Iyo Kugadzira Maitiro eTungsten Carbide Kukuya Quills: Kubva Paupfu kuenda kune Precision Tool.

Tungsten carbide kukuya quill maturusi akakosha mumunda wekukuya-chaiyo, uye kuita kwavo kwakasarudzika kunobva mukunaka kwekugadzira maitiro. Rwendo kubva kumicron-level poda kuenda kune chaiyo chishandiso chinosanganisira nhevedzano yehungwaru inodzorwa Maitiro.

Raw Material Proportioning uye Kusanganisa

Kugadzira kunotanga nekunyatsosarudzwa tungsten carbide poda uye cobalt poda. Cobalt inoshanda sechikamu chekusunga, uye zvirimo zvinokanganisa zvakananga kuoma kwechigadzirwa chekupedzisira uye kuoma. Kazhinji, iyo cobalt yemukati inotangira pa6% kusvika 12%, yakanyatso kuenzaniswa zvinoenderana nezvinodiwa zvekushandisa. Aya mamicron-level powders akanyorova-akasanganiswa mumabhora ezvigayo kuti ave nechokwadi chekugovera mayunifomu emamolecular-level.

Kugadzira Maitiro

Iyo yakasanganiswa slurry inopfapfaidzwa-yakaomeswa mune yakasununguka-inoyerera granules. Zvadaro, chaiyo inotonhora isostatic yekutsikirira tekinoroji inoshandiswa kumanikidza zvinhu pa200-300 MPa kudzvanywa. Panguva ino, iyo yekutanga geometric chimiro che carbide grinding shaft inoumbwa, asi simba rinoramba rakaderera, richida kumwe kugadziridzwa.

Sintering Process

Sintering ndiyo yakakosha nzira yekugadzira. Mumavira ekupisa, tembiricha inodzorwa zvakanaka pamusoro penzvimbo yekunyungudika yecobalt (kazhinji 1400-1500 ° C). Munguva iyi, chikamu checobalt chinonyunguduka uye chinonyorovesa tungsten carbide zvimedu, zvichigadzira dense metallurgical bond kuburikidza nechikamu chemvura sintering. Kunyatso kudzora kwekudziya curve uye kubata nguva kwakakosha kuti uve nechokwadi chekuzara uye kudzora kukura kwezviyo.

Precision Machining

Iyo sintered isina blank carbide grinding bar inopinda iyo chaiyo machining nhanho, iyo yakakosha pakuona kuti quill yekukuya inosangana nezvinodiwa zvekushandisa. Benchmark machining inotanga kuitwa uchishandisa ekupedzisira-chaiyo cylindrical grinders ane madhaimani ekukuya mavhiri kumisikidza chaiyo referensi axis, ine dimensional kushivirira kunodzorwa mukati me ± 0.01 mm.

Makiyi chaiwo ekukuya maitiro anosanganisira:

1. Tool shank processing: Kushandisa high precision grinders nemavhiri edhaimondi, zvinosanganisira kukuya rough, semi-finishing, uye kupedza. Kukuya kwakashata kunobvisa zvinhu zvakawandisa, kupera kwehafu kunozadzisa zvinodiwa, uye kupedzisa kunovimbisa kushata kwepamusoro Ra ≤ 0.2 μm. Taper angle tolerances yeHSK, CAPTO, uye mamwe mainterface anofanira kunge ari mukati me ± 30”.

2. Inotonhorera kugadzirisa gomba: Kushandisa gomba rakadzika midziyo yekuchera nepfuti yekuchera teknolojia. Kuve nechokwadi chemhando yemadziro egomba, kukurumidza kwekudya (kazhinji 50-100 mm/min) uye inotonhorera kudzvanywa (10-15 MPa) inofanira kunyatsodzorwa. Gomba dhayamita kurongeka kunofanirwa kusvika kugiredhi reH7, nekutadza kwekutwasuka kusingadarike 0.02/100 mm.

3. Dynamic balancing: Kushandisa hunyanzvi hwekuyeresa michina kugadzirisa kuparadzirwa kwehuwandu nekubvisa zvinhu zvine symmetrically. Zvinodiwa zvinosanganisira kuwana G2.5 chiyero chegiredhi nekusarira unbalance isingasviki 1 g·mm/kg pahupamhi hwekushanda.

Quality Inspection

Kuongorora kwekupedzisira kunosanganisira kurongedza michina yekuyeresa yejometri dimensions, laser interferometers yefomu uye chinzvimbo kushivirira, michina yekuenzanisa yekuyedza chiyero chesimba, uye simbi microscopes yekuongorora zvinhu. Zvigadzirwa chete zvinopfuura bvunzo dzakaomesesa ndizvo zvinounzwa.

Iyo yese yekugadzira maitiro inobatanidza akawanda matekinoroji anosanganisira hupfu simbi, chaiyo machining, uye kupisa kurapwa. Kudzora kwakaringana padanho rega rega pamwe chete kunopa kune yakasarudzika kuita kwetungsten carbide kukuya quill. Kunyanya muchikamu chekugadzira machining, kushandiswa kwakazara kweiyo yekupedzisira-yakaoma chishandiso tekinoroji, chaiyo yekuyera tekinoroji, uye otomatiki kutonga tekinoroji inovimbisa micron-level yekugadzira chaiyo.

Zhuzhou Zvirinani Tungsten Carbide Kambani inogona kupa mhando yepamusoro, kunyatsoita tungsten carbide grind quills. Mirira kuonana kwako.
