Aluminum alloy processing hand-board model to the most efficient
< br /> silicon to aluminium alloy corrosion effects.
Will be more than 12% Si alloy usually referred to as high silicon aluminum alloy, it is recommended to use diamond tool, but it is not absolute, increasing silicon content on the destructive force of the cutting tool is gradually increasing.
Some manufacturers in the silicon content is more than 8% when diamond tool is recommended to be used.
< br /> silica content in 8%
12% of aluminum alloy is a transition between interval, can use ordinary carbide, also can use diamond tool.
At the same time using carbide should use the PVD (
Methods, excluding aluminum, membrane thickness smaller tool.
Because the PVD method and the small film thickness to keep cutting tool to be more sharp cutting edges,
Or grew up in order to avoid abnormal film layer on the edge need to enough of blade, cutting aluminum alloy will not sharp)
And membrane material containing aluminum may make the blade film layer with the workpiece materials close cooperation with the combination of film and cutting tool substrate.
Because the hard coating for aluminum, nitrogen compounds, titanium, may be because of the carbide substrate with membrane layer peeling off when a small amount of blade spalling caused by crack.
< br /> Shanghai new regiment is recommended to use one of the following three types of cutting tools: < br /> 1.
Don't coating of super fine grain cemented carbide cutting tool < br /> 2.
Take not containing aluminum coating (
Methods of cemented carbide cutting tools, such as plating TiN and TiC < br /> 3.
With diamond tool < br /> tool chip space is larger, general advice in 2 teeth, rake Angle and back Angle (
Such as 12 ° -
After 14 °, including end tooth Angle)
< br /> if only general milling surface, can use a 45 ° Angle of indexable milling cutter, Lord with special aluminum alloy blade, should be better.
< br /> alumina in 1808 in the laboratory using electrolytic also become aluminum, in 1884 was used as building materials in the United States to the Washington Monument on the spire yet;
Aluminum to join all kinds of metal elements synthetic material of aluminum alloy has been building industry are widely used in each link.
Aluminium alloy plate thickness commonly used: advanced metal roofing (
And curtain wall)
System is commonly 0.
The common to two or more traditional.
