Umqondo wokumba imbobo ejulile:

Embonini yokukhiqiza imishini, izimbobo ezingamacylindrical ezinombobo ukujula izikhathi ezingaphezu kweziyi-10 ubukhulu bembobo ngokuvamile zibizwa ngokuthi izimbobo ezijulile. Izimbobo ezijulile zivame ukuhlukaniswa zibe izinhlobo ezintathu: izimbobo ezijulile ezijwayelekile, izimbobo ezijulile eziphakathi kanye nezimbobo ezikhethekile ezijulile ngokwesilinganiso sokujula kokubhoboza kuya kububanzi bembobo (L/D).

1 L/D=10~20, ingumgodi ojulile ojwayelekile. Ivamise ukusetshenziselwa ukumba ama-twist amade kumshini wokubhoboza noma i-lathe.
2 L/D=20~30, ingeyembobo ejulile emaphakathi. Ivame ukucutshungulwa ku-lathe.
3 L/D=30~100, okungokujula kwembobo okukhethekile. Kumele icutshungulwe emshinini wokumba imbobo ejulile noma imishini ekhethekile kusetshenziswa umgodi ojulile wokubhoboza.

Ubunzima bokucubungula imbobo ejulile:

1. Isimo sokusika asikwazi ukubonwa ngokuqondile. Ukususwa kwe-chip yejaji kanye nokugqoka kwe-drill kuphela ngomsindo, ukusika ukubukela, ukubuka umthwalo womshini, ingcindezi kawoyela kanye neminye imingcele.
2. Ukusika ukushisa akudluliswa kalula.
3. Ukukhipha i-chip kunzima, futhi i-drill bit izolimala uma ihlangabezana nokuvinjelwa okusika.
4. Ngenxa yenduku ende yokubhoboza, ukungaqini kahle, nokudlidliza kalula, i-axis yembobo izophambuka, okuzothinta ukunemba komshini nokusebenza kahle kokukhiqiza.

Naka inkinga yokucubungula uwoyela we-crankshaft:

1 Ngokujwayelekile, ubude be-drill ephansi-phansi kanye nembobo yokuqondisa kusondelene kakhulu. Lapho ushintsha ithuluzi, u-opharetha kufanele alibone ngokucacile, ngaphandle kwalokho kungenzeka umcimbi wokushayisana kwethuluzi.
2 Lapho i-chamfer drill icubungula i-chamfering yembobo, ubukhulu be-chamfer yembobo buzohluka, ngokuvamile ngemva kokuba ithuluzi elisha lishintshiwe, ithuluzi ngokuvamile ligugile, (ithuluzi lingalungiswa ngokushintsha imingcele. ohlelweni).
3 Ukuncipha kwezinga lokugeleza kwe-MQL kuzobangela ukuphuka kwembobo ejulile futhi umkhiqizo uchithwe (lolu hlobo lwenkinga lungatholakala ekuhlolweni kwendawo, kanye nokusetshenziswa kwansuku zonke kwamafutha nakho kungatholakala).
4 Ngaphambi kokufaka imbobo ejulile ecijile, hlola ukuthi imbobo yokupholisa yangaphakathi ivinjiwe yini.
