1. High positioning accuracy
When using the linear slide rail as the linear guide, because the friction mode of the linear slide rail is rolling friction, not only the friction coefficient is reduced to 1/50 of the sliding guide, but also the gap between the dynamic friction force and the static friction force becomes very small. Therefore, when the bed is running, there will be no slipping phenomenon, and the positioning accuracy of µm level can be achieved.
2. Less wear can maintain accuracy for a long time
The traditional sliding guide will inevitably cause poor movement accuracy of the platform due to the countercurrent action of the oil film, and due to insufficient lubrication during movement, the wear of the contact surface of the running track will seriously affect the accuracy. The wear of the rolling guide is very small, so the machine can maintain the accuracy for a long time.
3. Suitable for high-speed sports and significantly reduces the driving horsepower required by the machine
Due to the fact that the friction force is very small when the linear slide rail moves, only a small amount of power is required to make the bed run, especially when the bed works in a regular round-trip operation, which can significantly reduce the power loss of the machine. And because the heat generated by friction is small, it can be applied to high-speed operation.
4. Can bear the load in the up, down, left and right directions at the same time
Due to the special beam structure design of the linear slide rail, it can simultaneously bear the loads in the upper, lower, left and right directions, unlike the sliding guide in the direction of the parallel contact surface, which can bear a lighter lateral load and easily lead to poor operation accuracy of the machine.
5. Easy to assemble and interchangeable
When assembling, as long as the assembly surface of the slide rail on the machine table is milled or ground, and the slide rail and the slider are fixed on the machine table with a specific torque according to the recommended steps, the high precision during processing can be reproduced. The traditional sliding guide requires to shovel the running track, which is both laborious and time-consuming, and once the machine has poor accuracy, it must be shoveled again. The linear slide rail is interchangeable, and the slider or slide rail or even the linear slide rail group can be replaced separately, and the machine can regain the high-precision guide.
6. Simple lubrication structure
If the sliding guide is not lubricated enough, it will cause direct friction loss of the contact surface metal to the bed table, and it is not easy for the sliding guide to be fully lubricated, and it is necessary to drill holes in the bed table at the appropriate position to supply oil. The linear slide has an oil nozzle installed on the slider, which can be directly injected with an oil injection gun. You can also replace it with a special YouTube connector to connect the oil supply YouTube to lubricate the automatic oil supply machine.
