CBN na PCD: Intambara yo gukata ibikoresho bya superhard - Kwibira cyane mubikorwa no mubikorwa
CBN (Cubic Boron Nitride) Ibikoresho byo gutema CNC
CBN, cyangwa Cubic Boron Nitride, ni ibikoresho byubukorikori bizwiho ubukana bukabije kandi biramba. Nibya kabiri nyuma ya diyama mubijyanye no gukomera, bigatuma iba ibikoresho byiza byo gukata ibikoresho bikoreshwa mugukora cyane. Ibikoresho byo gukata CBN mubisanzwe bikoreshwa mugutunganya ibyuma bikomeye, ibyuma bikozwe mucyuma, nibindi bikoresho bikomeye cyane bigoye gutunganya hamwe nibikoresho bisanzwe byo gutema.
Uburyo bwo Gukora Ibikoresho bya CBN:
Umusaruro wibikoresho byo gukata CBN mubisanzwe birimo synthesis ya boron nitride (BN) munsi yumuvuduko mwinshi nubushyuhe bwinshi. Inzira itangirana nifu ya boron na gaze ya azote, ikorerwa mubihe bikabije (hejuru ya 1500 ° C) kugirango ikore kristu ya boron nitride (c-BN). Izi kristu noneho zahujwe nibikoresho bya matrix, akenshi bober ya cobalt, kugirango ikore igikoresho cyangwa igikoresho. Ihuriro ritanga igikoresho cya CBN hamwe nubukomezi bwacyo budasanzwe no kwambara birwanya.
Kwinjiza CBN birashobora gukorwa muburyo butandukanye no mubunini, bitewe nibisabwa byihariye byo gutunganya. Igikoresho cyanyuma gikunze gucumurwa, hasi, no gutwikirwa kugirango turusheho kunoza imikorere no kurangiza. Ubushobozi bwigikoresho cyo kugumya gukata cyane ku bushyuhe bwo hejuru butuma ihitamo ryiza kubikorwa biremereye cyane mu nganda nko mu kirere, mu modoka, no gukora ibikoresho.
PCD (Polycrystalline Diamond) Ibikoresho byo gutema CNC
PCD, cyangwa Polycrystalline Diamond, ni ibikoresho bikozwe muguhuza kristu nziza ya diyama munsi yumuvuduko mwinshi nubushyuhe, bikavamo ibikoresho bikomeye, biramba byo gukata. Ibikoresho bya PCD bizwiho kwihanganira kwambara bidasanzwe, cyane cyane iyo gutunganya ibyuma bidafite fer nka aluminium, umuringa, n'umuringa, hamwe n'ibikoresho byinshi.
Uburyo bwo Gukora Ibikoresho bya PCD:
Umusaruro wibikoresho bya PCD utangirana no gukora ifu nziza ya diyama, ivangwa nicyuma gihuza ibyuma, mubisanzwe cobalt cyangwa ifu yicyuma. Uru ruvange noneho rukorerwa ubushyuhe bwo hejuru, umuvuduko mwinshi uzwi nka "gucumura" mubinyamakuru bidasanzwe. Muri iki gikorwa, kristu ya diyama irahurira hamwe, igakora imiterere yuzuye, polycristaline.
Ibikoresho bya PCD mubusanzwe bikorwa muburyo bubiri: monolithic na brazed. Muburyo bwa monolithic, igikoresho cyose gikozwe muri PCD, mugihe muburyo bwa brazed, urwego ruto rwa PCD rwometse kuri karbide substrate. Nyuma yo gucumura, ibikoresho bya PCD biri hasi kandi bisizwe neza kugirango bipime neza, byemeza gukata gukabije no kurangiza neza. Bashobora gukomeza kuvurwa hamwe kugirango bongere imbaraga zo kwambara no okiside, bishobora kunoza imikorere yabo mubikorwa byihariye.
Ibikoresho bya PCD bikoreshwa cyane mubikorwa byo guca ibintu neza kandi bifasha cyane cyane gutunganya ibikoresho bitera kwambara cyane kubikoresho gakondo. Bitewe nubukomere budasanzwe hamwe nubushobozi buke bwo guterana, batanga imikorere idasanzwe haba kurangiza no kwihuta cyane.
Kugereranya hagati ya CBN na PCD ibikoresho byo gutema

Itandukaniro ry'ingenzi:
Guhuza Ibikoresho:
CBN ikwiranye cyane nibikoresho bikomeye kandi byangiza nkibyuma bikomeye hamwe nicyuma.
PCD nibyiza kubikoresho byoroshye nka aluminium, umuringa, hamwe nibigize, bikunda kwambara ibikoresho gakondo vuba.
Imikorere ku bushyuhe bwo hejuru:
Ibikoresho bya CBN birashobora kwihanganira ubushyuhe bwo hejuru bitagabanije, bigatuma bikora neza mumashanyarazi menshi kandi ashyushye cyane.
Ibikoresho bya PCD, nubwo bikomeye cyane, ntibihanganira ubushyuhe bwo hejuru cyane kandi birashobora gutakaza inkombe mubihe nkibi.
Ibiciro:
Ibikoresho bya CBN bikunda kuba bihendutse kuruta ibikoresho bya PCD, kuko PCD isaba uburyo bukomeye bwo gukora kandi ibikoresho fatizo ubwabyo bihenze.
Ubuso Kurangiza no Gusobanura:
Ibikoresho bya PCD birakwiriye cyane kugirango ugere kuri ultra-nziza yubuso burangije, cyane cyane mubikoresho bidafite ferrous.
Ibikoresho bya CBN, nubwo bisobanutse neza, birenze cyane kuramba no guca ubukana aho kugera kurwego rwo hejuru kurangiza mubikoresho byoroshye.
Byombi CBN na PCD CNC ibikoresho byo gukata bitanga imikorere idasanzwe, ariko bihuza ibikenerwa bitandukanye. Ibikoresho bya CBN nibyiza kubikoresho bikomeye, ibikoresho bikomeye hamwe nubushyuhe bwo hejuru, mugihe ibikoresho bya PCD bimurika mugihe ukorana nibyuma byoroheje nibikoresho byinshi, bitanga ubuzima burebure hamwe nibikorwa byiza byo guca. Guhitamo byombi biterwa nibikoresho byihariye birimo gutunganywa, ubuzima bukenewe bwibikoresho, hamwe nibidukikije.
