[0002] Linear guides for CNC machine tools are important mechanical components, primarily used to achieve precise linear motion of various machine tool components. Linear guides utilize high-precision balls or rollers to enable precise linear motion of machine tool components along the guides. Linear guides utilize high-precision balls or rollers to enable precise linear motion of machine tool components along the guides. Reasonable guide design allows them to withstand the heavy loads generated during machine tool operation, ensuring stable operation. Compared to traditional sliding guides, linear guides offer less friction, significantly improving machine tool efficiency and lifespan.
[0003] Ordinary linear guides are difficult to adjust slightly, resulting in the inability to achieve the required positioning accuracy in situations where high precision is required, affecting processing quality or measurement accuracy, leading to error accumulation due to installation errors, and affecting the overall synchronization and stability of the system.
