Mefuta ea likotoana tsa ho cheka tse ka sebelisoangMochini oa CNC oa ho cheka le oa ho silakenyeletsa twist drill, U drill, li-drill tse mabifi, le li-core drill.
Li-twist drill li sebelisoa haholo mochineng oa khatiso oa hlooho e le 'ngoe ho cheka liphanele tse bonolo. Hona joale ha li fumanehe hangata ho baetsi ba liboto tse kholo tsa potoloho, 'me botebo ba bona ba ho phunya bo ka fihla ka makhetlo a 10 bophara ba drill.
Ha substrate stack e sa phahame, tšebeliso ea matsoho a drill e ka qoba ho kheloha ho cheka. TheMochini oa ho cheka oa CNCe sebelisa sekontiri se entsoeng ka samente sa carbide se tsitsitseng, se khetholloang ke bokhoni ba ho fetola mochini oa ho phunya. Ho nepahala ha boemo bo phahameng, ha ho hlokahale ho sebelisa matsoho a drill. Leqhubu le leholo la helix, lebelo la ho tlosa chip ka potlako, le loketseng ho itšeha ka lebelo le phahameng. Ka har'a bolelele bo felletseng ba lekolilo la chip, bophara ba boro ke khoune e sothehileng, 'me khohlano e nang le lebota la lesoba nakong ea ho cheka e nyane, mme boleng ba ho phunya bo holimo. Li-diameter tse tloaelehileng tsa shank ke 3.00mm le 3.175mm.
Karolo ea ho cheka bakeng sa ho cheka lakane ea li-tube hangata e sebelisa carbide e entsoeng ka samente, hobane lesela la khalase ea epoxy le koahetsoeng ka poleiti ea koporo e roala sesebelisoa kapele haholo. Seo ho thoeng ke samente carbide e entsoe ka tungsten carbide phofo e le matrix le cobalt phofo e le setlamo ka khatello le sintering. Hangata e na le 94% tungsten carbide le 6% cobalt. Ka lebaka la boima ba eona bo phahameng, e sebetsa haholo, e na le matla a itseng, 'me e loketse ho itšeha ka lebelo le phahameng.
Mafutsana a thata le a brittle haholo. E le ho ntlafatsa ts'ebetso ea carbide e entsoeng ka samente, ba bang ba sebelisa lera la 5-7 microns ea titanium carbide e thata (TIC) kapa titanium nitride (TIN) karolong ea carbide ka ho kenngoa ha mouoane oa lik'hemik'hale ho etsa hore e be le boima bo Holimo. Ba bang ba sebelisa theknoloji ea ho kenya ion ho kenya titanium, naetrojene le k'habone ka har'a matrix ho ea botebong bo itseng, e leng se sa ntlafatseng feela ho thatafala le matla, empa le likaroloana tsena tse kentsoeng li ka falla ka hare ha karolo ea boro e khutlela fatše. Ba bang ba sebelisa mekhoa ea 'mele ho etsa lera la filimi ea daemane ka holimo hocheka hanyane, e leng ho ntlafatsang haholo ho thatafala le ho apara ho hanyetsa ha sekhahla sa ho phunya. Boima le matla a carbide e entsoeng ka samente ha e amane feela le karo-karolelano ea tungsten carbide le cobalt, empa hape le likaroloana tsa phofo.
Bakeng sa likaroloana tsa li-drill tse entsoeng ka samente, boholo bo tloaelehileng ba lithollo tsa tungsten carbide phase bo ka tlase ho 1 micron. Mofuta ona oa ho cheka ha o na boima bo phahameng feela empa o boetse o ntlafatsa matla a ho hatella le a flexural. E le ho boloka litšenyehelo, lisebelisoa tse ngata tsa ho cheka hona joale li sebelisa sebopeho sa shank se cheselitsoeng. Karolo ea pele ea ho phunya e entsoe ka alloy e thata ka kakaretso. Hona joale shank e ka morao ea drill e entsoe ka tšepe e sa hloekang, e fokotsang litšenyehelo haholo. Leha ho le joalo, ka lebaka la tšebeliso ea lisebelisoa tse fapaneng, concentricity e matla ha e ntle joaloka e thata ka kakaretso. Alloy drill bits, haholo-holo bakeng sa li-diameter tse nyane.
