Din335 HSS Countersink Drill Bit
Bandhiga Alaabta
Qaybta ugu weyn ee goynta countersink cylindrical waa cidhifka goynta dhamaadka, halka xagasha goynta ee biibiile wareeg ah loo arko xagasha rake.Cidhifka layligani waxa uu leeyahay biro hage oo si adag ugu habboon daloolka jira ee qaybta shaqada si loo hubiyo udub dhexaadka iyo hanuuninta wanaagsan.Qalabka gacanta waxaa loogu talagalay inuu noqdo cylindrical, kaas oo ku habboon xajinta.Qaybta madaxa gooyuhu waa duuban tahay waxayna leedahay dalool qardajeex ah oo dhex socda.Cidhifka jeexan ee caarada duuban ayaa leh gees goyn oo loo isticmaali karo goynta.Godka dhex mara waxa uu u adeegaa sidii dalool dheecaan ah oo jajab ah, iyo jajabyada birta ah waa la rogman doonaa oo kor baa loo soo dayn doonaa.Xoogaga centrifugal ayaa kaa caawin doona inaad xoqdo jajabyada birta ee dusha sare ee shaqada si looga fogaado xoqidda dusha sare ee shaqada oo saameyn ku yeelata tayada.Boosta hagaha noocaan ah waa la go'i karaa, boostada hagaha iyo miiska miiska ayaa sidoo kale laga dhigi karaa hal gabal.
Guud ahaan, daloolinta countersink waa qalab si gaar ah loo isticmaalo in lagu farsameeyo godadka siman iyo saxanka.Qaab-dhismeedkeeda iyo naqshadaynteeda waxay gacan ka geystaan hagaajinta hufnaanta shaqada iyo habaynta tayada.
