German INA KWE15H-G3-V1 sliding block has high working accuracy: the movement of the linear guide is realized by rolling, not only the friction coefficient is reduced to 1/50 of the sliding guide, but the difference between dynamic and static friction resistance is also reduced to achieve smooth movement. Reduce impact and vibration, not easy to produce crawling phenomenon, so it can achieve UM-level feed and positioning accuracy, which is beneficial to improve the response speed and sensitivity of CNC coefficients. Significantly reduce the driving rate: because the friction force is very small when the linear guide moves, only a small amount of power is required to make the machine move, and the power loss of the machine is obviously large, and the heat generated by friction is small, which is suitable For high-speed, frequent starting and reversing moving parts. The lubrication structure is simple: the linear guide is equipped with an oil cup on the slider, which can directly inject the grease with oil, and can also be connected to the oil supply pipe for automatic lubrication of the lubricating machine, so that the wear is reduced to less, and the master can be maintained for a long time jobs.
