Paunenge uchisarudza cemented carbide drills, iyo dimensional yechokwadi zvinodiwa zvekuchera zvinofanirwa kutariswa kutanga. Kazhinji kacho, kana gomba racho richiva diki rinofanirwa kugadziriswa, rinova diki rekushivirira. Naizvozvo, vagadziri vezvibooresa vanowanzoronga zvibhorani zvinoenderana nedhayamita yezita regomba riri kugadzirwa. Pakati pemhando ina dziri pamusoro dzakasimwa carbide drills, yakasimba simende carbide drills ane yakakwirira machining accuracy (kushivirira kwemhando ye φ10mm yakasimba simende ye carbide drills ndeye 0 ~ 0.03mm), saka isarudzo iri nani yekugadzira maburi akanyanya-chaiyo; madhiri akaiswa simende e carbide drills kana inotsiviwa necemented carbide korona drills ndeye 0～0.07mm, iyo inonyatsokodzera kugadzirwa kwegomba pamwe neakawanda echokwadi zvinodiwa; madhiri ane simende anoiswa carbide indexable anonyanya kukodzera kune inorema-basa rough machining Kunyangwe mutengo wayo wekugadzira unowanzo yakaderera pane mamwe marudzi ekudhirowa, magadzirirwo ayo zvakare akadzikira, aine kushivirira kwakasiyana 0～0.3mm (zvinoenderana nehurefu dhiyabhorosi reshiyo yekuchera), saka inowanzo shandiswa kugadzira gomba nekudzika kwakadzika, Kana kupedzisa kupedzisa kwegomba nekutsiva blade inofinha.
Kugadzikana kweiyo drill bit pachayo kunofanirawo kutariswa. Semuenzaniso, yakasimba carbide drills yakanyanya kuomarara, saka vanogona kuwana yakakwira machining kururama. Iyo simende carbide indexable inopinza drill bit ine hurombo kugadzikana kwechimiro uye inogara ichitsauka. Mabhii maviri ane indexable akaiswa pane iyi drill bit. Kupinza kwemukati kunoshandiswa kuchina chikamu chepakati chegomba, uye chinopinza chekunze chinoshandiswa kugadzira mupendero wekunze kubva pamukati kusvika padhayamita rekunze. Sezvo chete blade yemukati inopinda mukucheka panguva yekutanga yekugadzirisa, chibooreso chiri mumamiriro asina kugadzikana, izvo zvinogona kuita kuti muviri wekuchera utsauke, uye iyo yakareba iyo drill bit, iyo yakawanda yakawanda yekutsauka. Naizvozvo, kana uchishandisa simende carbide indexable dhiraivha ine kureba inopfuura 4D yekuchera, chikafu chinofanirwa kuderedzwa zvakafanira pakutanga kwechikamu chekuchera, uye chiyero chekudya chinofanira kuwedzerwa kusvika pachiyero chakajairwa mushure mekupinda mukucheka kwakagadzikana. phase .
The welded cemented carbide drill bit uye inotsiviwa simende carbide drill bit inoumbwa maviri symmetrical yekucheka micheto ine self-centering geometric edge mhando. Iyi yakakwirira-yakadzikama yekucheka kumucheto dhizaini inoita kuti zvisave zvakakosha kana uchicheka mukati meiyo workpiece Deredza chiyero chekudya, kunze kwekunge iyo drill inoiswa oblique uye inocheka mune imwe kona kumusoro kweiyo workpiece. Panguva ino, zvinokurudzirwa kuderedza chiyero chekudya ne30% kusvika 50% pakuchera mukati nekubuda. Nekuti simbi yekubooresa muviri werudzi urwu rwechibooreso chinogona kuburitsa diki deformation, yakanyatsokodzera kugadzirwa kwelathe; nepo solid carbide drill drill bit is more brittle, zviri nyore kutyoka kana ichishandiswa pakugadzira lathe, kunyanya kana chibooreso chisina kunyatsodzika. Izvi ndezvechokwadi kunyanya dzimwe nguva.
Kubvisa chip idambudziko risingagoni kuregererwa mukuchera. Kutaura zvazviri, dambudziko rinowanzoitika mukuchera nderokushaya chip kubviswa (kunyanya kana machining low-carbon steel workpieces), uye dambudziko iri harigoni kudziviswa pasinei nokuti chibooreso chinoshandiswa sei. Mashopu ekugadziridza anowanzo shandisa jekiseni rekunze rinotonhorera kubatsira kubvisa chip, asi nzira iyi inoshanda chete kana kudzika kwegomba rakagadziridzwa kuri kudiki pane dhayamita yegomba uye maparamita ekucheka akaderedzwa. Pamusoro pezvo, mhando yakakodzera yekutonhodza, mwero wekuyerera uye kudzvanywa kunofanirwa kusarudzwa kuti ienderane nedhayamita yechibhorani. Kune maturusi emuchina asina kutonhora sisitimu mu spindle, mapaipi anotonhodza anofanirwa kushandiswa. Kudzika kwegomba rinofanira kugadziriswa, ndiko kunonyanya kuoma kubvisa machipisi uye kuwedzera kutonhora kunodiwa kunodiwa. Naizvozvo, iyo shoma inotonhorera inoyerera inokurudzirwa nemugadziri wedhill inofanirwa kuve nechokwadi. Kana iyo inotonhorera inoyerera isina kukwana, chikafu chemuchina chinofanira kuderedzwa.
