For metal laser cutting machines, the cutting finish is more important. Then the finish of the metal laser cutting machine is determined by those factors? The first is the size of the pits removed by a single discharge. Its RZ is usually between 0.05u0026mu;~1.5u0026mu;. The second is the convex and concave stripes caused by commutation. Its RZ is usually between 1u0026mu;~50u0026mu;, and it is possible to be as large as 0.1MM or more. So what are the processing methods for its finish? Let's take a look together. The finish of metal laser cutting machine can be solved from the following aspects: 1. Appropriately reduce the pulse width and peak current, that is, reduce the size of the pit. 2. The guide wheels and bearings maintain good accuracy and smooth operation, reduce wire jitter and wire jump, and minimize the displacement of the wire movement trajectory. 3. Maintain the proper tension of the wire, and adjust the guide wheel and the power supply block so that the tension of the working area remains unchanged when the wire goes up and down. 4. The silk should not be too tight, and the water should not be too fresh. The new water is definitely beneficial to the cutting efficiency, but the cutting finish is not the best. 5. Add a splint on the upper and lower sides of the workpiece that is too thin, so that the reversing stripes are buffered within the splint range. 6. u200bu200bStable, accurate XY motion, good follow-up fidelity, and non-blocking crawling are also extremely important. 7. Maintain stable and loose frequency conversion tracking. 8. Re-cutting or multiple cuts with appropriate allowance. Scanning the cutting surface once with a small amount of cut will have a beneficial effect on dimensional accuracy and smoothness. Scanning three times in a row will basically remove the commutation stripes. As long as the machine tool has high repeat positioning accuracy and multiple processing with appropriate allowance, the smoothness of the cutting surface will be improved by one to two orders of magnitude. The effect is similar to that of slow-moving wire, and it does not take too much time. This is fast-moving wire cutting. One of the machine’s strengths. 9. Short wire can be used appropriately for thicker workpieces, and the reversing feed is less than half of the wire diameter at a time, which also conceals the reversing stripes. Of course it's just a cover up.
