongorora kwemaindasitiri. Nekunyatsoongorora mamiriro ako ezvakatipoteredza, mhando yezvikamu zvaunoongorora, uye kugona kwako kuchengetedza kwenguva refu, unogona kusarudza plate yepamusoro ichashanda sehwaro hwakavimbika hwechirongwa chako chekusimbisa hunhu. Kunyangwe ukasarudza kusimba kwechisikigo kwedombo kana kusimba kwesimbi, chinhu chikuru chiri mukunzwisisa fizikisi iri shure kwezvinhu uye kuremekedza zvisingakwanisike.
