Ukusetyenziswa kwe-twist drills kuhambelana ngqo nesitayela kunye nohlobo.Emarikeni, kukho iidrili ze-cobalt ezinentsimbi estainless, i-parabolic deep-hole twist drills, ii-twist ezinegolide, i-titanium-plated twist drills, i-high-speed steel twist drills, kunye ne-twist drill yexesha elide.Injongo yale mibhobho yokubhobhoza kukusika izixhobo zokugaya, ezinokuthi zisetyenziswe njengokugaya ikhonkrithi yokwakha, i-steel plate drilling, i-electronic industry drilling, njl.
Ukuqulunqwa kunye nesiphumo soLungiselelo lweTwist Drills
Twist drillsziveliswa ngokwemigangatho ye-twist drills, equkethe i-shank, intamo kunye nenxalenye yokusebenza.Kukho ii-angles ezi-6 ze-drill bits, kunye nee-engile ezahlukeneyo zineengile ezithile zokuchaneka kokomba kunye nokusebenza kakuhle.Ekubeni i-diameter ye-twist drill inqunyelwe yi-diameter yomngxuma, kwaye ngenxa yokuba i-spiral groove inokwenza i-drill core ibe mncinci, ukuqina komngxuma ogrunjiweyo kuphantsi kakhulu, isikhokelo somngxuma ogrunjiweyo asicacanga, kwaye i-axis ye-drill ye-drill iyancipha. umngxuma ujika lula.Ngoko ke, kunzima ukubeka iziko le-chisel edge kwaye i-drill bit ihamba, okukhokelela kwiimpazamo ezinkulu kwimilo kunye nokuma komngxuma.Ukongeza, ngenxa yokuba imiphezulu egobileyo yangaphambili nasemva ye-twist drill bit iyafana, kwaye i-angle yangaphambili kunye neegophe zangasemva zenqaku ngalinye le-edge yokusika ziyahluka, iimeko zokusika zimbi kwaye isantya asilingani, nto leyo ekugqibeleni ibangela. i-drill bit yokunxiba kunye nokuchaneka kokomba kuphantsi.Inqaku lokugqibela kukuba isantya sokusika esibangelwa ijika le-drill bit asifani, kwaye kulula ukuvelisa i-spiral debris efakwe kwi-workpiece, kunye ne-debris kunye nodonga lomngxuma luvelisa i-friction extrusion.Ekugqibeleni, umphezulu we-workpiece yomhlaba urhabaxa kakhulu.Yintoni enokugrunjwa?
1. Dmba isinyithi
Ukugaya isinyithi ngokuqhelekileyo kumnyamai-drill bit, kwaye i-drill bit ngokuqhelekileyo yenziwe ngentsimbi ephezulu.Ngokubanzi izinto zetsimbi (intsimbi yealloyi, intsimbi engaxutywanga, intsimbi etyhidiweyo, intsimbi etyhidiweyo, isinyithi esingenawo intsimbi), iintsimbi zokubhoboza zisetyenziswa kunye.
Nangona kunjalo, kulumkele ukugrumba ngaphezulu kwentsimbi.Isantya akufanele sibe phezulu kakhulu, kulula ukutshisa i-drill bit.Ngoku kukho iigolide ezigqunywe ngeefilimu zetsimbi ezinqabileyo ezinqabileyo ngaphandle, ezenziwe ngentsimbi yesixhobo kunye nezinye izinto, eziqiniswe kunyango lobushushu.Incam icolwa ngama-angles alinganayo kumacala omabini kwaye ihlehliswe kancinci ukwenza i-edge ebukhali.Intsimbi, intsimbi kunye ne-aluminiyam engazange yenziwe lukhuni ngonyango lobushushu.Phakathi kwazo, i-aluminium kulula ukunamathela kwi-drill bit kwaye idinga ukuthanjiswa ngamanzi anesepha xa ubhobhoza.
2. Yomba ikhonkrithi
Ukubhoboza imingxuma kwikhonkrithi kunye nelitye, sebenzisa i-percussion drill kunye ne-masonry drill, kunye nentloko ye-cutter ivame ukwenziwa nge-carbide.Amakhaya aqhelekileyo asebenzisa i-10mm yokomba ngesandla jikelele endaweni yokomba kudonga lwesamente.
3. Yomba iinkuni
Gqoka imingxuma emthini nge-drill workworking drill.I-woodworking drill bit inomthamo omkhulu wokusika kwaye ayifuni ubunzima obuphezulu besixhobo.Isixhobo sesixhobo ngokuqhelekileyo yintsimbi eqhelekileyo enesantya esiphezulu.Kukho incam encinci embindini wencam ye-drill, kwaye ii-angles zediagonal kumacala omabini zinkulu, okanye azikho engile.Isetyenziswe njengendawo esisigxina.Enyanisweni, izixhobo zentsimbi ziyakwazi ukugrumba iinkuni.Ngenxa yokuba iinkuni zitshisa ngokulula kwaye i-chips brittle ayilula ukuyikhupha, kufuneka unciphise kwaye uhlambulule ii-chips ngezikhathi ezithile.
4. Gqa iithayile kunye neglasi
Ithayilei-drill bitszisetyenziselwa ukugrumba imingxuma kwiithayile zeceramic kunye neglasi enobulukhuni obuphezulu.Isixhobo sesixhobo senziwe nge-tungsten-carbon alloy.Ngenxa yokuba isixhobo sinobunzima obuphezulu kunye nokuqina okungahambi kakuhle, kufuneka sisetyenziswe ngesantya esiphantsi kwaye ngaphandle kwempembelelo.
