Linear guide rail is placed between the slider and the appropriate ball , the sliding friction between the slider and the rail into a roll , the difference of static friction is small , with excellent mobility , namely the drive signal and mechanical action very short lag time interval , CNC system beneficial to improve the response speed and sensitivity.
1, Drive power dropped significantly, only about one tenth of ordinary machinery .
2, And V-shaped cross roller guides compared to friction can be reduced by about 40 times .
3, Adapted to high-speed linear motion , the instantaneous speed of approximately 10 times greater than the slide rails.
4, To achieve high positioning accuracy and repeatability of positioning accuracy.
Dynamic friction greatly reduces friction movement between them , so as to obtain : a gap can be achieved without movement , the movement of improving the mechanical rigidity of the system .
5, When used in pairs of linear guide , with " error averaging effect" , thereby reducing the basic parts ( rail mounting surface ) of the machining accuracy , reduce manufacturing costs and the difficulty of basic mechanical parts .
6, Linear guide cross-section using a reasonable ratio of arc groove , contact stress is small, greatly improving the ability to undertake and rigidity than the flat contact point with the ball , rolling friction than double circular raceway significantly reduced.
7, The surface of linear guide is hardened, so that the guide rail has good correction of ; central portion to maintain good mechanical properties. Simplifies the design and manufacture of mechanical structures.
