Kemgbe 1980s, njirimara pụtara ìhè nke mmepe nke ụlọ ọrụ carbide cimented n'ụwa bụ ndị a: n'otu aka ahụ, carbide cemented a na-ekpuchi etolitela ngwa ngwa, mmepụta ya na-abawanye nke ukwuu, na mpaghara ngwa ya na-aga n'ihu na-agbasawanye, na E tinyewo ya nke ọma na usoro nhazi dị arọ dị ka ịcha.

Site na mmepe ngwa ngwa nke ụlọ ọrụ eletrọnịkị na ụlọ ọrụ nhazi igwe, carbide cimented ultra-fine etolitela ngwa ngwa na 1980, yana mmụba na-aga n'ihu nke ịdị mma yana mgbasawanye nke mmepụta.

Njirimara ọzọ nke mmepe nke ụlọ ọrụ carbide cimented na ụwa na 1980 bụ na ngwaahịa carbide cimented na-etolite n'ụzọ ziri ezi na miniaturization.
