Imashini yububiko bwa Granite yububiko no gufata neza: Isahani yuzuye ya granite isaba gutunganya no kuyitaho kugirango ibe yuzuye kandi irambe. Mbere yo Kuringaniza, igice cya granite kigomba gukorerwa imashini yambere gutunganya no gutambuka gutambitse hashingiwe kumahame ya mpandeshatu. Nyuma yo gusya gutambitse, niba imashini ya CNC idashobora kugera kubisobanuro bisabwa - mubisanzwe igera ku cyiciro cya 0 (kwihanganira 0.01mm / m nkuko bigaragara muri DIN 876) - no kurangiza biba ngombwa kugirango ugere ku manota yo mu rwego rwo hejuru nka Grade 00 (kwihanganira 0.005mm / m kuri ASTM B89.3.7).
Igikorwa cyo gutunganya kirimo intambwe nyinshi zingenzi. Ubwa mbere, gusya bikabije bishyiraho uburinganire bwibanze, bigakurikirwa na kimwe cya kabiri kirangiza kugirango gikureho ibimenyetso. Gusya neza, akenshi bikorwa nintoki, binonosora ubuso kugirango ugere kubushake bwo kwihanganira uburinganire no gukomera (Ra agaciro ka 0.32-0.63μm, aho Ra igereranya imibare isobanura gutandukana kwishusho yubuso). Hanyuma, ubugenzuzi bwitondewe butuma hubahirizwa ibipimo bya tekiniki, hamwe ningingo zapimwe zashyizwe muburyo bwa diagonal, impande, na midline - mubisanzwe amanota 10-50 bitewe nubunini bwa plaque - kugirango hamenyekane neza ukuri.
Gukemura no kwishyiriraho ingaruka zigaragara neza. Bitewe na granite idasanzwe (Mohs hardness 6-7), guterura bidakwiye birashobora gutera ihinduka rihoraho. Kubisabwa byingenzi bisaba icyiciro cya 00 cyuzuye, gukubita intoki nyuma yo kwishyiriraho ni ngombwa kugirango ugarure ukuri kwangiritse mugihe cyo gutwara. Uku kwitondera amakuru arambuye gutandukanya premium precision granite isahani yububiko busanzwe bukoreshwa.
Imyitozo yo gufata neza igira ingaruka ku mikorere no mu gihe cyo kubaho. Tangira usukuye neza ukoresheje isuku ya pH idafite aho ibogamiye - irinde ibintu bya acide bishobora gutera hejuru. Buri mwaka kalibrasi hamwe na laser interferometero, ikurikiranwa na NIST, itanga ibisobanuro byukuri. Mugihe ushyira ibihangano, emera kuringaniza ubushyuhe (mubisanzwe iminota 15-30) kugirango wirinde amakosa yo gupimwa kubitandukanye n'ubushyuhe. Ntuzigere unyerera ibintu bigoye hejuru yubuso, kuko ibi birashobora gukora micro-scratches bigira ingaruka kuburinganire.
Amabwiriza akoreshwa neza arimo kubahiriza imipaka yimitwaro kugirango hirindwe imiterere yimiterere, kubungabunga ibidukikije bihamye (ubushyuhe 20 ± 2 ° C, ubuhehere 50 ± 5%), no gukoresha ibikoresho byabugenewe kugirango wirinde kwangirika kwindege. Bitandukanye na metero nini, granite yumuriro (0.01ppm / ° C) igabanya ingaruka z’ibidukikije, ariko impinduka zitunguranye zigomba kwirindwa.
Nka gikoresho fatizo mubipimo byuzuye, ibyapa bya granite byemewe (ISO 17025 byemewe) bikora nkibipimo ngenderwaho byo gupima ibipimo. Kubungabunga bisaba imbaraga nkeya - guhanagura gusa hamwe nigitambara kitarimo lint nyuma yo gukoreshwa - nta mwenda udasanzwe cyangwa amavuta akenewe. Mugukurikiza ibyo gutunganya no kwita kuri protocole, plaque ya granite yuzuye itanga imikorere yizewe mumyaka mirongo, bigatuma iba ingirakamaro muri laboratoire ya kalibrasi, gukora ibyogajuru, hamwe nibikorwa bya tekinoroji.
