Wolamulira wa Granite Square

Chigawo cha granite chimagwira ntchito ngati muyezo woyambira wa geometric, ndipo kugwiritsa ntchito kwake kwakukulu kwa metrological ndiko kuwunika kolondola kwa kulekerera kofunikira kwa geometric:
1. Kuwunika momwe zinthu zilili: Kuwunika kuchuluka kwa kusiyana kwa angular pakati pa axis ya spindle tool, slide motion direction, ndi worktable reference plane—nthawi zambiri kumachitika motsatira ISO 1101 ndikutsimikiziridwa kudzera mu optical alignment kapena dial indicator probing;
2. Kuyang'anira kufanana: Kuzindikira cholakwika cha kufanana pakati pa malo awiri ofanana (monga, nkhope za njanji yotsogolera kapena mawonekedwe otsutsana a workpiece), pogwiritsa ntchito mapulaneti otsutsana a sikweya ngati zizindikiro zotsatirika;
3. Kuyeza kusalala: Kugwiritsa ntchito malo a granite opangidwa ndi kuwala komanso okhazikika pa kutentha—monga momwe zatsimikiziridwa kuti ndi osalala ≤0.5 μm kuposa 100 mm (pa JJG 700–2018)—ngati njira yolondola kwambiri yoyezera kusalala kudzera mu njira ya stylus profilometry kapena interferometric.
