ZHHIMG® Precision Granite Assembly

What you see is not just stone; it is ZHHIMG® Black Granite, a material carefully selected for its exceptional physical properties. With a density of approximately 3100kg/m³, this granite offers a level of mass and structural integrity that far exceeds standard marble or architectural stone. For engineers in the USA and Europe, this translates to an unshakable foundation with a near-zero coefficient of thermal expansion. This ensures that whether you are integrating a linear motor platform or a high-speed AOI system, your datum remains stable regardless of minor ambient temperature fluctuations.

Product Details and Engineering Excellence

This assembly is engineered to be the "chassis" of a high-precision machine. Key features include:

•   Integrated T-Slots and Inserts: Precision-machined slots and threaded inserts are integrated directly into the granite, allowing for the direct mounting of high-precision guide rails and drive systems without compromising the stone's flatness.
•   Ultra-Precision Flatness (Grade 00): Every mounting surface is hand-lapped by our master craftsmen—our "walking electronic levels"—to meet or exceed DIN 876, JIS, and ASME standards.
•   Vibration Damping: The natural gabbro-diabase structure of our black granite absorbs the micro-vibrations generated by high-speed motion, ensuring that your sensors can capture data without "noise."
•   Custom Geometric Tolerances: The perpendicularity between the vertical gantry and the horizontal base is achieved through meticulous hand-lapping, ensuring that the XY-Z relationship is mechanically perfect before you even turn on your software compensation.
