Rolling linear guide rail is placed between the slider and the ball properly, the sliding friction between the slider and the rail into rolling, a small difference of static friction, with excellent mobility, namely the drive signal and mechanical action lag time interval is very short, beneficial to improve the numerical control system response speed and sensitivity.
And V-shaped cross roller guides compared to friction can be reduced by about 40 times.
Suitable for high speed linear motion, the instantaneous speed about 10 times higher than the slide rails.
To achieve high positioning accuracy and repeatability of positioning accuracy.
Dynamic friction, greatly reducing motion frictional resistance between the two, so as to obtain: to achieve seamless movement, the movement of improving the mechanical rigidity of the system.
Drive power dropped significantly, only about one-tenth of ordinary machinery.
Guide the use of surface hardening, so that the guide rail has good correction of; core section to maintain good mechanical properties. Simplifies the design and manufacture of mechanical structures. When used in pairs guideway, with "error homogenizing effect", thereby reducing the basic parts (rail mounting surface) of the machining accuracy and reduce the manufacturing cost and difficulty of basic mechanical parts.
Guideway raceway section using reasonable ratio of arc groove, contact stress is small, greatly improving the ability to undertake and stiffness than the flat contact point with the ball, rolling friction than double circular raceway significantly reduced.
