Milling machines for fabrication of aluminium have larger teeth pitches than equivalent tools for steel and therefore a more spacious groove for chips. As with other sawing, a high cutting speed is required for a good result.
A high quality surface demands high power and stability in the tool and feed mechanism.
There is a difference between end and peripheral milling machines depending on where the surface to be milled is situated in relation to the milling spindle’s central line.
The milling diameter should be at least 20% larger than the width of the surface being treated when surface milling with an end mill. 2/3 of the surface should be moved against and 1/3 with the cutting direction during milling. The milling teeth should move in the line of feed (down-feed milling) when milling peripherally (i.e. slab milling cutter, shank-end mill, side-milling cutter or spindle moulding cutter).
As with most machining, drilling should be carried out at a high speed. When using standard bits, they should be sharpened so as to reduce the pressure required and obtain a better result.
Special bits for aluminium are only required for deep holes or soft alloys. It is important to note that the hole will be considerably larger than the bit diameter when drilling in aluminium, especially when drilling in soft alloys.
A considerable amount of heat is generated when drilling deep holes, especially if the diameter is large. Cooling is therefore essential to avoid the hole contracting.
