CNC Milling Brass/Copper

How to CNC Milling Brass/Copper to Make its Surface Shiny?

Method of CNC Milling Brass

1) Choose the appropriate cutting tool: When we do CNC milling on brass/copper material, hard alloy cutting heads such as tungsten steel are needed to ensure efficient cutting and smooth surfaces. At the same time, it is necessary to select appropriate tool size and cutting speed based on the milling depth and material hardness to improve machining efficiency.

2) Adjust the worktable angle: Adjusting the worktable angle can ensure that the brass material is placed at the appropriate angle under the cutting tool. This helps reduce vibration and tool wear, while achieving a smoother surface.

3) Use appropriate coolant: Brass/copper is a metal that is prone to oxidation, so it is necessary to use appropriate coolant during the milling process to reduce friction and heat. It is recommended to use water-soluble cutting oil or deionized water.

Precautions for CNC Milling Brass/Copper

1) Avoid excessive cutting: Special care should be taken when using cutting tools to avoid surface related problems caused by excessive cutting.

2) Proper control of cutting speed: Fast cutting speed, excessive cutting depth, or vibration during the cutting process can all cause uneven surfaces.

3) Keep cutting tools clean: Cutting tools should be kept clean and sharp to ensure high-quality milling surfaces.

4) Use appropriate CNC milling methods: Traditional transverse milling methods or long dynamic radial milling methods can achieve better milling results.

Tips and Suggestions

1) Reasonably choose suitable cutting tools, especially the radius of the cutting head, to reduce the difficulty of machining.

2) Through repeated experiments, the optimal process parameters are discovered to reduce processing difficulty.

3) Use a soft cloth to wipe the milling surface, do not use hard brushes or other cleaning tools.

The above are some methods, precautions, techniques, and suggestions for CNC milling brass/copper , which can help you mill a smooth and bright surface.
