Enqubweni yesimanje yomshini nokukhiqiza, kuvame ukuba nzima ukucubungula nokukhiqiza ngamathuluzi ajwayelekile ajwayelekile, okudinga amathuluzi angajwayelekile enziwe ngokwezifiso ukuze aqedele umsebenzi wokusika. Amathuluzi we-Tungsten steel non-standard, okungukuthi, amathuluzi anomumo okhethekile we-carbide engasindisiwe, ngokuvamile angamathuluzi enziwe ngokwezifiso ngokuya ngezidingo zemidwebo nokusebenza kokusika ngokuya ngezidingo ezithile zamakhasimende zomshini.
Ukukhiqizwa kwamathuluzi ajwayelekile ikakhulukazi ukusika inani elikhulu lensimbi evamile noma izingxenye ezingezona ezensimbi. Lapho ucezu lokusebenzela luphathwe ukushisa futhi ubulukhuni bukhuphuka noma ezinye izidingo ezikhethekile ze-workpiece azikwazi ukunamathela ethuluzini, ithuluzi elijwayelekile lingase lingakwazi ukuhlangabezana nalokhu Ngokwezidingo zokusika, kuyadingeka ukwenza ukukhiqizwa okuhlosiwe kwento ethize. ukukhethwa kwezinto ezibonakalayo, i-angle enqenqemeni yokusika kanye nokuma kwethuluzi lamathuluzi ensimbi ye-tungsten ngokusho kwezidingo ezikhethekile zezingxenye ezicutshunguliwe.
Imimese yensimbi engajwayelekile eyenziwe ngokwezifiso ye-tungsten ihlukaniswe yaba izigaba ezimbili: leyo engadingi ukwenziwa ngokwezifiso okukhethekile kanye naleyo edinga ukwenziwa ngokwezifiso okukhethekile. Asikho isidingo samathuluzi ensimbi enziwe ngokwezifiso e-tungsten angewona ajwayelekile ukuze axazulule izinkinga ezimbili: izinkinga zosayizi kanye nezinkinga zokuqina kwendawo.
Ngenkinga yesayizi, kufanele kuqashelwe ukuthi umehluko wesayizi akufanele ube mkhulu kakhulu, futhi inkinga ye-roughness ebusweni ingafinyelelwa ngokuguqula i-engeli yejometri ye-edge yokusika.
Amathuluzi ensimbi enziwe ngezifiso ama-tungsten akhethekile axazulula izinkinga ezilandelayo:
1. I-workpiece inezidingo ezikhethekile zomumo. Kumathuluzi anjalo angajwayelekile, uma izidingo zingenzima kakhulu, kulula ukuhlangabezana nezidingo. Kodwa-ke, kufanele kuqashelwe ukuthi ukukhiqizwa kwamathuluzi angajwayelekile kunzima ukukhiqiza nokucubungula. Ngakho-ke, umsebenzisi kungcono ukuthi angahlangabezani nemibandela yokukhiqiza nokucubungula. Idinga izidingo zokunemba eziphakeme kakhulu, izidingo zokunemba okuphezulu ziwumfanekiso wezindleko nobungozi obukhulu.
2. I-workpiece inamandla akhethekile nobulukhuni. Uma i-workpiece ithole ukwelashwa kokushisa, ubulukhuni namandla amathuluzi ajwayelekile angeke ahlangabezane nenqubo yokusika, noma ukunamathela kwethuluzi kubi kakhulu, okudinga izidingo ezengeziwe zento ethile yethuluzi elingajwayelekile. Amathuluzi e-carbide ekhwalithi ephezulu, okungukuthi amathuluzi ensimbi ye-tungsten ephezulu, ayisinqumo sokuqala.
3. Izingxenye zomshini zinezidingo ezikhethekile zokususwa kwe-chip kanye nokubamba i-chip. Lolu hlobo lwethuluzi lusetshenziselwa ikakhulukazi izinto ezisebenza kalula
Ekwakhiweni nasekukhiqizeni amathuluzi ensimbi ye-tungsten angajwayelekile, kunezinkinga eziningi okufanele zinakwe:
1. I-geometry yethuluzi iyinkimbinkimbi, futhi ithuluzi lijwayele ukuguqulwa phakathi nenqubo yokwelashwa kokushisa, noma ukucindezeleka kwendawo kugxile kakhulu, okudinga ukunakwa kwezidingo zokushintsha ukucindezeleka kwendawo lapho ukucindezeleka kugxile khona.
2. Imimese yensimbi ye-Tungsten iyizinto eziphukayo, ngakho-ke udinga ukunaka kakhulu ukuvikelwa komumo we-blade ngesikhathi sokucubungula okuthile. Uma izimo ezingajwayelekile zenzeka, zizodala umonakalo ongadingekile emimese.
