What volume of aluminum processing technology have?
3. Diamond Tool
Chip space tool to a large, generally recommended to use 2-toothed rake angle, relief angle should be large (eg 12 ° -14 °, inclusive tooth posterior horn).
If only the general face milling, you can use the main angle of 45 ° indexable face milling cutter equipped with a special aluminum processing blade, the effect should be better.
Tool recommends using one of the following three categories:
1. Not ultrafine particle coating of carbide cutting tools
2. Not with an aluminum-containing coating (PVD) method of carbide cutting tools, such as plating TiN, TiC, etc.
Because PVD method and a small film thickness of the tool remain relatively sharp cutting edge as possible (otherwise avoid abnormal growth of the film at the cutting edge of the blade needs to be sufficiently passivated aluminum cut will not sharp) and the aluminum-containing material layer may cause damage to the blade and tool combining film and the substrate layer and the pro-cooperation with the workpiece material. Superhard coatings because more aluminum compounds, nitrogen, three of titanium, cemented carbide substrate may be due to a small amount of flaking caused by tipping over when the film peeling.
Aluminum silicon content between 8% -12% of a transition section, you can either use an ordinary hard alloys, diamond tools can also be used. But the use of carbide should be used by PVD (physical layer) which contains no aluminum element, film thickness smaller tool.
Silicon carbide has a corrosive effect on. While the general will be more than 12% Si aluminum alloy known as high-silicon aluminum alloy, it is recommended to use diamond cutter, but this is not absolute, the silicon content gradually increased the destructive power of the tool is gradually increased. Therefore, some manufacturers in the silicon content of more than 8% on the recommended use of a diamond cutter.
