A00177.gifGrinding (Topic: 16220)

Grinding may be used for precision finishing, abrasive cutting, chamfering deburring or mechanical surface treatment. Hard and more complex alloys are better suited for grinding operations, because they are less prone to clog the abrasive wheel or belt. Grinding may be performed dry or in presence of a cutting fluid.

A00177.gifHigh speed machining (Topic: 16400)

The development of new machines has led to very high working speeds 1500ñ5000 m/min. This is used for milling where the milling tool rotates with up to 40000 rpm. High cutting speed, low cutting forces, smooth surface and low heat transfer are characteristic features for the method.

Special tools with aluminium design is available for i.e milling, turning, cutting and drilling where you can find larger space for chip transportation.

High speed milling of aluminium gives high dimension tolerances, thin sections and high precision. Up to 95% of an aluminium piece can be milled into chips.
