Silicio karbido abrazyviniai diskai yra idealus pasirinkimas \u0161lifuojant ma\u017eo tempimo stiprio med\u017eiagas, pavyzd\u017eiui, metalus ir nemetalus, ta\u010diau juos gali b\u016bti sud\u0117tingiau valdyti nei aliuminio oksido abrazyvus d\u0117l a\u0161tri\u0173 gr\u016bdeli\u0173, kurie lengvai pjauna stikl\u0105, plastik\u0105 ir vidutinio tankio medienos plau\u0161o plok\u0161tes, ta\u010diau negali pjauti kietesni\u0173 med\u017eiag\u0173, pavyzd\u017eiui, metalo ar kietmed\u017eio.<\/p>\n
Silicio karbidas, kurio kietumas pagal Moso skal\u0119 yra 9,5, yra vienas i\u0161 kie\u010diausi\u0173 \u012fprast\u0173 abrazyvini\u0173 gr\u016bdeli\u0173 ir d\u0117l a\u0161tri\u0173 briaun\u0173 ir trapumo idealiai tinka kietoms med\u017eiagoms \u0161lifuoti ar poliruoti. D\u0117l savo ilgo tarnavimo laiko ir galimyb\u0117s perdirbti \u0161i med\u017eiaga ypa\u010d gerai tinka tokiems metalams kaip titanas, ner\u016bdijantis plienas, \u0161arvuotas aliuminis, ta\u010diau gali b\u016bti sud\u0117tinga dirbant su subtilesniais pavir\u0161iais, pavyzd\u017eiui, stiklu ir marmuru.<\/p>\n
Kiti abrazyvai, pavyzd\u017eiui, aliuminio oksidas ar cBN, pasi\u017eymi ne tokiomis geromis pjovimo savyb\u0117mis ar ilgaam\u017ei\u0161kumu; d\u0117l nepakankamo atsparumo l\u016b\u017eiams cirkonio oksidas yra geresnis pasirinkimas \u0161lifuojant kietesnes med\u017eiagas, pavyzd\u017eiui, gr\u016bdint\u0105 plien\u0105; d\u0117l savo patvarumo jis taip pat yra optimalus pasirinkimas dirbant su aliuminiu, gele\u017eimi ir mink\u0161tomis bronzos med\u017eiagomis. Pirmoji kiekvieno rato specifikacijos raid\u0117 paprastai nurodo, kokio tipo gr\u016bdai jame yra: A rei\u0161kia aliuminio oksido abrazyvus, pvz., aliuminio oksid\u0105; B - cBN; C - silicio karbid\u0105, o Z - cirkonio oksido abrazyvus.<\/p>\n
Gr\u016bd\u0117tumas rei\u0161kia atskir\u0173 abrazyvini\u0173 daleli\u0173 dyd\u012f ir sukibimo stiprum\u0105, nes didesn\u0117s dalel\u0117s yra didesnio gr\u016bd\u0117tumo, tod\u0117l geriau tinka grubiam mink\u0161t\u0173 med\u017eiag\u0173 \u0161lifavimui, o ma\u017eesn\u0117s dalel\u0117s yra linkusios pjauti grei\u010diau, j\u0173 a\u0161trumas ir pjovimo greitis yra didesni. Adheziniai ry\u0161iai tvirtai laiko \u0161ias daleles j\u0173 ratuose - \u0161lifavimo diskuose da\u017eniausiai naudojami stikli\u0161ki arba dervos ry\u0161iai.<\/p>\n
\"Sol Gel Alpha Alumina Abrasives\" istori\u0161kai buvo sunku naudoti su aliuminio oksidu dengtais ratais d\u0117l kampus laikan\u010di\u0173 jung\u010di\u0173, kuri\u0173 sud\u0117tyje yra aliuminio oksido, reaguojan\u010dio su gr\u016bd\u0117tumu, oksiduojan\u010dio j\u012f ir sukelian\u010dio pernelyg didel\u012f rato strukt\u016bros susitraukim\u0105. Naujoji, \u010dia apra\u0161yta, be aliuminio oksido jungtis pasi\u017eymi didesniu mechaniniu tvirtumu ir atsparumu formos praradimui, tod\u0117l ja lengviau \u0161lifuoti metalus ir kietas med\u017eiagas nei tradicin\u0117mis jungtimis, kuriose yra aliuminio oksido, pavyzd\u017eiui, Kentukio rutuliniu moliu Nr. 6, Nefelino sienitu arba flintu; \u0161ias jungtis taip pat galima degti \u017eemesn\u0117je temperat\u016broje, kad jos nereaguot\u0173 su savo gr\u016bdeliais.<\/p>\n
Sukibimas - tai med\u017eiag\u0173, laikan\u010di\u0173 abrazyvinius gr\u016bdelius ant rato, tvirtumas, o \u012fvairi\u0173 r\u016b\u0161i\u0173 sukibimai naudojami kuriant skirtingus abrazyvinius diskus, kurie geriausiai tinka tam tikroms med\u017eiagoms ar reikm\u0117ms.<\/p>\n
Aliuminio oksidas, dar \u017einomas kaip korundas, yra populiarus ri\u0161amasis abrazyvas, naudojamas juodiesiems metalams ir spalvotosioms med\u017eiagoms, pavyzd\u017eiui, keramikai, \u0161lifuoti. Be to, \u0161i\u0105 med\u017eiag\u0105 da\u017enai galima rasti galandant karbidinius \u012frankius.<\/p>\n
\u017daliasis silicio karbidas, kietesn\u0117 ir trapesn\u0117 med\u017eiaga nei korundas, da\u017enai naudojamas stikli\u0161kose klijuot\u0117se ir diskuose, skirtuose ma\u017eo tempimo stiprio spalvotiesiems metalams, pvz., cementuotajam karbidui, ir kietoms trapioms med\u017eiagoms, pvz., cementuotajam karbidui, \u0161lifuoti.<\/p>\n
Abrazyvin\u0117 med\u017eiaga specialiu \u0161lifavimo b\u016bdu suformuojama \u012f norim\u0105 form\u0105 ir sujungiama derva arba stiklu. Priklausomai nuo gr\u016bd\u0117tumo ir suri\u0161imo stiprumo \/ standumo, abrazyvas klasifikuojamas kaip kietas arba mink\u0161tas; paprastai kietos r\u016b\u0161ys geriau veikia kietesnes med\u017eiagas, o mink\u0161tos - mink\u0161tas.<\/p>\n
I\u0161radimo ratuko akytumas yra neatsiejama jo eksploatacini\u0173 savybi\u0173 dalis, kaip rodo jo \u0161lifavimo bandymas su \u0117sdintomis silicio plok\u0161tel\u0117mis: stabili maksimali normalioji j\u0117ga per du \u0161imtus plok\u0161teli\u0173 \u0161lifavimo cikl\u0173, suma\u017einant tiek \u0161iluminius, tiek mechaninius ruo\u0161inio pa\u017eeidimus.<\/p>\n
Prie\u0161ingai nei \u012fprasti su derva suri\u0161ti diskai, i\u0161rastasis diskas pasi\u017eym\u0117jo itin palankiomis \u0161lifavimo savyb\u0117mis \u0161lifuojant \u0117sdintas plok\u0161teles, kad b\u016bt\u0173 i\u0161gautas smulkus apdailos fonas su santykinai pastoviomis did\u017eiausiomis normalin\u0117mis j\u0117gomis ir be staigaus padid\u0117jimo. Prie\u0161ingai \u0161iems rezultatams, \u012fprastinis derva suri\u0161tas lyginamasis ratas pasi\u017eym\u0117jo nepriimtinai greitu did\u017eiausios normaliosios j\u0117gos padid\u0117jimu, d\u0117l kurio jis tapo netinkamas naudoti. Prie\u0161ingai, to paties eksperimento metu \u012fprastinis lyginamasis ratas pasi\u017eym\u0117jo nuolatiniu, staigiu did\u017eiausios normaliosios j\u0117gos did\u0117jimu, d\u0117l kurio j\u0173 ruo\u0161inys tapo netinkamas naudoti; prie\u0161ingai, to paties eksperimento metu, lyginant \u012fprastinius lyginamuosius ratus, jie pasi\u017eym\u0117jo nuolatiniu, staigiu did\u017eiausios normaliosios j\u0117gos did\u0117jimu, d\u0117l kurio jie galiausiai tapo netinkami naudoti; prie\u0161ingai, lyginant to paties eksperimento metu i\u0161rastasis ratas pasi\u017eym\u0117jo labai pageidautinomis \u0161lifavimo savyb\u0117mis, d\u0117l kuri\u0173 buvo i\u0161gautas smulkus apdailos fonas, o did\u017eiausios normaliosios j\u0117gos did\u0117jimas buvo nedidelis ir pastovus.<\/p>\n
\u0160is abrazyvinis \u0161lifavimo ratas turi \u017ealius 60 gr\u016bd\u0117tumo silicio karbido gr\u016bdelius ir stikli\u0161k\u0105 ri\u0161ikl\u012f, sudaryt\u0105 i\u0161 toki\u0173 \u017ealiav\u0173 kaip Kentukio rutulinis molis Nr. 6 molio, nefelino sienito, kempinio ir stiklo frito. Idealiu atveju did\u017eiausia degimo temperat\u016bra netur\u0117t\u0173 vir\u0161yti 1100 laipsni\u0173 C; jo por\u0173 t\u016br\u012f galima kontroliuoti naudojant tu\u0161\u010diavidures keramines sferas, kurios pirmenyb\u0119 teikia reakcijai su jo komponentais, tuo pa\u010diu apsaugant silicio karbido gr\u016bdelius nuo oksidacijos degimo metu.<\/p>","protected":false},"excerpt":{"rendered":"
