Kayan abu
1. Karfe Mai Sauri (HSS):
Ƙarfe Mai Girma (HSS) ya kasance mai mahimmanci a cikin kayan aikin yankan fiye da karni, wanda aka kimanta don aikace-aikacensa mai yawa da kuma iyawa.HSS drill bits an san su da juzu'in su, suna aiki da kyau tare da aikin atisayen hannu biyu da tsayayyun dandamali kamar na'urorin rawar soja.Babban fa'idar HSS shine iyawar sa na sake kaifi, yana haɓaka daɗewar fa'ida da sanya shi zaɓi mai tsada don kayan aikin lathe shima.Bugu da ƙari, HSS yana da maki daban-daban, kowannensu yana da ƙayyadaddun abubuwa daban-daban don biyan takamaiman buƙatun yanke.Wannan nau'in nau'in nau'in karfe yana ƙara haɓakawa na HSS, yana mai da shi wani abu mai mahimmanci kuma mai mahimmanci a cikin ayyuka daban-daban na inji.
2. Cobalt HSS (HSSE ko HSSCO):
Idan aka kwatanta da HSS na gargajiya, Cobalt HSS yana nuna ƙwaƙƙwaran ƙarfi da juriyar zafi.Wannan haɓakawa a cikin kaddarorin yana haifar da ingantaccen ingantaccen juriya, yana sa HSSE rawar soja ya fi ɗorewa da inganci.Haɗin cobalt a cikin HSSE ba wai kawai yana ba da gudummawa ga ƙara ƙarfin juriya ba amma yana haɓaka tsawon rayuwarsa gaba ɗaya.Kamar daidaitaccen HSS, HSSE ragowa suna riƙe fa'idar kasancewa mai kaifi, wanda ke ƙara haɓaka rayuwarsu mai amfani.Kasancewar cobalt a cikin HSSE yana sa waɗannan raƙuman ruwa sun dace musamman don ƙarin ayyuka na hakowa inda tsayin daka da juriya ke da mahimmanci.
3. Carbide:

Ita ce mafi yawan launi ga ɗigon motsa jiki na HSS.Mafi dacewa don kayan laushi irin su aluminum gami da ƙananan ƙarfe na carbon, kayan aikin da ba a rufe su ba ne mafi araha.
2. Rufin Bakin Oxide:
Yana ba da mafi kyawun lubrication da juriya mai zafi fiye da kayan aikin da ba a rufe su ba, inganta rayuwar rayuwa ta sama da 50%.
3. Titanium Nitride (TiN) Rufi:
Abubuwan rawar soja masu rufaffiyar Titanium suna yin kyau sosai a yanayin aikace-aikacen da yawa saboda halayen aikinsu na musamman.Na farko, Yana haɓaka ƙarfin ƙarfi da juriya na abrasion ta hanyar sutura, ƙyale bit ya kasance mai kaifi yayin hakowa ta kayan aiki mai ƙarfi, da kuma samar da rayuwar sabis mai tsayi.Waɗannan raƙuman raƙuman raƙuman raƙuman ruwa suna rage juzu'i da haɓaka zafi, haɓaka haɓakar yankewa yayin da suke kare ɗan ƙaramin zafi.Titanium-plated bits sun dace don amfani da su a cikin abubuwa da yawa, irin su bakin karfe, aluminum da itace, yana sa su dace don aikin injiniya da aikace-aikacen gida.Bugu da ƙari, waɗannan raƙuman ruwa suna shiga cikin kayan cikin sauri da tsabta, suna samar da wuri mafi kyau.Duk da yake titanium-plated drills iya kudin fiye da na yau da kullum drills, da high yadda ya dace da kuma tsawon rai sa su mai kyau koma kan zuba jari ga aikace-aikace da bukatar high abrasion juriya da daidai yanke.
4. Aluminum Titanium Nitride (AlTiN) Rufin:
Na farko, rufin AlTiN yana da juriya mai zafi sosai, yana ba su damar yin fice a cikin yankan saurin sauri da kuma sarrafa kayan gami masu zafi.Abu na biyu, wannan shafi yana inganta juriya na abrasion kuma yana haɓaka rayuwar kayan aiki, musamman lokacin yin amfani da kayan aiki mai ƙarfi kamar bakin karfe, gami da titanium gami da gami na tushen nickel.Bugu da kari, da AlTiN shafi rage gogayya tsakanin rawar soja bit da workpiece, inganta machining yadda ya dace da kuma taimakawa wajen cimma wani smoother yankan surface.Hakanan yana da kyakkyawan juriya na iskar shaka da kwanciyar hankali na sinadarai, yana ba shi damar kula da aiki a cikin matsanancin yanayin aiki.Gabaɗaya, ƙwanƙwasa mai rufaffiyar AlTiN ya dace don aikace-aikacen injina mai sauri, daidaitaccen mashin, kuma sun dace musamman don sarrafa kayan aiki masu wuya waɗanda ke haifar da ƙalubale ga ƙwanƙwasa na al'ada.
