How to debug the cutting accuracy of the laser cutting machine?

How to adjust the laser cutting machine to make the best use of what it cuts? In fact, just like people, machines need frequent maintenance. In this way, the equipment can be maintained in a relatively good operating state. There are many components in the laser cutting equipment, and the maintenance period of some parts is relatively short. So it often needs someone to maintain it.

Adjust machine assembly to improve machine cutting results.

Rail Mounting:

When installing the guide rails, it should be kept parallel. When the laser equipment leaves the factory, it needs to be debugged repeatedly to ensure the cutting effect of each equipment that leaves the factory. If the guide rails are not parallel, there will be resistance when the machine runs, and most of the cut pieces have serrated edges, so the Y-axis guide rails need to be kept parallel.

The installation position of the beam and the coupling is not good: during the installation process of the beam and the coupling of the machine, if the screw is not locked, or the locking is oblique or loose, it will affect the cutting effect of the laser cutting machine.

Adjust the parameters of the laser machine and improve the cutting speed of the machine.

Machine parameter setting, the machine parameters need to be adjusted gradually during the cutting process. In general, if the machine is not adjusted properly, the cutting speed will be affected, or the speed or the effect. How to achieve the state of both speed and effect is our responsibility. It needs to be debugged according to the customer’s material. When leaving the factory, each parameter of the laser cutting machine is set, but it can be adjusted according to the user’s needs later. When setting parameters, pay attention to the following points:

Initialising speed:

As the name suggests, this setting is the speed at which the machine starts. First of all, the initial speed is not as fast as possible. In fact, if the speed is too fast, it may cause the machine to shake very much at the beginning.

Acceleration: Acceleration is a process of acceleration from the initial speed to normal cutting when the machine is in production. Similarly, there will also be a process of deceleration when preparing to end cutting. If the acceleration is too low, it will cause the machine to cut. Slow down.

Laser cutting machine precision debugging method.

When the spot of the focal laser is adjusted to the smallest, the point shooting is performed to establish the effect, and the focal length is judged by the size of the spot effect. As long as we look for the spot of the laser to the smallest, then this position is the suitable focal length for processing, thus Start working on machining.

In the front part of the debugging of the laser cutting machine, we can use some debugging paper and workpiece waste to determine the accuracy of the focal length position, and move the height of the upper and lower laser heads. Adjust different positions several times to find the smallest spot position to determine the focal length and the proper position of the laser head. The workpiece processed by the laser cutting machine has no burrs, wrinkles and high precision, which is better than plasma cutting. For many mechanical and electrical manufacturing industries, CNC laser cutting systems are often preferred over punching and molding processes because they can easily cut workpieces of different shapes and sizes; there is no need to repair molds, and it also saves time to replace molds, thereby saving processing costs, reduce the cost of the product, so it is more economical in general.
