Why does Machine Tool Guide Rail use rolling steel balls as the moving medium?
Publish Time: 2024-05-27
Why Machine Tool Guide Rail uses rolling steel balls as the moving medium is mainly based on its unique technical advantages and its important impact on machine tool performance. Here's a detailed breakdown of this choice:
1. Technical advantages of rolling steel balls
Small friction coefficient: The contact between the rolling steel ball and the Machine Tool Guide Rail is point contact. Compared with sliding contact, the friction coefficient is significantly lower. This means that when the machine tool is running at high speed, due to the small friction resistance, it can reduce energy loss and improve the operating efficiency of the machine tool.
High sensitivity: The rolling steel balls circulate in the Machine Tool Guide Rail groove and can quickly respond to the instructions of the machine tool to achieve high-precision and high-sensitivity motion control. This is crucial for machine tools that require high-precision machining.
Long service life: Due to the small friction coefficient, the wear of the rolling steel balls is also reduced accordingly. At the same time, because the steel ball diameter tolerance is controlled within ±20 microns, and screening and classification are performed in 0.5 micron increments, the life of the Machine Tool Guide Rail system has been significantly extended.
2. Impact on machine tool performance
Improve processing accuracy: The high sensitivity of rolling steel balls can ensure that when the machine tool is working, the movement trajectory and position of the worktable, tool holder and other components are accurate to a range of several microns or even smaller, thereby greatly improving processing accuracy.
Improved operating efficiency: Due to the small friction coefficient, the power required by the machine tool during operation is also reduced accordingly, which not only reduces energy consumption, but also improves the operating efficiency of the machine tool.
Reduce maintenance costs: The rolling steel balls have good wear resistance, which extends the maintenance cycle of the Machine Tool Guide Rail system and reduces maintenance costs.
To sum up, Machine Tool Guide Rail uses rolling steel balls as the moving medium, which can not only improve the processing accuracy and operating efficiency of machine tools, but also reduce maintenance costs. It is an important technological innovation in the field of machine tool manufacturing.
