This is the easiest way to find the true focal distance of your lens.ġ. When the spot starts getting bigger, then you have just passed the focal point. Continue moving the table and making test spots on the wood surface. The spot size should have gotten smaller. Make another test spot using the "laser" button. Move the wood to a clean target location.
Move the table away from the lens just a small distance. The spot size will be larger than desire for engraving. Use the "laser" button to make a test spot on the wood. Adjust the focus such that the material is slightly too close to the focal lens. Place a piece of flat scrap material (wood) under the focal assembly. The optimum focal distance might be slightly closer or farther away from the lens. Please remember that the Chinese optics are not the best. You may be concerned that you are using the provided tool to place the focus at the prescribed distance, but the focus just doesn't seem right. Last, tighten the focal tube nut (or screw). Second, move the focal tube to the desired height above the material surface. First, loosen the focal tube nut (or screw). If the table will not move or is already moved to the top, then the focal tube has some adjustment to move/slide up and down about 1.5 inches. Most laser machines have a movable table height. You will not want to damage the table surface, material, or the focal assembly. Use the measurement tool while moving the table to the proper height. The normal adjustment method is to place the material on the worktable and then to move the worktable height such that the top surface of the material is at the focus spot of the laser beam. Other machines come with a feeler gauge that snuggly fits between the focal tube nozzle and the top surface of the material. Some machine come with a square piece or acrylic to match to a marker on the side of the focal tube.

The laser machine should have come with a manual height measurement tool. Having the smallest spot size will give us the best resolution. Whenever we want to engrave, we want to have the laser beam focused to the smallest spot and that spot located at the top surface of the material.
#Taskboard laser cutter how to
Given that the lens is mounted in the focal tube, the question is how to put the material at the optimum location to engrave or cut.įirst, think of what results are desired. The laser beam is concentrated to the smallest size at this "spot". For a 55mm lens, the laser beam passes through the lens and converges to the smallest point at about 55mm from the edge of the lens. The focal lens acts like a magnifying glass and sunlight. The laser beam is focused through the focal lens. In the same case, the cutting of stainless steel and aluminum will be very different accuracy, stainless steel cutting accuracy will be higher, and the section will be smooth. cutting the material is different, also will affect the precision of the laser cutting machine. When cutting, the laser beam is to taper down, when the thickness of the workpiece cutting is very large, cutting accuracy will be reduced, cut out the gap will be very large.Ĥ. Therefore, the precision of the working table is also a very important factor to measure the accuracy of the laser generator.ģ. If the accuracy of the working table is very high, then the accuracy of the cutting will be improved. It shows that the precision of laser cutting machine is very high, and the quality is very high.Ģ. If the spot is very small, the cutting accuracy is very high, and if the gap is very small after cutting. the size of the laser coagulation of the laser generator.
Therefore, how to confirm the cutting precision whether qualified will be from the following four factors consideredġ. We confirm a laser cutting machine manufacturer is excellent, the cutting precision is the first standard. Industrial laser cutters are used to cut flat-sheet material as well as structural and piping materials.įactors Influencing on the Dimensions Accuracy in Laser Cutting The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish. A typical commercial laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The laser optics and CNC (computer numerical control) are used to direct the material or the laser beam generated. Laser cutting works by directing the output of a high-power laser most commonly through optics. Laser cutting is a technology that uses a laser to cut materials, and is typically used for industrial manufacturing applications, but is also starting to be used by schools, small businesses, and hobbyists. Ou can find the normal solution about laser cutting machine and laser cutting process.
