Uhlobo lwe-End Mill

Iindidi ezininzi ezibanzi zezixhobo zokuphelisa kunye nobuso-zokusila zikhona, ezifana nokusika iziko xa kuthelekiswa nokungasiki embindini (nokuba ilitye lingathatha ukusika); nokwahlulwa ngokweendidi ngenani lembande; nge-engile ye-helix; ngezinto eziphathekayo; nangezinto zokugquma. Udidi ngalunye lunokwahlulwa ngakumbi ngesicelo esithile kunye nejometri ekhethekileyo.

I-angle ye-helix eyaziwa kakhulu, ngokukodwa ukusika ngokubanzi kwezinto zetsimbi, yi-30 °. Ukugqibaisiphelo sokusila, kuqhelekile ukubona i-spiral eqinile ngakumbi, kunye ne-helix angles 45 ° okanye 60 °.Imizila yokuphela kwefluti ethe ngqo(i-helix angle 0 °) zisetyenziswa kwizicelo ezikhethekileyo, njengeeplastiki zokusila okanye i-composites ye-epoxy kunye neglasi. Imizila yokuphela kweflute ethe ngqo yayisetyenziswa ngokwembali ukusika isinyithi ngaphambi kokuyilwa kwe-helical flute end mill nguCarl A. Bergstrom weWeldon Tool Company ngo-1918.

Kukho ii-mills zokugqibela ezine-flute helix eguquguqukayo okanye i-pseudo-random helix angle, kunye neejiyometri zeflute ezingapheliyo, ukunceda ukuqhekeza imathiriyeli ibe ziziqwenga ezincinci ngelixa usika (ukuphucula ukufuduswa kwetshiphu kunye nokunciphisa umngcipheko wokufota) kunye nokunciphisa ukubandakanyeka kwesixhobo kumasikeko amakhulu. Olunye uyilo lwangoku luquka iimpawu ezincinci ezifana ne-chamfer yekona kunye ne-chipbreaker. Ngelixa zibiza kakhulu, ngenxa yoyilo oluntsonkothileyo kunye nenkqubo yokuvelisa, enjaloisiphelo sokusilainokuhlala ixesha elide ngenxa yokunxiba okuncinci kunye nokuphucula imveliso kwiisantya esiphezulu somatshini(HSM) izicelo.

Iya ixhaphaka into yokuba izingqusho zemveli eziqinileyo zitshintshwe zifakwe ezonga iindlekoizixhobo zokusika(okuthi, nangona kubiza kakhulu ekuqaleni, ukunciphisa amaxesha okutshintsha isixhobo kwaye kuvumele ukutshintshwa lula kweencam ezigugileyo okanye ezaphukileyo kunesixhobo sonke).

Ii-mills zokuphela zithengiswa kuzo zombini i-imperial kunye ne-metric shank kunye needayamitha zokusika. E-USA, i-metric ifumaneka ngokulula, kodwa isetyenziswa kuphela kwezinye iivenkile zoomatshini hayi ezinye; e Canada, ngenxa ukusondela lizwe ukuba US, kuyafana kuyinyaniso. E-Asia naseYurophu, i-metric diameters isemgangathweni.
