The slider is able to convert the curved motion into a linear motion, and a good guide rail system can make the machine tool get faster feed speed. At the same speed, rapid feed is characteristic of linear guides. Since the linear guide is so useful, what is the role of the linear rail block play？
1. The driving rate is reduced, because the linear guide rail movement friction is small, as long as there is little power can make the machine move, the driving rate is reduced, and the heat generated by friction is more suitable for high-speed, frequent start and reversing movement.
2. High action accuracy, the movement of the linear guide rail is achieved by rolling, not only the friction coefficient is reduced to one-fiftieth of the sliding guide, but also the gap between the dynamic static friction resistance will become very small, so as to achieve stable movement, reduce shock and vibration, can achieve positioning, which is conducive to improving the response speed and sensitivity of the CNC system.
3. Simple structure, easy installation, high interchangeability, the size of the linear guide rail can be kept within the relative range, the slide rail installation screw hole error is small, easy to replace, install the oil injection ring on the slider, can directly supply oil, can also be connected to the oil pipe automatic oil supply, so that the machine loss is reduced, can maintain high-precision work for a long time.
There are two types of block: flange and square,the flange type is suitable for heavy moment load application because of the lower assembly height and wider mounting surface.
When installing, do not move the clipper in the slider in advance, otherwise it is easy to cause the steel ball in the slider to fall, and then can not be installed and used normally, At the same time, the clipper should also be installed to prevent the steel ball from falling when disassembling.
