How to adjust the cutting precision of CNC plasma cutting machine

Many customers always ask machine cutting accuracy when purchasing CNC plasma cutting machine. The precision of CNC plasma cutting machine can guarantee the 0.01mm/ step before leaving the factory. The accuracy error is about + 0.5mm. This error has been several times higher than that of the CNC plasma cutting machine itself, but this error is not formed by the equipment itself, but the thickness of the steel plate, the process, the cutting nozzle and the fire adjustment during the cutting process.

Testing the distance between diagonal and intersection points can distinguish the cutting accuracy of CNC plasma cutting machine. Most customers do not know the diagonal adjustment method when using CNC plasma cutting machine. Next we will give the customer a detailed introduction about the adjustment method of the numerical control plasma cutting machine's diagonal.

1. Choose to enter the "manual" function

2, select the "move" function in manual function, press "3" and input point increment (example 1000mm).

3, correspond to a point on the cart, make a clear mark on the rail. And let the cart go on the marking axis to move a point increment (such as 1000mm).

4, correspond to the points on the cart, make another mark on the rail, and measure whether the two distances are incremental distance (1000mm).

5, if the actual distance is larger than the point increment, then the pulse equivalent is smaller, otherwise the pulse equivalent is larger.

6, modify the pulse equivalent, in the main screen, select "parameters" setting, then choose the system parameters, modify the molecular equivalent of the corresponding value of the gear, and press "save". (warm tip: when moving 1000mm, 1mm corresponds to about 2.5 gear molecules. In this way, if the X axis of the machine tool is more than 1mm, X gear molecules should be added to about two.5. The Y axis is similar.

7, repeat third more until the walking distance is equal to the increment of point motion.

8. The pulse equivalent of the Y axis is measured by the same method and modified.

9, the pulse equivalent of the calibration is written in a position which is obviously not easy to erase, such as the back door of the chassis, so as to restore it in the future.

The above is to adjust CNC plasma cutting machine cutting diagonal accuracy of the method, we hope to it would be useful for you.
