All steps For Cnc Router Machine To Make 3D Signs LED Letters:
1. Material selection: If you want to do engraving, the first step is to consider cutting and engraving materials. Generally speaking, the acrylic sheets we use are all prescribed materials. According to customer needs, we first choose a similar material , It is bigger than the customer's stipulation, and it is impossible to make it smaller.
2. Cutting: After the material is selected, the size is definitely difficult to be the same as the size required by the customer. When cutting, we have to choose the tool according to the thickness of the material. Boards of 5mm or more can be punched directly with a saw. Hook out the shallow wire groove, and then break the board with a knife. If you use a chainsaw, you must have two people together to ensure the balance of strength. The cutting step is very important. If you are not careful, you can destroy this piece of material.
3. Smoothing: The undulating acrylic sheet can be directly pushed and flattened with a plane. If there is no electric planer, it can be roughed with a grinder, and then placed on the belt machine for smoothing. The thin-shaped board is clamped together with a pressure iron clamp at the same time, and it is flattened and straightened with an electric planer or an abrasive belt machine. In this way, work efficiency can be improved, and the uniformity of the size of multiple plates can also be ensured. Professional manufacturers generally have special iron clamps to clamp and clamp the large organic sheet firmly, and then use an electric planer to push it flat. For small area boards, clamp and push flat with bench vise, the effect is also very good.
4. Polishing: The polishing process is to make the acrylic sheet smoother. Some scratches on the acrylic sheet should also be polished. Use sandpaper to grind the board fine, and then polish it with a polishing machine. When polishing, you should often use some polishing soap to apply it, which can speed up the speed.
5. Bending: Processing various display racks with organic plates often requires bending the plates into various angles. According to the length of the bending line, a number of heaters of different lengths can be self-made. The heaters are made of flat aluminum alloy profiles. Method: First, cut a 3~5mm groove line on the aluminum profile so that the heat of the heating tube can overflow from there. Use hard wood boards on both sides of the groove line to play the role of heat insulation and non-stick board. Then, fix the quartz heating tube in the aluminum tube with an iron clip and connect the power cord to use. When the organic board is bent, use a hook knife to draw a shallow line, so that the folded corner line can have both sides and the size is accurate. During the heating process, one side of the heating wire of the organic plate must be pressed with square wood, so that the heating wire will be heated evenly, and the folded corners will be straight, and there will be no pile of meat or local cracking. Different bending angles require wooden molds with different angles.
