Industry-wide Applications of Marble (Granite) Motion Platforms
Marble motion platforms generally refer to integrated slides consisting of a natural granite precision motion base linear motors / air bearing guides. Relying on five core advantages—low thermal expansion, high damping and vibration reduction, non-magnetic insulation, high rigidity, and long-term deformation resistance—they cover six high-precision fields: semiconductors, optics and lasers, precision inspection, aerospace, scientific research, medical, and display panels. Their positioning accuracy generally reaches ±0.1~1μm, making them suitable for micron/nanometer-level motion scenarios.
