Aluminium is the one common material where tool wear is usually not the limiting factor<\/strong>. Speeds are so high and the material so soft that a carbide edge can last a long time \u2014 the failures come from build-up edge, chip packing, and poor surface finish instead.<\/p>\n

Many shops run faster than 600 m\/min on wrought aluminium with polished \u5200\u7247; above roughly 1000 m\/min you are usually limited by the spindle, not the tool.<\/p>\n

\u724c\u53f7s that work<\/h2>\n

Our most-stocked non-ferrous grades: PD20, HS6120, HS7125, HS7225, HS8115, HS8125, AW100K<\/strong>.<\/p>\n

The typical aluminium grade is an uncoated or lightly coated, fine-grain, polished<\/strong> carbide. Polishing matters: a smooth rake face gives the chip somewhere to slide instead of welding on. Do not use a general-purpose steel grade on aluminium \u2014 the TiN\/TiCN coating has a high affinity with aluminium and will build up quickly.<\/p>\n

The three real problems<\/h2>\n

1. Built-up edge (BUE)<\/h3>\n

Aluminium welds to a rough or worn carbide edge, and the welded lump then tears away, taking carbide with it. The result is a torn surface and rapid edge degradation. Fixes: polished grade, higher speed, sharp positive rake, and plenty of lubrication.<\/p>\n

2. Chip evacuation<\/h3>\n

Aluminium chips are long and bulky unless the geometry breaks them, and in milling or deep holes they pack and re-cut. Fixes: sharp chipbreaker, high-pressure coolant or air blast, climb milling, and fewer teeth in the cutter.<\/p>\n

3. Burr formation<\/h3>\n

Ductile aluminium forms large exit burrs. Fixes: sharp edge (a worn edge makes it far worse), positive rake, higher speed, and avoid a zero-feed dwell at the end of the cut.<\/p>\n

Silicon content changes the whole picture<\/h2>\n

If you are machining high-silicon cast aluminium in volume and changing \u5200\u7247 every few parts, the answer is PCD, not a better carbide grade. Carbide simply cannot survive the silicon particles.<\/p>\n
