Whether it is better to choose round rail or square rail for metal engraving machine, we can compare it from the characteristics of round rail and square rail. The characteristics of the round track metal engraving machine: the bearing capacity is high, but the precision is average.
Square rail metal engraving machine, square rail, also known as linear guide rail, has high positioning accuracy and good reproducibility. The rolling motion of the linear guide rail has a particularly small friction coefficient, and the difference between static friction and dynamic friction is very small. Even when there is a small amount of feed, there will be no idling slippage, so the positioning accuracy of μm level can be achieved. Low frictional resistance maintains accuracy for a long time. Can withstand high load capacity in four directions, the optimal design of the geometric mechanical structure can simultaneously bear radial, reverse radial and transverse loads, and maintain walking accuracy, and can be easily adjusted by applying preload and the number of sliders , 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 simultaneously realize the requirements of mechanical miniaturization and high speed.
It is not difficult to see from the above characteristics that the performance of the square rail is better than that of the round rail, but the cost of the round rail is relatively cheap, the production cycle is short, and it is easy to install. If it is not a high-hardness metal such as metal engraving stainless steel, a metal engraving machine with a round rail can also be considered.
