Indlela Yokuguqula Phakathi Kwemiluko Ye-intshi Ehlanganisiwe

Intambo iyisakhiwo esivunguzayo esisetshenziselwa ukuxhuma amabhawodi namantongomane. Emazweni nasezifundeni ezahlukene, kusetshenziswa amazinga ahlukene entambo. I-Imperial kanye ne-metric yizindinganiso ezimbili ezivame kakhulu.
Ngokwezinga laseBrithani, Imininingwane yochungechunge olujwayelekile yi-UNC ne-UNF. I-UNC isifinyezo se-Unified National Coarse, okubhekise kuchungechunge oluhlangene lwezwe olumahhadla; I-UNF isifinyezo se-Unified National Fine, okubhekiselwa kuchungechunge lwenhlawulo lukazwelonke oluhlanganisiwe. Ngokwesibonelo, I-UNC 1/4-20 kusho umucu kazwelonke omahhadla ohlangene onephimbo elithi 20 I-TPI (imicu iyintshi ngayinye) kanye nobubanzi be 1/4 intshi.

Imicu ehlanganisiwe yesistimu eyi-intshi isetshenziswa kakhulu emazweni esistimu eyi-intshi. Lolu hlobo lwentambo luhlukaniswe ngochungechunge oluthathu: uchungechunge lochungechunge lwama-UNC, uchungechunge oluhle lwe-UNF, uchungechunge lochungechunge oluhle lwe-UNFF, kanye nochungechunge lwephimbo olungaguquki lwe-UN.

Indlela yokumaka: Idayamitha yochungechunge-inombolo yemicu iyintshi ngayinye; Izinga lokunemba kwekhodi yochungechunge

Isibonelo: Uchungechunge lwamazinyo amaholo 3/8-16 I-UNC-2A

Fine tooth series 3/8-24 UNF-2A

Uchungechunge lwamazinyo amahle kakhulu 3/8-32 UNFF-2A

Uchungechunge lwephimbo elilungisiwe 3/8—20 UN—2A

Idijithi yokuqala 3/8 imelela ububanzi obungaphandle bomucu ngamasentimitha. Ukuze uguqulele kuyunithi ye-metric mm, phindaphinda nge 25.4, leyo, 3/8×25.4=9.525mm; inombolo yesibili neyesithathu 16, 24, 32, na- 20 kukhona Inombolo yamazinyo iyintshi ngayinye (inani lamazinyo ngobude obungama-25.4mm); amakhodi ombhalo ngemva kwedijithi yesithathu, I-UNC, UNF, UNFF, KANYE, amakhodi ochungechunge, kanye namadijithi amabili okugcina, 2A, izinga lokunemba.

Kubalulwe esilinganisweni sochungechunge oluhlanganisiwe ukuthi usayizi wegama ungaba namaphimbo ahlukene. Ngokwesibonelo, 1/2 unayo 13 amazinyo, 16 amazinyo, 20 amazinyo, na- 32 amazinyo. Izinga liyakubeka lokho 13 amazinyo angamazinyo amaholo futhi 20 amazinyo angamazinyo amahle. 28 amazinyo angamazinyo amahle kakhulu; 16 amazinyo kanye 32 amazinyo womabili abizwa ngokuthi iphimbo eliqhubekayo, okungahlukile emazinyweni amaholoholo namazinyo amahle.
