Olee otú iji a micrometer tụọ obere akụkụ

Micrometer - nwere nnọọ elu nkenke ngwaọrụ odomo size nke akụkụ. Ọ na-eji ebe mkpa ka scrupulous ememe nke akụkụ ke imewe nke ngwaahịa. Ya n'ihe ziri ezi nke otu puku nke a millimeter (micrometer ma ọ bụ micron), na njehie bụ naanị 2 50 microns. Ọ dị nnọọ ihe ezi karịa na otu caliper.

Isi akụkụ nke micrometer bụ a mwekota. Ọ na-mere anyịnya na mmasị thereto niile n'akụkụ ndị ọzọ nke ngwaọrụ: ikiri ụkwụ (na-eje ozi dị ka a ofu abutment mgbe n'ịrụ nha), azuokokoosisi, a micrometer ịghasa, na drum na ratchet stopa. Azuokokoosisi, na nke na ọnụ ọgụgụ na-fixedly jikọọ na anwụrụ mgbodo. The ọnụ ọgụgụ ndị mejupụtara edebe tinyere azuokokoosisi perpendicular ka ihe ize ndụ na ọrịa strok. N'okpuru ize ndụ ọrịa strok etinyere nsannsan 1 mm na Valium - 0,5 mm. Naa i nwere ike ịhụ ihe electronic micrometer, ebe niile ụkpụrụ na-egosipụta.
