How is it made (2)

Previously (How is it made (1)), we discussed Computer Aided Design (CAD).

We can now see how those ‘on screen’ designs progress to a first stage product.

Firstly – let’s look at what a Maestro True Digital Amplifier chassis looks like in CAD

As we progress, we can see this become a real product

 

The Raw Material

Blocks of aluminium are delivered the AVA Media.

A pallet of 250 of these billets weighs over 700Kg

Once the billets have been measured and checked they are processed in one of the high precision, high speed CNC vertical milling machines.

 

CNC Machining

Our machines, can cut away aluminium rapidly – yet still keeping within tight tolerances, we are talking tolerances of 0.003mm – yes 3 thousandths of a millimetre!

Below is a picture of the main cavity of the Maestro-50 being evacuated.

Once cut the base chassis need to have 3 other CNC operations carried out on them, before they can be inspected and forwarded for finishing and anodising.

Below, a shelf of semi-finished Maestro-50s await 2nd stage processing.

Little knobs too

The tiny volume control knobs are also made in the same process.  See below an image of them

Next we will look at the finishing and anodising processes.
