Printing machines usually require high-speed and high-precision movement to ensure the quality and stability of printing effects. The slidability and precision of the linear guideway are required by the printing machine, which can further ensure that no pattern or text is floating during the printing process, so that it has the effect of high inclination and colorful patterns. Printing machines usually need to work for a long time, so the quality and life of the linear guide is also one of the very important considerations.
