A precision granite is a specialized type of surface plate used for measuring and inspecting dimensional accuracy and flatness of mechanical parts and assemblies. It is typically made of a solid block of granite, which is highly stable and resists deformation even under heavy loads and temperature changes.
Precision granites are widely used in industrial applications such as metrology, machine shops, and aerospace engineering. They are essential tools for ensuring the precision and accuracy of machined parts and assemblies, as well as for verifying the performance of equipment and instruments.
One of the key advantages of precision granites is their high degree of flatness and surface quality. Granite is a naturally occurring stone with an exceptionally smooth surface, making it ideal for use as a measuring and inspection surface. Moreover, precision granites are carefully ground and lapped to obtain a flatness tolerance of less than 0.0001 inches per linear foot, ensuring the highest level of accuracy and repeatability.
In addition to their high accuracy and stability, precision granites offer other benefits as well. They are highly durable and resistant to wear and corrosion, making them a cost-effective investment for long-term use. They also provide a non-magnetic and non-conductive surface, which is important for applications such as electronic testing and inspection.
To maintain the accuracy and effectiveness of a precision granite, it is important to handle it with care and store it properly. To prevent damage or distortion, it should be stored on a stable and level surface and protected from impacts, vibration, and extreme temperatures. Regular cleaning and surface inspection are also necessary to remove debris and ensure that the surface remains flat and free from defects.
In conclusion, a precision granite is an essential tool for maintaining the highest level of dimensional accuracy and flatness in mechanical parts and assemblies. Its high accuracy, stability, and durability make it an excellent investment for industrial applications. With proper handling and maintenance, a precision granite can provide a lifetime of reliable performance and accuracy.
