Kuchera inzira yakajairika yekugadzirisa mukugadzira.Paunenge uchitenga zvibooreso, zvibooreso zvinouya muzvinhu zvakasiyana uye mavara akasiyana.Saka mavara akasiyana ezvibooro anobatsira sei?Ko ruvara rune chekuita nedrill bit quality?Ndeupi ruvara drill bit zviri nani kutenga?
Chokutanga pane zvose, tinofanira kujekesa kuti kunaka kwechibhorani hakugoni kutongwa chete nemuvara wayo.Hapana hukama hwakananga uye husingadzivisiki pakati pevara uye hutano.Iwo mavara akasiyana-siyana eku drill bits anonyanya kukonzerwa nemaitiro akasiyana ekugadzirisa.Zvamazvirokwazvo, tinogona kuita mutongo wakakasharara unobva paruvara, asi madhiri emazuva ano emhando yakaderera anozogadzirisawo mavara awo kuti awane kutaridzika kwemhando yepamusoro-soro.
Saka ndeupi mutsauko pakati pezviboorero zvemavara akasiyana?
Mabhiti ekubooresa simbi emhando yepamusoro akazara anowanikwa ari machena.Ehe, chibooreso chakakungurutswa chinogona zvakare kucheneswa nekukuya zvakanaka denderedzwa rekunze.Chii chinoita kuti vave nehupamhi hwepamusoro haisi iyo chete zvinhu zvayo, asiwo kutonga kwehutano panguva yekukuya.Iyo yakanyanya kuomarara uye hapazove nekutsva pane mudziyo wekushandisa.Iwo matema ndeeNitride drill bits.Ikemikari nzira inoisa chigadziro chakapedzwa mumusanganiswa weammonia nemhepo yemvura uye inoita kurapa kwekuchengetedza kupisa pa 540 ~ 560C ° kuvandudza kusimba kwechigadzirwa.Mazhinji ezvibooreso zvitema pari zvino pamusika anongori dema muruvara (kuitira kuvhara kutsva kana ganda dema pamusoro pechishandiso), asi iyo chaiyo yekushandisa maitiro haina kunyatsogadziriswa.
Pane 3 maitiro ekugadzira zvibooreso.Black rolling ndiyo yakaipisisa.Iwo machena ane mipendero yakajeka uye yakakwenenzverwa.Sezvo high-temperature oxidation isingadiwi, chimiro chezviyo chesimbi hachizoparadzwi, chinogona kushandiswa pakuchera workpieces nekuoma zvishoma.Yellow-brown drill bits ine cobalt, inova mutemo usingataurike muindasitiri yekuchera.Cobalt-ine madhaimondi akatanga chena, asi anozoitwa atomi kuita yero-brown (inowanzozivikanwa seamber).Ndiwo mamwe akanakisa ari kutenderera parizvino.M35 (Co 5%) zvakare ine ruvara rwegoridhe runodaidzwa kuti titanium-plated drill bit, iyo yakakamurwa kuita yekushongedza yekushongedza uye yekupfeka maindasitiri.Iyo yekushongedza plating haina kunaka, inongotaridzika yakanaka.Mhedzisiro yeindasitiri electroplating yakanaka kwazvo.Iko kuoma kunogona kusvika HRC78, iyo yakakwirira kudarika kuoma kwecobalt drill (HRC54 °).
Nzira yekusarudza chibooreso
Sezvo ruvara rusiri mucherechedzo wekutonga kunaka kwechibhorani, ungasarudza sei dhiri?
Kubva pane zvakaitika, kazhinji kutaura, zvibooreso zvichena zvinowanzogadzika zvakazara pasi-yepamusoro-kumhanya mabhiti ekubooresa uye anofanirwa kuve nemhando yepamusoro.Iyo yegoridhe ine titanium nitride coating uye inowanzove yakanyanya kunaka kana yakaipisisa uye inogona kunyengedza vanhu.Hunhu hwekusviba hunosiyanawo.Vamwe vanoshandisa simbi yemhando yakaderera kabhoni, iyo iri nyore kuvharisa uye kuita ngura, saka inoda kusviba.
Iko kune chiratidzo chekutengesa uye dhayamita kushivirira mamaki pane shank ye drill bit, iyo inowanzojeka, uye mhando yelaser uye electro-etching haifanirwe kunge yakanyanya kushata.Kana mavara akaumbwa aine mipendero ye convex, zvinoratidza kuti chibhorani hachina kunaka, nekuti iyo convex yeratidziro yemavara inozoita kuti chibooreso che clamping iko kutadza kuzadzisa zvinodiwa.Mucheto weshoko wakanyatsobatanidzwa kune cylindrical surface ye workpiece, uye drill bit nemucheto wakajeka wezwi ndeyehutano hwakanaka.Iwe unofanirwa kutsvaga chibooreso chine yakanaka yekucheka mupendero pamuromo.Zvibooreso zvepasi zvakazara zvine mipendero yakanaka kwazvo yekucheka uye zvinosangana nezvinodiwa zvenzvimbo dzehelix, nepo zviboorero zvisina kunaka zvine nzvimbo dzisina kunaka.
