Recently, many novice friends want to know how to choose the right tool when using CNC woodworking engraving machine? The so-called "good horse with good saddle", how to integrate resource advantages and complement each other?TBecause there are many kinds of CNC milling cutters used for woodworking, and there are also many kinds of milling cutters used for CNC milling cutters, how to choose the right one among the many tools? Let's analyze the Leapion laser for everyone.
The object of wood cutting is solid wood and wood composite materials. Solid wood can be divided into softwood, hardwood and modified wood. Wood composite materials include veneer laminate, plywood, particle board, oriented strand board, large particle board, gypsum particle board, cement particle board, hard fiber board, medium density fiber board, high density fiber board, blockboard, glued composite materials, etc. Some wood or wood composite materials are also decorated with single-sided or double-sided veneers.
In solid wood cutting, wood cutting is divided into longitudinal, transverse, end and longitudinal end, longitudinal and transverse end cutting according to the direction of the blade relative to the wood fiber.
According to the rotation direction of the machine tool axis and the feed direction of the wooden workpiece, the direction of the blade's inclination on the tool is determined.
The stability of the tool and the workpiece during the cutting process includes several aspects. The stability of the work piece refers to the smooth feeding of the wood work piece during the cutting process without jumping. Measures to strengthen the stability of the workpiece are mainly to reduce the center of gravity of the workpiece and increase the contact area of the woodworking CNC planer.
The surface quality of wood workpieces includes surface roughness, geometric dimensions and shape position accuracy.
1. For high-density board or solid wood processing, it is recommended to use a spine knife.
2. For multi-layer board or plywood processing, double-edged straight groove milling cutter is recommended. 3. For acrylic mirror processing, diamond processing tools are recommended.
4. For rough processing particle board processing, it is recommended to use multiple milling cutters.
5. For cork, density board, log, PVC board, acrylic large deep relief processing, single-edged spiral ball end milling cutter is recommended.
6. For cutting aluminum, it is recommended to use a special milling cutter for single-edged aluminum. Because the single-edge special aluminum milling cutter does not stick to the tool during processing, the speed is high and the efficiency is high.
7. For precision small relief processing, a round bottom knife is recommended.
8. For burr-free cutting process, single-edged, double-edged upper and lower cutting knives are recommended. The effect of the lower knife is that there is no burr on the upper surface of the processed product, and there is no shaking during processing.
9. MDF cutting process, it is recommended to use a double-tool large chip-ejecting spiral milling cutter, with two large-capacity chip flutes, and a double-edged design, which not only has a good chip evacuation function, but also achieves a good tool balance. When processing medium and high-density boards , No blackening, no smoking, long service life. It is very popular.
10. For acrylic cutting, single-edged spiral milling cutter is recommended. The characteristics of the single-edged spiral milling cutter are: smokeless and odorless during processing, fast speed, high efficiency, no chip sticking, and truly environmentally friendly. Its special manufacturing process ensures that the processing of acrylic does not burst, the extremely thin tool line (or even no tool line), and the surface is smooth and flat.
If the surface needs to be polished, it is recommended to use a double-blade spiral milling cutter.
1. The size of the jacket should be appropriate. Jackets with cross-sections, not round, worn, and tapered in the inner hole must not be selected, otherwise it will cause a sensation in the handle and fail to make aspirations.
2. The handle should touch the jacket gently, and the handle should be pierced firmly into the jacket and tightened. If the jacket has been used for a long time, the inner hole is deformed, it is necessary to replace the jacket immediately.
3. Always check the patience of the tool. If you use it bluntly, please replace it immediately. If you continue to use it, it will not only perform poorly, but it will also cause the knife to break.
4. When using woodworking CNC engraving machine, pay attention to that the thickness of the processed material cannot exceed the thickness that the cutting edge can cut, otherwise the knife will be broken or the engraving effect will be unsatisfactory.
5. For the cutting of different materials, it is necessary to select different tools and adjust the cutting speed reasonably.
6. During the working process of the engraving machine, the high-speed rotating knives are very sharp. Pay attention to the body, clothes and hair not close to the objects in the work to prevent accidents.
7. The recommended cutting speed should be balanced, and the speed should be consistent as much as possible to achieve a very good effect. The cutting is too long to stay, and the iron must be hit while it is hot.
8. The knives should be cleaned with special cleaning agents.
9. When the knives are not in use, applying butter can prevent the knives from rusting.
10. The tool cannot be polished or changed shape by itself.
