Granite is a popular choice for the base of industrial computed tomography (CT) products due to its low coefficient of thermal expansion, high stability, and resistance to vibration. However, there are still some defects or drawbacks associated with the use of granite as a base material for industrial CT products. In this article, we will explore some of these defects in detail.
1. Weight
One of the major drawbacks of using granite as a base for industrial CT products is its weight. Typically, the base of such machines must be heavy and stable enough to support the weight of the X-ray tube, detector, and specimen stage. Granite is a very dense and heavy material, which makes it ideal for this purpose. However, the weight of the granite base can also be a significant drawback. The increased weight can make the machine difficult to move or adjust, and can even lead to damage or injury if not handled properly.
2. Cost
Granite is a relatively expensive material compared to other options, such as cast iron or steel. The cost of the material can add up quickly, especially in high-volume production scenarios. Additionally, granite requires special cutting and shaping tools, which can add to the cost of production and maintenance.
3. Fragility
While granite is a strong and durable material, it is also inherently fragile. Granite can crack or chip under stress or impact, which can compromise the integrity of the machine. This is particularly problematic in industrial CT machines where precision is critical. Even a small crack or chip can result in inaccuracies in the image or damage to the specimen.
4. Maintenance
Due to its porous nature, granite requires special maintenance to keep it in optimal condition. Regular cleaning and sealing are necessary to prevent dirt, grime, and other contaminants from penetrating the surface. Failure to maintain the granite base properly can lead to deterioration over time, which can affect the accuracy and quality of the images produced by the machine.
5. Limited Availability
Granite is a natural material that is quarried from specific locations around the world. This means that the availability of high-quality granite for use in industrial CT machines can be limited at times. This can lead to delays in production, increased costs, and reduced output.
Despite these defects, granite remains a popular choice for the base of industrial CT machines. When properly selected, installed, and maintained, granite can provide a stable and durable foundation that supports high-quality imaging with minimal distortion or error. By understanding these defects and taking steps to address them, manufacturers can ensure the continued success and growth of this critical technology.
