Is the square track good or round?



The motion track of the woodworking engraving machine now has a square linear guide and a circular linear guide. Many of the woodworking engraving machines on the market have a square guide rail and a circular guide rail. In practice, the square guide rail is good or round. What are the guide rails? We all know that the performance of woodworking engraving machines mainly depends on the life of the machine, load weight, accuracy, processing speed, etc. The quality of the guide rails is also an important accessory that affects the performance of the whole machine. The cross section is a circle, and the direction of the motion axis of the engraving machine is exactly at the apex of the circular cross section of the circular guide rail. That is to say, the direct force point of the circular guide rail is actually a line, and the force contact surface of the square guide rail is It is a face. Relatively speaking, the load of the square rail is obviously larger than that of the round rail, and after a long running-in, the loss rate of the circular guide rail is certainly larger than that of the square rail. The material of the square linear guide is nickel-chromium alloy which has better wear resistance after bonfire treatment, while the circular guide rail is mostly a layer of nickel-chromium alloy layer for steel, and there is no good bonfire treatment, and its wear resistance is obviously Not as good as a square rail. After a long period of work, the gap between the circular guide and the slider will increase rapidly, and the accuracy and stability will be greatly reduced. Nowadays, the domestic square rail brand used in woodworking engraving machines is based on Taiwan's Shangyin square rail. Many engraving machine manufacturers will also explain this to customers when making quotations, but it should be noted that many bad manufacturers use the silver rails. Wrong, but the matching slider uses the knockoff, because the position of the slider is not obvious and not noticed. Shenzhen Shicheng engraving machine expert!
