The guide rails used by the cutting machine are divided into circular guide rails and linear guide rails. This is mainly different from the appearance. The circular rail is circular in appearance, and the linear rail is also called square rail, which is cuboid in appearance. At present, the linear guide rails of Taiwan Shangyin or Taiwan Yintai are used in the market. Round rails are generally used in engraving machines. How should we choose a CNC wood router?
1. From the point of view of friction and load bearing capacity, the square guide is the square linear guide with surface contact friction, which has large friction force and uniform load. It needs to be lubricated frequently. The friction of the circular guide is small. Because it is a series of The point contact of the balls requires limited support, poor rigidity, limited load capacity, and relatively small axial load. Moreover, the square track is wear-resistant, high-speed, and has low resistance, so it has more advantages.

2. The linear guide has high positioning accuracy, small friction coefficient, and the gap between static friction and dynamic friction is very small. Even in the case of micro-motion, there will be no idling and slipping, so the CNC wood router can maintain the linear guide for a long time. Positioning accuracy of rolling friction.
3. Linear guides are only assembled on the installation planes milled or ground by large-scale five-sided milling machines. They are assembled with a specific process, which can not only reproduce the machining precision of linear guides, but also reduce the time and cost of traditional planer processing. And because its installation is easy and interchangeable, the slider can be arbitrarily assembled on the same type of guide rail, while maintaining the same smoothness and precision.
