Any product has its own advantages and defects, today we will talk about the excellent defects of the linear guide of carpenter engraving machine.
Carpenter engraving machine linear guides are as follows:
1. High positioning accuracy: When using linear slides as linear guides, because the friction method of linear slides is rolling friction, not only the friction coefficient drops to 1/50 of the sliding assist, but also the distance of the dynamic friction to the net friction changes. Very small. Therefore, when the bed is in operation, there is no slippage, and the positioning accuracy of the um level can be reached.
2. Low wear and tear can maintain accuracy for a long time: the traditional sliding guide, inevitably due to the oil film countercurrent effect, the channel movement accuracy is poor, and the sliding of the working track contact surface is insufficient due to insufficient sliding at the movement moment, 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 drastically reduce the driving horsepower required for the machine: Because the friction of the linear slide is very small, the bed can be moved with less power, especially in the bed. When reciprocating, it is possible to significantly reduce the power loss of the machine. And because of the small heat generated by friction, it can be applied to high speed operation.
4. It can accept the load in the up, down, left and right direction: Because the special structure of the linear slide is designed, the load in the upper left and the right direction can be accepted together, and the lateral load that is acceptable in the direction of the parallel contact surface is not light. It is easy to form a machine with poor precision.
5. Assembling is simple and interchangeable: only need to mill or grind the mounting surface of the slide rail on the bed, and follow the proposition to slide the slide rail and the slider to the machine with a specific torque. Reproduce the alarm density during processing. The linear slides are interchangeable, so you can get the precision from the replacement slider or the slide rail or even the linear slide group.
Carpenter engraving machine linear guide defects are as follows:
1. Static friction is larger than the coefficient of the compass, and it is easy to crawl at low speed (1-60mmmin).
2. When using for a long time, if the machine tool is slightly deformed, the working speed will be lowered, which directly affects the production capacity.
3. Equal motor uses the lower gauge to drive the motor nm to add a certain load.
4. The guide rail attachment surface is required to have high precision and large cost.
5. Appearance is easy to rust
