HSS Drill
Meiwha Drill Tools e fana ka HSS Drill le Alloy Drill.The HSS Twist Drill Bit Ground ke ea ho cheka ka tšepe ka ho nepahala ho fetisisa.Thepa e pepesitsoeng ea 135-degree self-centring-point e kopanya ho itšeha ka mafolofolo le setsi se phethahetseng ntle le ho lelera, ho fana ka ho nepahala ho fetisisa.Ntlha ea ho arohana e boetse e felisa tlhoko leha e le efe ea ho phunya pele kapa ho phunya sefofane ho fihlela ho 10 mm.Karolo ena e nepahetseng ea fatše e entsoeng ka HSS (tšepe ea lebelo le phahameng) e thusa ho fihla ho 40% lebelo la ho cheka ka lebelo le ho fihla ho 50% khatello e tlase ea phepelo ho feta likotoana tsa ho cheka tsa HSS tse nang le likarolo tsa chisel.Sekhechana sena se etselitsoe ho phunya masoba ka tšepe e kopantsoeng le e seng alloyed, tšepe e entsoeng ka tšepe, tšepe e entsoeng ka tšepe, tšepe e entsoeng ka sintered, tšepe ea tšepe e bonolo, tšepe e sa tsitsang le polasetiki e thata.E na le cylindrical shank system (shank e lekanang le bophara ba ho cheka) 'me e reretsoe ho sebelisoa libakeng tsa ho cheka le ho cheka bakhanni.
HSS Twist Drill Bit Ground e hlahiswa ho DIN 1897. Biti ya ho phunya ke Mofuta wa N (sekgutlo sa folutu) se nang le ntlha ya 118-degree le ho mamella bophara ba h8.
Litlhokomelo tsa ho sebelisa lisebelisoa tsa carbide tse samente
1) Carbide e entsoeng ka samente ke thepa e thata le e brittle, e brittle le e senyehileng ka tlas'a matla a feteletseng kapa liphello tse itseng tsa khatello ea kelello ea sebakeng seo, 'me e na le mapheo a bohale.
2) Boholo ba li-carbide tse entsoeng ka samente haholo-holo ke tungsten le cobalt.Lisebelisoa li na le boima bo phahameng, kahoo li lokela ho tšoaroa e le lintho tse boima nakong ea lipalangoang le polokelo.
3) Carbide e entsoeng ka samente le tšepe li na le li-coefficients tse fapaneng tsa ho atolosa mocheso.E le ho thibela khatello ea kelello hore e se ke ea senyeha, tlhokomelo e lokela ho lefshoa ho tjheseletsa ka mocheso o loketseng.
4) Lisebelisoa tsa ho itšeha tsa Carbide li lokela ho bolokoa sebakeng se omileng, hole le sepakapaka se senyang.
5) Nakong ea ts'ebetso ea ho itšeha ea lisebelisoa tsa carbide tse entsoeng ka samente, li-chips, chips, joalo-joalo li ke ke tsa thibeloa.Ka kopo, lokisa lisebelisoa tse hlokahalang tsa ts'ireletso ea basebetsi pele o etsa mochini.
6) Haeba mokelikeli o pholileng kapa lisebelisoa tsa pokello ea lerōle li sebelisoa ts'ebetsong ea ho itšeha, ha ho nahanoa ka bophelo ba tšebeletso ea mochine oa mochine le lisebelisoa tsa ho itšeha, ka kopo sebelisa thepa ea ho bokella mokelikeli kapa lerōle ka nepo.
7) Ka kopo emisa ho sebelisa sesebelisoa se nang le mapheo nakong ea ts'ebetso.
8) Lisebelisoa tsa ho itšeha tsa Carbide li tla ba lerootho le ho felloa ke matla ka lebaka la tšebeliso ea nako e telele.Ke kopa o se lumelle bao e seng litsebi ho ba leotsa.
9) Ka kopo boloka lisebelisoa tsa alloy tse tsofetseng le likhechana tsa lisebelisoa tsa alloy hantle ho thibela tšenyo ho ba bang.
