I-Drill bit sisixhobo esijikelezayo esinamandla okusika ekupheleni kwentloko.Ngokuqhelekileyo yenziwe nge-carbon steel SK okanye i-high speed steel SKH2, i-SKH3 kunye nezinye izinto ngokugaya okanye ukuqengqeleka kwaye emva koko zicinywe emva kokugaya.Isetyenziselwa ukugaya isinyithi okanye ezinye izinto.Inoluhlu olubanzi kakhulu lokusetyenziswa, lunokusetyenziswa kumatshini wokugaya, i-lathe, umatshini wokugaya, u-drill ngesandla kunye nezinye izixhobo.Amasuntswana e-Drill angahlelwa ngolu hlobo lulandelayo.
A. Ukuhlelwa ngokwesakhiwo
1. I-Integral drill bit: i-drill top, i-drill body kunye ne-drill shank yenziwe ngezinto ezifanayo.
2. Ukuphelisa i-welding drill: i-bit top of the drill ifakwe kwi-carbide.
B. Ukuhlelwa ngokwe-drill shank
1, i-shank drill ethe tye: i-drill idayamitha ye-φ13.0mm kwaye ngaphantsi zi-shank ezithe tye.
I-2, i-taper shank drill: i-drill shank imile, ngokubanzi i-taper yayo yi-Morse taper.
C, ngokusetyenziswa kokuhlelwa
I-1, i-bit center: ngokubanzi isetyenziselwa ukubhola phambi kwendawo ephakathi, i-cone yangaphambili ye-60 °, 75 °, 90 °, njl.
2. I-twist drill: eyona nto isetyenziswa kakhulu kwi-drill bit kwimveliso yemizi-mveliso.
I-3, i-super hard drill bit: ngaphambi kokuphela komzimba wokomba okanye yonke into eyenziwe ngesixhobo se-alloy enzima kakhulu, esetyenziselwa ukusetyenzwa kwezinto zokomba.
4. I-Oil hole drill: kukho imingxuma emibini kwi-drill body, kwaye i-fluid yokusika ifikelela kwi-cutting edge part ngokusebenzisa umngxuma ukususa ubushushu kunye ne-chips.Ukusetyenziswa kwe-drill bit ngokuqhelekileyo kuzaliswa ngezinto zokupholisa ezifana nolwelo lokusika.
I-5, i-deep hole drill: eyona yakuqala isetyenziselwa ukusetyenzwa kwemvulophu kunye nelitye, ekwabizwa ngokuba yi-barrel drill.I-gun drill bit yi-groove eqondileyo, kwaye ikota yetyhubhu ejikelezayo iyasikwa ukuvelisa ukukhutshwa kwe-chip.Ukuqina kunye nesantya esiphezulu sentsimbi:
I-6, i-drill reamer: isiphelo esingaphambili se-drill, isiphelo esingasemva se-reamer.Idayamitha ye-drill kunye nobubanzi be-reamer yahluke kuphela kumda womngxuma ophindwe kabini, kwaye kukho ukusetyenziswa okuxubeneyo kwe-drill kunye ne-screw tapping, ngoko ke ikwabizwa ngokuba yi-mixed drill.
7. I-Taper drill: I-taper drill ingasetyenziswa xa kusetyenzwa i-port yesondlo sokubumba.
I-8, i-cylindrical hole drill: siyibiza ngokuba yi-countersunk head milling cutter, isiphelo sangaphambili se-drill sinedamitha encinci ebizwa ngokuba yintonga yomzila.
I-9, i-conical hole drill: ukubhola umngxuma we-conical, i-Angle yayo yangaphambili yi-90 °, i-60 °, njl.
I-10, i-drill ye-triangle: i-drill esetyenziswa ngamathambo ombane, i-drill shank eyenziwe ngobuso obunxantathu ukwenzela ukuba i-chuck ilungiswe.
