CNC machine tools of rail damping mean, how to understand it is friction?
With a knife is fixed on the machine tool feed system of CNC turning machine to offset the reduced friction resistance and the friction of the poor, in order to improve the feed system of NC machine tools (improve the guideway and friction characteristics (
Not only increased friction, but also shock absorption seems to be only linear rolling rail, emphasizing the characteristics of friction damping, because the rolling guide friction is small, fast response
Damping: refers to any system of vibration in vibration, because of the characteristics of vibration amplitude caused by external force or the system itself inherent in the gradual decline, and the characteristics of the quantification. The motion state of vibration damping system in vibration attenuation.Rolling linear guide slider damping, including the damping block and the guide rail sealing device, the oil hole is arranged in the guide block and the damping mounting hole, groove guide rail and the guide rail with damping block pair matched, and the lubricating oil film is formed on the damping block and guide rail gap formed to prevent the sealing; for lubricating oil leakage in the fixed end and side guide rail damping block; damping block through mounting holes connected on the moving parts. And with the use of linear rolling guide, can improve the damping of linear rolling guide, reduce body damage, prolong the service life of machine tool guide system.THK overweight load (radial) -THK linear guide NR realized compared with the traditional products are more similar in deep groove ball diameter rolling surface processing, improve the necessary tool of high rigidity, vibration resistance, impact resistance, damping (decay), overweight load type LM rail is the most suitable for the radial load.
