Zvinhu zvinofanirwa kutariswa pakusarudza cemented carbide drill bits

Paunenge uchisarudza cemented carbide drills, iyo dimensional yechokwadi zvinodiwa zvekuchera zvinofanirwa kutariswa kutanga.Kazhinji, kana gomba racho richiva diki rinofanira kugadziriswa, rinoita kuti rive diki.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; mhando yeakadhindwa simende yecarbide drills kana inotsiviwa necemented carbide korona drills ndeye 0~0.07mm, iyo inonyanya kukodzera kugadzirwa kwegomba pamwe nekunyatso hunyanzvi zvinodiwa;madhiri ane simende carbide indexable ekuisa akakodzera kune inorema-basa rough machining Kunyangwe mutengo wayo wekugadzira unowanzo yakaderera pane mamwe marudzi ekudhirowa, kugadzirwa kwayo kwakadzikira, nekushivirira 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 yakakwirira machining kururama.Iyo cemented carbide indexable insert drill bit ine hurombo hwekugadzikana 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 padanho rekutanga rekugadzirisa, chibooreso chiri mumamiriro asina kugadzikana, izvo zvinogona kuita kuti muviri weku drill utendeuke, uye iyo yakareba iyo drill bit, inowedzera kuwanda kwekutsauka.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 and the replaceable cemented carbide korona drill bit inoumbwa maviri symmetrical cut edges ane self-centering geometric edge type.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 yakatemwa 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 iyo yakasimba carbide drill bit ikanyanya brittle, zviri nyore kutyora kana ichishandiswa pakugadzira lathe, kunyanya kana chibooreso chisina kunyatsodzika.Izvi ndezvechokwadi kunyanya dzimwe nguva.

Kubvisa chip idambudziko risingagoni kuregererwa mukuchera.Kutaura zvazviri, dambudziko rinowanzosangana 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 rakagadziriswa 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, pombi dzinotonhorera dzinofanirwa kushandiswa.Kudzika kwegomba rinofanira kugadziriswa, ndiko kunonyanya kuoma kubvisa machipisi uye kukura kunotonhorera kunodiwa kunodiwa.Naizvozvo, iyo shoma inotonhorera inoyerera inokurudzirwa nemugadziri wedhill inofanirwa kuve nechokwadi.Kana iyo inotonhorera inoyerera isina kukwana, chikafu chemuchina chinofanira kuderedzwa.
