Ityhubhu yesikwereluhlobo lwezixhobo ezisetyenziswa kakhulu kushishino lokwakha kwimizi-mveliso, ezifunwa kakhulu. Kukho iimveliso ezininzi zetyhubhu yesikwere ezithengiswayo, kwaye umgangatho awulingani. Ingqwalasela kufuneka inikwe kwindlela yokukhetha xa ukhetha:
1. Jonga ubungakanani
Isixhobo sokulinganisa i-vernier clamp singasetyenziselwa ukulinganisa nje ukuba ubungakanani bokwenyani bumalunga nengcaciso enye okanye buncinci kunobungakanani obuphawulweyo. Ngokubanzi, akukho mahluko mkhulu phakathi kweetyhubhu zesikwere ezilungileyo; Ukongeza, kufuneka kuqatshelwe ukuba eminye imibhobho yesikwere ekumgangatho ophantsi iya kukhohlisa umbono wabantu ngokuqhekeza umlomo. Ke ngoko, ubuso bomphezulu wombhobho wentsimbi kufuneka bube yi-oval ethe tyaba, ngelixa ubuso bomphezulu wezinto eziqhelekileyo kufuneka bube yisangqa.
2. Jonga ukusebenza
Ityhubhu yesikwere ineempawu ezithile zokutsala kunye nokucinezela, ngoko ke singaziqwalasela ezi nkalo xa sikhetha ityhubhu yesikwere: amandla okutsala kukusebenza kweityhubhu yesikwereisiseko, kwaye okukhona amandla okutsalwa aphezulu kuthetha ukuba ukusebenza kwetyhubhu yesikwere kuya kuba ngcono; Kufuneka kuqwalaselwe ngokubanzi ukumelana nokucinezelwa kunye nokumelana nokugoba.
3. Jonga umgangatho womphezulu
Umgangatho womphezulu we-inferioriityhubhu zesikwereayilunganga ngenxa yokuqengqeleka kwezinto ezingavuthwanga, kwaye zihlala zineziphene ezifana nokurhawuzelelwa kwaye zinomvakalelo orhabaxa ngokubanzi. Ezinye iifektri ezincinci zentsimbi zinombala obomvu womphezulu ngenxa yobushushu obunganeleyo bokufudumeza kunye nesantya sokuqengqeleka; Umgangatho wetyhubhu yesikwere esemgangathweni ophezulu uyafaneleka, ngaphandle kweziphene ezicacileyo, kwaye umbala umhlophe kwaye uqaqambile.
4. Jonga iphakheji
Uninzi lweepayipi eziqhelekileyo ezizikwere ezizinxantathu zipakishwa kwiinqwaba ezinkulu xa zithunyelwa ezivela kumzi-mveliso. Iipleyiti zesinyithi ezihambelana nezinto zokwenyani zixhonywa kwiinqwaba zentsimbi, zibonisa umenzi, uphawu lwentsimbi, inombolo yebhetshi, iinkcukacha kunye nekhowudi yokuhlolwa, njl.njl.; Ingqwalasela ekhethekileyo kufuneka inikwe iimveliso zeetyhubhu ezizinxantathu ezineenqwaba ezincinci (malunga neenqwaba ezilishumi) okanye ngobuninzi, ezingenazo iilebheli zesinyithi kunye nezatifikethi zokuqinisekisa umgangatho.
