1. High positioning accuracy: When the linear slide is used as the linear guide, because the friction mode of the linear slide 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 net friction force also changes. is very small.
2. Less wear can maintain accuracy for a long time
3. Use high-speed motion and greatly reduce the driving horsepower required for the machine: Since the friction force of the linear slide is very small, only a small amount of power can be used to move the bed, especially when the working mode of the bed is frequent During round-trip operation, the power consumption of the machine can be significantly reduced.
4. It 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 bear the load in the up, down, left and right directions at the same time.
5. Easy to assemble and interchangeable: As long as the assembly surface of the slide rail on the table is milled or ground, the linear slide rail is interchangeable, and the slider or the slide rail or even the linear slide rail group can be replaced respectively. The machine can regain the guidance of this precision.
The disadvantages of the linear guide of wood engraving machine are as follows:
1. The coefficient of static friction is larger than that of the compass, and crawling is easy to occur at low speed (1-60mmmin).
2. When used for a long time, if the machine tool is slightly deformed, the running speed will be reduced, which will directly affect the production capacity.
3. The use of the same motor reduces the use of the drive motor nm and increases a certain load
4. It requires high precision of the guide rail attachment surface and high cost
