Uhlobo lwe-End Mill

Kunezigaba ezimbalwa ezibanzi zamathuluzi okugcina nawokugaya ubuso akhona, njengokusika phakathi nendawo nokungasiki maphakathi (ukuthi umshini wokugaya ungathatha ukusikeka kokuphonseka);kanye nokuhlukaniswa ngenani lemitshingo;nge-helix angle;ngempahla;nangezinto zokumboza.Isigaba ngasinye singaphinde sihlukaniswe ngokusetshenziswa okukhethekile kanye nejometri ekhethekile.

I-engeli ye-helix ethandwa kakhulu, ikakhulukazi ukusika okuvamile kwezinto zensimbi, ngu-30 °.Okokuqedaizigayo zokugcina, kuvamile ukubona i-spiral more tight spiral, ene-helix angles 45° noma 60°.Izigayo zokuphela komtshingo eziqondile(i-helix angle 0°) isetshenziswa ezinhlelweni ezikhethekile, njengamapulasitiki okugaya noma izinhlanganisela ze-epoxy nengilazi.Izigayo zokuphela komtshingo eziqondile zazibuye zisetshenziswe ngokomlando ukusika insimbi ngaphambi kokusungulwa komshini wokuqeda umtshingo we-helical ngu-Carl A. Bergstrom we-Weldon Tool Company ngo-1918.

Kukhona izigayo ezinemitshingo eguquguqukayo ye-helix noma i-pseudo-random helix angle, kanye namajiyometri omtshingo angaqhubeki, ukusiza ukuhlephula izinto zibe izingcezu ezincane ngenkathi kusikwa (ukuthuthukisa ukuphuma kwe-chip nokunciphisa ubungozi bokuminyana) nokunciphisa ukusebenzisana kwethuluzi ekusikekeni okukhulu.Eminye imiklamo yesimanje ihlanganisa izici ezincane ezifana ne-chamfer yekona kanye ne-chipbreaker.Nakuba kubiza kakhulu, ngenxa yokuklama okuyinkimbinkimbi kanye nenqubo yokukhiqiza, enjaloizigayo zokugcinaingahlala isikhathi eside ngenxa yokuguga okuncane futhi ithuthukise ukukhiqiza kuhigh speed imishini(HSM) izicelo.

Sekuya ngokuya kuvama ukuthi izigayo eziqinile ezijwayelekile zishintshwe kufakwe ezonga kakhuluamathuluzi okusika(okuthi, nakuba kubiza kakhulu ekuqaleni, ukunciphisa izikhathi zokushintsha amathuluzi futhi kuvumele ukushintshwa kalula kwamaphethelo okusika agugile noma aphukile esikhundleni salo lonke ithuluzi).

Izigayo zokuphela zithengiswa ngazo zombili i-imperial kanye ne-metric shank kanye namadayamitha wokusika.E-USA, imethrikhi itholakala kalula, kodwa isetshenziswa kuphela kwezinye izitolo zemishini hhayi kwezinye;eCanada, ngenxa yokusondela kwezwe e-US, kuyafana okufanayo.E-Asia naseYurophu, ububanzi bemethrikhi bujwayelekile.
