In addition to the wide range of physical and mechanical properties that aluminium alloys offers, aluminium parts can be finished in a variety of ways. These are some of the most common ones.
Aluminium is the second most plentiful metallic element on earth. In its pure or alloyed form, aluminium is also the second most widely used metallic material after steels. Among the most striking characteristics of aluminium is its versatility.
Aluminium alloys can be machined rapidly and economically. Nevertheless, some alloys are more common than others when it comes to their use in CNC machined parts.
Since the properties of aluminium alloys are so influenced by work hardening and heat treatment, the temper (strengthening treatment, if any) must be designated in addition to the alloy composition code.
The machine tool spindle provides the relative motion between the cutting tool and the workpiece which is necessary to perform a material removal operation.
A machining center is a highly automated machine tool capable of performing multiple machining operations under computer numerical control (CNC) in one setup with minimal human attention.
The wrought alloy designation system consists of four numerical digits, sometimes preceded by a capital letter. The first digit indicates the principal alloying elements, as described next; the second digit is the variation of that alloy; and the last two digits represent the specific alloy designation.
In this article we'll go over some of the top tips on how you can improve your designs and decrease cost while optimising your parts for manufacturing using CNC machining.
It is impossible to manufacture workpieces without deviations from the nominal shape. When these deviations are too large, the usability of the workpiece for its purpose will be impaired. Control and measurement of these deviations is therefore critical.
Turning is a machining process in which a single-point tool removes material from the surface of a rotating workpiece. The tool is fed linearly in a direction parallel to the axis of rotation to generate a cylindrical geometry.
At CNC Proto we specialise in the machining of non-ferrous metals, mostly 6000 and 7000 series aluminium alloys, and engineering plastics.
