硅对硬质合金有腐蚀效果。虽然一般将超越12%Si的铝合金称为高硅铝合金,彩涂铝卷引荐运用金刚石刀具,但这不是肯定的,硅含量逐步增多对刀具的损坏力也逐步加大。因此有些厂商在硅含量超越8%时就引荐运用金刚石刀具。
Silicon has corrosive effect on cemented carbide. Although the aluminum alloy with more than 12% Si is generally called high silicon aluminum alloy, and the diamond tool is recommended for color coated aluminum coil, this is not certain. The damage force of the tool is gradually increased with the increase of silicon content. Therefore, some manufacturers recommend the use of diamond tools when the silicon content exceeds 8%.
硅含量在8%-12%之间的铝合金是一个过渡区间,既可以运用一般硬质合金,也可以运用金刚石刀具。但运用硬质合金应运用经PVD(物理镀层)办法、不含铝元素的、膜层厚度较小的刀具。
The aluminum alloy with silicon content between 8% and 12% is a transition zone, which can use both general cemented carbide and diamond tools. However, the use of cemented carbide should be PVD (physical coating) method, does not contain aluminum, the film thickness of the tool is small.
由于PVD办法和小的膜层厚度使刀具坚持较尖利的切削刃成为可能(否则为避免膜层在刃口处反常长大需要对刃口进行足够的钝化,切铝合金就会不够尖利),而膜层资料含铝可能使刀片膜层与工件资料发作亲合效果而损坏膜层与刀具基体的结合。由于超硬镀层多为铝、氮、钛三者的化合物,可能会因硬质合金基体随膜层剥落时少数剥落造成崩刃。
PVD method and small film thickness make it possible for the tool to stick to a sharp cutting edge (otherwise, in order to avoid the abnormal growth of the film at the edge, it is necessary to passivate the edge sufficiently, and the cutting of aluminum alloy will not be sharp enough), and the film data containing aluminum may cause the affinity effect between the blade film and the workpiece data and damage the combination between the film and the tool matrix. Because the superhard coating is mostly composed of aluminum, nitrogen and titanium, the edge may collapse due to a small amount of peeling off of cemented carbide substrate with the film peeling off.

建议运用下列三类刀具之一:
It is recommended to use one of the following three types of tools:
1.不镀层的超细颗粒硬质合金刀具
1. Uncoated ultrafine cemented carbide tools
2.带未含铝镀层(PVD)办法的硬质合金刀具,如镀TiN、TiC等
2. Cemented carbide tools without aluminum coating (PVD), such as tin, tic, etc
3.用金刚石刀具
3. Using diamond tools
刀具的容屑空间要大,一般建议用2齿,前角、后角要大(如12°-14°,包含端齿后角)。
It is generally recommended to use 2 teeth, with large rake angle and rake angle (e.g. 12 ° to 14 ° including rake angle of end teeth).
假如只是一般铣面,可以用45°主偏角的可转位面铣刀,配用专门加工铝合金的刀片,应该效果更好。
If only general milling face, can use 45 ° main deflection angle of indexable face milling cutter, with special processing aluminum alloy blade, the effect should be better.
氧化铝在1808年在实验室使用电解还成为铝材,于1884年即被作为建筑资料运用在华盛顿纪念碑尖顶上至今;铝材参加各种金属元素合成的铝合金资料已被建筑工业广泛应用在各环节上。 铝合金常用板材厚度:高档金属屋面(和幕墙)体系的一般为0.8-1.2mm(而传统的一般要≥2.5mm).
Alumina was used in the laboratory in 1808 and became aluminum material by electrolysis. In 1884, it was used as building materials on the spire of Washington Monument; The information of aluminum alloy synthesized by various metal elements has been widely used in all aspects of the construction industry. Thickness of common aluminum alloy sheets: the thickness of high-grade metal roof (and curtain wall) system is generally 0.8-1.2mm (while the traditional thickness is generally ≥ 2.5mm)
