Kodi ndi zokutira zingati pamwamba pa HSS drill bit? Ndipo ndi iti yabwino kuposa iyi?

Mabowole achitsulo chothamanga kwambiri (HSS) nthawi zambiri amakhala ndi zokutira zosiyanasiyana pamwamba zomwe zimapangidwa kuti ziwongolere magwiridwe antchito awo komanso kulimba kwawo. Zophimba zapamwamba kwambiri za mabowole achitsulo chothamanga kwambiri ndi izi:

1. Chophimba cha Oxide Chakuda: Chophimba ichi chimapereka mphamvu yolimbana ndi dzimbiri ndipo chimathandiza kuchepetsa kukangana panthawi yobowola. Chimathandizanso kusunga mafuta pamwamba pa chobowola. Zidutswa za pulasitiki zophimbidwa ndi oxide wakuda ndizoyenera kubowola zinthu monga matabwa, pulasitiki ndi chitsulo.

2. Chophimba cha Titanium Nitride (TiN): Chophimba cha TiN chimawonjezera kukana kuwonongeka ndipo chimathandiza kuchepetsa kukangana, motero chimawonjezera nthawi ya zida ndikuwonjezera magwiridwe antchito pakubowola kotentha kwambiri. Zidutswa zobowola za TiN ndizoyenera kubowola zinthu zolimba monga chitsulo chosapanga dzimbiri, chitsulo chosungunuka, ndi titaniyamu.

3. Chophimba cha Titanium carbonitride (TiCN): Poyerekeza ndi chophimba cha TiN, chophimba cha TiCN chili ndi mphamvu yolimba komanso yolimba. Ndi choyenera kugwiritsa ntchito zinthu zobowola ndi zinthu zotentha kwambiri kuti chikhale ndi moyo wautali komanso magwiridwe antchito a zida pobowola zinthu zovuta.

4. Chophimba cha Titanium aluminiyamu nitride (TiAlN): Chophimba cha TiAlN chili ndi mphamvu yolimba komanso yolimba pakati pa zophimba zomwe zili pamwambapa. Ndi choyenera kuboola zitsulo zolimba, zitsulo zotentha kwambiri ndi zipangizo zina zovuta kuti ziwonjezere nthawi ya zida ndikuwonjezera magwiridwe antchito m'mikhalidwe yovuta yoboola.

Chophimba chomwe chili bwino chimadalira momwe kubowolera ndi zinthu zomwe zikubowoledwa. Chophimba chilichonse chili ndi ubwino wapadera ndipo chapangidwira mitundu yosiyanasiyana ya zipangizo ndi mikhalidwe yobowolera. Pa kubowolera zinthu zodziwika bwino, chobowolera chakuda chokhala ndi oxide chingakhale chokwanira. Komabe, pa ntchito zovuta kwambiri zokhudzana ndi zipangizo zolimba kapena zotentha kwambiri,Zidutswa zobowola zophimbidwa ndi TiN, TiCN kapena TiAlN zitha kukhala zoyenera kwambiri chifukwa cha kuwonongeka kwawo komanso kukana kutentha.
