CNC stakl\u0117s - tai kompiuterizuotos mechaninio apdirbimo stakl\u0117s. CNC santrumpa kilusi i\u0161 angli\u0161ko termino\u00a0Kompiuterinis skaitmeninis valdymas<\/a>. Pats terminas nurodo pagrindin\u012f \u0161i\u0173 ma\u0161in\u0173 veikimo princip\u0105. Taigi tai yra kompiuteris su skaitmeniniais metodais. Juos teikia specialios programin\u0117s priemon\u0117s, kuriomis valdomos ir stebimos \u0161ios ma\u0161inos ir j\u0173 pagrindiniai komponentai. \u012eranki\u0173 jud\u0117jimu r\u016bpinasi servo arba \u017eingsniniai varikliai. Pagrindinis CNC ma\u0161inos elektroninis blokas vadinamas CNC valdikliu ir gali b\u016bti suprantamas kaip tam tikras tarpinis \u012frenginys tarp kompiuterio ir servovarikli\u0173 arba \u017eingsnini\u0173 varikli\u0173, kurie r\u016bpinasi judesiais pagal visas nustatytas CNC ma\u0161inos a\u0161is.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Koks yra CNC stakli\u0173 veikimo principas?<\/h2>

CNC stakli\u0173 veikimo principas - tikslus med\u017eiagos apdirbimas, kur\u012f u\u017etikrina spaustuvin\u0117 sistema, u\u017etikrinanti, kad med\u017eiaga arba ruo\u0161inys b\u016bt\u0173 fiksuotoje pad\u0117tyje. Detal\u0117 nustatoma tam tikroje vietoje ir lieka joje iki apdirbimo operacijos pabaigos. Da\u017eniausiai CNC stendui pakanka keisti \u012frankio pad\u0117t\u012f trimis pagrindin\u0117mis a\u0161imis X, Y ir Z kryptimis. \u017dinoma, \u0161iandien rinkoje yra labai pa\u017eangi\u0173 CNC stakli\u0173, kurios leid\u017eia \u012frank\u012f judinti keliomis a\u0161imis, jos gali jud\u0117ti iki ne\u012ftik\u0117tin\u0173 a\u0161i\u0173, o pa\u017eangiausios stakl\u0117s gali jud\u0117ti ir daugiau nei a\u0161tuoniomis kryptimis, kurias turi palaikyti\u00a0CNC valdiklis<\/a>. Skirtingai nuo robot\u0173, kurie taip pat yra kompiuteriu valdomos ma\u0161inos ir da\u017eniausiai naudojami gamybos linijose, CNC stakl\u0117se ruo\u0161inys paprastai b\u016bna \u012ftvirtintas kameroje, o operatorius rankiniu b\u016bdu j\u012f \u012fdeda ir i\u0161ima i\u0161 apdirbimo zonos.<\/p>

Kokie yra pagrindiniai CNC stakli\u0173 komponentai?<\/h2>

Kaip min\u0117ta anks\u010diau, kompiuterin\u0117 programa yra CNC stakli\u0173 programavimo pagrindas. Med\u017eiag\u0173 apdirbimo planui sudaryti naudojamos CAD-CAM programin\u0117s priemon\u0117s. \u0160ie br\u0117\u017einiai su planu paver\u010diami G kodu, kur\u012f supranta CNC stakl\u0117s. G-kodas nurodo a\u0161i\u0173, pagal kurias juda stakli\u0173 galvut\u0117, pad\u0117tis. Taigi kiekviena eilut\u0117 nurodo nauj\u0105 stakli\u0173 a\u0161ies pad\u0117t\u012f. Kita vertus, M-kodas apibr\u0117\u017eia \u012fvairias funkcijas, kurios gali b\u016bti susijusios su paleidimu, sustabdymu, padavimo grei\u010diu, \u012franki\u0173 keitimu, kameros dureli\u0173 atidarymu ir pan. Viena i\u0161 toki\u0173 CNC valdymo programini\u0173 \u012frang\u0173 yra \"Mach3\", o dar geriau - modernesn\u0117 jos versija.\u00a0Mach4<\/a>.<\/p>

Kitas labai svarbus komponentas yra mechanin\u0117 ma\u0161inos konstrukcija. Tai labai svarbu siekiant didelio tikslumo ir tvirtumo, kai a\u0161i\u0173 judesiai kartojasi be galo da\u017enai. Ypa\u010d ma\u0161inos mechanin\u0117s konstrukcijos standumas svarbus tikslumui ir pakartojamumui. D\u0117l dideli\u0173 apkrov\u0173 CNC ma\u0161inos da\u017eniausiai yra masyvios ir sunkios. Kad mechaniniai komponentai ilgai tarnaut\u0173, jiems reikia reguliarios ir kruop\u0161\u010dios technin\u0117s prie\u017ei\u016bros, atliekamos i\u0161 anksto nustatytais laiko intervalais, pritaikytais prie stakli\u0173 darbo valand\u0173 skai\u010diaus. Technin\u0117 prie\u017ei\u016bra taip pat turi b\u016bti kruop\u0161\u010diai suplanuota gamybos metu.<\/p>
