Iyini i-HSS Twist Drill Bit?
I-HSS twist drill iwuhlobo lwethuluzi lokubhola elenziwe ngensimbi enesivinini esikhulu esetshenziselwa ukucubungula insimbi. I-HSS iyinsimbi ekhethekile ye-alloy ekwazi ukumelana nokuhuzuka okuhle kakhulu, ukuzinza kokushisa, kanye nezakhiwo zokusika, okuyenza ilungele imisebenzi yensimbi efana nokubhola. I-twist drill (eyaziwa nangokuthi i-auger noma i-spiral flute drill) iwumshini wokubhoboza onomtshingo we-helical ovumela ama-chips okusika ukuthi aphume embobeni yokubhoboza ngokushesha, enciphisa ukungqubuzana nokushisa ngesikhathi sokubhola futhi ithuthukisa ukusebenza kahle kokubhola. Idizayini ye-HSS twist drill ibenza bafanelekele inhlobonhlobo yezinto zensimbi ezehlukene, okuhlanganisa insimbi, i-aluminium, ithusi nama-alloys, njll. kanye nomshini wohlobo lwezinkuni.
Izimpawu Zemishini Yensimbi Yesivinini Ephakeme Yokusonteka
1. I-High Abrasion Resistance: Izinto zensimbi ezinesivinini esiphezulu zibonisa ukumelana nokuhuzuka okuhle kakhulu, okuvumela imiphetho yokusika ukuthi ihlale ibukhali isikhathi eside.
2. Ukuqina Kokushisa Okuphezulu: Insimbi enesivinini esiphezulu ingasebenza ezindaweni ezishisa kakhulu ngaphandle kokulahlekelwa okuphawulekayo kokuqina noma ukuguqulwa.
3. Ukusebenza Okuhle Kakhulu Kokusika: Idizayini ye-spiral groove ye-twist drill inomthelela ekusikeni kwensimbi okuphumelelayo kuyilapho kunciphisa ukuqoqwa kwe-chip.
4. Ikhwalithi Yemishini Ethembekile: Izimbobo zensimbi ezinesivinini esiphezulu ngokuvamile ziletha izimbobo ezibhobhile zekhwalithi ephezulu ezinobukhulu obunembile kanye nezindawo ezibushelelezi.
Izinhlobo ze-HSS Esizisebenzise Ekushayeleni Kwethu I-Twist
Amabanga ayinhloko e-HSS esiwasebenzisayo yilawa: M42, M35, M2, 4341, 4241.
Kukhona umehluko phakathi kwabo, ikakhulukazi okuhlobene nokwakheka kwamakhemikhali abo, ubulukhuni, ukuzinza kokushisa kanye nezindawo zokufaka isicelo. Ngezansi umehluko omkhulu phakathi kwala mabanga e-HSS:
1. M42 HSS:
I-M42 iqukethe u-7% -8% we-cobalt (Co), u-8% we-molybdenum(Mo) namanye ama-alloys. Lokhu kuyinikeza ukumelana nokuhuzuka okungcono kanye nokuzinza kokushisa. I-M42 ivamise ukuba nobulukhuni obuphakeme, futhi ubulukhuni bayo be-rockwell bungu-67.5-70(HRC) obungazuzwa ngamasu okwelapha ukushisa.
2. M35 HSS:
I-M35 iqukethe i-cobalt engu-4.5% -5% futhi inokumelana nokuhubeka okukhulu kanye nokuzinza kokushisa. I-M35 ilukhuni kancane kune-HSS evamile futhi ngokuvamile igcina ubulukhuni be-betweeb 64.5 kanye no-67.59(HRC). I-M35 ifanele ukusika izinto ezinamathelayo njengensimbi engagqwali.
3. M2 HSS:
I-M2 iqukethe amazinga aphezulu e-tungsten (W) ne-molybdenum (Mo) futhi inezici zokusika ezinhle. Ukuqina kwe-M2 kuvame ukuba ku-63.5-67(HRC), futhi ifanele ukwenziwa kwensimbi edinga izidingo eziphakeme.
4. 4341 HSS:
I-4341 HSS iyinsimbi enesivinini esikhulu enokuqukethwe kwe-alloy ephansi kancane okuhlobene ne-m2. Ukuqina ngokuvamile kugcinwa ngaphezu kuka-63 HRC futhi kulungele imisebenzi evamile yokusebenza kwensimbi.
5. 4241 HSS:
I-4241 HSS futhi iyingxubevange ephansi HSS equkethe izakhi ezincane zengxubevange. Ukuqina ngokuvamile kugcinwa cishe ku-59-63 HRC futhi kuvame ukusetshenziselwa ukusebenza kwensimbi evamile kanye nokubhola.
Ukukhetha ibanga elifanele le-HSS kuncike ezidingweni zakho ezithile zohlelo lokusebenza kanye nohlobo lwezinto ezizocutshungulwa. Ukuqina, ukumelana nemihuzuko kanye nokuzinza kokushisa yizici ezibalulekile ekukhethweni.
