Uhlobo lwe-End Mill

Kukho iindidi ezininzi ezibanzi zezixhobo zokusika ezipheleleyo nezijongene nazo, ezifana nokusika phakathi ngokuchasene nokungasikisi phakathi (nokuba i-mill ingakwazi na ukusika ngokuntywila); kunye nokwahlula ngokwenani leeflute; nge-engile ye-helix; ngezinto eziphathekayo; kunye nezinto zokugquma. Udidi ngalunye lunokwahlulwa ngakumbi ngokusetyenziswa okuthile kunye nejometri ekhethekileyo.

I-engile ye-helix ethandwayo kakhulu, ingakumbi xa kusikwa izinto zesinyithi ngokubanzi, yi-30°. Ukugqibaiifektri zokugqibela, kuqhelekile ukubona i-spiral eqinileyo, ene-engile ze-helix ezingama-45° okanye ezingama-60°.Iifektri zokuphela kweflute ezithe tye(i-helix angle 0°) zisetyenziswa kwizicelo ezikhethekileyo, ezifana neeplastiki zokugaya okanye izinto ezidityanisiweyo ze-epoxy kunye neglasi. Ii-stright flute end mills zazisetyenziswa nakwimbali yokusika isinyithi ngaphambi kokuba kuqalwe i-helical flute end mill nguCarl A. Bergstrom weWeldon Tool Company ngo-1918.

Kukho ii-end mills ezine-flute helix eguquguqukayo okanye i-pseudo-random helix angle, kunye ne-discontinuous flute geometries, ukunceda ukuqhekeza izinto zibe ziingceba ezincinci ngelixa zisika (ukuphucula ukuphuma kwee-chip kunye nokunciphisa umngcipheko wokuxinana) kunye nokunciphisa ukubandakanyeka kwezixhobo kwiindawo ezinkulu. Ezinye iindlela zanamhlanje ziquka iimpawu ezincinci ezifana ne-corner chamfer kunye ne-chipbreaker. Nangona zibiza kakhulu, ngenxa yoyilo oluntsonkothileyo kunye nenkqubo yokuvelisa, ezifanaiifektri zokugqibelaingahlala ixesha elide ngenxa yokungonakali kangako kwaye iphucule imvelisoimishini ekhawulezayoizicelo (HSM).

Kuye kuqheleka ngakumbi ukuba ii-solid end mills zemveli zitshintshwe zifakwe ezingabizi kakhulu.izixhobo zokusika(ekuthi, nangona ibiza kakhulu ekuqaleni, inciphise amaxesha okutshintsha izixhobo kwaye ivumele ukuba kube lula ukutshintsha imiphetho yokusika egugileyo okanye ephukileyo endaweni yesixhobo sonke).

Ii-End mills zithengiswa zombini ngee-imperial kunye ne-metric shank kunye nee-cutting diameters. E-USA, i-metric ifumaneka ngokulula, kodwa isetyenziswa kuphela kwezinye iivenkile zoomatshini kwaye hayi kwezinye; eKhanada, ngenxa yokuba ilizwe likufutshane ne-US, kuyafana. E-Asia naseYurophu, ii-metric diameters ziqhelekile.
