There is a primary need for linear guidance systems that provide consistent repeatable performance. This is especially important in the field of large format digital image scanning, where it has broadened into many fields such as architectural drawings, mapping, and medical x-rays. In addition, output devices such as ink jet printers and plotters are continuing to increase in resolution and size for creating posters, billboards, signs, and many other various applications. In all these areas, the need for clean scans and output without the distraction and interference of artifact lines can have costly and even devastating results. Consistency in this motion is the essential factor in developing a successful scanner design.
Positional accuracy vs. repeatability, and equally applied torque are two major factors that help provide consistency in linear motion for imaging applications. In this white paper, we compare data on a traditional type of slide built from components versus our Uni-Guide linear guide system. The unpredictability in the variations of the carriage within the slide is critical when controlling the amount of variance built into the base components. The one-piece rails of Uni-Guide have an inherent accuracy built into the design and manufacturing process that cannot be duplicated with the built-up components of traditional dual rail systems. This helps to eliminate tolerance stack up, dampen vibrations and shock loads, and offer the ability to drop into existing applications, making installation easy.
Within the Eliminate Artifact Lines with Consistent Linear Motion white paper, we discuss the basics of linear slide accuracy and the factors contributing to consistent torque, along with a comparison of slide options, and a rail report and analysis.
