Ukuze kwandiswe ubomi besikhunta, ubunzima bezinto eziza kunqunyulwa nazo zivame ukwanda.Ke ngoko, iimfuno eziphakamileyo zibekwe phambili kubomi besixhobo kunye nokusebenza kakuhle kumatshini okhawulezayo wezinto ezinobunzima obuphezulu.Ngesiqhelo, sinokukhetha ii-mills ekupheleni kumanqaku amathathu:
1. Khetha uhlobo lwesixhobo sokugquma ngokohlobo kunye nobunzima bomsebenzi oza kucutshungulwa.Ngokomzekelo, xa kusetyenzwa intsimbi yekhabhoni kunye nezinye izinto zokusebenza ezinobunzima obungaphantsi kwe-HRC40, i-MIRACLE40 yokugqoka kwi-Comprehensive Materials Company ingakhethwa.Xa kusetyenzwa i-alloy steel S, insimbi yesixhobo kunye nezinye izinto zokusebenza ezinobunzima malunga ne-HRC50, i-MIRACLE coating inokukhethwa.Xa machining workpieces kunye nobunzima obuphezulu, unokukhetha imilo yesixhobo, i-carbide material, kunye ne-coating, zonke ziyi-MIRACLE iingubo zobunzima obuphezulu bezinto ezinobunzima obuphezulu.
2. Khetha imilo yentamo yokusika isiphelo sokusila ngokwemilo yomsebenzi oza kucutshungulwa.Ubume bentamo yentsimbi yokugqibela yahlulahlulwe ngohlobo oluqhelekileyo, uhlobo lwentamo ende kunye nohlobo lwentamo ye-tapered, enokuthi ikhethwe ngokwenkqubo kunye nokuma kwendawo yokusebenza.Uhlobo olude lwentamo kunye nentamo ye-tapered ingasetyenziselwa ukumba nzulu, kwaye i-angle yokuphazamiseka kufuneka ithathelwe ingqalelo xa ukhetha phakathi kwezi zibini.Ngexesha elifanayo, xa kuthelekiswa nohlobo olude lwentamo, i-tapered neck end mill ine-rigidity ephezulu, enokuphucula iimeko zokusika kunye nokufezekisa ukuchaneka kakuhle kwe-machining.I-tapered neck end mill kufuneka ikhethwe kangangoko kunokwenzeka.
3. Khetha ii-mills zokuphela kunye nokuchaneka kwentloko yebhola eyahlukeneyo ngokuchaneka kwe-machining.Ukuchaneka kwe-arc ye-end Mills idla ngokuba yi-± 10 μm, kodwa kukwakho ne-end Mills ene-± 5 μm, enokuthi ikhethwe ngexesha lokucubungula.
