The difference between the circular and square rails of the engraving machine

    Heaven and earth are round and infinite. People are among them, as if they are mustard. The engraving machine's round rails and square rails also have their own differences, mastering their differences, and using the freely carved more beautiful products.

    The round rail is a cylindrical linear guide, which requires limited support, so the rigidity is poor. The bearing capacity is high and the precision is general. Due to the relatively low cost of the round guide rail, short production cycle and easy installation, it has become a substitute for square linear guides in many occasions.
    The square rail refers to the square linear guide or the square hard rail. The linear guide is superior to the hard rail at the precision speed, but the hard rail is superior in rigidity, according to different machine tool structure uses. Linear guides feature high positioning accuracy, reproducible linear guide rail rolling motion, friction coefficient is particularly small, especially the static friction and dynamic friction is very small, even in the case of micro-feeding there will be no idling and slipping phenomenon, The resolution and reproducibility are optimal, so advanced positioning accuracy can be achieved. Low friction resistance for long-term accuracy. 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 friction contact surface wears the bottom, so the walking precision can be maintained for a long time. . The optimal design of the geometric structure of the high load capacity that can withstand four directions, can withstand radial, reverse radial and lateral loads, and maintain the walking accuracy, and can be easily applied by preloading and the number of sliders. It can improve performance and load capacity. Suitable for high-speed applications, the frictional resistance is small, the driving horsepower demand of the equipment is low, the energy saving effect is large, especially the motion wear is small, the temperature rise effect is low, and the mechanical miniaturization and high-speed demand can be simultaneously achieved.
