Iyini I-Twist Drill?

Ama-twist drill (okubuye abizwe ngokuthi ama-twist bits) asetshenziswa kakhulu kuzo zonke izinhlobo zamabhithi okubhoboza. Ama-twist drill azosika noma yini kusukela ngokhuni nasepulasitiki kuya kwensimbi nakokhonkolo. Zivame ukusetshenziselwa ukusika insimbi, futhi ngokuvamile zenziwe ngensimbi ye-M2 enesivinini esikhulu. Kuma-diameter afika cishe ku-1/2", ama-twist drill awawona nje kuphela amabhithi ashibhile kunawo wonke umuntu osebenza ngokhuni angawasebenzisa kodwa futhi anikezela ngokukhethwa okubanzi kakhulu kosayizi.

I-twist drill iyinduku yensimbi enobubanzi obuthile enemitshingo ezungezayo emibili, emithathu, noma emine egijima ingxenye enkulu yobude bayo. Ukubhoboza okunemitshingo emibili okokubhoboza okuyinhloko, kuyilapho ukubhoboza imitshingo emithathu kanye nemine kungokwandiswa kwezimbobo zabalingisi noma ezibhontshiwe esimweni sokukhiqiza. Ingxenye ephakathi kwemitshingo emibili ibizwa ngokuthi iwebhu, futhi iphuzu lakhiwa ngokukhululeka ukugaya iwebhu ibe i-engeli engu-59° ukusuka eksisi yokubhoboza, ehlanganisiwe engu-118°. Lokhu kwakha unqenqema lokusika olwehlele emaphethelweni omtshingo, olubizwa ngokuthi udebe. I-twist drill ayisebenzi kahle endaweni ngoba iwebhu ishiya isikhala esincane sokuphuma semfucumfucu (ebizwa ngokuthi i-swarf) futhi ngenxa yokuthi iphuzu linesivinini esiphansi uma kuqhathaniswa nendawo ezungezile. Ngalesi sizathu, uhlelo oluhle lokubhoboza izimbobo ezinkulu ukuqala ubhoboze u-1/4” noma ngaphansi bese ulandela ngokubhoboza ubukhulu obufunekayo.

Izinto zokwakha: Izinhloso ezijwayelekile zokuzivivinya zokusonta ezizosetshenziswa ekuzishayeleni okuphathekayo zitholakala ngamamaki ahlukene ensimbi enesivinini esikhulu kanye nensimbi ye-cobalt ne-carbide eqinile. Ama-twist drill bits emishini ezishintshayo atholakala ngensimbi ye-carbon, insimbi enesivinini esikhulu, i-carbide enetiphu, ne-carbide eqinile.

Ama-coatings: Izingcezu zokubhoboza inhloso evamile ziyatholakala nge-black oxide, i-bronze oxide, inhlanganisela ye-oxide emnyama neyethusi, kanye nezingubo ze-TiN. Ama-twist drill emishini ezenzakalelayo esizeni sethu asetshenziswa ngokhuni noma kumapulasitiki futhi awaboshiwe.

Kukhona ama-twist drill ahlukene aklanyelwe izinhlelo zokusebenza ezahlukene. Kodwa ngisho ne-twist drill efanele yohlelo oluhlosiwe ingaphuka uma isetshenziswe ngokungalungile. Lokhu kungaba nezizathu ezahlukene esizifingqe ngezansi.

Ama-Twist drills aklanyelwe izinhlelo zokusebenza ezihlukahlukene. Kuye ngokuthi ufuna ukubhoboza insimbi yesakhiwo noma insimbi enamandla amakhulu, kufanele ukhethe i-drill efanele. Uma ungakwenzi lokhu, i-drill ingase iphuke.

Sibala izizathu eziyisishiyagalombili zokuthi kungani izivivinyo zingaphuka:

1. Ukusebenzisa i-drill engalungile ukuze kubhojwe impahla

2. I-workpiece kanye ne-drill bekungaboshiwe ngokuqinile ngokwanele

3. Ukususwa kwe-chip okungekuhle

4. Isivinini sokusika kanye nezinga lokudla kusethwe ngokungalungile

5. Ikhwalithi embi ye-drill

6. Ububanzi obuncane/obukhulu be-twist drill

7. Akukho ukupholisa

8. Ukusebenzisa i-drill endaweni yokubhola ephathwayo esikhundleni sokubhola insika

Uma unaka izinkinga, ama-drill akho kufanele angonakaliswe futhi ahlale nawe isikhathi eside.

Ama-Solid Carbide Twist Drills Bits angamathuluzi okusika okudala izimbobo eziyindilinga endaweni yokusebenza. Sihlinzeka ngezinduku ze-carbide zekhwalithi ephezulu zokwenza ama-carbide twist drill. Uma ufuna i-carbide rod ephezulu, xhumana ne-ZZBETTER ukuze uthole amasampula wamahhala.
