What are the advantages and disadvantages of the linear guide of the woodworking engraving machine?

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 woodworking engraving machine accessories, straight The guide rail is an indispensable part, so today we will discuss the advantages and disadvantages of the linear guide rail of the woodworking engraving machine? The following are the advantages and disadvantages listed by Superstar CNC for reference.

The advantages of woodworking engraving machine linear guide

1. High positioning accuracy: When using a linear slide as a linear guide, because the friction method of the linear slide is rolling friction, not only the friction coefficient is reduced to 1/50 of the sliding guide, but the difference between the dynamic friction and the net friction also changes Is very small. Therefore, when the bed is running, there will be no slipping, and the positioning accuracy of um level can be achieved.

2. 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 slide rail, 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 bear the side load lighter. It is easy to cause poor machine operation accuracy.

3. Less abrasion can maintain accuracy for a long time: Traditional sliding guidance will inevitably cause poor platform motion accuracy due to oil film backflow, and insufficient sliding time due to motion time, resulting in wear of the contact surface of the running track, which seriously affects accuracy. The wear of the rolling guide is very small.

4. Use high-speed motion and greatly reduce the required driving horsepower of the machine: Since the friction force when the linear slide is moving is very small, only a small amount of power is required to make the bed move, especially when the work mode of the bed is frequent When running back and forth, 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.

5. Easy to assemble and interchangeable: When assembling, you only need to mill or grind the mounting surface of the slide rail on the table, and follow the suggested steps to fix the slide rail and the slider on the machine table with a specific torque. The alarm density during current processing. The linear slide rails are interchangeable, and the sliders or slide rails or even the linear slide rail groups can be replaced separately, and the machine can regain the guidance of this precision.

Disadvantages of woodworking engraving machine linear guide

1. The coefficient of static friction is larger than that of compasses, and it is easy to crawl at low speed (1-60mmmin)

2. Use the following rules for the same motor to reduce the use of the drive motor and increase a certain load

3. 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

4. Requires high precision and high cost of guide rail attachment surface

5. The surface is easy to rust
