Precision Metrology: Introducing the ZHHIMG Granite Surface Plate

Our Granite Surface Plates are engineered to the highest international standards, offering distinct advantages for professional metrologists and quality control teams:

●   Exceptional Flatness and Accuracy: Crafted from select natural black granite (diabase), our plates offer superior flatness grades (e.g., Grade 0, Grade 00, or Laboratory Grade) that exceed DIN 876 or ASME B89.3.7 specifications, ensuring reliable measurement accuracy.

●   Thermal Stability: Granite exhibits a low coefficient of thermal expansion. This crucial property minimizes dimensional changes caused by temperature fluctuations, maintaining measurement integrity in varying workshop conditions.

●   Superior Durability & Low Maintenance: Unlike metal alternatives, granite is non-magnetic, non-rusting, and practically impervious to wear. It also resists nicks and scratches, which would raise burrs on metal plates, thereby avoiding potential measurement errors.

●   Enhanced Vibration Damping: The natural density and composition of the granite provide excellent vibration-damping characteristics, stabilizing delicate measuring instruments like height gauges and coordinate measuring machines (CMMs).

●   Customizable Configurations: Available with optional features, including tapped holes, T-slots, or specialized air-bearing systems (as shown in the product image) for precise, frictionless movement of heavy workpieces or CMM structures.
