Wahisemo Bitike Kuburyo bwa CNC yo gucukura no gusya

Ubwoko bwimyitozo ishobora gukoreshwa kuriImashini zo gucukura no gusya CNCshyiramo imyitozo ya twist, U imyitozo, imyitozo yubukazi, hamwe nimyitozo yibanze.

Imyitozo ya Twist ikoreshwa cyane mumashini imwe yimyitozo yo gucukura kugirango yorohereze imbaho ​​imwe yoroshye. Ubu ntibakunze kugaragara mubakora ibizunguruka binini byumuzunguruko, kandi ubujyakuzimu bwabo burashobora kugera ku nshuro 10 z'umurambararo.

Iyo substrate stack itari hejuru, gukoresha amaboko ya drill birashobora kwirinda gutandukana. UwitekaImashini yo gucukura CNCikoresha sima ya karbide yashizwemo shank imyitozo, irangwa nubushobozi bwo guhita busimbuza imyitozo. Umwanya uhagaze neza, nta mpamvu yo gukoresha amaboko ya drill. Inguni nini ya helix, umuvuduko wo gukuraho chip byihuse, bikwiriye gukata byihuse. Muburebure bwuzuye bwimyironge ya chip, diameter ya myitozo ni cone ihindagurika, kandi guterana hamwe nurukuta rwumwobo mugihe cyo gucukura ni bito, kandi ubwiza bwo gucukura buri hejuru. Ibipimo bisanzwe bya drill shank ni 3.00mm na 3.175mm.

Imyitozo ya bito yo gucukura amabati muri rusange ikoresha karbide ya sima, kubera ko ikirahuri cya epoxy ikirahuri cyometseho icyuma cyumuringa cyambara igikoresho vuba. Ibyo bita karbide ya sima ikozwe mu ifu ya tungsten karbide nka matrix na poro ya cobalt nkumuhuza binyuze mukibazo no gucumura. Ubusanzwe irimo karbide ya tungsten 94% na cobalt 6%. Kubera ubukana bwayo bwinshi, irwanya kwambara cyane, ifite imbaraga runaka, kandi ikwiriye gukata vuba.

Gukomera gukabije kandi byoroshye. Mu rwego rwo kunoza imikorere ya karbide ya sima, bamwe bakoresha urwego rwa microne 5-7 ya karbide ya titanium ikomeye cyane (TIC) cyangwa nitride ya titanium (TIN) kuri karbide substrate hamwe nubumara bwimyuka mvaruganda kugirango ikomere cyane. Bamwe bakoresha tekinoroji yo gutera ion kugirango bate titanium, azote, na karubone muri matrike kugeza mubwimbitse runaka, ibyo ntibitezimbere ubukana n'imbaraga gusa, ariko kandi nibi bice byatewe bishobora kwimuka imbere mugihe bito bitangiye. Bamwe bakoresha uburyo bwumubiri kugirango bagire urwego rwa firime ya diyama hejuru yabito bito, itezimbere cyane ubukana no kwambara birwanya imyitozo ya biti. Ubukomezi nimbaraga za karbide ya sima ntabwo bifitanye isano gusa nigipimo cya karubide ya tungsten na cobalt, ahubwo bifitanye isano nuduce twa poro.

Kubice bya ultra-nziza ya sima ya karbide ya dring bits, impuzandengo yubunini bwa tungsten karbide icyiciro kiri munsi ya micron 1. Ubu bwoko bwimyitozo ntabwo ifite ubukana buke gusa ahubwo bwanatezimbere imbaraga zo kwikuramo no guhindagurika. Kugirango uzigame ibiciro, bits nyinshi za drill ubu zikoresha imiterere ya shank. Umwitozo wumwimerere bito bikozwe muburyo bukomeye muri rusange. Noneho drill shank yinyuma ikozwe mubyuma bidafite ingese, bigabanya cyane igiciro. Ariko, kubera gukoresha ibikoresho bitandukanye, imbaraga za concentration ntabwo ari nziza nkibikomeye muri rusange. Alloy drill bits, cyane cyane kuri diametre nto.
