Frequently Asked Questions about Granite Plane Parallel Rule
Granite Plane Parallel Rules offer several benefits, including high resistance to corrosion, exceptional hardness, and minimal thermal expansion. These properties ensure long-lasting accuracy and durability, making them ideal for precision measurements. Additionally, granite requires less maintenance compared to other materials, providing a cost-effective solution for your measurement needs.
Granite has a significantly lower coefficient of thermal expansion compared to steel. This means that granite experiences less dimensional change with temperature variations, ensuring more stable and accurate measurements. This property makes Granite Plane Parallel Rules particularly suitable for environments with fluctuating temperatures.
Granite Plane Parallel Rules are available in various dimensions to suit different measurement needs. Some of the available sizes include 200 x 150 x 30 mm, 300 x 200 x 40 mm, 400 x 250 x 50 mm, 630 x 400 x 60 mm, 800 x 500 x 80 mm, and 1000 x 630 x 100 mm. Each dimension is designed to meet specific perpendicularity and parallelism standards.
Maintaining Granite Plane Parallel Rules is straightforward. Regularly clean the surfaces with a soft, lint-free cloth to remove dust and debris. Avoid using harsh chemicals or abrasive materials. Store the granite squares in a stable environment to prevent damage. Periodic calibration checks are recommended to ensure continued accuracy.
The perpendicularity and parallelism specifications vary based on the dimensions of the Granite Plane Parallel Rules. For example, a 200 x 150 x 30 mm rule has a perpendicularity of 4 µm, while a 1000 x 630 x 100 mm rule has a perpendicularity of 12 µm. Parallelism specifications include 5 µm for 150 x 30 x 17 mm and 8 µm for 300 x 50 x 25 mm. These precise specifications ensure high accuracy in measurements.
