More and more industries use woodworking cnc router machines, there are always various models and configurations when choosing, how to choose the machine, the advantages and disadvantages of accessories, sometimes each manufacturer will have different instructions, in woodworking cnc router machines, linear guide Indispensable components, then, today we will discuss the advantages and disadvantages of the linear guide of the woodworking cnc router machine? The following 5 advantages and disadvantages are listed for your reference;
The advantages of woodworking cnc router machine linear guide are as follows:
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. 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. Therefore, the machine can maintain accuracy for a long time.
3. Use high-speed motion and greatly reduce the required driving horsepower of the machine: Since the friction force is very small when the linear slide is moving, 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.
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 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.
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. Linear slide rails are interchangeable, and the sliders or slide rails or even linear slide rail groups can be replaced separately, and the platform machine can regain the guidance of this precision.
The disadvantages of woodworking cnc router machine linear guide are as follows:
1. The coefficient of static friction is larger than that of compasses, and it is easy to crawl 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 same motor uses the following rules to reduce the use of the drive motor nm and increase a certain load
4. Requires high precision of the guide rail attachment surface and high cost
5. The surface is easy to rust
Each product has its advantages and disadvantages during use, and the same is true for woodworking cnc router machines. The advantages and disadvantages of woodworking cnc router machines have a great relationship with linear guides. The above are the advantages and disadvantages of linear guides. I hope to help everyone.
