Granite base is one of the most commonly used materials for precision assembly devices because of its high stiffness and stability, excellent dampening properties, and resistance to temperature fluctuations. However, to ensure that the granite base performs optimally, certain requirements must be met in the working environment, and proper maintenance must be carried out.
Firstly, the working environment should be well-conditioned to minimize temperature fluctuations and vibrations that may affect the stability of the granite base. Ideally, the temperature should be maintained within a set range that is not too high or too low. High temperatures can cause the granite base to expand, while low temperatures may cause it to contract, which can affect the accuracy of the measurements and the stability of the machine. The humidity level should also be controlled because excessive humidity can cause the granite to absorb moisture, which can lead to corrosion and reduced stability.
Secondly, dust and other contaminants should be kept at a minimum in the working environment. When airborne particles settle on the surface of the granite base, they can cause scratches and other types of damage that can affect the accuracy of the measurements. Therefore, frequent cleaning of the granite base using a soft cloth and mild cleaning agent is recommended. Additionally, the working area should be enclosed or isolated to prevent contaminants and dust from entering the area.
Thirdly, the granite base should be properly supported and leveled to ensure uniform load distribution. Any deflection or bowing of the granite base can lead to accuracy issues and may even cause permanent deformation. Therefore, the mounting surface should be flat, and any gaps in the support structure should be filled with appropriate materials such as epoxy or grout.
Finally, the granite base should be protected from any physical damage, wear, and tear. When handling the granite base, care should be taken to prevent damage to the edges and corners. Additionally, any impact or vibration that may occur during operation should be absorbed by appropriate damping systems such as isolators or shock absorbers.
In conclusion, the requirements for a granite base for precision assembly devices involve ensuring a well-conditioned working environment that is free from dust and contaminants and maintaining proper support and leveling. Proper maintenance involves frequent cleaning, protection from physical damage, and appropriate damping systems to minimize the effect of vibration. By adhering to these requirements, the granite base can perform optimally, leading to accurate and stable measurements for the precision assembly device.
