Ngokweendlela ezahlukeneyo zokusetyenzwa, ii-twist drills okwangoku kwimarike zahlulwe ngokwezi ntlobo zilandelayo:
1. I-rolled twist drill
Emva kokuba i-speed-speed steel ifudumale kwaye itshiswe ebomvu, i-shape ye-twist drill ikhutshwe ngokukhawuleza ngexesha elinye.Emva koko, itwist drill ifuna kuphela ukunyangwa ubushushu kwaye iphathwe umphezulu ukuze ilolwe intloko phambi kokuba isetyenziswe.
Inzuzo enkulu yenkqubo kukuphumelela okuphezulu kwemveliso kunye nokusetyenziswa ngokupheleleyo kwezinto eziluhlaza;isakhiwo sangaphakathi somzimba we-drill owenziweyo unokuqhubeka kwefiber, kwaye iinkozo zihlanjululwa, i-carbides ihanjiswa ngokulinganayo, kwaye ubunzima obomvu buphezulu.
Nangona kunjalo, inkqubo yokuqengqeleka nayo ineziphene ezicacileyo, oko kukuthi, umzimba we-drill kulula kakhulu ukuqhekeka, okanye kuya kubakho iintanda ezingelula ukuzibona, kwaye ngenxa yokuba zenziwe ngaxeshanye, ukuchaneka ngokubanzi kwe-drill. ayiyi kuba phezulu kakhulu.
Okwangoku, jijadrills nangokungokuqhelekileyo bamkele le ndlela yokucubungula, ngoko ke i-rolled twist drills kwimarike yorhwebo lwangaphandle ikakhulu iphakathi kunye nebakala eliphantsi.
2. I-groove isila ngasemvatwist drill
Ngenxa yento yokuba ukuqengqeleka kulula ukwenza iintanda, ngaphezu kwe-98% yeentanda kwi-rolling twist drills zenzeka kwindawo yokuhlangana komhlaba kunye ne-groove.
Nangona kunjalo, okokuqala ukukhupha i-groove edge ye-drill kwi-rolling Mill, kwaye emva koko ukugaya ngokucokisekileyo isangqa sangaphandle kwisixhobo somatshini, kusombulula ngokugqibeleleyo le ngxaki.
Kwaye ngenkqubo yokugaya kakuhle isangqa sangaphandle, kungekhona nje kuphela ukuba ingxaki yokuqhekeka ingasonjululwa, kodwa kunye nokuchaneka kwe-machining ye-drill bit kunye nokuchaneka kwe-radial circular runout kunokuphuculwa.
3. Umhlaba opheleleyotwist drill
Okwangoku, eyona nto iphambili iteknoloji yokugrumba i-twist emhlabeni, ii-twist drills zenziwe ngamavili okusila ukusuka ekusikeni kwezinto, ukuya kwi-groove grinding, ukugawula ngasemva, ukusika edge kunye nokusika i-angle.
I-twist drill ephantsi ngokupheleleyo kunye nepolishiweyo inenkangeleko entle kwaye egudileyo, kwaye imilinganiselo ephambili efana nokuphuma kweradial, ubukhulu obungundoqo, kunye nokunyuswa kobungqingqwa kulawuleke kakuhle kakhulu, kwaye ukuchaneka kuphezulu kakhulu.
Nangona kunjalo, enyanisweni, nje ukuba inkqubo yokuqengqeleka kunye nenqanaba lonyango lobushushu likhona, ukuqengqeleka kusengcono ngokwembono yokuqina.
