Ultra-Precision Black Granite Surface Plate with Leveling Feet
When your tolerances are measured in sub-microns, the base under your instrument can make or break your readings. Standard shop-floor tables transmit vibrations, expand under ambient temperature shifts, and warp over time.
The ZHHIMG® High-Density Black Granite Surface Plate eliminates these variables entirely. Mined from exclusive natural stone reserves and precision-lapped in our 10,000 m² climate-controlled workshops, this reference stand provides an ultra-stable, non-magnetic, and corrosion-proof base for high-precision inspection.
Equipped with heavy-duty, threaded leveling feet, engineers can calibrate exact horizontality within seconds—making it the preferred choice for metrology institutes, semiconductor cleanrooms, and automated optical inspection (AOI) setups worldwide.

1、Metrology & Calibration Labs: Used as a reference flat for height gauges, dial indicators, roughness testers, and micro-measuring systems.
2、Semiconductor & Microelectronics Assembly: Ideal for mounting microscope stages, laser displacement sensors, and small PCB inspection equipment.
3、Coordinate Measuring Machines (CMM) & Optics: Provides a flat, zero-strain base for optical comparators, laser interferometers, and 3D profilers.
4、Precision Tooling & CNC Calibration: Applied in tool rooms for setting up fixtures, inspecting cut angles, and verifying gauge blocks.
We use various techniques during this process:
● Optical measurements with autocollimators
● Laser interferometers and laser trackers
● Electronic inclination levels (precision spirit levels)

Q1: Why choose ZHHIMG® Black Granite over low-cost marble surface plates?
A: Marble lacks the quartz and dense crystalline matrix found in high-grade black granite. It is softer, more prone to scratching, thermally unstable, and deforms under load. ZHHIMG® Black Granite has a density of ≈ 3100 kg/m³, offering nearly double the wear life and rock-solid flatness over decades.
Q2: How do the adjustable feet help maintain accuracy?
A: Even the flattest granite plate can yield incorrect readings if mounted on an uneven workbench. Our threaded leveling feet allow you to adjust the pitch and roll of the stand easily while isolating ambient vibrations from nearby equipment.
Q3: Does ZHHIMG® provide custom sizes or hole drilling?
A: Yes. As a direct manufacturer operating a 200,000 m² production facility, we offer custom dimensions, threaded inserts, T-slots, clearance holes, and custom air-bearing configurations upon request.
