Lapho ukhetha imishini ye-carbide enosimende, izidingo zokunemba kwe-dimensional zokumba kufanele zicatshangelwe kuqala. Ngokuvamile, lapho imbobo incane okufanele icutshungulwe, kuncane ukubekezelelana. Ngakho-ke, abakhiqizi bemishini yokubhoboza ngokuvamile bahlukanisa izimbobo ngokuya ngobubanzi obujwayelekile bomgodi owenziwa ngomshini. Phakathi kwezinhlobo ezine ezingenhla zokumba i-carbide enosimende, imishini ye-carbide enosimende eqinile inokunemba okuphezulu komshini (ububanzi bokubekezelela φ10mm bokubhola be-carbide obuqinile bungu-0–0.03mm), ngakho-ke kuyisinqumo esingcono sokwenza izimbobo ezinemba kakhulu ;Ukubekezelela uhla lwemishini yokubhoboza i-carbide enosimende eshiselwe noma imiqhele ye-carbide engashintshwa ngosimende ingu-0～0.07mm, ofaneleka kakhulu ukucutshungulwa kwemigodi ngezidingo zokunemba okuvamile; ama-drill anezinkomba ze-carbide ezinosimende afaneleka kakhulu umshini onzima onzima Nakuba izindleko zawo zokucubungula ngokuvamile ziphansi kunezinye izinhlobo zokubhoboza, ukucubungula kwawo nakho kuphansi, nobubanzi bokubekezelela obungu-0～0.3mm (kuye ngokuthi ubude isilinganiso sobubanzi bokubhoboza), ngakho-ke ngokuvamile isetshenziselwa ukucutshungulwa kwembobo ngokunemba okuphansi, Noma ukuqedela ukuqedwa kwembobo ngokufaka indawo yensingo eyisicefe.
Ukuzinza kwe-drill bit ngokwayo kufanele futhi kucatshangelwe. Isibonelo, imishini ye-carbide eqinile iqinile, ngakho-ke ingakwazi ukufeza ukunemba okuphezulu kwemishini. I-drill bit ye-carbide eyinkomba efakwe usimende inokuqina kwesakhiwo futhi ijwayele ukuchezuka. Okufakwayo okunenkomba okubili kufakwe kule ngxenye yokubhoboza. Ukufakwa kwangaphakathi kusetshenziselwa umshini ingxenye emaphakathi yembobo, futhi okufakiwe kwangaphandle kusetshenziselwa umshini unqenqema lwangaphandle ukusuka kokufakwayo okungaphakathi kuya kububanzi obungaphandle. Njengoba i-blade yangaphakathi kuphela ingena ekusikeni esigabeni sokuqala sokucutshungulwa, i-drill bit isesimweni esingazinzile, esingabangela kalula ukuthi umzimba wokubhoboza uphambuke, futhi uma i-drill bit eside, inani elikhulu lokuphambuka. Ngakho-ke, lapho usebenzisa umshini wokubhoboza ofakwe usimende we-carbide enobude obungaphezu kuka-4D wokubhoboza, okuphakelayo kufanele kuncishiswe ngokufanele ekuqaleni kwesigaba sokumba, futhi izinga lokudla kufanele lenyuswe libe sezingeni elivamile ngemva kokungena ekusikeni okuzinzile. isigaba .
I-carbide drill bit eshiselwe kanye nokubhola komqhele we-carbide oshintshwayo owenziwe ngosimende wakhiwe ngamaphethelo amabili okusika alinganayo anohlobo oluzimele lwejiyomethri. Lo mklamo osezingeni eliphezulu wokusika wenza kungadingeki lapho usika ku-workpiece Yehlisa izinga lokuphakela, ngaphandle uma i-drill ifakwe ngokugobile futhi inqunywa nge-engeli ethile ebusweni bomsebenzi wokusebenza. Ngalesi sikhathi, kunconywa ukuthi unciphise izinga lokudla ngo-30% ukuya ku-50% lapho ubhoboza ngaphakathi nangaphandle. Ngenxa yokuthi insimbi yokubhoboza insimbi yalolu hlobo lwe-drill bit ingaveza ukuwohloka okuncane, ifaneleka kakhulu ukucutshungulwa kwe-lathe; kuyilapho i-hard carbide drill bit is brittle more, kulula ukuphuka uma isetshenziselwa ukucubungula i-lathe, ikakhulukazi uma i-drill bit ingagxili kahle. Lokhu kuyiqiniso ikakhulukazi ngezinye izikhathi.
Ukususwa kwe-chip kuyinkinga engenakuzitshwa lapho kubholwa. Eqinisweni, inkinga evame kakhulu okuhlangatshezwana nayo ekubhoboleni ukususwa kwe-chip okungalungile (ikakhulukazi lapho kwenziwa izingcezu zensimbi ezinekhabhoni ephansi), futhi le nkinga ayinakugwenywa kungakhathaliseki ukuthi hlobo luni lokubhola olusetshenziswayo. Ama-workshops okucubungula ngokuvamile asebenzisa umjovo wokupholisa wangaphandle ukusiza ukukhishwa kwe-chip, kodwa le ndlela isebenza kuphela uma ukujula kwembobo ecutshunguliwe kukuncane kunobubanzi bembobo kanye nemingcele yokusika incishisiwe. Ukwengeza, uhlobo olufanele lokupholisa, izinga lokugeleza nokucindezela kufanele kukhethwe ukuze kufane nobubanzi bebhithi yokubhoboza. Ngamathuluzi omshini angenayo isistimu yokupholisa ku-spindle, amapayipi okupholisa kufanele asetshenziswe. Lapho imbobo izocutshungulwa ijula, kuba nzima kakhulu ukususa ama-chips kanye nengcindezi yokupholisa edingekayo. Ngakho-ke, ukugeleza kokupholisa okuncane okunconywe umkhiqizi wokubhoboza kufanele kuqinisekiswe. Uma ukugeleza kokupholisa kunganele, ukudla komshini kufanele kuncishiswe.
