Pane here hukama pakati pechibhorani ruvara uye kunaka

Chokutanga pane zvose: hazvibviri kusiyanisa hutano hwechibooreso kubva kune ruvara. Hapana hukama hwakananga uye husingadzivisiki pakati pemuvara uye hutano. Iwo akasiyana mavara ekudhiraivha mabheti anonyanya kusiyana mukugadzira tekinoroji. Ehe, iwe unogona kuita mutongo wakakasharara kubva paruvara, asi yazvino yehurombo yemhando yekubooresa Ichagadzirisa iwo mavara ega kuti iwane kutaridzika kwemhando yepamusoro yekubooresa.

Ndeupi musiyano pakati pemadhiri emavara akasiyana

Yepamusoro-soro yakazara-yakagayiwa yakakwirira-kumhanya simbi yekubooresa inowanzoonekwa mune chena. Zvamazvirokwazvo, zvibooreso zvakakungurutswa zvinogona zvakare kucheneswa nekukuya kwakanaka kwedenderedzwa rekunze. Chikonzero chemhando yepamusoro ndechekuti mukuwedzera kune iyo pachayo, iyo yemhando yekudzora panguva yekugaya zvakare Yakanyanya kuomarara, hapana kutsva pamusoro pechishandiso. Dema chibooreso che nitrided. Iyo ikemikari nzira yekuvandudza kusimba kwechishandiso nekuisa chigadziro chakapedzwa mumusanganiswa weammonia uye mhute yemvura uye nekuzviisa pasi pekupisa kwe540-560C °.

Parizvino, madhiri akawanda evatema pamusika anongori dema (kuitira kuvhara kupisa kana ganda dema pamusoro pechishandiso), asi iyo chaiyo yekushandisa mhedzisiro haina kunyatso kuvandudzwa.

Pane nzira nhatu dzekugadzira drill bits. Dema rakakungurutswa, rakaipisisa.Iwo machena anochekwa uye anokwenenzverwa. Kusiyana nekukunguruka, iyo isingaburitse tembiricha oxidation, chimiro chezviyo chesimbi hachina kukuvadzwa, uye chinoshandiswa kudhiza zvishoma zvakakwirira kuomarara workpieces. Iyo tan drill bit inodaidzwa kuti cobalt-containing drill muindasitiri. Uyu ndiwo mutemo wakavanzika weindastiri yekuchera.

Cobalt-ine madhaimani pakutanga aive machena uye achigadzirwa nekukuya. Payakazoitwa atomu, yakaitwa yero-brown (inowanzonzi amber), iyo ndiyo inonyanya kushandiswa kutenderera panguva ino. M35 (Co 5%) zvakare ine goridhe-ruvara. Rudzi urwu rwechibooreso rwunodaidzwa kuti titanium-plated drill, iyo yakakamurwa kuita yekushongedza yekushongedza uye plating yeindasitiri. Iyo yekushongedza plating haina mhedzisiro zvachose, yakanaka uye yegoridhe. Industrial plating yakanaka kwazvo, kuomarara kunogona kusvika HRC78, iyo yakakwira kupfuura iyo yemadhaimondi ane cobalt (HRC54 °).

Sezvo ruvara rusiri mucherechedzo wekutonga kunaka kwechibhorani, unotenga sei chibooreso?

Tichitarisa kubva pane zvakaitika, kazhinji, chena inowanzogadzirwa ne-high-speed steel drill bit, unhu hunofanira kunge huri hwakanakisisa. Iwo egoridhe titanium nitride akaputirwa uye kazhinji anove akanakisa kana asina kunyengedzwa. Hunhu hwevatema zvakare hauna kuenzana. Mamwe akagadzirwa nesimbi isina kunaka kabhoni, iyo iri nyore kunyura uye iri nyore kuita ngura, saka inoda kusviba.

Kazhinji, kana iwe uchitenga chibooreso, unogona kuona chiratidzo chekutengesa pane dhiri shank uye dhayamita kushivirira chiratidzo. Chiratidzo chakajeka, uye mhando yelaser kana corrosion yemagetsi haina kunyanya kushata. Kana chiri chimiro chakamisikidzwa, kana mupendero wechimiro uchiputika, kunaka kwechibooreso kwakashata, nekuti contour yehunhu hwakaputika huchaita kuti kurongeka kwechibhorani kuve kushoma pane zvinodiwa, uye mupendero wehunhu. yakajeka, yakanaka kwazvo uye cylindrical pamusoro pechibhorani shank Junctions ndeyemhando yakanaka. Mukuwedzera, zvinoenderana nekucheka kwechidimbu chekuchera. Mucheto we-full-grind drill yakanaka kwazvo, spiral surface inosangana nezvinodiwa, uye hurombo huri hurombo huri kumashure kwekona.
