Inkqubo yokomba

01
Iimpawu zokomba
I-drill idla ngokuba neendawo ezimbini eziphambili zokusika, ezisikwa ngelixa i-drill ijika.I-rake ye-Angle ye-bit inkulu kwaye inkulu ukusuka kwi-axis esembindini ukuya kumda wangaphandle.Ukusondela kwisangqa sangaphandle, ukuphakama kwesantya se-bit.Isantya sokusika siyancipha ukuya kwiziko, kwaye isantya sokusika i-rotary center of bit is zero.Umnqamlezo we-drill ibekwe kufuphi ne-axis yeziko elijikelezayo, kunye necala le-rake ye-Angle yomnqamlezo inkulu, akukho ndawo yokunyamezela kwe-chip, kwaye isantya sokusika siphantsi, ngoko kuya kuvelisa ukuxhathisa okukhulu kwe-axial. .Ukuchasana nokusika kungancitshiswa kwaye umsebenzi wokusika unokuphuculwa kakhulu ukuba umgca wecala elinqamlekileyo uphonswe ngohlobo lwe-A okanye i-C kwi-DIN1414 kunye ne-cut cut kufuphi ne-central axis yi-Angle ye-rake e-positive.

Ngokwemilo yepiece workpiece, imathiriyeli, ulwakhiwo, umsebenzi, njl. njl., i-drill inokohlulwa ibe ziindidi ezininzi, ezifana ne-HSS drill (i-twist drill, i-drill yeqela, i-flat drill), i-carbide drill, i-indexable drill drill, umngxuma onzulu. , i-nesting drill kunye ne-adjustable head drill.

Ukuqhekeka kwetshiphu kunye nokususwa kwetshiphu
Ukusikwa kwe-bit kuqhutyelwa kumngxuma omxinwa, kwaye i-chip kufuneka ikhutshwe kwi-edge groove ye-bit, ngoko ke i-chip shape inempembelelo enkulu ekusebenzeni kokusika kwe-bit.Umzobo we-chip oqhelekileyo we-chip, i-tubular chip, itshiphu yenaliti, i-conical spiral chip, i-ribbon chip, i-fan chip, i-powder chip njalo njalo.
Xa imilo yetshiphu ingalunganga, ezi ngxaki zilandelayo ziya kwenzeka:

① Iitshiphusi ezicolekileyo zibhloka umphetho wegroove, zichaphazela ukuchaneka kokomba, zinciphisa ubomi bombhobho, kwaye zide zenze uqheliso (olufana neetshiphusi ezinjengomgubo, iitshiphusi zefeni, njl.);
② Iichips ezinde zijikeleze i-drill, zithintele ukusebenza, zibangele umonakalo kwi-drill okanye zithintele ulwelo lokusika emngxunyeni (ezifana ne-spiral chips, ribbon chips, njl.).

Indlela yokusombulula ingxaki yesimo se-chip esingafanelekanga:
① Inokusetyenziswa ngokwahlukeneyo okanye ngokudibeneyo ukunyusa isondlo, ukutya okwethutyana, i-edge yokusila, i-chip breaker kunye nezinye iindlela zokuphucula ukuphulwa kwe-chip kunye nesiphumo sokususa, ukuphelisa iingxaki ezibangelwa kukusika i-chip.
Uqheliso lobuchwephesha bokuqhekeza itshiphu lungasetyenziselwa ukomba.Ngokomzekelo, ukongeza i-chip breaker blade kwi-groove ye-bit iya kuqhekeza i-chip kwi-debris ekhutshwe ngokulula.I-Debris isuswe ngokucokisekileyo ecaleni komsele ngaphandle kokuvala umsele.Ke, i-chip breaker entsha inokufezekisa iziphumo zokusika ezigudileyo kuneebhithi zemveli.

Kwangaxeshanye, intsimbi emifutshane yentsimbi yenza ukuba ukupholisa kuqukuqelele kwincam ye-drill ngokulula, nto leyo ephucula ngakumbi isiphumo sokutshabalalisa ubushushu kunye nokusebenza kokusika kwinkqubo yomatshini.Kwaye ngenxa yokuba i-chip breaker entsha ihamba kuyo yonke i-groove ye-bit, igcina imilo yayo kunye nomsebenzi emva kokusila ngokuphindaphindiweyo.Ukongeza kolu phuculo olusebenzayo, kuyafaneleka ukukhankanya ukuba uyilo luphucula ukuqina komzimba we-drill kwaye kwandisa kakhulu inani lemingxuma egrunjiweyo phambi kwe-trim enye.

Ukuchaneka kokomba
Ukuchaneka komngxuma ubukhulu becala kuqulunqwe ubukhulu bokuvula, ukuchaneka kwendawo, ukubumbana, ukungqukuva, uburhabaxa bomphezulu kunye ne-orifice burr.
Izinto ezichaphazela ukuchaneka kwemingxuma egrunjiweyo ngexesha lokomba:

(1) Ukuchaneka kwe-Bit clamping kunye neemeko zokusika, ezifana nekliphu yokusika, isantya sokusika, ukutya, ukusika ulwelo, njl.;
② Ubungakanani besuntswana kunye nokumila, njengobude besuntswana, imilo yongqameko, ubume obungundoqo, njl.njl.;
(3) imilo yesixhobo sokusetyenzwa, esinje ngemilo yecala le-orifice, i-orifice shape, ubukhulu, i-clamping state, njl.
