Ọmụma nke Roughness

1, Mgbe nhazi, akụkụ nwere ike na-enweta nnukwu ma ọ bụ obere ọnụ na ndagwurugwu n'elu workpiece n'ihi ọnwụ ngwaọrụ, mgbawa nkwụnye ego, na burrs. Ogo elu ugwu na ndagwurugwu ndị a pere mpe, a na-ahụkarị naanị mgbe ebuliri ya elu. A na-akpọ njirimara micro geometric a dị nro n'elu.
2. Mmetụta nke elu Roughness na Performance nke Mechanical Parts
Ịdị nro dị n'elu nwere mmetụta dị ịrịba ama na ịdịmma nke akụkụ, tumadi na-elekwasị anya na nguzogide iyi ha, ihe ndị dabara adaba, ike ike ọgwụgwụ, izi ezi workpiece, na nguzogide corrosion.
① Mmetụta na esemokwu na iyi. Mmetụta nke nhụsianya elu na akụkụ uwe na-apụtakarị na ọnụ ọgụgụ kasị elu na ọnụ ọgụgụ kasị elu, ebe akụkụ abụọ na-abanye na ibe ha, nke bụ n'ezie kọntaktị kacha elu. Nrụgide dị na ebe kọntaktị dị oke elu, nke nwere ike ime ka ihe ahụ na-abanye na mmiri plastik. Ka elu na-esiwanye ike, otú ahụ ka ọ na-eme ka ọ dịkwuo njọ.
② Mmetụta na njirimara nhazi. Enwere ụdị ihe abụọ dabara adaba, nnyonye anya dabara na mkpochapụ. Maka nnyonye anya dabara adaba, n'ihi nkwụsị nke elu elu n'oge mgbakọ, a na-ebelata ihe ntinye aka, nke na-ebelata ike njikọ nke ihe ndị ahụ; Maka nkwụsị nke ọma, ka ọnụ ọgụgụ kasị elu na-aga n'ihu na-agbadata, ogo nkwụsị ga-abawanye. Ya mere, nhụsianya elu na-emetụta nkwụsi ike nke ihe ndị na-emekọ ihe.
③ Mmetụta nke iguzogide ike ike ọgwụgwụ. Ka elu akụkụ ahụ na-esiwanye ike, ka ọnyà ahụ dị omimi, na obere radius curvature nke ebe a na-adọba ụgbọala, na-eme ka ọ dịkwuo mfe itinye uche na nrụgide. Ya mere, ka akụkụ ahụ dị n'elu ya na-abawanye, otú ahụ ka mgbakasị ahụ na-adịwanye njọ, na-ebelata ike ọgwụgwụ ya.
④ Mmetụta corrosive. Ka nnukwu ihe dị n'elu nke akụkụ ahụ, nke dị omimi nke ndagwurugwu ebili mmiri ya. N'ụzọ dị otú a, ájá, mmanụ lubricating mebiri emebi, acidic na alkaline corrosive bekee nwere ike ịgbakọ ngwa ngwa na ndagwurugwu ndị a ma banye n'ime oyi akwa nke ihe ahụ, na-eme ka mmebi nke akụkụ ahụ dịkwuo njọ. Ya mere, ibelata nhụsianya elu nwere ike ịkwalite nguzogide corrosion nke akụkụ.
