Kudhirowa ndiyo nzira yakajairika yekugadzirisa mukugadzirwa. Kana uchitenga mabhedhi ekudhirowa, Drill Bits inouya mune dzakasiyana zvinhu uye mavara akasiyana. Saka mavara akasiyana ekurova mabhedhi anobatsira sei? Ko ruvara rune chero chinhu chekuita nekukweva kubhururuka mhando? Ndeupi ruvara ruvara zvishoma zviri nani kutenga?
Chekutanga pane zvese, isu tinofanirwa kujekesa kuti kunaka kwekurova kusingakwanise kutongwa chete nerudzi rwayo. Iko hakuna hukama hwakananga uye husingadzivisike pakati pemavara uye mhando. Iwo akasiyana mavara ekukweva mabheti anonyanya kukonzerwa nehunyanzvi hwekugadzirisa maitiro. Ehe, tinogona kuita kuti mutongo wakaomesesa kubva pane ruvara, asi nhasi madiki-emhando yekukweva mabheti anogadzirisawo mavara avo kuti awane kutaridzika kwemhando yepamusoro.
Saka ndedzipi misiyano pakati pekurovera mabheti emavara akasiyana?
Yakakwira-mhando zvizere pasi yakakwirira-yekumhanyisa simbi yekukweva mabheti anowanzowanikwa muchena. Ehe, iyo yakakandwa yekudhirowa zvishoma inogona zvakare kucheneswa nekukuya kugeda denderedzwa rekunze. Chii chinoita kuti vasike mhando haisi chete zvinhu pachavo, asi zvakare kutonga kwemhando panguva yekukuya. Izvo zvakanyanyisa uye hakuzove nekupisa pane zvekushandisa. Vatema vane nitride drill mabheti. Iyo nzira yemakemikari inoisa chishandiso chakapera mumusanganiswa weAmmonia uye mvura yemvura uye inoita kupisa kupisa kwekuchengetedza pa540 ~ 560c ° kuvandudza kusimba kwechishandiso. Vazhinji vevatema vakadhirowa parizvino vari pamusika chete mutema chete muvara (kuitira kuti vafukidze kupisa kana ganda dema pamusoro pechishandiso), asi iyo chaiyo yekushandisa haina kuvandudzwa zvakabudirira.
Kune matatu matanho ekugadzira mabhedhi ekudonha. Kutema kusviba ndiko kwakanyanya. Vachive vachena vane yakajeka uye yakapurirwa mapeji. Sezvo kukwira-tembiricha olidation hakudiwi, chimiro chetsiva chesimbi hachizoshandiswe, chinogona kushandiswa pakuchera mabasa zvine hungwaru zvishoma. Yero-brown drill mabheti ane cobalt, iyo isingatauriki mutemo mukukweva kwedutu indasitiri. Cobalt-ine madhaimani anobva anobva zvachena, asi anozobatwa mune yero-brown (inowanzozivikanwa se amber). Ndedzipi dzimwe dzakanakisa dziri kutenderera. M35 (Co 5%) zvakare ine ruvara rwegoridhe runonzi Titanium-yakarongedzwa kudhiraira zvishoma, iyo yakakamurwa mukushongedza kubhururuka uye maindasitiri ekubatanidza. Iyo yekushongedza yekushongedza haina kunaka, inotaridzika zvakanaka. Mhedzisiro yekumagadzirwa maElectrolating yakanyanya kunaka. Iko kuomarara kunogona kusvika kuHRC78, iyo yakakwira kupfuura kuomarara kweCobalt Drill (HRC54 °).
Maitiro ekusarudza kudhiraivha
Sezvo ruvara harisi iyo nzira yekutonga mhando yekurova zvishoma, maitiro ekusarudza kudhira?
Kubva pane zvakaitika, kazhinji kutaura, kuchena kuchena mabheji kazhinji kwakazara pasi rakanyanya-kumhanya simbi yekukwevera mabheti uye inofanirwa kuve nemhando yepamusoro. Goridhe ine Titanium nitride ichivharira uye kazhinji kazhinji ingave yakanyanya kunaka kana yakaipa uye inogona kunyengedza vanhu. Hunhu hwekutakura hunosiyanawo. Vamwe vanoshandisa yakaderera-mhando carbon chishandiso simbi, iri nyore kune anneal uye ngura, saka inoda kusvibiswa.
Kune makatekark uye madhiri ekushongedza madhiri pane iyo shank yekukwevera zvishoma, inowanzojeka, uye mhando yeLaser uye Electro-etching haifanirwe kunge zvakanyanyisa. Kana mavara akaumbwa aine convex edges, zvinoratidza kuti kudhonzwa kwekurova kwehunhu husina kunaka, nekuti iyo convex rondedzero yevatambi inokonzeresa kureruka kutadza kuita zvinodiwa kuti uite zvinodiwa. Iyo pamucheto weshoko rakabatanidzwa zvakanaka kune cylindrical pamusoro peiyo basa rekushanda, uye kudhiraivha zvishoma nemucheto wakajeka weshoko ndekwemhando yakanaka. Iwe unofanirwa kutarisa kudhiraira zvishoma nemucheto wakanaka wekucheka pamucheto. Zvizere zvizere zvinodhaka zvine mwero wakanaka wekucheka uye wosangana nezvinodiwa zveHelix nzvimbo, nepo madhiri emhando yemhando isina kunaka ane nzvimbo isina kunaka.
