Laser Cutting Parameters for Different Materials

The book explains in detail the key parameters for laser cutting of both metal and non-metal materials, including laser power, cutting speed and gas pressure. It also provides practical advice on cutting common materials such as stainless steel, aluminum, acrylic and wood, as well as a quick troubleshooting guide. This will help operators adjust equipment parameters flexibly to improve cutting accuracy and efficiency.

Why is parameter setting so important in laser cutting?

If you've used a laser cutter before, you know that if you don't set the parameters right, it's like trying to cut a steak with a blunt knife.If the power is too high, the edges will burn; if the speed is too slow, the material will distort. The temperaments of the different materials are also very different.Today we'll discuss how to deal with the "character" of common materials like metal, plastic and wood.

How to adjust the parameters of the metal material cutting.

The key to cutting stainless steel.

For example, for a 1-mm-thick stainless-steel plate, it is recommended that you start at 1500W, and control the speed at about 3 m / min.The nitrogen pressure must not be lower than 0.8MPa; otherwise the cut surface will turn black easily.If you get a rough edge, it's probably because the nozzle is too far from the sheet.

A small technique for cutting aluminum.

The material conducts heat too quickly, so we have to raise the power by 200 watts, and the speed needs to be slowed down to 2 m / min.Remember, aluminum reflects light strongly, so you should wear protective goggles.After cutting, the lens is wiped with alcohol, which the aluminum residue sticks to particularly well.

Non-metallic material parameter setup.

Parameters for acrylic cutting.

Don ’ t rush to turn up the power! An 80-watt laser is sufficient for 3mm-thick material, and at a cutting speed of 5m / min, you can get a glass-like finish.If the edges of the paper turn yellow, it is probably because the pressure of the air is not high enough; try adjusting the air compressor to 0.3 MPa.

Things to keep in mind when engraving wood.

Pine is a soft wood, and 60 watts at 8 meters per minute is just right.For hardwoods like elm, the speed must be reduced to 6m / min.Important Reminder: Do a smoke test before carving to make sure there is no fire hazard from the accumulation of sawdust.

Quick troubleshooting for common problems.

If the cut doesn't go all the way through, first check the lens to see if it is dirty.If the cut is crooked, check whether the guide rails are stuck.If there are burn marks on the back of the material, it's probably because the support columns on the work table are too close together, and it's time to switch to a honeycomb work surface.
