Small tricks in CNC Machining of metal parts In CNC machining, we often encounter some small problems, although these problems are small, but it will reduce our work efficiency, and the quality of the finished product will also have some impact. So how can we avoid some unnecessary small problems in processing? Let's tell you some tips in processing. 1. The speed of the white steel knife should not be too fast. 2. Coppersmiths use less white steel knives for rough opening, and more throwing knives or alloy knives. 3. When the workpiece is too high, it should be thickened with knives of different lengths in layers. 4. After opening the rough with a large knife, use a small knife to remove the remaining material to ensure that the balance is consistent before the knife. 5. Flat bottom knife machining, less ball knife machining to reduce processing time. 6. When the copper worker clears the corner, first check the size of the corner ER, and then determine how big ball knife to use. 7. The four corners of the calibration plane should be flat. 8. Where the slope is integer, apply the slope knife to machine, such as the pipe position. 9. Before doing each process, think clearly about the remaining margin after processing in the previous process to avoid empty knives or too many machining knives. 10. Try to take simple tool paths, such as shape, groove, single side, less around and equal height. 11. When walking WCUT, if you can go FINISH, don't go ROUGH. 12. When the shape of the light knife, first coarse light, then fine light, when the workpiece is too high, first light edge, then light bottom. 13. Set tolerances reasonably to balance machining accuracy and computer calculation time. When roughing, the tolerance is set to 1/5 of the margin, and for the light knife, the tolerance is set to 0.01. 14. Do more processes to reduce the empty tool time. Think a little more and reduce the chance of error. Make more auxiliary line auxiliary surfaces to improve the processing condition. 15. Establish a sense of responsibility and carefully check each parameter to avoid rework. 16. Be diligent in learning, good at thinking, and constantly improving. Milling non-planar, use more ball cutters, less end knives, do not be afraid to catch knives: small knives clear corners, large knives refinement; Don't be afraid of patching noodles, proper noodles can improve the processing speed and beautify the processing effect. 17. High hardness of blank material: good conventional milling Low hardness of blank material: better climb milling Machine tool has good precision, good rigidity, finishing: more suitable for climb milling, vice versa, more suitable for conventional milling Climb milling is highly recommended for finishing in corners of parts Rough machining: conventional milling is better Finishing: Climb milling is better Tool material has good toughness and low hardness: more suitable for rough machining (large cutting volume machining) Tool material has poor toughness and high hardness: more suitable for finishing (small cutting volume machining) Dongguan ganzoo Prototype Manufacturing Co., Ltd. has more than ten years of CNC machining experience, and has deep accumulation in various metals such as aluminum alloy precision parts machining, automation equipment spare parts machining and other specific projects. is a solution provider focusing on prototypes, high-precision parts, molds, on-demand manufacturing and other one-stop services.
