Kuziva Kwekutanga kwePDC Cutter

PDC inomirira polycrystalline diamond compact. Muchidimbu, iyo PDC bhiti inoshandisa yakatenderera yedhaimani wafer yakasungirirwa kune carbide base seyo yekutanga kucheka michina. Dhaimondi rine polycrystalline-based uye rine mabhenefiti ekugara kwenguva refu pamwe nekurodza wega.

Synthetic diamond inodzivirira ka150 kupfuura carbide. Yakagadzirwa neGE, madhaimondi aya anowanzo kupihwa sechinhu chakagadzirwa-zhinji chakagadzirwa pasi petembiricha yakanyanya uye kumanikidzwa kugadzira mawafer edhaimani chaiwo.

Iyo leaching process inobvisa iyo cobalt catalyst kubva kuPDC microstructure. PDC diamond leaching inhanho yakakosha yekuita iyo inowedzera zvakanyanya hupenyu hurefu uye kuita kweiyo bit.

Iwo mawafer anobva abatanidzwa kune carbon base. Iyi carbide base inoshanda mabasa maviri. Chekutanga, ivo vanopa nzira yakasimba yekutsigira madhaimani wafers. Chechipiri, inopa nzira yekubatanidza dhaimondi kumuviri wechidiki sezvo usingakwanise kutengesa kana weld madhaimondi. Chinangwa ndechekupa ese ari maviri anocheka anocheka uku uchiwedzera mareti ekupinda.

Chikamu chedhaimani mu carbide substrate yePDC bit inonzi cutter. Iwo anouya muhukuru hutatu hwehupamhi 13mm, 16mm, uye 19 mm. PDC bit inonyanya kushandisa 1308 cutter.

Chimwe chinhu chakakosha chevacheki vedhaimondi ndeye chamfer, inova kona yemupendero wedhaimondi. Iyi kona ine kukosha kwakakosha pane dhizaini uye kuita. Hapana chamfer (zero madhigirii) cutters haawanzo shandiswa uye anongo shandiswa pavhu rakapfava sezvo ivo vanowanzo jaira kucheka. A 12-degree chamfer inokurumidza kupinda sarudzo. Ivo vachiri kuita chipping nyore. Zzbetter inogona kugadzira chamfer pane zvinodiwa nemutengi.

Iyo carbide base yakakosha pakuita kweanocheka. Macheki emhando yepamusoro anosungirirwa kumabhesi akakodzera ane magidhi chaiwo. Mabhesi emhando yakashata achaita kuti pave neurombo hwemhando yekucheka gungano.

Iyo carbide base yakakosha pakuita kweanocheka. Macheki emhando yepamusoro anosungirirwa kumabhesi akakodzera ane magidhi chaiwo, nepo mabhesi emhando yakashata achigadzira musangano wakashata wekucheka.

Yepamusoro-mhando PDC yakachengetedzwa zvakanaka uye inoshandiswa kana ichishandiswa munzvimbo dzakakodzera senge sandstone yakanyorwa kuti igare kwenguva yakareba.

Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe, kana kuti TUMUMA MAIL pazasi peji.
