How to adjust the precision of fiber laser cutting machine?
December 7, 2021
The adjusted laser cutting machine has very high precision and is widely used in cutting metal materials. The precision of fiber laser cutting machine determines the cutting quality of machined parts and the production efficiency of the enterprise. After the laser cutting machine is used for a period of time, there will be a certain error in the cutting precision, which is often caused by the change of focal length, Timely adjustment of cutting accuracy is extremely necessary. Therefore, mastering how to debug precision is the necessary knowledge of laser cutting machine.Now let's spread it to you.
In the whole production process of the laser cutting machine, the requirements for precision are also very high, but many times you will find that the precision of the laser cutting machine you just bought or the whole equipment has been used for a period of time is not so accurate. In this case, how to debug the laser? From the current situation, the precision of the laser cutting machine is in the process of debugging, Be sure to look at the focus above. The light spot of the focus laser is often easily modulated into a particularly small one. In this case, set the relevant settings of the special initial effect, and determine the position of a series of focus through the size of the spot effect. Of course, as long as you recognize that the light spot of the laser reaches a particularly small one, Then another location is a particularly good focal length. In this case, we can set the location of that place there, and then we can start a device like this.
In addition, when adjusting the first half of the laser cutting machine, you can also use some different props. For example, adjusting the focal length is often very important for debugging. Many accuracy can be mastered. At the same time, you can also move the laser up and down, because only in this way can you have a certain control over the height, Moreover, laser spots will vary greatly in large and small sizes. After many adjustments, we will be able to find a particularly suitable focus and determine the relevant locations.
In addition, after the laser cutting machine is installed, it can definitely slide on the top, and then simulate the relevant cutting patterns.
Attention shall be paid to the following points when debugging the accuracy of laser cutting machine:
1. when the spot of the focus laser is adjusted to a very small time, it is necessary to shoot the spot to create a special initial effect, and judge the focal length by the size of the spot effect. As long as we recognize the laser spot to a very small time, this position is a particularly good focal length, and then start processing.
2.In the first part of the laser cutting machine debugging, we can use some adjustment paper and workpiece waste to spot to determine the accuracy of the focal length position, move the position of the height of the upper and lower laser heads, and the size of the laser spot will change differently during spot shooting. Multiple adjustments are made at different locations to find out a particularly small spot position to determine the focal length and the particularly good position of the laser head.
3. After the laser cutting machine is installed, a scribing device will be installed on the cutting nozzle of the NC cutting machine, and a simulated cutting figure will be drawn through the scribing device, which is a 1m square. A circle with a diameter of 1m is set up, and four corners are diagonally affirmative. After the stroke is finished, the measuring tool is used to measure whether the circle is tangent to the four sides of the square. The affirmative affirmative affirmative value of the square diagonal is 2 (affirmative number is 1.41M), the central axis of the circle should be divided into square edges, and the distance between the axis and the two sides of the square to the intersection point between the sides of the square should be 0.5m. The distance between diagonal and intersection points can be measured, and the cutting accuracy of the equipment can be judged.
