The granite base is a popular choice for the manufacturing industry, particularly for the base of a coordinate measuring machine (CMM). The unique physical characteristics of the granite make it an ideal material for this application. Here are some of the reasons why:
1. High stiffness and stability
Granite is a very stiff material with low thermal expansion. It is also highly resistant to vibration and deformation, which makes it an excellent choice for the base of a CMM. The stiffness of the granite ensures that the base will not deform under heavy loads, and the low thermal expansion ensures that the base will remain stable even when there are temperature fluctuations in the environment.
2. Low thermal sensitivity
The granite base is highly resistant to thermal distortion, making it an ideal material for a CMM base. The lower the thermal sensitivity, the less the base will be influenced by temperature changes in the environment, which can affect the accuracy of the measurements taken by the machine. By using a granite base, the CMM will be able to maintain its accuracy over a wide range of temperatures.
3. High wear resistance
Granite is a hard and durable material that is highly resistant to wear and tear. This makes it the perfect material for a CMM base, which needs to be able to withstand the constant movement of the machine's measuring arm without wearing down or losing its accuracy. The high wear resistance of the granite ensures that the base will maintain its shape and stability over time, even with continuous use.
4. Easy to machine
Granite is a relatively easy material to machine, which makes it an attractive choice for manufacturers. Despite its hardness, granite can be cut and shaped with the right tools, allowing manufacturers to create a perfect fit for the CMM components. The ease of machining granite is also cost-effective, reducing manufacturing time and overall cost.
5. Low friction
Granite has a low coefficient of friction, which makes it an ideal material for a CMM base. The low friction ensures that the machine's measuring arm can move smoothly and accurately across the surface of the base, without any resistance that could affect the accuracy of the measurements.
In conclusion, the unique physical characteristics of granite make it a suitable material for the base of a coordinate measuring machine. Its high stiffness and stability, low thermal sensitivity, high wear resistance, easy machinability, and low friction make it an ideal choice in the manufacturing industry, where accuracy and precision are crucial. The use of granite base ensures that the CMM will perform well over a long period.
