Precision granite mechanical components, made of high-quality “Jinan Blue” stone, are processed by machinery and finely ground by hand. have high precision, no deformation, good stability and long service life.
\nWe can process various components for the user, such as granite base columns, beams, and guides for threecoordinate measuring machines. We can also process various granite bases, gantries, and slides for printed circuit board drilling, milling, and engraving machines.
\nWe can process irregular products for the user.
\nThe perfect combination of granite with metal and electronics.<\/p>\n

Ventajas:
\n1. High precision, good stability, and not easy to deform which can guarantee the measurement accuracy at room temperature.
\n2. Will not rust, resistant to acid and alkali, no need for special maintenance.
\n3. Good wear resistance long service life.
\n4. Los ara\u00f1azos y golpes en la superficie de trabajo no afectan a la precisi\u00f3n de la medici\u00f3n.
\n5. No hay problemas de magnetizaci\u00f3n.
\n6. It slide smoothly without any drag during measurement.<\/p>\n
