Thanks to its mechanical properties, aluminum is ideally suited for the production of precise components with polished surfaces. An accuracy of one thousandth of a millimeter is no problem here.
To ensure that this accuracy is achieved, however, a few things must be taken into account when milling with aluminum cutters. First of all, there is the heat generated. Unlike wood and steel, aluminum can become soft and the cutting edge can stick together due to the strong heat generated during milling. The chips are then no longer removed, the chip space becomes clogged and the milling process stops. In the worst case, the milling tool breaks.
Reliable cooling is therefore indispensable when milling aluminum. Here you can choose between minimum quantity lubrication or compressed air. The second variant offers the advantage that it also blows through the chip space at the same time, which prevents clogging.
