Kambiranani za HSS ndi Carbide drill bits

Monga zidutswa ziwiri zobowola zomwe zimagwiritsidwa ntchito kwambiri zopangidwa ndi zipangizo zosiyanasiyana, zidutswa zobowola zachitsulo chothamanga kwambiri ndi Zinthu zobowolera za carbide, makhalidwe awo ndi ati, ubwino ndi kuipa kwawo ndi kotani, komanso kuti ndi chinthu chiti chomwe chili bwino poyerekeza ndi china chilichonse.

Chifukwa chomwe ma drill bit achitsulo chothamanga kwambiri amagwiritsidwa ntchito kwambiri ndichakuti chitsulo chothamanga kwambiri chimakhala ndi mphamvu yolimbana ndi kutentha kwambiri komanso kutopa, ndipo sichidzapanga kusintha ndi kuwonongeka panthawi yodula kutentha kwambiri. Zachidziwikire, zimatsimikiziridwa pang'onopang'ono ndi nthawi yomwe ikugwiritsidwa ntchito. Padzakhala kutayika, koma zinthu zomwe zimachitika nthawi yomweyo popanda kuwononga nthawi ndizofunika kwambiri. Kachiwiri, kulimba kwa ma drill achitsulo chothamanga kwambiri ndi kwakukulu kwambiri kuposa kwa zipangizo zina. Ma drill bit sayenera kungosunga kukhazikika ndi kulimba kokha. Komanso ndi okwera kwambiri. Popanda kulimba bwino, drill bit imakonda kusweka, zomwe zimapangitsa kuti m'mimba mwake pakhale dzenje losakhazikika pamene drill bit yatha.

Ubwino waukulu wa ma carbide drill ndi kuuma kwawo kwakukulu. Ubwino wa kuuma kwakukulu umalola ma carbide drill kukumana ndi zitsulo zina zambiri zolimba kwambiri. Komabe, vuto lalikulu la ma carbide drill ndi kuuma kochepa, komwe kumakhala kofooka kwambiri komanso kosavuta kudula. Pankhani ya mabowo akuya, ngati palibe njira yapadera monga chobowolera cha carbide drill bit chothandizira sichili ndi zotsatira za chobowolera chachitsulo chothamanga kwambiri, ndithudi, kuuma kwa chobowolera chachitsulo chothamanga kwambiri kumatha kupirira.

Kawirikawiri, zitsulo zobowola zothamanga kwambiri ndi zitsulo zobowola za carbide zili ndi makhalidwe omwewo, koma mfundo yabwino kwambiri ya chitsulo chothamanga kwambiri ili mu kulimba kwabwino, pomwe mfundo yabwino kwambiri ya zitsulo zobowola za carbide ndi kuuma kwakukulu, ndipo kusiyana kwa zoyipa zake ndikuti kuuma kwa zitsulo zobowola zothamanga kwambiri sikukwanira, ndipo chitsulo cholimba kwambiri chimakonzedwa.

Sizimatha kutha, ndipo kulimba kwa ma drill a carbide pokonza mabowo akuya sikwabwino, kotero posankha drill, muyenera kusankha drill yogwirizana nayo malinga ndi momwe zinthu zilili. Mwachitsanzo, ma drill achitsulo othamanga kwambiri opangidwa ndi mkuwa, chitsulo ndi aluminiyamu ndi oyenera kuposa ma drill a carbide. DTH high-hardness carbide drill bit idzakhala yolimba kuposa drill yachitsulo yothamanga kwambiri.
