Kwerekana ibicuruzwa
Imiyoboro ya Counter ifite inkingi ikarishye kumpera yimpera yazo, mugihe imyironge yizunguruka ifite inguni ya bevel, ikunze kwitwa inguni ya rake, kumutwe.Kugirango habeho gushira hamwe no kuyobora neza iyi myitozo, izanye nu mwanya wo kuyobora uhuza neza nu mwobo uriho usanzwe uri mu kazi kugirango habeho gushira hamwe no kuyobora.Nkigisubizo cyuruzitiro rwa silindrike hamwe numutwe wapanze hamwe nu mwobo ucuramye, gufunga byoroshye.Impanuro yafashwe ifite ibikoresho byometseho, bikwiriye gukata.Binyuze mu mwobo, ibyuma byicyuma birashobora kuzunguruka no gusohora hejuru bitewe nu mwobo usohora.Imbaraga za Centrifugal zirashobora gufasha cyane mugukuraho ibyuma byuma hejuru yumurimo wakazi, kugirango bitazashushanya hejuru kandi bikagira ingaruka mbi kumiterere yakazi.Hano hari ubwoko bubiri bwubuyobozi bwanditse, kandi umwobo wa Countersunk urashobora no gukorwa mugice kimwe nibiba ngombwa.
Imyitozo ya Countersink ikoreshwa kumirimo itandukanye harimo kubara no gutunganya ibyobo byoroshye.Igishushanyo cyihariye n'imiterere yabo byorohereza uyikoresha gukora neza no kuzamura ubwiza bwibicuruzwa byarangiye.
