Mafotokozedwe Okhazikika a Zopangira

Miyezo yomwe imagwiritsidwa ntchito kwambiri ndi iyi:
GB-China National Standard (National Standard)
ANSI-American National Standard (American Standard)
DIN-German National Standard (German Standard)
ASME-American Society of Mechanical Engineers Standard
JIS-Japanese National Standard (Japanese Standard)
BSW-British National Standard

Kuphatikiza pa miyeso yoyambira, monga makulidwe a mutu ndi mutu wotsutsana, gawo losiyana kwambiri la miyezo yotchulidwa ya zomangira ndi ulusi.Ulusi wa GB, DIN, JIS, ndi zina zonse zili mu MM (mamilimita) , pamodzi amatchedwa metric threads.Ulusi ngati ANSI, ASME, uli mainchesi ndipo umatchedwa American standard threads.Kupatula ulusi wa metric ndi ulusi waku America, palinso muyezo wa BSW-British, ndipo ulusiwo ulinso mainchesi, omwe amadziwika kuti ulusi wa Whitworth.

Ulusi wa metric uli mu MM (mm), ndipo mbali yake ya cusp ndi madigiri 60.Ulusi wa America ndi Imperial umayesedwa mu mainchesi.Mbali ya cusp ya ulusi waku America ndi madigiri 60, pomwe mbali ya cusp ya ulusi waku Britain ndi madigiri 55.Chifukwa cha mayunitsi osiyanasiyana oyezera, njira zoyimira ulusi wosiyanasiyana zimasiyananso.Mwachitsanzo, M16-2X60 imayimira ulusi wa metric.Zikutanthauza kuti m'mimba mwake mwadzina la wononga ndi 16MM, phula ndi 2MM, ndipo kutalika kwake ndi 60MM.Chitsanzo china: 1/4-20X3/4 amatanthauza ulusi wa dongosolo la Britain.tanthauzo lake lenileni ndi m'mimba mwake mwadzina wa wononga ndi 1/4 inchi (inchi imodzi = 25.4MM), pali mano 20 pa inchi imodzi, ndi kutalika ndi 3/4 inchi.Kuphatikiza apo, ngati mukufuna kuwonetsa zomangira zopangidwa ku America, UNC ndi UNF nthawi zambiri zimawonjezedwa pambuyo pa zomangira zopangidwa ndi Britain kuti zisiyanitse ulusi wopangidwa ndi America ndi ulusi wabwino wopangidwa ku America.

Yihe enterprise ndi kampani yomwe imagwira ntchito bwino popanga zomangira za amchine zopangidwa ndi US ANSI, BS makina screw, bawuti malata, indlcuidng 2BA, 3BA, 4BA;Zomangira makina opangidwa ndi Germany DIN (DIN84/ DIN963/ DIN7985/ DIN966/ DIN964/ DIN967);GB Series ndi mitundu ina yazinthu zokhazikika komanso zosakhazikika monga zomangira zamakina ndi mitundu yonse ya zomangira zamakina amkuwa.
