Design of the rail system, and strive to have the greatest contact area between the fixed element and a moving element, which not only can increase the carrying capacity of the system, and the system can withstand the impact of intermittent cutting or cutting generated gravity, the force is spread widely, expand bear force area. To achieve this, the shape of the groove of the rail system are varied, there are two representative, called Gothic (pointed arch), extending in semicircular shape, the contact point of the vertex; another arc-shaped rails rust species, can also play the same role. No matter what kind of structure, purpose and only one rail brand, and strive for more contact with the rail rolling ball radius (fixed components). Factors determining system performance characteristics are: how the rolling element contact with the rail, which is the crux of the problem. Linear Rolling Guide performance characteristics. Assemble and easy interchangeability with conventional sliding rail track surface must perform scraping linear guide, both cumbersome and time-consuming, and once the machine precision poor rail must Zaigua research once. Rolling guide interchangeable, just replace the entire scroll slider or rail or guideway, to regain the high-precision machine tools.
