There are two types of guide rails for CNC Wood Router, one is round rails and the other is square rails. The difference between these two types of guide rails is: round guide rails have high bearing capacity and average precision. Due to their relatively low cost, short production cycle, and easy installation, round guide rails have become a substitute for square linear guide rails in many occasions.
Product features of linear guide rails: High positioning accuracy and good reproducibility The rolling motion of linear guide rails has a particularly small friction coefficient, especially the difference between static friction and dynamic friction is very small, and there will be no idling slippage even when feeding in a small amount , with the best resolution and reproducibility, so it can achieve μm-level positioning accuracy.

Low frictional resistance, can maintain precision for a long time The rolling friction of the linear guide can be reduced to 1/20~1/40 of the frictional resistance of the sliding guide, especially the lubrication structure is simple, the lubrication is easy, the lubrication effect is excellent, and the wear of the friction contact surface is the lowest Bottom, so walking accuracy can be maintained for a long time. The optimal design of the geometric mechanical structure that can bear high load capacity in four directions can bear the loads in the radial direction, reverse radial direction and transverse direction at the same time, and maintain the running accuracy. It can improve performance and load capacity. It is suitable for high-speed applications due to its small frictional resistance, low demand for driving horsepower of equipment, and great energy saving effect, especially small motion wear and low temperature rise effect, which can realize the requirements of mechanical miniaturization and high speed at the same time.
