Izici Nokukhethwa Kwezingcezu Zokufaka Ezinenkomba

Izici nokukhethwa kwamabhithi okufaka anenkomba

Ibhithi yokufaka eyinkomba, eyaziwa nangokuthi i-shallow hole drill noma i-U drill, iyithuluzi elisebenzayo lokubhoboza izimbobo ezinobude obungaphansi kwezikhathi ezi-3. Isetshenziswe kabanzi kumathuluzi emishini ehlukene ye-CNC, izikhungo zomshini kanye nama-turret lathes eminyakeni yamuva. ku. I-drill bit ivamise ukugxunyekwa ngokulinganayo ngokufakwa okubili okunenkomba ukuze kwakhiwe imiphetho yangaphakathi nengaphandle, ecutshungulwa ngaphakathi kwembobo (kuhlanganise nendawo ephakathi) nangaphandle kwembobo (kuhlanganise nodonga lwembobo), njengoba kukhonjisiwe kuthebula elilandelayo. Uma ububanzi bembobo bukhulu, ama-blade amaningi angafakwa.

1. Ukuhlukaniswa komkhiqizo Ibhithi yokufaka ekhonjwa ingahlukaniswa ngokuya ngokuma kwensingo, umumo womtshingo, ukwakheka, nezici zokucubungula.

(1) Ngokokwakheka kwensingo, ingahlukaniswa ibe i-quadrangle, unxantathu oyi-convex, idayimane, i-hexagon, nokunye okunjalo.

(2) Ngokomtshingo ovamile wokusika, ungahlukaniswa ube izinhlobo ezimbili: umsele oqondile kanye ne-spiral groove.

(3) Ngokwesimo sesibambo sokubhoboza, singahlukaniswa sibe izinhlobo ezimbili: isibambo esiyicylindrical kanye ne-Morse taper bit.

(4) Ngokusho kwesakhiwo, ingahlukaniswa ngezinhlobo ezintathu: uhlobo olubalulekile, uhlobo lwe-modular kanye nekhanda lokusika kanye nomzimba wokusika ohlukile wohlobo lokuprakthiza.

2, izici zomkhiqizo

(1) Ifanele ukusika isivinini. Lapho machining steel, isivinini ukusika Vc kuyinto 80 - 120m / min; lapho umboza i-blade, isivinini sokusika i-Vc singama-150-300m / min, ukusebenza kahle kokukhiqiza kuyizikhathi ezingu-7-12 zokuprakthiza okujwayelekile.

(2) Ikhwalithi ephezulu yokucubungula. Ivelu yokuqina kwendawo ingafinyelela ku-Ra=3.2 - 6.3 um.

(3) I-blade ingafakwa ohlwini ukuze konge isikhathi esiyisizayo.

(4) Ukuphulwa kwe-chip okuhle. Ithebula lokuphulwa kwe-chip lisetshenziselwa ukuphulwa kwe-chip, futhi ukusebenza kokukhipha i-chip kuhle.

(5) Isakhiwo sokupholisa sangaphakathi samukelwa ngaphakathi kwe-drill shank, futhi impilo ye-drill blade iphakeme.

(6) Angeke isetshenziselwe ukubhoboza kuphela kodwa futhi isetshenziselwe isicefe nesicefe. Kwezinye izimo, ingasetshenziswa futhi njengethuluzi lokuguqula.
