　　使用直线导轨作为导向时，由于直线导轨的摩擦方式为滚动摩擦，不但摩擦系数降低滑动导轨的1/50，动摩擦力与静摩擦力的差距也变的很小。因此当负载平台运动时，不会有打滑的现象发生，可达到很高的定位精度2）减少磨损能长时间维持高精度When using linear guideway as guide, because the friction mode of linear guideway is rolling friction, not only the friction coefficient decreases to 1/50 of sliding guideway, but also the difference between dynamic friction and static friction becomes very small. Therefore, when the load platform moves, there will be no slippage, which can achieve high positioning accuracy 2) Reducing wear and maintaining high accuracy for a long time.

　　传统的滑动导轨，无可避免的会因为油膜逆流作用造成平台运动不良，且因运动时润滑不充分，导致运行轨道接触面的磨损，从而影响精度。而滚动导轨的磨损非常的小，所以设备能够长时间的维持高精度。

　　Traditional sliding guideways inevitably cause poor motion of the platform due to oil film countercurrent effect, and inadequate lubrication during movement, resulting in wear and tear of the contact surface of the running track, thus affecting the accuracy. The wear of rolling guide is very small, so the equipment can maintain high precision for a long time.

　　3）适用高速运动且大幅降低设备所需驱动动力由于直线导轨移动时的摩擦力非常小，只需要较小的力便能让负载平台运动，尤其是在设备工作方式为经常性往复运动时，更能明显的降低设备电力损耗。且因其摩擦产生的热量较小，可适用于高速运动。

　　3) It is suitable for high-speed movement and greatly reduces the driving power required by the equipment. Because the friction force is very small when the linear guideway moves, only a small force is needed to enable the load platform to move, especially when the equipment works in a regular reciprocating motion mode, it can significantly reduce the power loss of the equipment. Because the heat generated by friction is small, it can be applied to high-speed motion.

　　4）组装容易并具备互换性

　　4) Easy assembly and interchangeability

　　组装时只需要铣削或者研磨机床上导轨装配面，并按步骤将导轨和滑块分别以特定扭力固定在机床上，即能够重现加工时的高精度。滑动导轨的则很花费时间，且当导轨精度不良时又需要从新产花。直线导轨具有互换性，可分别更换导轨或者滑块甚直线导轨组，设备即可从新获得高精密度的导向。

　　When assembling, only need to milling or grinding the assembly surface of the guide rail on the machine tool, and fix the guide rail and slider on the machine tool with specific torsion step by step, which can reproduce the high accuracy of processing. Sliding guides take a lot of time, and when the accuracy of the guides is poor, they need to produce new flowers. Linear guides have interchangeability. They can be replaced by sliders or even linear guides. The equipment can obtain high precision guidance from the new.

　　5）润滑构造简单

　　5) Simple lubrication structure

　　滑动直线导轨使用润滑不足，将会造成接触面金属直接摩擦损毁机床，而滑动导轨润滑充足并不容易，需要在机床适当的位置钻孔供油。直线导轨则已经在滑块上装配油嘴，可直接以注油器打入油脂，也可换上专用油管接头连接供油管，以自动供油机润滑。

　　Insufficient lubrication of sliding linear guides will cause direct friction damage to the machine tool, while sufficient lubrication of sliding linear guides is not easy, and oil supply needs to be drilled in the appropriate position of the machine tool. Linear guides have been fitted with oil nozzles on the slider, which can be directly injected into grease by the injector, or can be replaced with special tubing joints to connect the oil supply pipe for automatic lubrication of the oil supply machine.
