1. High positioning accuracy
When a linear guide is used as a linear guide, because the friction method of the linear guide is rolling friction, not only the friction coefficient is reduced to 1/50 of the sliding guide, but the gap between dynamic friction and static friction also becomes very small. Therefore, when the bed is running, there will be no slipping, and the positioning accuracy of μm can be achieved.
2. Less wear can maintain accuracy for a long time
Traditional sliding guidance will inevitably lead to poor platform motion accuracy due to greasy countercurrent effects, and insufficient lubrication during motion, resulting in wear of the contact surface of the running track, which seriously affects accuracy. The wear of the rolling guide is very small, so the machine can maintain accuracy for a long time.
3. Suitable for high-speed movement and greatly reduce the required driving horsepower of the machine
Since the frictional force is very small when the linear guide moves, only a small amount of power is required to make the bed run, especially when the bed is in regular reciprocating operation, it can significantly reduce the power loss of the machine. And because the heat generated by friction is small, it is suitable for high-speed operation.
4. Can bear the load in the up, down, left and right directions at the same time
Due to the special structure design of the linear guide, it can bear the load in the up, down, left and right directions at the same time, unlike the sliding guide in the direction of the parallel contact surface, which can withstand lighter lateral load, it is easy to cause poor machine operation accuracy.
5. Easy to assemble and interchangeable
When assembling, you only need to mill or grind the assembly surface of the guide rail on the table, and follow the recommended steps to fix the guide rail and the slider to the machine table with a specific torsion force to reproduce the high precision during processing. The traditional sliding guide requires shoveling of the running track, which is time-consuming and time-consuming, and once the accuracy of the machine is poor, it must be shoveled again. Linear guide rails are interchangeable. The sliders or guide rails or even the linear guide rail groups can be replaced separately, and the machine can regain high-precision guidance.
6. Simple lubrication structure
If the sliding guide is insufficiently lubricated, it will cause direct friction and loss of the metal on the contact surface. However, it is not easy for the sliding guide to be sufficiently lubricated. It is necessary to drill a hole in the appropriate position of the bed to supply oil. The linear guide has a grease nipple on the slider, which can be directly injected with grease with a grease gun, or it can be replaced with a special oil pipe joint to connect to the oil supply pipe for lubrication by an automatic oil supply machine.
