Core strengths
Physical properties of natural materials
Zero metal fatigue: uses Jinan Green/Indian Black granite, with a Vickers hardness of Mohs 6-7, and an abrasion lifespan exceeding 20 years.
Thermal stability: The coefficient of thermal expansion is only 3.5×10⁻⁶/°C, with temperature change resistance three times that of cast iron bases. When temperature fluctuates by ±5°C, planarity variation is ≤0.5μm/m.
Damping vibration reduction: The inherent vibration decay coefficient reaches 0.15, capable of absorbing more than 80% of high-frequency mechanical vibrations.
01
Micron-level geometric precision
Ultra-precision grinding: flatness error compliant with ISO 9001 standard.
Long-term stability: annual natural deformation is less than 1 micrometer, calibrated regularly with a laser tracker.
02
Modular design
Multi-interface pre-fabrication: supports air float vibration isolation pads, vacuum suction slots, and T-shaped positioning slots (with options for 25mm or 50mm spacing).
Enhanced compatibility: Can integrate linear scale rails, temperature control system (±0.1℃ constant temperature, optional).

do you have any question?
Q1：Why choose granite over metal for the base material?
A: Thermal stability: Granite has a thermal expansion coefficient of 3.5×10⁻⁶/°C, which is only one-third that of cast iron, resulting in less deformation during temperature fluctuations;
Vibration damping performance: Natural granite can absorb more than 80% of mechanical vibrations, preventing high-frequency micro-vibrations of the engraving head;
Zero risk of rust: No issues with metal oxidation, making it suitable for humid environments such as PCB circuit board engraving workshops.
Q2：How to verify the flatness precision of the granite base?
A: • Each base is tested with a laser interferometer before leaving the factory, accompanied by an ISO 9001 test report;
• Third-party testing agencies (such as SGS, TÜV) are available for on-site retesting.
Q3：Do you support custom non-standard sizes? What is the maximum size you can achieve?
A: • Customizable size range: 300×300mm to 5000×10000mm;
• For oversized dimensions, a modular design is used, with a fitting accuracy of ≤5μm (requires pre-installed locating pin holes).
Q4：Can it be compatible with different brands of engraving machines (such as Trumpf, Mitsubishi)?
A: • We offer three pre-designed interface options: T-slot, vacuum suction slot, and threaded hole.
• Customers need to provide the equipment model and interface drawings, and we will design a suitable solution for free.
