Linear motor platform plays a crucial role in modern industrial applications, and the granite precision base as the core support component of linear motor platform, its performance under different temperature and humidity conditions directly affects the stability and accuracy of the entire system. In this paper, the main differences in performance of granite precision base of linear motor platform are analyzed from two aspects of different temperature and humidity conditions.
First, we look at the effect of temperature on the performance of granite precision base. At lower temperatures, the hardness and compressive strength of the granite material will be increased, which makes the base have better stability when subjected to heavy loads. However, as the temperature decreases, the coefficient of thermal expansion of the granite also decreases, which may cause the base to produce a small size change when the temperature changes, thus affecting the positioning accuracy of the linear motor. In addition, at low temperatures, the lubricating oil inside the linear motor may become viscous, affecting the motor's motion performance. Therefore, under low temperature conditions, special attention needs to be paid to the preheating of the linear motor platform and the selection of lubricating oil.
On the contrary, in high temperature environment, the thermal expansion coefficient of granite increases, which may cause the size of the base to change, and then affect the positioning accuracy of the linear motor. At the same time, high temperature will also accelerate the oxidation and aging process of granite materials, reduce its hardness and compressive strength, making the base prone to deformation or damage when bearing heavy loads. In addition, high temperature will also affect the performance and life of the internal electronic components of the linear motor, increasing the failure rate. Therefore, under high temperature conditions, appropriate heat dissipation measures need to be taken to ensure the normal operating temperature of the linear motor platform.
In addition to temperature, humidity is also an important factor affecting the performance of granite precision base. In a high humidity environment, granite materials are easy to absorb water, resulting in expansion and deformation. This deformation will not only affect the dimensional accuracy of the base, but also may increase the friction coefficient between the base and the linear motor, reducing the transmission efficiency. In addition, the high humidity is also easy to cause the electronic components inside the linear motor to be damp, causing short circuit or failure. Therefore, in a high humidity environment, it is necessary to take moisture-proof measures, such as installing a sealing cover or using moisture-proof materials.
In low humidity environments, the granite material may shrink due to water evaporation, resulting in a change in the size of the base. Although this change is relatively small, the long-term accumulation may still have an impact on the positioning accuracy of the linear motor. In addition, the dry environment may also cause static electricity, causing damage to the electronic components inside the linear motor. Therefore, in a low humidity environment, it is necessary to maintain an appropriate humidity level to avoid adverse effects on the linear motor platform.
In summary, the performance of granite precision base of linear motor platform is significantly different under different temperature and humidity conditions. In order to ensure the stability and accuracy of the linear motor platform, it is necessary to choose the appropriate granite material and manufacturing process according to the actual working environment, and take the corresponding protective measures.
