Chii chinonzi HSS Twist Drill Bit?
HSS twist drill rudzi rwechishandiso chekuboorera chakagadzirwa nesimbi inokurumidza kushandiswa pakugadzira simbi. HSS isimbi yakakosha ye alloy ine simba rekudzivirira kukwesha, kugadzikana kwekupisa, uye hunhu hwekucheka, zvichiita kuti ive yakakodzera mabasa ekugadzira simbi akadai sekuboorera. Twist drill (inozivikanwawo se auger kana spiral flute drill) iboorera rine helical flutes inobvumira kucheka machipisi kubuda mugomba rekuboorera nekukurumidza, zvichideredza kukweshana nekupisa panguva yekuboorera uye kuvandudza kushanda zvakanaka kwekuboorera. Dhizaini yema HSS twist drills inoita kuti akwanise kushandiswa mumhando dzakasiyana dzesimbi, kusanganisira simbi, aruminiyamu, mhangura uye alloys, nezvimwewo pamwe nekugadzira mhando dzehuni.
Hunhu hweHigh-Speed Steel Twist Drills
1. Kuramba Kukwesha Kwesimbi: Zvinhu zvesimbi zvinomhanya zvakanyanya zvinoratidza kukwesha kwakanaka, zvichiita kuti mipendero yekucheka irambe yakapinza kwenguva yakareba.
2. Kugadzikana Kwekupisa Kwakanyanya: Simbi inomhanya zvikuru inogona kushanda munzvimbo dzinopisa zvakanyanya pasina kurasikirwa nekuomarara kana kushanduka kwakakosha.
3. Kucheka Kwakanaka Kwazvo: Dhizaini yemabhora emugero anotenderera inobatsira pakucheka simbi zvinobudirira ukuwo ichideredza kuunganidzwa kwemachipisi.
4. Hunhu Hwakavimbika hweMachina: Mabhora ekumonera simbi anomhanya zvikuru anowanzo buritsa maburi akaboorwa emhando yepamusoro ane saizi chaiyo uye nzvimbo dzakatsetseka.
Mhando dzeHSS dzatakashandisa paTwist Drills dzedu
Magiredhi makuru eHSS atinoshandisa ndeaya: M42, M35, M2, 4341, 4241.
Pane misiyano pakati pazvo, kunyanya ine chekuita nekuumbwa kwemakemikari azvo, kuomarara kwazvo, kugadzikana kwekupisa uye nzvimbo dzekushandiswa kwazvo. Heano misiyano mikuru pakati pemagiredhi aya eHSS:
1. M42 HSS:
M42 ine 7%-8% cobalt (Co), 8% molybdenum (Mo) nedzimwe alloys. Izvi zvinoita kuti irambe kusimba uye igare zvakanaka pakupisa. M42 inowanzova nekuomarara kwakanyanya, uye kuomarara kwayo kwedombo remugungwa i67.5-70 (HRC) izvo zvinogona kuwanikwa nekushandisa nzira dzekurapa kupisa.
2. M35 HSS:
M35 ine 4.5%-5% cobalt uye ine simba guru rekudzivirira kukwesha uye kugadzikana kwekupisa. M35 yakaoma zvishoma pane HSS yakajairika uye inowanzo chengetedza kuomarara pakati pe64.5 ne67.59(HRC). M35 yakakodzera kucheka zvinhu zvinonamira zvakaita sesimbi isingatsvi.
3. M2 HSS:
M2 ine tungsten (W) yakawanda uye molybdenum (Mo) uye ine hunhu hwakanaka hwekucheka. Kuomarara kweM2 kunowanzova pakati pe63.5-67 (HRC), uye yakakodzera kugadzirwa kwesimbi dzinoda zvinodiwa zvakanyanya.
4. 4341 HSS:
4341 HSS isimbi inomhanya zvikuru ine alloy iri pasi zvishoma kana tichienzanisa ne m2. Kuoma kwayo kunowanzo chengetwa pamusoro pe 63 HRC uye kwakakodzera mabasa esimbi akajairika.
5. 4241 HSS:
4241 HSS imhando yeHSS ine alloy shoma ine zvinhu zvishoma zvinosanganisa alloy. Kuoma kwayo kunowanzo chengetedzwa pa 59-63 HRC uye kunowanzo shandiswa pakugadzira simbi nekuchera.
Kusarudza giredhi rakakodzera reHSS zvinoenderana nezvaunoda kushandisa uye rudzi rwezvinhu zvinoda kugadziriswa. Kuomarara, kuramba kukwesha uye kugadzikana kwekupisa ndizvo zvinhu zvikuru pakusarudza.
