Custom Precision Black Granite Machine Components for Ultra-Precision Air Bearing Stages
The face is precisely machined with an intricate matrix of staggered, flush-mounted stainless steel threaded inserts for rail/motor mounting. It features complex bore geometries, including a large counterbored through-hole at the top for major routing or axis pass-through, alongside several smaller precision-bored alignment holes. One lateral side has a distinct, perfectly lapped bevel/chamfer, minimizing edge-chipping risks and structural dead-weight.

Ultra-Precision Granite Surface Plate | High-Density (3100kg/m³) Black Granite Base for CMM & Semiconductor Equipment | ZHHIMG®
Unmatched Material Density (3100kg/m³): Our proprietary black granite is significantly denser and more stable than ordinary marble or standard granite. It resists warping and deformation, ensuring your equipment remains perfectly level for decades.
“Hand-Crafted” Nanometer Precision: Technology meets artistry. Our master grinders possess over 30 years of manual lapping experience. Capable of “feeling” micron-level deviations, they hand-polish each plate to achieve nanometer-level flatness. Our clients often call them “Walking Electronic Levels.” -
Black Granite Machine Beam
At ZHONGHUI Group (ZHHIMG®), we refuse to compromise. We do not use commercial marble. We extract our own Jinan Black Granite, yielding a density of ≈ 3100 kg/m³. Natural stone aged over millions of years contains zero internal stress. When our master craftsmen finish hand-lapping these beams, the resulting structural component is practically inert—providing a permanent, sub-micron accurate anchor for your machine’s high-speed moving axes.

High-Precision Custom Granite Machine Base with Integrated T-Slots and Vacuum Ports
Imagine a semiconductor wafer inspection machine. The robotic arm moves rapidly, generating vibration. A steel base would ring like a bell, blurring the camera’s image. This custom granite base absorbs that energy instantly. The threaded inserts visible in the image allow for the precise bolting of guide rails, while the central channel keeps sensitive cabling away from moving parts. The result? Flawless inspection data and higher yield rates.
