Matters needing attention for CNC machining of long material of aluminum profile

The aluminum beam, frame aluminum profile and frame aluminum profile of general equipment all need deep processing before they can be put into use. You'll need to saw, punch, tap, mill, and so on. Aluminum processing industry in the domestic general nothing more than ordinary machine tools, CNC processing center processing completed. Select the machine for the precision of aluminum parts and aluminum alloy.

Next we will learn about CNC long material processing notes

1. The speed of white steel knife should not be too fast.

3. When the workpiece is too high, it should be separated by different lengths.

4. After opening with a large knife, remove the remaining material with a small knife to ensure that the remaining amount is consistent.

5. Flat surface should be machined with flat bottom knife and less ball knife so as to reduce machining time.

7. The four corners of the table should be flat.

8. Where the slope is an integer, use the slope cutter machining, such as the pipe bit.

9. Before each process, figure out the remaining amount after processing in the previous process, so as to avoid cutting with empty or excessive machining.

10. Take a simple knife path as far as possible, such as shape, grooving, one side, and less surrounding height.

11. Don't ROUGH it if you can FINISH the WCUT.

12. Rough light first, and then finish; when the workpiece is too high, clear edge first, then light bottom.

13. Set tolerances reasonably to balance machining accuracy and computer computing time. When opening, the tolerance is set to 1/5 of the margin, and when light knife, the tolerance is set to 0.01.

14. Do a little more work to reduce the idle time. Think a little more and make fewer mistakes. Do more auxiliary line auxiliary surface to improve the processing condition.

15. Establish a sense of responsibility and carefully check each parameter to avoid rework.

16. Diligent in learning, good at thinking and making continuous progress. Milling non-planar, more ball knife, less use end knife, do not be afraid of the knife; The knife cleans the horn, the big knife refined repair; Do not be afraid of filling, filling can improve the processing speed and beautify the effect.

17. High hardness of blank material: better reverse milling

Low hardness of raw material: good milling

Machine accuracy good, rigid, finish machining: more suitable for milling forward, reverse more adaptive to reverse milling. It is strongly recommended to use down milling to finish machining the inner corner of the part. Rough machining: good reverse milling, fine machining: good milling along the tool material toughness, low hardness: more suitable for rough machining (large cutting amount machining), poor toughness of tool material, high hardness: more suitable for finishing (small cutting amount machining).
