1、定位精度高。使用直线导轨作为线性导引时，由于直线导轨的摩擦方式为滚动摩擦，不仅摩擦系数降低滑动导引的1/50，动摩擦力与静摩擦力的差距亦变得很小，因此当床台运动时，不会有打滑的现象发生，可达到超高精密级（um）级定为精度。

1. High positioning accuracy. When using the linear guide as the linear guide, because the friction mode of the linear guide is rolling friction, not only the friction coefficient is reduced to 1/50 of the sliding guide, but also the difference between the dynamic friction and the static friction becomes very small. Therefore, when the bed table moves, there will be no slippage, which can reach the ultra-high precision level (um).

2、磨耗少能长时间维持精度。传统的滑动引导，无可避免的会因油膜逆流作用造成平台运动精度不良，且因运动时润滑不充份，导致运行轨道接触面的磨损，严重影响精度，而滚动导引的磨耗非常小，故机台能长时间维持精度。

2. Less wear can maintain accuracy for a long time. The traditional sliding guide will inevitably lead to poor movement accuracy of the platform due to the counter-current effect of the oil film, and due to the insufficient lubrication during the movement, the contact surface of the running track will be worn, which will seriously affect the accuracy. However, the wear of the rolling guide is very small, so the machine can maintain the accuracy for a long time.

3、使用高速度运动且大幅降低机台所需驱动马力。导轨丝杠厂家提醒，由于直线导轨移动摩擦力非常小，只需较小动力便能让床台运行，尤其是在床台的工作方式为经常性往返运动时，更能明显降低机台点力损耗量，且因其摩擦产生的热度较小，可适用于高速运行。

3. Use high speed movement and greatly reduce the driving horsepower required by the machine. The guide rail lead screw manufacturer reminded that because the moving friction of the linear guide rail is very small, the bed table can be operated with only small power, especially when the bed table works in a regular round-trip motion, which can significantly reduce the loss of point force of the machine table, and the heat generated by its friction is small, which can be applied to high-speed operation.

4、可同时承受上下左右的负荷。由于直线导轨特殊的束制结构设计，可同时承受上下左右方向的负荷，不想滑动导引在平行接触面方向可承受的侧向负荷轻，易造成机台运行精度不良。

4. It can bear up, down, left and right loads at the same time. Due to the special beam structure design of the linear guide rail, it can bear the load in the upper, lower, left and right directions at the same time, and the sliding guide can bear light lateral load in the direction of the parallel contact surface, which is easy to cause poor machine operation accuracy.

5、组装容易并具互换性。组装时只要铣削或研磨床台上导轨之装配面，并依建议之步骤将导轨，滑块分别特定扭力固定于机台上，既能重视加工时的高精度，传统的滑动导引，则须对运行轨道加以铲花，既费事又费时，且一旦机台精度良，又必须在铲花一次，直线导轨具有互换性，可分别更换滑块或导轨是直线导轨组，机台即可重新获得高精密度的引导。

5. Easy to assemble and interchangeable. When assembling, it is only necessary to mill or grind the assembly surface of the guide rail on the machine table, and fix the guide rail and slide rail on the machine table with specific torque according to the recommended steps, which can not only pay attention to the high accuracy of processing, but also need to cut the running rail, which is time-consuming and time-consuming, and once the machine table has good accuracy, it must be cut once again. The linear guide rail is interchangeable, and the slide rail or guide rail can be replaced to the linear guide rail group separately, The machine can obtain high-precision guidance again.

6、润滑结构简单。滑动引导若润滑不足，将会照成接触面金属直接摩擦损耗床台，而滑动导引要润滑充足并不容易，需要在床台适当的位置钻孔供油，直线导轨则已在装置油嘴，可直接以注油枪打入油脂，亦可换上专用油管接头链接供油油管，以自动供油机润滑。

6. The lubrication structure is simple. If the lubrication of the sliding guide is insufficient, it will cause direct friction of the metal on the contact surface to wear the bed table. However, it is not easy for the sliding guide to be lubricated sufficiently. It is necessary to drill a hole in the proper position of the bed table for oil supply. The linear guide rail is already in the device nozzle, and can directly inject grease with the oil gun, or replace the special oil pipe connector to link the oil supply pipe, and use the automatic oil supply machine for lubrication.

在润滑前要先分清是油润滑还是油脂润滑，如果是油润滑，可以在滑块和丝杠的油孔处加油嘴，做配管润滑，集中供油，需要油泵等。如果是油脂润滑，用脂嘴和脂线，拉到好加油的位置即可。于润滑周期的话，如果机器运转不是非常频繁，周期一般是3个月内保养。润滑时，一般要把原有的脏油顶出去。更多相关内容就来我们网站http://www.jngongrun.com咨询！

Before lubrication, it is necessary to distinguish between oil lubrication and grease lubrication. If it is oil lubrication, the oil nozzle at the oil hole of the sliding block and the lead screw can be used for piping lubrication, centralized oil supply, oil pump, etc. If it is grease lubrication, use grease nozzle and grease line to pull it to a good position for oil filling. As for the lubrication interval, if the machine does not run very frequently, the interval is generally within 3 months. When lubricating, the original dirty oil should be ejected.
