Kuyini i-HSS Twist Drill Bit?
I-HSS twist drill uhlobo lwethuluzi lokubhoboza elenziwe ngensimbi esheshayo esetshenziselwa ukucubungula insimbi. I-HSS iyinsimbi ekhethekile ye-alloy enokumelana okuhle kakhulu nokuguguleka, ukuzinza kokushisa, kanye nezakhiwo zokusika, okwenza ifaneleke kakhulu emisebenzini yokusebenza kwensimbi njengokubhoboza. I-twist drill (eyaziwa nangokuthi i-auger noma i-spiral flute drill) iyi-drill ene-helical flutes evumela ama-chips okusika ukuphuma emgodini wokubhoboza ngokushesha, kunciphisa ukungqubuzana nokushisa ngesikhathi sokubhoboza futhi kuthuthukiswe ukusebenza kahle kokubhoboza. Ukwakheka kwama-HSS twist drills kuwenza afaneleke ezintweni eziningi ezahlukene zensimbi, kufaka phakathi insimbi, i-aluminium, ithusi kanye ne-alloys, njll. kanye nomshini wokwakha uhlobo lwezinkuni.
Izici Zokujikijela Kwensimbi Esheshayo Esheshayo
1. Ukumelana Nokuguguleka Okuphezulu: Izinto zensimbi ezisheshayo zibonisa ukumelana okuhle kakhulu nokuguguleka, okuvumela imiphetho yokusika ukuthi ihlale ibukhali isikhathi eside.
2. Ukuzinza Kokushisa Okuphezulu: Insimbi yesivinini esiphezulu ingasebenza ezindaweni ezishisa kakhulu ngaphandle kokulahlekelwa okukhulu kobulukhuni noma ukuguquka.
3. Ukusebenza Okuhle Kakhulu Kokusika: Umklamo we-spiral groove wama-twist drills usiza ekusikeni kwensimbi okuphumelelayo ngenkathi kunciphisa ukuqongelela kwama-chip.
4. Ikhwalithi Yomshini Ethembekile: Ama-drill ensimbi asheshayo ajikayo ngokuvamile aletha imigodi ebholiwe esezingeni eliphezulu enobukhulu obuqondile kanye nezindawo ezibushelelezi.
Izinhlobo ze-HSS Esazisebenzisa Ekuzilolongeni Kwethu
Amabanga ayinhloko e-HSS esiwasebenzisayo yilawa: M42, M35, M2, 4341, 4241.
Kukhona umehluko phakathi kwazo, ikakhulukazi ohlobene nokwakheka kwamakhemikhali azo, ubulukhuni, ukuzinza kokushisa kanye nezindawo zokusetshenziswa. Ngezansi umehluko omkhulu phakathi kwalezi zigaba ze-HSS:
1. I-M42 HSS:
I-M42 iqukethe i-cobalt (Co) engu-7%-8%, i-molybdenum (Mo) engu-8% kanye nezinye izinhlobo ze-alloy. Lokhu kuyinika ukumelana okungcono kokuguguleka kanye nokuqina kokushisa. I-M42 ivame ukuba nobunzima obuphezulu, kanti ubunzima bayo be-rockwell bungu-67.5-70(HRC) obungatholakala ngamasu okwelapha ukushisa.
2. I-M35 HSS:
I-M35 iqukethe i-cobalt engu-4.5%-5% futhi inokumelana okukhulu kokuguguleka kanye nokuqina kokushisa. I-M35 ilukhuni kancane kune-HSS evamile futhi ivame ukugcina ubulukhuni obuphakathi kuka-64.5 no-67.59(HRC). I-M35 ifaneleka ukusika izinto ezinamathelayo njengensimbi engagqwali.
3. I-M2 HSS:
I-M2 iqukethe amazinga aphezulu e-tungsten (W) kanye ne-molybdenum (Mo) futhi inezakhiwo ezinhle zokusika. Ubulukhuni be-M2 buvame ukuba sebangeni eliphakathi kuka-63.5-67(HRC), futhi ifaneleka ekusetshenzisweni kwezinsimbi ezidinga izidingo eziphakeme.
4. 4341 HSS:
I-4341 HSS iyinsimbi yesivinini esiphezulu enokuqukethwe kwe-alloy okuphansi kancane uma kuqhathaniswa ne-m2. Ubulukhuni ngokuvamile bugcinwa ngaphezu kwe-63 HRC futhi bufanelekela imisebenzi yokusebenza yensimbi ejwayelekile.
5. 4241 HSS:
I-4241 HSS nayo iyi-HSS engxubevange ephansi equkethe izinto ezingaxubeki kakhulu. Ubulukhuni ngokuvamile bugcinwa cishe ku-59-63 HRC futhi ngokuvamile busetshenziselwa ukusebenza kwensimbi evamile kanye nokubhoboza.
Ukukhetha izinga elifanele le-HSS kuncike ezidingweni zakho ezithile zohlelo lokusebenza kanye nohlobo lwezinto okufanele zicutshungulwe. Ukuqina, ukumelana nokuguguleka kanye nokuqina kokushisa yizinto ezibalulekile ekukhetheni.
