CNC Titan Aluminiomu

When CNC turning aluminum, the cutting tool remains in position while you rotate the workpiece to remove unwanted material. The CNC turning lathe finds use in CNC turning aluminum utilizing computer-fed instructions to convert the aluminum workpiece into desired shape.

You can consider these CNC equipment to machine aluminum.

Feed rate describes the travel by the tool in making a complete cycle. It also applies to workpiece’s where it is turned and the tool is held in position.

Apẹrẹ irinṣẹ

The tool configuration, say flute count, is vital in making or breaking an aluminum CNC machining process. For instance, having a low flute count (2-3) when working on aluminum ensures there is no chip build up.

Ohun elo Irinṣẹ

Aluminum is a soft metal and machining tools require sharp edges not prone to wear such as carbide.

Alternatively, there are tooling systems made from cobalt. However, this is for situations where there is no reactivity with aluminum.

Reactivity with aluminum can cause surface infringements especially at high temperature.

However, you can employ carbide with slight cobalt content to achieve desired toughness without deformation.
