Granite measuring tools, like our precision granite surface plates, are an ideal reference for inspecting mechanical components and instruments. Crafted from superior natural granite through a meticulous process of mechanical shaping and manual lapping, these tools possess unmatched flatness and stability. Their inherent characteristics—high precision, excellent density, resistance to rust and magnetization, and superior longevity—make them indispensable.
However, the full potential of a granite tool can only be realized when it is correctly installed and leveled. Improper support can lead to warping and deformities, compromising its precision. At ZHHIMG®, we understand that proper support is the first and most critical step. We’ll show you the most effective ways to secure your granite measuring tools, ensuring they perform at their best.
Choosing the Right Support Method
The correct support method depends primarily on the size and weight of your granite tool. We generally recommend two primary support options, each tailored to different applications.
Method 1: The Dedicated Stand
For standard granite measuring tools up to 2 x 4 meters, a dedicated stand is the ideal solution. These stands are typically constructed from welded steel and feature an adjustable leveling system.
- Structure: A standard stand has 5 legs and is equipped with 5 leveling jacks on its top plate. Three of these jacks act as primary support points, while the other two are auxiliary. This 3-point support system is key to ensuring stability and making the leveling process easier.
- Installation: The stand should be placed on a firm, level floor, ideally within a climate-controlled area. The granite plate is then carefully lowered onto the stand. A typical stand height is 800 mm, but this can be customized to suit the specific thickness of your plate and your operational needs. For example, a 1000x750x100 mm granite plate would be paired with a 700 mm stand.
Method 2: Heavy-Duty Jacks & Leveling Screws
For larger, heavier granite measuring tools, using a stand may not provide the necessary stability. In such cases, heavy-duty jacks or leveling screws are the preferred method for direct floor-based support. This method is suitable for virtually all large granite tools and components, providing a sturdy, reliable base that can handle immense weight without the risk of instability.
A Step-by-Step Guide to Leveling
Once your granite tool is properly positioned on its supports, it must be leveled before use. Even the most stable platform cannot function as a precision base if it isn’t perfectly level.
- Initial Setup: Position the granite tool on its supports (stand or jacks). Ensure all support points are firmly in contact with the ground and are not suspended.
- Preliminary Leveling: Use a spirit level, electronic level, or autocollimator to make an initial adjustment to the main support points.
- Fine-Tuning: The three primary support points are used for rough leveling, while the remaining auxiliary points allow for micro-adjustments to achieve the final precision. This step-by-step process ensures the granite plate is perfectly flat and stable.
Beyond Installation: The ZHHIMG® Advantage
At ZHHIMG®, we believe that proper installation is a core component of our commitment to precision. While our granite is naturally aged and stress-relieved to be exceptionally stable, its dimensional integrity can only be maintained with correct support.
Our team of expert technicians is not only skilled in crafting granite to nanometer-level precision but also in providing guidance on its proper use and maintenance. From small-scale plates on custom workbenches to large-scale, multi-ton components secured directly to the factory floor, we ensure every product is set up for success. As a company with ISO 9001, ISO 45001, ISO 14001, and CE certifications, you can trust that our methods are backed by the highest standards in the industry.
