Ultra-Precision Granite Surface Plate | High-Density (3100kg/m³) Black Granite Base for CMM & Semiconductor Equipment | ZHHIMG®

Short Description:

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.”

    Product Introduction

    The Unshakable Foundation of Ultra-Precision Measurement

    In the world of nanometer-level manufacturing, stability isn't just a requirement—it's everything. Introducing the ZHHIMG® Precision Granite Surface Plate, the gold standard for metrology labs, semiconductor assembly, and high-end CNC machining worldwide.
    Unlike competitors who cut corners with porous, unstable marble, we strictly utilize our proprietary ZHHIMG® Black Granite. With a crushing density of ≈3100kg/m³, our material offers superior physical performance over standard European and American granites. It is completely non-magnetic, rust-proof, and boasts an ultra-low thermal expansion coefficient. When you choose ZHHIMG, you aren't just buying a stone slab; you are investing in the "North Star" of your entire measurement system.

    Application Scenarios

    1. The granite is after a long-term natural aging, the organizational structure is uniform, the expansion cofficient is small, the internal stress completely disappeared.

    2. Not afraid of acid and alkali corrosion, will not rust; do not need oiling, easy to maintain, long service life.

    3. Not limited by the constant temperature conditions, and can maintain the high precision at room temperature.

    No be magnetized, and can move smoothly while measuring, no tight feeling, free of the affect of moisture, good flatness.

    Quality Control

    We use various techniques during this process:

    ●  Optical measurements with autocollimators

    ●  Laser interferometers and laser trackers

    ●  Electronic inclination levels (precision spirit levels)

    FAQ

    Q: Why is ZHHIMG® Black Granite better than standard marble or other granites?
    A: Ordinary marble has a lower density (approx. 2700kg/m³) and is prone to micro-deformation due to temperature changes and internal stress. ZHHIMG® Black Granite (≈3100kg/m³) is physically superior, offering exceptional rigidity and long-term stability. We strictly refuse to use cheap marble substitutes, ensuring you get genuine, high-performance material.

    Q: What is your production lead time for a custom-sized surface plate?
    A: Thanks to our 4 dedicated production lines and massive raw material stock (20,000m² yard), we offer some of the fastest turnaround times in the industry. For standard sizes, we often have stock ready to ship. For large custom orders (e.g., 5000mm+), our monthly capacity exceeds 20,000 sets. Contact us with your dimensions for an instant quote.
    Q: How do you ensure the accuracy during shipping?
    A: We understand the value of precision. All plates are calibrated in our constant temp & humidity workshop. Before shipping, we issue a calibration certificate from the Jinan or Shandong Provincial Metrology Institute (traceable to NIM China). For export, we use heavy-duty, shock-absorbent wooden crates designed to protect the surface finish and structural integrity during transit.
