Chii chinonzi HSS Twist Drill Bit?
HSS twist drill imhando yekuchera mudziyo wakagadzirwa neHigh-speed simbi inoshandiswa kugadzira simbi. HSS inokosha alloy simbi ine yakanakisa abrasion kuramba, kugadzikana kwemafuta, uye kucheka zvivakwa, zvichiita kuti ive yakakodzera kumabasa esimbi akadai sekuchera. A twist drill (inozivikanwawo sekuti auger kana spiral flute drill) chibooreso chine helical nyere chinobvumira kucheka machipisi kuti abude mugomba rekuchera nekukurumidza, kuderedza kukweshera uye kupisa panguva yekuchera nekuvandudza kuchera. Magadzirirwo eHSS twist drills anoita kuti ave akakodzera kune zvakasiyana-siyana zvakasiyana-siyana zvesimbi, kusanganisira simbi, aluminium, mhangura uye alloys, nezvimwewo pamwe chete nemhando yehuni machining.
Hunhu Hwepamusoro-Speed Steel Twist Drills
1. High Abrasion Resistance: High-speed simbi zvinhu zvinoratidzira zvakanakisa abrasion resistance, zvichibvumira kucheka kwekucheka kuti kugare kwakapinza kwenguva yakareba.
2. High Heat Stability: Simbi yepamusoro-soro inogona kushanda munzvimbo dzepamusoro-soro pasina kurasikirwa kukuru kwekuoma kana deformation.
3. Yakanakisa Kucheka Kuita: Iyo spiral groove dhizaini ye twist drills inobatsira pakucheka simbi kunobudirira uku ichideredza chip accumulation.
4. Kuvimbika Machining Quality: High-speed simbi twist zvibooresa zvinowanzopa emhando yepamusoro akaboorwa maburi ane mativi chaiwo uye nzvimbo dzakatsetseka.
HSS Types dzatakashandisa kune yedu Twist Drills
Magiredhi makuru eHSS atinoshandisa ndeaya: M42, M35, M2, 4341, 4241.
Pane mimwe misiyano pakati pavo, inonyanya kuenderana nemakemikari avo, kuoma, kugadzikana kwekupisa uye nzvimbo dzekushandisa. Pazasi pane misiyano mikuru pakati peaya mamakisi eHSS:
1. M42 HSS:
M42 ine 7% -8% cobalt (Co), 8% molybdenum (Mo) uye mamwe alloys. Izvi zvinopa zviri nani abrasion kuramba uye kugadzikana kwekupisa. M42 kazhinji ine kuomarara kwepamusoro, uye kuomarara kwayo kwerockwell ndeye 67.5-70(HRC) iyo inogona kuwanikwa nehunyanzvi hwekurapa kupisa.
2. M35 HSS:
M35 ine 4.5% -5% cobalt uye zvakare ine yakakura abrasion kuramba uye kugadzikana kwekupisa. M35 yakaoma zvishoma pane yakajairwa HSS uye kazhinji inochengetedza kuomarara kwebetweeb 64.5 uye 67.59(HRC). M35 yakakodzera kucheka zvinhu zvinonamira sesimbi isina tsvina.
3. M2 HSS:
M2 ine yakakwira tungsten (W) uye molybdenum (Mo) uye ine yakanaka yekucheka zvivakwa. Kuoma kweM2 kunowanzo kuve muhuwandu hwe63.5-67 (HRC), uye inokodzera kugadzirwa kwesimbi inoda zvakanyanya zvinodiwa.
4. 4341 HSS:
4341 HSS isimbi yekumhanya kwazvo ine yakaderera zvishoma alloy zvemukati zvinoenderana nem2. Iko kuomarara kunowanzo chengetwa pamusoro pe63 HRC uye inokodzera general simbi kushanda mabasa.
5. 4241 HSS:
4241 HSS zvakare yakaderera alloy HSS ine mashoma alloying zvinhu. Iko kuomarara kunowanzo chengetwa kwakatenderedza 59-63 HRC uye inowanzo shandiswa simbi yekushanda nekuchera.
Kusarudza giredhi rakakodzera reHSS zvinoenderana nezvinodiwa zvako zvekushandisa uye rudzi rwezvinhu zvinogadziriswa. Kuoma, abrasion resistance uye kugadzikana kwekushisa ndizvo zvinhu zvinokosha pakusarudza.
