The performance of the guide rail of the CNC woodworking engraving machine determines the processing efficiency and quality of the engraving machine. Then, when purchasing the engraving machine equipment, how should the customer choose the appropriate rail model according to their own processing needs? This requires the customer to understand the type of rail used in the woodworking engraving machine.
The guide rails used in the engraving machine are divided into circular guides and linear guides. This is mainly distinguished from the appearance. The round rail is circular in appearance, and the linear guide rail is also called a square rail, and the appearance is a rectangular parallelepiped. Now the company generally uses Taiwan's silver or Taiwan Intime linear guides and Taiwan TBI, the quality is better than the domestic. Round rails are generally used in advertising engraving machines.
1. Considering friction and load bearing capacity, the square gauge is a surface contact type friction, which has large frictional force and uniform load. It needs to be oiled frequently, but the circular guide rail is a cylindrical linear guide rail. Small, because it is a series of ball point contact, the need for support is limited, the rigidity is poor, the load performance is limited, only the radial load has better bearing capacity, and the axial load is relatively small. Moreover, the square track is wear-resistant, high speed, and low resistance, so it has advantages.
2, linear guide product features high positioning accuracy, reproducibility of the linear guide rolling mechanism, the friction coefficient is particularly small, especially the static friction and dynamic friction is very small, even when the micro-feeding Macau baccarat will not There is a phenomenon of idling and slipping, and the resolution and reproducibility are the best, so that the woodworking engraving machine can maintain the positioning accuracy of the rolling friction force of the linear guide for a long time. Low frictional resistance. It is easy to lubricate and can be reduced to 1/20~1/40 of the frictional resistance of the sliding guide rail. The friction contact surface has the lowest wear and excellent sliding effect. Therefore, the walking accuracy can be maintained for a long time.
Learn about the rail types of woodworking engraving machines and the different properties of different rails. It is possible to select suitable rails and other accessories for the engraving machine according to the machining of the workpiece and the machining process. This will not only better control the procurement cost, but also improve the processing efficiency.
