Zingaphi zogqume umphezulu ze HSS drill bit?kwaye yeyiphi engcono?

Iintsimbi ze-speed-speed steel (HSS) zokubhola zihlala zineengubo ezahlukeneyo zomphezulu ezenzelwe ukuphucula ukusebenza kwazo kunye nokuqina.Eyona nto ixhaphakileyo yokugquma umphezulu kwi-high-speed drill bits ibandakanya:

1. I-Black Oxide Coating: Le ngubo inika iqondo lokuxhathisa ukubola kwaye inceda ukunciphisa ukukhuhla ngexesha lokugaya.Ikwanceda ukugcina i-lubricant kwi-drill surface.Amasuntswana edrili afakwe i-oksidi emnyama alungele ukugrumba injongo ngokubanzi kwizinto ezinje ngomthi, iplastiki kunye nentsimbi.

2. I-Titanium Nitride (TiN) I-Coating: Ukugquma kwe-TiN kwandisa ukunganyangeki kwaye kunceda ukunciphisa ukukhuhlana, ngaloo ndlela ukwandisa ubomi besixhobo kunye nokuphucula ukusebenza kwizicelo zokuqhuba ukushisa okuphezulu.Amasuntswana okomba enziwe ngeTiN alungele ukugrumba izinto eziqinileyo ezifana nentsimbi engatyiwayo, intsimbi etyhidiweyo, kunye netitanium.

3. I-Titanium carbonitride (i-TiCN) yokugqoka: Xa kuthelekiswa ne-TiN yokugqoka, i-TiCN yokugqoka inokumelana nokugqoka okuphezulu kunye nokuchasana nokushisa.Ifanelekile ukubhobhoza i-abrasives kunye nezixhobo eziphezulu zokushisa ukuphucula ubomi besixhobo kunye nokusebenza kwizicelo ezifunwayo zokugaya.

4. I-Titanium aluminium nitride (TiAlN) yokugqoka: I-TiAlN yokugqoka inezinga eliphezulu lokumelana nokuxhatshazwa kunye nokuchasana nokushisa phakathi kwezi zixhobo ezingentla.Kufanelekile ukubhobhoza iintsimbi eziqinileyo, i-alloys ephezulu yokushisa kunye nezinye izinto ezicela umngeni ukwandisa ubomi besixhobo kunye nokuphucula ukusebenza kwiimeko ezinzima zokugaya.

Yiyiphi i-coating engcono kuxhomekeke kwisicelo esithile sokubhobhoza kunye nezinto ezichithwayo.Ingubo nganye inikezela ngeenzuzo ezizodwa kwaye yenzelwe iintlobo ezahlukeneyo zezixhobo kunye neemeko zokomba.Ngenjongo jikelele ukomba kwizinto eziqhelekileyo, i-drill drill bit emnyama inokwanela.Nangona kunjalo, kwizicelo ezifuna kakhulu ezibandakanya izinto ezinzima okanye ezinobushushu obuphezulu,I-TiN, i-TiCN okanye i-TiAlN i-drill bits inokufaneleka ngakumbi ngenxa yokuguga okuphuculweyo kunye nokumelana nobushushu.
