What are the advantages and disadvantages of linear guides for woodworking engraving machines?
Woodworking engraving machines are used in more and more industries. There are always various models and configurations when choosing. How to choose, the advantages and disadvantages of accessories, sometimes each manufacturer will have different explanations, in the woodworking engraving machine accessories. Linear guides are an indispensable part, so today we will discuss the advantages and disadvantages of linear guides for wood engraving machines? The following are the five advantages and disadvantages we have listed for reference;
First, the advantages of woodworking engraving machine linear guide
1. Easy to assemble and interchangeable: As long as the assembly surface of the slide rails 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. 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.
2. 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 works. When running back and forth, it can significantly reduce the amount of machine power loss. And because of the small heat generated by its friction, it can be applied to high speed operation.
3. 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.
4. 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.
5. 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.
Second, the shortcomings of woodworking engraving machine linear guide
1. The surface is easy to rust
2. The same motor uses the lower gauge to reduce the use of the drive motor and increase the load.
3. The rail attachment surface is required to have high precision and high cost.
4. Static friction is larger than the coefficient of the compass, and it is prone to creep at low speed (1-60mmmin).
5. When used for a long time, if the machine tool is slightly deformed, it will reduce the running speed and directly affect the production capacity.
