Heano maitiro ekutora zvishoma zvichienderana nematatu akakosha mabhiti: zvinhu, coating uye geometric maficha.
01, maitiro ekusarudza zvinhu zve drill
Zvishandiso zvinogona kukamurwa kuita mhando nhatu: simbi yekumhanya, cobalt inomhanya simbi uye yakasimba carbide.
High speed Simbi (HSS):
Simbi yepamusoro-soro yakashandiswa sechishandiso chekucheka kweanopfuura zana kubva 1910. Ndiyo inonyanya kushandiswa uye yakachipa yekucheka chishandiso chiripo nhasi.High-speed simbi mabhiti anogona kushandiswa pazvibooreso zvemaoko uye munzvimbo dzakadzikama dzakadai semichina yekuchera.Chimwe chikonzero chekusimba kwesimbi inomhanya zvakanyanya chingava chekuti maturusi ayo, ayo anogona kuramba achirodzwa, akachipa zvekugona kushandiswa kwete chete sezvibhorani asiwo sematurusi ekutenderedza.
Cobalt high speed Steel (HSSE):
Cobalt-ine high speed simbi ine kuoma kuri nani uye kuomarara kwakatsvuka kupfuura simbi yekumhanya.Kuwedzera kwekuoma kunowedzerawo kuramba kupfeka, asi panguva imwe chete, kumwe kuoma kunobayirwa.Kufanana nesimbi yekumhanyisa, vanogona kukwenenzverwa kuti vavandudze kushandiswa kwavo.
CARBIDE:
Cemented carbide chinhu chakaumbwa chesimbi base.Pakati pavo, tungsten carbide inoshandiswa sematrix, uye zvimwe zvinhu zvezvimwe zvinhu zvinoshandiswa seanonamira kuburikidza neakatevedzana maitiro akaomarara senge inopisa isostatic yekutsikirira sintering.Mukuomarara, kuomarara kutsvuku, kupfeka kuramba uye zvimwe zvinhu zvichienzaniswa nesimbi yekumhanya, pane kuvandudzwa kukuru, asi mutengo wecarbide chishandiso zvakare unodhura kupfuura simbi yekumhanya.Cemented carbide muhupenyu hwechishandiso uye kumhanya kwekugadzirisa kupfuura zvakapfuura maturusi emidziyo ane zvimwe zvakanakira, mune inodzokororwa kugaya chishandiso, kudiwa kwehunyanzvi hwekukuya maturusi.
02, maitiro ekusarudza iyo bit coating
Iyo yekupfekedza inogona kukamurwa zvakaganhurwa kuva anotevera 5 marudzi zvichienderana nemhando yekushandiswa.
Asina kuvharwa: Maturusi ekucheka asina kuvharwa ndiwo akachipa, anowanzo shandiswa kugadzira aluminium alloy, yakaderera kabhoni simbi uye zvimwe zvinyoro zvinhu.
Black oxide coating: oxidation coating inogona kupa zvirinani pane isina kuvharwa chishandiso lubricity, ine nani oxidation kuramba uye kupisa kupisa, uye inogona kuvandudza pahupenyu hwesevhisi inopfuura 50%.
Titanium nitride coating: Titanium nitride ndiyo inonyanya kuvharidzira zvinhu, haina kukodzera kugadzirisa kuoma kwakanyanya uye yakakwirira yekugadzirisa tembiricha zvinhu.
Titanium carbon nitride coating: Titanium carbon nitride inogadzirwa kubva kune titanium nitride, ine yakakwirira tembiricha kuramba uye kupfeka kuramba, kazhinji yepepuru kana yebhuruu.Inoshandiswa muwekishopu yeHaas kugadzira simbi dzakakandwa.
Aluminium nitride titanium coating: kupfekedza aluminium nitride titanium kupfuura ese ari pamusoro anodzivirira tembiricha, saka anogona kushandisa pakakwirira kucheka mamiriro.Zvakadai sekugadzirisa superalloys.Inokodzerawo kugadzirwa kwesimbi uye simbi isina tsvina, asi nekuda kwekuti ine aluminium zvinhu, kemikari inogadziriswa ichaitika mukugadziriswa kwealuminium, saka zvakakosha kudzivisa kushandiswa kwezvinhu zvine aluminium.
Kazhinji, chibooreso checobalt chine titanium carbonitride kana titanium nitride coating ndiyo mhinduro ine hupfumi.
03. Geometric maitiro e drill bit
Zvimiro zveGeometric zvinogona kukamurwa kuita zvikamu zvitatu zvinotevera:
Kureba
Chiyero chehurefu kusvika kudhayamita chinonzi dhayamita kaviri, uye diki dhayamita, zviri nani kuoma.Kusarudza zvishoma nehurefu hwemupendero hwekubvisa chip uye hurefu hwakapfupika hwepamusoro hunogona kuvandudza kuoma kwekugadzira, nekudaro kuwedzera hupenyu hwematurusi.Hurefu husina kukwana hwemupendero hunogona kukanganisa chibhorani.
Drill tip Angle
The drill point Angle ye118° ingangove yakanyanya kuwanda mukugadzira uye inowanzo shandiswa simbi dzakapfava sesimbi yakapfava nealuminium.Iyi Angle dhizaini kazhinji haisi yekuzvimiririra, zvinoreva kuti gomba repakati rinofanirwa kugadzirwa kutanga.Iyo 135 ° drill tip Angle inowanzozvimiririra, iyo inochengetedza nguva yakawanda nekubvisa kudiwa kwekugadzirisa buri rimwe chete repakati.
Spiral Angle
A 30 ° spiral Angle isarudzo yakanaka kune zvakawanda zvekushandisa.Nekudaro, kune nharaunda uko kuchekwa kunobviswa zviri nani uye kucheka mipendero kwakasimba, zvishoma nediki spiral Angle inogona kusarudzwa.Kune zvinhu zvakaoma-ku-kushanda sesimbi isina tsvina, dhizaini ine hombe inotenderera Angle inogona kushandiswa kuendesa torque.
