yintoni umahluko phakathi kwentonga ephothiweyo yemetric kunye ne-Bhritane kunye ne-American thread stick?

I-Metric thread rodkwayeintonga yaseBritani yaseMelikayimigangatho emibini yokwenziwa kwemisonto eyahlukeneyo. Umahluko phakathi kwabo ubonakaliswa ikakhulu kwindlela yokumelwa kobungakanani, inani leentambo, i-bevel angle kunye nobubanzi bokusetyenziswa. Kwimveliso yoomatshini, kuyafuneka ukuba ukhethe umgangatho ofanelekileyo womsonto ngokwemeko ethile.

1. Ngowuphi owona mahluko mkhulu phakathi kwe-metric stud bolt kunye neBhritane ne-American stud bolt?

Ibholithi ye-Metric studyathandwa eFransi, kwaye iimpawu zayo kukuba isebenzisa iimilimitha njengeeyunithi, ineentambo ezimbalwa, kwaye ine-engile ye-bevel ye-60 degrees. IIbholithi yaseBritani neyaseMelikayavela e-United Kingdom nase-United States, kwaye iimpawu zayo kukuba isebenzisa i-intshi njengeeyunithi, ineentambo ezininzi, kwaye ine-engile ye-bevel ye-55 degrees.

2. Uthini umahluko phakathi kwe metric threaded rod din975 kunye ne British and American threaded rod din975 ubukhulu bentambo?

Ngokumalunga nobukhulu, ubungakanani bemisonto ye-metric yentonga ye-din975 ichazwa ngokwemiqathango yobubanzi (mm) kunye ne-pitch (mm), ngelixa i-British kunye ne-American threads rod i-din975 ibonakaliswe ngokobukhulu (intshi), i-pitch, kunye neprogram yentambo ( inani lemisonto).

Umzekelo, i-M8 x 1.25 intambo, apho “M8″ imele i-diameter ye-8 mm, kwaye “1.25″ imele umgama we-1.25 mm phakathi komsonto ngamnye. Kwimisonto yaseBrithani neyaseMelika, i-1/4 -20 i-UNC imele ubungakanani bentambo ye-1/4 intshi, i-pitch ye-20 ye-intshi nganye, kwaye i-UNC imele umgangatho wesizwe we-coarse-grain for thread.

3. Umda wokusetyenziswa kwemetric threaded rod umenzi wentonga waseBhritani nowaseMelika

Kuba umenzi wentonga owenziwe ngemetric unemisonto embalwa kunye neebevels ezincinci, akukho lula ukulumana ngesantya esiphezulu, ngoko uninzi lwamalungu oomatshini asebenzisa imisonto yemetric. Iintambo zaseBritani nezaseMelika zihlala zisetyenziswa kwezinye izihlandlo ezikhethekileyo, njengemisonto yepibho eqhelekileyo yaseMelika.

4. Ukuguqulwa kwenkcazo

Kuba imisonto yemetric kunye nemisonto yaseBritane neyaseMelika iyimigangatho emibini eyahlukeneyo yokuvelisa, ukuguqulwa kuyafuneka. Iindlela zokuguqula eziqhelekileyo ziquka ukusebenzisa izixhobo zokuguqula okanye ukubhekisela kwiitafile zokuguqula.
