Inqubo yokumba

01
Izici zokumba
I-drill ngokuvamile inemiphetho emibili yokusika, enqunywa ngenkathi i-drill iphenduka.I-engeli ye-rake yebhithi inkulu futhi inkulu ukusuka eksisi emaphakathi kuya onqenqemeni lwangaphandle.Uma iseduze nendilinga yangaphandle, ijubane lokusika le-bit liphezulu.Ijubane lokusika liyancipha liye enkabeni, futhi isivinini sokusika sesikhungo se-rotary se-bit siyi-zero.I-cross edge ye-drill itholakala eduze kwe-axis yesikhungo se-rotary, futhi i-rake eseceleni I-Angle ye-cross edge inkulu, asikho isikhala sokubekezelelana kwe-chip, futhi isivinini sokusika siphansi, ngakho-ke sizokhiqiza ukumelana okukhulu kwe-axial. .Ukumelana nokusika kungancishiswa futhi ukusebenza kokusika kungathuthukiswa kakhulu uma unqenqema lonqenqema olunqamulayo lupholishwa lube uhlobo A noma C ku-DIN1414 futhi umkhawulo wokusika eduze kwe-axis emaphakathi yi-Angle rake elihle.

Ngokusho komumo we-workpiece, impahla, isakhiwo, umsebenzi, njll., ukubhola kungahlukaniswa ngezinhlobo eziningi, njenge-HSS drill (i-twist drill, i-group drill, i-flat drill), i-hard carbide drill, i-indexable drill yembobo engajulile, i-deep hole drill. , ukubhoboza isidleke kanye nokubhola kwekhanda okulungisekayo.

Ukuphulwa kwe-chip nokususwa kwe-chip
Ukusikwa kwe-bit kwenziwa emgodini omncane, futhi i-chip kufanele ikhishwe nge-groove enqenqemeni yebhithi, ngakho-ke ukwakheka kwe-chip kunethonya elikhulu ekusebenzeni kokusika kwebhithi.I-chip yokwakheka kwe-chip evamile, i-tubular chip, i-chip yenaliti, i-conical spiral chip, i-ribbon chip, i-fan chip, i-powder chip nokunye.
Uma umumo we-chip ungalungile, izinkinga ezilandelayo zizokwenzeka:

① Ama-chips amahle avimba umsele wonqenqema, athinta ukunemba kokumba, anciphise impilo yokumba, futhi enze i-drill iphuke (njengamaphuphu oyimpuphu, ama-fan chips, njll.);
② Ama-chips amade azungeze i-drill, avimbe ukusebenza, abangele ukulimala noma avimbele uketshezi olusikayo emgodini (njengama-spiral chips, ama-ribbon chips, njll.).

Indlela yokuxazulula inkinga ye-chip shape engalungile:
① Ingasetshenziswa ngokuhlukana noma ngokuhlanganyela ukukhulisa okuphakelayo, okuphakelayo ngezikhathi ezithile, unqenqema lokugaya, i-chip breaker nezinye izindlela zokuthuthukisa ukuphulwa kwe-chip nomphumela wokususa, ukuqeda izinkinga ezibangelwa ukusika kwe-chip.
I-professional chip breaker drill ingasetshenziselwa ukubhola.Isibonelo, ukwengeza i-chip breaker blade emgodini webhithi kuzophula i-chip ibe imfucumfucu ekhishwa kalula.Imfucumfucu isuswa kahle eduze komsele ngaphandle kokuvaleka emseleni.Ngakho-ke, i-chip breaker entsha ingafinyelela imiphumela yokusika ebushelelezi kunezinhlamvu zendabuko.

Ngesikhathi esifanayo, insimbi emfushane ye-scrap iron yenza ukupholisa kugeleze kuphuzu lokubhoboza kalula, okuthuthukisa ngokwengeziwe umphumela wokuqeda ukushisa nokusebenza okusikayo enqubweni yokwenza imishini.Futhi ngenxa yokuthi i-chip breaker entsha idlula kuwo wonke umsele webhithi, igcina umumo nokusebenza kwayo ngemva kokugaya okuphindaphindiwe.Ngaphezu kwalokhu kuthuthukiswa kokusebenza, kufanele kuphawulwe ukuthi ukwakheka kuthuthukisa ukuqina komzimba wokubhoboza futhi kwandisa kakhulu inani lemigodi ebhojwe ngaphambi kokunquma okukodwa.

Ukunemba kokumba
Ukunemba kwembobo ikakhulukazi kwakhiwa usayizi wokuvula, ukunemba kwendawo, i-coaxiality, ukuzungeza, ukuhwaqeka kwendawo kanye ne-orifice burr.
Izinto ezithinta ukunemba kwezimbobo ezibhoboziwe ngesikhathi sokumba:

(1) Ukunemba kwe-Bit clamping nezimo zokusika, njengesiqeshana sokusika, isivinini sokusika, okuphakelayo, uketshezi lokusika, njll.;
② Usayizi omncane nokuma, njengobude bebhithi, umumo wonqenqema, umumo owumongo, njll.;
(3) umumo we-workpiece, njengokuma kwe-orifice side, i-orifice shape, ukujiya, isimo sokugoqa, njll.
