Woodworking engraving machine linear guide advantages and disadvantages




The advantages of woodworking engraving linear guides are as follows:
1. High positioning accuracy: When using linear slides as linear guides, since the friction of linear slides 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 net friction is also changed. Very small. Therefore, when the bed is running, there is no slip phenomenon, and the positioning accuracy of the um level can be achieved.
2. Less wear can maintain accuracy for a long time: the traditional sliding guide, inevitably, the platform movement accuracy is poor due to the oil film countercurrent action, and the sliding of the running track contact surface is caused by the insufficient sliding of the movement time, which seriously affects the accuracy. The wear of the rolling guide is very small. Therefore, the Taiwan machine 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 of the linear slide is very small, the bed can be moved with less power, especially when the bed is working. When running back and forth, it can significantly reduce the power loss of the machine. And because of the small heat generated by its friction, it can be applied to high speed operation.
4. It can bear the load in the up, down, left and right direction at the same time: Due to the special beam structure design of the linear slide rail, it can bear the load in the upper left and the right direction at the same time, unlike the sliding guide which can bear the lateral load in the direction of the parallel contact surface. It is easy to cause poor running accuracy of the machine.
5. Easy to assemble and interchangeable: As long as the assembly surface of the slide rail on the bed is milled or ground, and the slide rails are fixed according to the recommended steps, the sliders are fixed on the machine with a specific torque, which can be heavy The alarm density at the time of processing. The linear slides are interchangeable, and the sliders or slide rails or even the linear slide groups can be replaced separately, and the machine can regain the guidance of the precision.


The disadvantages of the woodworking engraving machine linear guide are as follows:
1. Static friction is larger than the coefficient of the compass, and it is prone to creep at low speed (1-60mmmin).
2. When using for a long time, if the machine tool is slightly deformed, it will reduce the running speed and directly affect the production capacity.
3. The same motor uses the lower gauge to reduce the use of the drive motor nm to increase the load.
4. The rail attachment surface is required to have high precision and high cost.
5. The surface is easy to rust
